Executive Snapshot and Market Trajectory.

Global water treatment equipment demand keeps scaling directly with China's expansive municipal wastewater buildout and India's growing industrial effluent compliance base, since accelerating process-efficiency mandates reshape equipment selection well beyond legacy clarifier designs across municipal, industrial, and process water deployments worldwide, a shift accelerating each season each year.
Smart digital treatment monitoring and control systems grow fastest, since expanding process-optimization mandates and rising effluent-quality demand across additional treatment categories increasingly pushes plant operators toward connected monitoring architectures that legacy disinfection designs cannot match on real-time diagnostic accuracy, particularly among Chinese and Indian operators pursuing faster compliance audits. This urgency compounds as regulators now require documented effluent-quality data before renewing permits, while plant engineers favor suppliers offering certified process-optimization evidence.
East Asia commands the largest share of global demand, a position built over decades through Xylem and Kurita's founding treatment engineering scale and the region's concentrated municipal wastewater manufacturing base, a gap that keeps widening each procurement cycle. Competitive intensity centers on suppliers combining documented effluent-quality consistency with established municipal relationships, since smaller regional producers increasingly lose contract allocation to integrated equipment makers worldwide Smaller regional producers increasingly struggle to match this pace overall today.

Water Treatment Equipment Market Forecast Scenarios

water-treatment-equipment-market-size-forecast-scenario-1790818527084
Global water treatment equipment demand grew steadily between 2020 and 2025, as pandemic-era project delays gave way to sustained recovery driven by accelerating Chinese and Indian municipal infrastructure investment even as specialty steel and membrane component costs repeatedly delayed production runs worldwide. The historical growth rate ran near 5.8% annually across the period, accelerating through late 2024 as process-efficiency mandates gained traction.
The base case assumes continued Chinese and Indian municipal infrastructure investment, accelerating disinfection and smart digital conversion as plant operators pursue process-optimization and real-time efficiency performance across broader municipal and industrial deployment categories, steady biological treatment and sludge dewatering demand across established distribution channels, and emerging smart digital rollout across additional industrial applications, with equipment production capacity investment continuing steadily across East Asian producing hubs, while regulators mandate documented effluent-quality clauses before renewal.
Faster-than-expected mainstream adoption of smart digital treatment monitoring systems across additional mid-size Brazilian and African municipal operators, following precedents set by leading Chinese and Indian operators, could pull demand ahead of the base case timeline. Conversely, continued specialty-steel allocation constraints tied to global specialty-metals supply gaps could restrict capital investment below current expectations. A slower transition leaves clarifier volume commercially viable.

China's Wastewater Buildout Anchors the Smart Monitoring Transition

Global water treatment equipment manufacturing occupies a genuinely durable commercial position, since precise, consistent effluent-quality architecture gives leading suppliers a reliability advantage that smaller regional producers cannot always match under demanding continuous plant-operation conditions. That reliability has pulled municipal demand well beyond legacy undocumented alternatives into certification-validated categories, a gap that keeps widening as plant engineers demand traceable effluent-quality data. This dynamic strengthens with each successive procurement cycle nationwide.
MARKET CONCENTRATIONCR5 32%combined shipment share among top global equipment manufacturers
SMART MONITORING PREMIUM19-27%contract price increase for certified digital monitoring systems
LEADING COUNTRY SHARE15%share of global demand within China's municipal treatment base
MUNICIPAL DIRECT CONTRACT SHARE44%share of equipment sold through direct municipal and EPC contracts
FEEDSTOCK COST SHARE30%specialty steel and membrane share of total input cost
EQUIPMENT SERVICE LIFE15-20 yearstypical years of operational service under continuous plant use
Documented effluent-quality research still varies considerably by manufacturer, though. Leading global equipment manufacturers offer documented, peer-reviewed process-efficiency and contaminant-removal data using validated third-party testing methodology that municipal and EPC procurement teams can cite confidently in purchase decisions, while smaller regional producers often still offer undocumented untested equipment that limit buyer confidence considerably across most channels. Manufacturers who document credibly command stronger contract pricing.
Global municipal and EPC procurement teams increasingly specify documented process-efficiency and contaminant-removal data directly within purchase briefs, pushing manufacturers toward validation investment on smart digital launch timelines regardless of whether every disinfection platform has completed certification yet. This buyer-driven urgency creates real opportunity for manufacturers who can move fastest, though it compresses margins for smaller operations under deadline pressure.
"Water treatment equipment used to mean a strictly commodity clarifier tank nobody expected to combine documented effluent-quality consistency, embedded real-time diagnostics, and municipal-scale traceability into a single certified infrastructure asset. Now leading Chinese and Indian operators specifically request documented contaminant-removal data before qualifying a single manufacturer."

Market Trends

Regulators Increasingly Mandate Documented Effluent Quality Data

Global regulators increasingly mandate documented effluent-quality data directly within procurement contracts, citing genuine reliability-validation and total-cost-of-ownership demand that undocumented untested equipment cannot credibly address across scaled municipal and industrial networks worldwide today. This specification trend has become a stronger award catalyst than general cost marketing alone in several major municipal categories recently across the industry overall. Manufacturers who documented process-efficiency performance early now command stronger positioning than competitors confined to undocumented untested equipment, and this distinction increasingly determines municipal shortlist inclusion across most purchase cycles worldwide today. Several large municipalities now require this before any new award.
Market Impact: Lifts demand by 7 pct

Process Optimization Adoption Increasingly Drives Category Reformulation

Broadening global recognition of process-optimization criteria beyond its original limited-deployment origins increasingly incorporates documented contaminant-removal validation directly into equipment development, citing validated process-efficiency data that municipal procurement teams seeking substantiated engineering-endorsed claims across mainstream deployment categories worldwide and across emerging South Asian and Latin American industrial applications broadly today. This adoption trend has become a stronger catalyst than pure cost marketing among manufacturers targeting expanded documented-grade coverage across multiple mainstream platforms worldwide. Several manufacturers are expanding pilot lines to strengthen this evidence base further. Several large municipalities are extending this requirement into renewal negotiations too.
Market Impact: Lifts adoption by 11 pct

Market Opportunities and Growth Drivers

China's Municipal Treatment Scale Sustains Demand Growth

Xylem and Kurita's founding treatment engineering scale and the region's uniquely concentrated municipal wastewater manufacturing base continue driving demand for documented effluent-quality sourcing across municipal and direct-sourcing categories, positioning smart digital and disinfection formats favorably alongside other recognized premium technology categories that have successfully attracted buyer interest in recent years across most premium municipal channels worldwide, reinforcing sustained capacity investment across most producing regions each season broadly. Buyers increasingly confirm this driver's durability well into the next decade across most contract categories overall. Several suppliers are expanding capacity specifically to meet this rising demand.
Market Impact: Limits margin stability near 4 pct

Rising Industrial Effluent Compliance Investment Drives Growth

The expanding body of documented global industrial effluent compliance investment continues driving direct demand for documented smart digital sourcing, as procurement teams increasingly seek reliable, traceable certification-validated alternatives beyond legacy undocumented supply across multiple sourcing channels and premium platforms worldwide today, consistently and reliably each cycle overall across most channels. Regulators and quality-certification bodies across major markets continue tightening effluent-quality compliance timelines, reinforcing this driver's durability well into the next decade each season broadly today overall. Manufacturers investing early in documented smart digital capacity continue capturing the strongest share of this expanding demand pool.
Market Impact: Limits volume growth by 2 pct

Market Restraints and Challenges

Specialty Steel Costs Continue Limiting Pricing Predictability

Global water treatment equipment manufacturers remain fundamentally exposed to specialty steel and membrane procurement costs that cap how predictably manufacturers can offer stable contract pricing regardless of downstream municipal demand growth across categories and channels worldwide today. The root cause traces directly to concentrated global specialty-metals capacity volatility across major supplying regions that manufacturers cannot simply hedge away through additional design investment alone. Manufacturers are mitigating this by diversifying steel sourcing across multiple regional providers to reduce single-origin exposure, and manufacturers with diversified sourcing networks weather these swings considerably better than single-provider operators overall today.
Market Impact: Expands documented demand 8 pct

Mature Clarifier Segment Constrains Volume Growth

Global water treatment equipment expansion still faces genuine long-term volume constraints as mature clarifier applications remain commercially adequate across smaller municipal budgets lacking smart digital requirements in several developing markets, leaving manufacturers uncertain about complete contract feasibility in categories requiring documented, consistent long-cycle deployment planning across most global markets today. The root cause lies in untested-grade equipment remaining cost-competitive for budget-constrained buyers across most price-sensitive categories worldwide. This eases gradually as documented smart digital platforms prove their value over time, widening viable coverage steadily each season overall today, and buyers gradually reward manufacturers who commit early to this shift.
Market Impact: Expands diagnostics demand 13 pct

Capturing Value Through Documented Effluent Quality

With undocumented untested equipment facing intensifying substitution pressure across global municipal channels, manufacturers increasingly capture premium value through documented effluent-quality depth, digital breadth, and municipal partnerships across categories worldwide, and this hierarchy continues shaping distributor allocation decisions each renewal cycle overall today. Manufacturers investing early in each lever tend to compound their advantage across successive cycles.

Building Formal Documented Effluent Quality Certification Programs

Global manufacturers investing in standardized, peer-reviewed effluent-quality documentation win preferred purchase allocation from municipal and EPC buyers willing to pay meaningfully more than undocumented untested alternatives command across categories and formats. This documentation requires sustained investment in process-efficiency testing infrastructure and ongoing contaminant-removal tracking across manufacturing operations and testing partnerships spanning multiple qualification cycles. Manufacturers offering documented standardized equipment report contract pricing running roughly 17% above standard undocumented untested equipment. This gap increasingly separates preferred manufacturers from those losing contract share across the sector broadly. Buyers increasingly request this documentation before any shortlist consideration.
Market Impact: Commands roughly a full 17 percent pricing premium

Securing Third Party Contaminant Removal Endorsement Programs

Global manufacturers investing in credible third-party contaminant-removal endorsement certification and validation partnerships win preferred allocation from premium-focused municipal buyers willing to pay meaningfully more than untested alternatives command across categories and channels worldwide today. This certification requires sustained investment in laboratory-audit partnerships and ongoing validation across smart digital applications and formats over multiple production cycles and audit periods conducted regularly and thoroughly across every facility. Manufacturers offering certified quality-tested equipment report contract pricing running roughly 13% above standard untested delivery agreements today. Manufacturers without established partnerships increasingly lose ground to faster-moving rivals across most categories.
Market Impact: Commands roughly a full 13 percent pricing premium

Direct Municipal Partnership Priority Access Program

Global manufacturers building direct partnerships with premium municipal agencies and EPC developers capture stickier, higher-value customer relationships than those selling purely through generic distribution channels serving less-differentiated commodity categories and formats worldwide today. This partnership approach requires sustained investment in dedicated technical support and flexible equipment configuration that premium municipalities specifically require from manufacturers reliably and consistently across markets and production cycles conducted regularly each season and audit period. Manufacturers with established partnerships report customer retention rates roughly 16% stronger than those selling predominantly through generic commodity distribution channels alone consistently today.
Market Impact: Improves customer retention rates by roughly 16 pct

Large Scale Specialty Steel Sourcing Diversification Plan

Global manufacturers investing in expanded large-scale specialty steel sourcing diversification and secondary provider qualification capture premium-format allocation that purely commodity untested alternative equipment cannot reliably match at comparable durability and margin levels across categories and formats worldwide today. This diversification requires sustained investment in dual-sourcing qualification and quality certification across production facilities and multiple production cycles and qualification audits conducted regularly and thoroughly across each facility. Manufacturers adopting large-scale diversification report format-specific contract pricing running roughly 11% above standard undiversified-format equipment consistently, and buyers increasingly expect this evidence upfront during initial negotiation stages each cycle.
Market Impact: Commands roughly a full 11 percent pricing premium

Who Controls the Margin Pool

Global water treatment equipment supply remains meaningfully fragmented, giving this market a CR5 of 32% since no single group of established water-treatment majors holds dominant share of the municipal contract volume this category genuinely requires, measured on global unit shipment volume. The gap between leading manufacturers and smaller regional producers centers on documented effluent-quality validation and large-scale specialty steel sourcing capacity rather than any single proprietary process alone.
Competitive activity plays out across three areas: building documented effluent-quality validation that satisfies municipal and EPC specification requirements, developing integrated smart digital formats that command premium pricing, and establishing direct municipal partnerships that offer sticky, recurring contract revenue. Manufacturers combining multiple capabilities increasingly separate themselves from smaller regional producers still confined purely to undocumented untested equipment. Several manufacturers now bundle documentation alongside multi-platform contract agreements directly.

Emerging pressure is coming from smaller Chinese and Indian equipment developers rapidly scaling documented effluent-quality positioning and direct-to-municipal relationships, particularly in categories where established European and American majors have struggled to match nimble regional cost competitiveness among price-sensitive municipal buyers. This trend could reshape rankings in premium smart digital categories even as R&D investment stays concentrated among established majors overall.

Competitive Moat and Risk Dimensions

XYLEM INC.

Moat: Founding treatment engineering scale

Xylem maintains an integrated presence spanning founding treatment-engineering distribution scale, documented effluent-quality research, and years of manufacturing relationships built through category leadership with its smart digital platform. This founding positioning gives it meaningful advantage negotiating long-term contract agreements with large municipal and industrial networks directly worldwide.
XYLEM INC.

Risk: Specialty steel cost exposure

Xylem's scale does not fully insulate it from specialty steel price volatility, since its contract volume still depends on securing adequate component capacity across dispersed regional sourcing cycles each season. The company has responded by diversifying steel sourcing partnerships across multiple regions to improve cost predictability.
ECOLAB INC. (NALCO WATER)

Moat: Founding brand credibility scale

Ecolab operates one of the most extensively integrated effluent-quality research and deployment platforms in the water-treatment specialty category, giving it unmatched positioning negotiating both distributor and municipal-community partnerships across dozens of applications worldwide. Competitors would need years of comparable deployment-scale building to close this credibility gap meaningfully across the global market.
ECOLAB INC. (NALCO WATER)

Risk: Brand differentiation pressure

Ecolab's growth remains fundamentally tied to differentiating its effluent-quality claims from a growing field of newer, more narrowly focused competitors each cycle, limiting pricing-power predictability. The company has responded by investing in additional documented deployment research to reinforce its credibility, since buyers increasingly value this diversification.

Signal: Confirms manufacturers are formalizing domestic municipal partnerships well ahead of anticipated demand growth nationwide this year.

Global Specialty Steel Cost Exposure

Global water treatment equipment cost breaks down primarily into specialty steel and membrane procurement, dedicated fabrication and tank-assembly overhead, and increasingly, documented effluent-quality testing overhead. Specialty steel and membrane components typically represent 28 to 36% of total production cost, a share that moves directly with global steel-price cycles given the input structure. This leaves manufacturers exposed to sudden pricing swings across regions.
Elevated specialty steel feedstock costs during 2021 and 2022 meaningfully increased production costs across the global industry, according to vendor disclosures consistent with broader China MIIT and European Commission reporting covering the affected period. Manufacturers without diversified steel-sourcing relationships absorbed most of this increase into margins during that window. Several manufacturers began qualifying additional provider networks across regions to reduce future exposure across most sourcing regions overall today.

Manufacturers lacking direct access to reliable steel capacity and validated smart digital technology carry meaningfully more cost exposure than integrated manufacturers with established sourcing relationships. This growing gap increasingly separates which manufacturers can offer competitive, documented pricing to premium municipalities and which struggle to remain commercially viable during periods of tight capacity supply. Regional access gaps continue shaping pricing outcomes across most producing markets today.
water-treatment-equipment-market-cost-volatility-analysis-1790818528026

Diversified Regional Steel Sourcing

Larger manufacturers increasingly diversify specialty steel sourcing across multiple regional providers and countries, reducing exposure to any single region's supply-shortage disruption risk directly and meaningfully across most sourcing regions today. This approach continues expanding steadily each year across the sector, strengthening supply reliability broadly across most producing regions and contract categories nationwide each cycle and renewal period.

Long Term Steel Provider Partnerships

Manufacturers increasingly establish long-term partnerships directly with specialty steel producers across major producing regions, securing more predictable capacity pricing and availability compared to relying entirely on open-market spot sourcing arrangements. These partnerships extend across multiple production cycles, strengthening supply predictability each year across regions and sourcing programmes. This reduces reliance on volatile spot pricing overall.

Production Scale Consolidation Across Facilities

Leading manufacturers continue consolidating regional fabrication operations into larger, more efficient facilities, improving per-unit cost competitiveness compared to maintaining separate smaller processing operations that cannot achieve comparable economies of scale nearby. This trend keeps reshaping cost structures industry-wide, favoring manufacturers with scale advantages over smaller, dispersed regional competitors overall, strengthening pricing power each cycle.

Portfolio Architecture for Margin Defence

The global water treatment equipment market splits into three commercial tiers: screening and clarification units sold into broad value-adjacent applications, premium documented biological treatment and disinfection assemblies commanding meaningful certification premiums for effluent-quality formulation, and next-generation validated smart digital systems carrying documented traceable-reliability performance for demanding omnichannel municipal applications. Margin economics differ across tiers. Manufacturers position across tiers deliberately based on customer mix.
Manufacturers face a genuine strategic tension between defending mature clarifier volume and reallocating global steel capacity toward documented disinfection and smart digital formats that offer stronger long-term growth prospects. Those building capability across all three tiers capture the widest addressable revenue base, though doing so requires deliberate strategic repositioning and sustained investment most smaller organizations struggle to fund. Buyers increasingly evaluate manufacturers against this structure during shortlist review.

High-value margin pools concentrate overwhelmingly in premium disinfection and validated smart digital systems, where global municipal and industrial buyers pay materially more for documented traceable-reliability performance than clarifier buyers require. Manufacturers positioned to serve this tier alongside stable clarifier volume capture the clearest path toward sustained revenue as East Asia's infrastructure-driven demand continues expanding across most major segments.

Volume / Commodity-Adjacent Tier

Screening and clarification units sold into broad value-adjacent applications at competitive pricing with thinner manufacturer margins overall. Manufacturers compete here mainly on reliable delivery and landed cost rather than documentation. This tier still anchors meaningful volume.
Gross Margin: 21-27%

Premium / Certified Tier

Premium documented biological treatment and disinfection assemblies commanding meaningful certification premiums for effluent-quality formulation requiring documented quality content and consistent field-tested performance data. Manufacturers here maintain closer relationships with premium municipal customers directly.
Gross Margin: 27-34%

Sustainability / Regulatory / Next-Generation Tier

Next-generation validated smart digital systems carrying documented traceable-reliability performance for demanding omnichannel municipal applications. Manufacturers here typically maintain years of validated testing history and buyer trust across most channels and cycles.
Gross Margin: 34-41%
water-treatment-equipment-market-portfolio-architecture-1790818528215

High-value Sub-segments and Strategic Watch-out

Validated Smart Digital Format Supply

Validated smart digital format supply commands the strongest margins in the category and continues growing fastest as buyers seek documented reliability outcomes credibly and consistently across most channels and municipal contract categories, with manufacturers investing early continuing to set the pace each season. This gap continues widening each quarter.

Premium Documented Disinfection Format Supply

Premium documented disinfection format assemblies sustain strong growth as buyers increasingly require documented content matching engineering-endorsement expectations closely, and manufacturers investing early retain the strongest positioning across most contract renewal categories each season. Manufacturers here increasingly bundle documentation directly into multi-year contracts with municipal buyers.

Clarifier Grade Supply

Clarifier grade supply continues anchoring a meaningful share of global volume even as newer, higher-margin documented tiers expand steadily across the category worldwide, and this volume base remains commercially important across export markets and price-sensitive municipal categories worldwide. Export-focused manufacturers continue defending this volume base deliberately.

Specialty Steel Cost Risk Exposure

Continued dependence on concentrated global specialty-metals supply networks could meaningfully constrain category delivery capacity if capacity shortage or supply-cost inflation intensifies unexpectedly across major manufacturer relationships over the coming years, and manufacturers are actively diversifying provider networks across additional regions within the next few years overall.

Municipal Trust Anchors Equipment Purchasing

Once a municipality validates a specific manufacturer's effluent-quality performance on a deployed smart digital installation, switching manufacturers requires requalifying through new process-efficiency and reliability evaluation periods, creating a genuine annuity dynamic for manufacturers who secure this relationship first. Transition costs discourage casual switching between qualified manufacturers each cycle. Long-term multi-year municipal contract arrangements anchor this revenue base reliably across most producing regions.
Adoption depth varies meaningfully by end-use vertical. Premium disinfection and smart digital manufacturers exhibit the deepest stickiness given extensive documentation and requalification requirements, while mainstream clarifier purchasing shows comparatively shallower stickiness since buyers can rebid entry-tier contracts more freely without the same technical requalification burden. Premium municipal buyers show the deepest stickiness, while commodity accounts increasingly shop purely on price consistently across cycles today.

A younger generation of plant engineering managers increasingly evaluates equipment sourcing decisions through a documented-reliability-first lens by default, favoring manufacturers with verified effluent-quality performance over undocumented untested manufacturers competing purely on established cost advantages. This shift favors manufacturers with documented smart digital technology over commodity manufacturers competing purely on cost, a preference older cohorts rarely prioritized this heavily overall. Manufacturers increasingly tailor account teams to this generational shift directly.

Where Manufacturer Strategy Should Focus

These are among the four positions where our research anticipates prominent divergence between winners and laggards over the coming forecast period. Each is grounded in the demand model, the regulatory perimeter, and the announced capacity pipeline.
01 / SMART DIGITAL PIVOT

Redirect strategic investment toward smart digital formats

Smart digital format demand represents the fastest-growing, most attractive segment in this global market, while legacy clarifier demand offers only modest incremental growth regardless of pricing strategy adjustments made by manufacturers today. Manufacturers investing in documented effluent-quality sourcing now position themselves to capture this durable growth before more competitors recognize the opportunity, since building comparable documented consistency from scratch typically takes considerable time to establish credibly. Manufacturers who move first lock in the strongest early municipal relationships in this rapidly expanding category overall.
02 / DOCUMENTATION FIRST PRIORITY

Build standardized effluent quality documentation programs

Documented, standardized effluent-quality traceability increasingly determines which manufacturers win the largest premium municipal contracts, rewarding documentation investment over manufacturers still selling undocumented untested equipment into increasingly sophisticated global water-treatment categories. Manufacturers investing in substantiation infrastructure now position themselves to capture this segment before more competitors develop comparable documentation depth, since establishing trusted testing credibility typically requires considerable time and consistent batch validation. Early movers set the credibility bar that rivals are later measured against, and buyers increasingly reward decisive manufacturers.
03 / DISINFECTION FORMAT EXPANSION

Build dedicated traceable durability capability

Disinfection format demand continues expanding steadily, representing a genuine growth opportunity beyond legacy clarifier applications where competitive dynamics are comparatively mature and well established across most channels and price tiers. Manufacturers building dedicated disinfection documentation now position themselves to capture this segment before competitors develop comparable production depth, since establishing trusted buyer relationships typically requires considerable time and consistent quality delivery across multiple contract cycles. Manufacturers who wait risk ceding this ground permanently to faster-moving rivals with stronger municipal relationships already in place.
04 / FEEDSTOCK SOURCING RESILIENCE

Diversify specialty steel sourcing across regions

Concentrated global specialty-metals supply dependency leaves manufacturers exposed to cost and timeline risk specific to individual regions and their production cycles, a vulnerability that could meaningfully disrupt delivery during any future adverse component shortage or supply-cost shift affecting a key region or facility. Manufacturers building meaningful provider relationships across additional regions now reduce this concentration exposure before disruption arrives. Developing reliable alternative provider relationships typically requires multiple qualification cycles to establish trust firmly across new partner networks and geographies over time.

  3. Competitive positioning analysis showed that documented effluent-quality sourcing would meaningfully differentiate the client's water-treatment operations from competitors still using undocumented untested equipment currently in service.
  4. Manufacturer disclosure review confirmed both shortlisted equipment manufacturers maintained sufficient specialty steel capacity and documentation depth to support the client's anticipated delivery timeline reliably and consistently.
RECOMMENDED STRATEGY
Phase 1: Phase 1 (Months 1 to 2): Finalize equipment manufacturer selection and negotiate standardization terms, pricing, and delivery timeline commitments carefully with legal review. Phase 2: Phase 2 (Months 3 to 5): Complete smart digital fleet qualification testing and validate effluent-quality performance closely against the baseline, tracking milestones weekly. Phase 3: Phase 3 (Month 6): Launch fleet-wide standardization and monitor performance closely against existing internal benchmarks each week, adjusting sourcing terms promptly.
OUTCOME
The client launched its smart digital standardization programme on schedule and reported effluent-quality performance meaningfully ahead of its existing benchmarks within the first two quarters following launch (client-reported, unverified by MMA). The qualified manufacturer design has since become the client's standard fleet-wide sourcing choice across its full water-treatment network.
