How a land-grant cooperative extension water lab paired a splash pad with public water-quality demonstration programming
A composite cooperative-extension case study of a land-grant university extension water-quality laboratory whose adjacent splash pad operates as both a public-amenity destination and a public-facing water-quality demonstration platform showing families how splash pad water is tested, treated, and verified safe.
Summary
A land-grant university cooperative extension water-quality laboratory — operating under Oklahoma State University's broader extension mission and serving as a regional reference laboratory for municipal, agricultural, and rural-household water-quality testing across roughly 28 counties of central and northern Oklahoma — added a $480,000 demonstration splash pad explicitly scoped to pair public water-amenity programming with public-facing water-quality demonstration programming. The pad operates with a transparent recirculation skid visible behind a public-viewing window inside the broader water-lab visitor center, structured weekly water-quality demonstration programming where extension staff walk families through how splash pad water is tested and treated, and integrated programming connecting the pad to the broader extension-mission portfolio spanning rural-household water-testing programming, 4-H youth water-science programming, and broader community water-literacy programming. The capital structure combined a USDA NIFA capital pathway, a state extension-and-research-station capital appropriation, a regional rural-water-association contribution, and a structured donor campaign anchored on the water-literacy public-mission scope dimension.

Background: a land-grant cooperative extension water lab and a public water-literacy mission gap
The OSU Extension Water Quality Laboratory operates under Oklahoma State University's broader cooperative extension mission, serving as a regional reference laboratory for municipal water-quality testing, agricultural water-quality testing, and rural-household well-water testing across roughly 28 counties of central and northern Oklahoma. The lab processes substantial annual sample volume across regulated drinking-water testing, irrigation water-quality assessment, and rural-household well-water testing programming. By 2022, the lab's extension-mission leadership had identified a sustained public water-literacy gap, with the lab's substantial public-mission portfolio operating largely behind closed laboratory doors and broader public-facing water-literacy programming constrained to occasional county-fair demonstrations and structured 4-H youth water-science programming. The amenity-and-demonstration-pad scoping framework emerged through an extended extension-mission engagement period that recognized splash pad water as a substantively underused public water-literacy demonstration platform — splash pads are publicly-visible recirculating water systems that families experience directly, and the chemistry, filtration, and water-quality verification infrastructure inside a splash pad's mechanical room maps closely onto the broader water-system infrastructure that extension water-quality programming addresses across municipal, agricultural, and rural-household scope dimensions.
Demonstration-pad scoping: transparent recirculation and public-facing chemistry monitoring
The defining scoping feature of the project is the deliberate demonstration-pad orientation pairing public water-amenity programming with public-facing water-quality demonstration programming. The transparent-recirculation infrastructure includes a public-viewing window inside the broader water-lab visitor center looking directly into the pad's recirculation skid, with the filtration tanks, chlorination dosing, UV treatment, and pH-adjustment infrastructure clearly visible to visitors. A public-facing chemistry monitoring panel adjacent to the viewing window displays real-time water-quality readings including free-chlorine residual, combined chlorine, pH, ORP, turbidity, and water temperature, with structured signage explaining what each reading means and how each reading verifies water-safety. A structured weekly water-quality demonstration programming window — typically Saturday late-morning during the operating season — brings extension staff to the visitor center to walk families through how splash pad water is tested and treated, with extension staff drawing live samples from the pad's recirculation system, running structured water-chemistry tests using laboratory-grade equipment, and explaining how the same water-quality verification framework applies across municipal drinking-water systems, agricultural irrigation water, and rural-household well water. The demonstration-pad framework was developed in extensive coordination with the lab's extension-mission staff, broader OSU extension water-quality programming staff, and the regional rural-water-association infrastructure across the engagement period predating capital scoping.
Capital structure: USDA NIFA, state extension capital, rural-water association, and water-literacy donor campaign
The $480,000 construction cost was funded through a four-source capital structure deliberately calibrated across the demonstration-pad scope dimensions. A USDA National Institute of Food and Agriculture (NIFA) capital pathway contributed $185,000, drawing on NIFA's broader extension-and-research-capacity capital infrastructure, with NIFA program staff explicitly citing the project as a strong demonstration of integrated extension-mission public-facing water-literacy infrastructure. A state extension-and-research-station capital appropriation contributed $145,000 through OSU's broader extension-and-research-station capital pathway, with state-extension leadership explicitly citing the project's water-literacy public-mission scope dimension. A regional rural-water-association contribution of $90,000 came from the broader Oklahoma rural-water-association infrastructure spanning approximately 65 rural-water utilities across the lab's service area, supporting the rural-household water-testing dimension of the broader extension-mission scope. A structured water-literacy donor campaign raised $60,000 from approximately 240 contributing donors across the broader OSU extension-and-research-station donor infrastructure, with the campaign explicitly anchored on the water-literacy public-mission scope dimension rather than on more typical recreational-amenity donor narratives. The capital-structure design deliberately balanced contributions across pathways aligned with each of the project's water-literacy public-mission scope dimensions, reinforcing the demonstration-pad framework rather than treating the pad as standalone recreational infrastructure.
Programming integration: rural-household water-testing, 4-H youth water-science, and community water-literacy
The pad operates as integrated programming infrastructure across the broader extension-mission portfolio. Rural-household water-testing programming — the lab's structured outreach programming supporting rural-household well-water testing across the service area — uses the pad-and-visitor-center infrastructure as anchor programming infrastructure for periodic rural-household water-testing intake events, with structured programming connecting families' direct experience of pad-water-quality verification to the broader water-quality verification framework applied across rural-household well-water testing. 4-H youth water-science programming including the broader OSU extension 4-H water-science portfolio uses the pad as integrated programming infrastructure across structured weekly programming windows during the operating season, with structured 4-H water-science curriculum connecting pad-water-chemistry to broader water-system chemistry across municipal, agricultural, and rural-household scope dimensions. Community water-literacy programming including periodic public water-quality demonstration programming, structured public-facing water-system tours through the broader water-lab visitor center, and broader community water-stewardship programming uses the pad-and-visitor-center infrastructure as anchor programming infrastructure across overlapping programming windows. The integrated-programming framework was developed across the extension-mission engagement period predating construction and is documented in the project's broader extension-mission programming portfolio.
Replicability across other land-grant cooperative extension water lab contexts
The OSU Extension Water Lab model is replicable across other land-grant cooperative extension water-quality laboratory contexts where substantial extension-mission public-water-quality programming converges with sustained public water-literacy gaps and capital pathways supporting demonstration-pad scoping. Analogous water-quality labs where the pattern would translate include the broader land-grant cooperative extension water-quality laboratory infrastructure across the broader Land-Grant University System nationally — including labs at Texas A&M, Iowa State, Penn State, Cornell, UC Davis, and analogous land-grant institutions across the broader 1862, 1890, and 1994 land-grant institutional infrastructure. Several conditions affect replication success. First, substantial extension-mission public-water-quality programming infrastructure supporting demonstration-pad integration is essential — water-quality labs operating with thinner extension-mission public-facing programming infrastructure face structurally harder demonstration-pad scoping. Second, capital pathways supporting integrated USDA NIFA, state extension, and broader extension-mission donor infrastructure are uneven — labs operating in extension-funding contexts that constrain capital pathways face structurally harder capital structuring. Third, transparent-recirculation infrastructure supporting public-viewing of pad recirculation, filtration, and chemistry monitoring requires deliberate design integration — labs scoping demonstration pads without transparent-recirculation infrastructure face thinner demonstration-pad outcomes. Fourth, structured water-quality demonstration programming integration with broader extension-mission programming infrastructure is essential — labs operating with thinner extension-mission programming integration face thinner public water-literacy outcomes. Where these conditions converge, the cooperative-extension-water-lab splash-pad pattern produces uniquely strong combined extension-mission, public water-literacy, and demonstration-amenity outcomes.
Voices from the project
“Splash pad water is a substantively underused public water-literacy demonstration platform. Splash pads are publicly-visible recirculating water systems that families experience directly, and the chemistry, filtration, and water-quality verification infrastructure inside a splash pad's mechanical room maps closely onto the broader water-system infrastructure that extension water-quality programming addresses across municipal, agricultural, and rural-household scope dimensions. The demonstration-pad framework reflects that mapping operationally.”
“The transparent-recirculation infrastructure with the public-viewing window onto the filtration tanks, chlorination dosing, UV treatment, and pH-adjustment infrastructure has substantively changed how families understand water-system infrastructure. Children point at the chlorination skid and ask how it works, and extension staff walk them through it. That level of public water-literacy engagement was structurally unreachable through prior extension-mission public-facing programming.”
“The Oklahoma rural-water-association capital contribution reflects the structural significance of rural-household water-testing within the broader water-lab service portfolio. The pad-and-visitor-center infrastructure now anchors rural-household water-testing intake events across the service area, and rural-household water-testing program participation has substantively increased since the demonstration-pad opened.”
Lessons learned
- Scope the project deliberately around demonstration-pad integration with the broader extension-mission public-facing water-literacy portfolio rather than treating the pad as standalone recreational infrastructure; integrated demonstration-pad scoping substantively amplifies extension-mission public-water-literacy outcomes.
- Build transparent-recirculation infrastructure with public-viewing windows onto the recirculation skid and a public-facing chemistry monitoring panel into the project from the outset; retrofit demonstration infrastructure substantively underperforms integrated initial scoping.
- Pursue USDA NIFA capital pathways where the project demonstrates integrated extension-mission public-facing water-literacy infrastructure; the program-fit narrative writes itself for demonstration-pad projects scoped substantively.
- Engage regional rural-water-association infrastructure as both stakeholder consultation partners and capital-campaign contributors; rural-water-association engagement substantively reinforces the rural-household water-testing dimension of broader extension-mission scope.
- Develop structured weekly water-quality demonstration programming staffed by extension water-quality programming staff; without staffed demonstration programming the transparent-recirculation infrastructure substantively underdelivers public water-literacy outcomes.
- Integrate the pad with rural-household water-testing programming, 4-H youth water-science programming, and broader community water-literacy programming rather than operating standalone amenity programming; integrated extension-mission programming substantively amplifies public water-literacy reach.
- Document demonstration-program participation, rural-household water-testing program participation, and broader public water-literacy outcomes through structured measurement methodology; outcome data substantively strengthens institutional legitimacy across NIFA, state extension, and broader extension-mission funding pathways.
FAQ
How does the transparent-recirculation infrastructure operate, and what equipment is visible through the public-viewing window?
The transparent-recirculation infrastructure operates through a deliberately-designed public-viewing window inside the broader water-lab visitor center looking directly into the pad's recirculation skid mechanical room. Equipment visible through the viewing window includes the primary recirculation pumps, the high-rate sand-filter tanks, the chlorination dosing skid with chemical-feed pumps and day tanks clearly labeled, the UV treatment chamber with operating-status indicator visible, the pH-adjustment infrastructure including dosing pumps and chemical-feed tanks, and the broader plumbing-and-instrumentation infrastructure connecting the pad to the recirculation system. Adjacent to the viewing window, a public-facing chemistry monitoring panel displays real-time water-quality readings drawn from the pad's broader sensor infrastructure including free-chlorine residual, combined chlorine, pH, ORP, turbidity, and water temperature. Structured signage explains what each reading means, what regulatory thresholds apply, and how each reading verifies water-safety across the broader water-quality verification framework.
How does the structured weekly water-quality demonstration programming operate, and what topics are covered?
Structured weekly water-quality demonstration programming operates Saturday late-morning during the operating season, with extension water-quality programming staff bringing laboratory-grade equipment to the broader water-lab visitor center for live water-chemistry demonstrations using samples drawn directly from the pad's recirculation system. Programming topics rotate across the operating season and include free-chlorine and combined-chlorine testing using DPD colorimetric methodology, pH testing using laboratory-grade pH probes with calibration demonstration, turbidity testing using nephelometric methodology, microbial testing using membrane-filtration methodology with broader explanation of incubation timelines, and broader water-quality verification framework topics connecting splash pad water-quality to municipal drinking-water, agricultural irrigation water, and rural-household well-water scope dimensions. Programming is structured to engage both children and adults, with structured questions-and-answers windows allowing families to ask extension staff substantive water-quality questions across the broader extension-mission scope. First-summer demonstration program participation reached approximately 6,400 across structured programming windows.
How does the project integrate with rural-household well-water testing programming specifically, and what outcomes have been observed?
Rural-household well-water testing programming integration operates through several integrated dimensions. The pad-and-visitor-center infrastructure anchors periodic rural-household water-testing intake events across the operating season, with rural-household well-water testing intake conducted at the visitor center and structured programming connecting families' direct experience of pad-water-quality verification to the broader water-quality verification framework applied across rural-household well-water testing. The broader extension-mission rural-household water-testing outreach programming uses the pad-and-visitor-center infrastructure as anchor programming infrastructure for rural-household water-testing awareness across the broader 28-county service area. Outcomes observed across first-year operations include substantively increased rural-household water-testing program participation across the service area, substantively increased rural-household well-water testing intake event attendance, and substantively stronger rural-household engagement with broader extension-mission water-quality programming across the post-intake period. The integration framework has been cited by analogous land-grant cooperative extension water-quality laboratories as a process model for demonstration-pad anchored rural-household water-testing programming.
