AUGUST 21 • ENID'S WATER STORY • PART 8 OF 8

133 Years Later

Water from Kaw Lake finally arrives. Enid's water story began with a spring. The final chapter follows the system that now reaches roughly 70 miles east to Kaw Lake — the intake, pipeline, treatment plant, groundwater blend, financing and the question that matters most: what did Enid actually build?

Part 7 ended with a choice. Part 8 starts with what came next.

By 2014, Enid's engineers had compared more groundwater, new local reservoirs and Kaw Lake. Kaw was not the cheapest alternative on paper. It was the option that combined an existing reservoir, a different watershed, drought diversification and the ability to keep using Enid's groundwater system.^[2]

Then the question changed.

It was no longer Which source should Enid choose?

It became: How do you turn a lake roughly 70 miles away into drinking water in Enid?

MGD = million gallons per day. The 35% figure is the City's stated program goal, not an EPR claim that a 35% reduction has already been measured after sustained operation.^[4]

2015: the idea became an engineering program

The City's 2015 Annual Report marks a turning point. Engineering reported that preliminary work had begun to develop Kaw Lake as an alternate supply and that the City had received Oklahoma Water Resources Board water rights for an average demand of 18 MGD to supplement the groundwater well fields.^[3]

At that stage, the report described an intake, pump station, 66-mile pipeline, terminal storage and a treatment facility. It also said the design information would be used to obtain a water-storage contract with the U.S. Army Corps of Engineers.^[3]

What Enid actually built

The current City program page describes four major pieces: a micro-tunnel intake at Kaw Lake, roughly 70 miles of raw-water pipeline, a new 10.5-MGD treatment plant and distribution-system improvements. Garver's current program description adds important detail: the conveyance system includes 30- and 36-inch pipeline segments, booster pumping, terminal storage and a plant designed for a 21-MGD full build-out.^[4][5]

The new plant is doing something Enid's old system did not have to do

For generations, Enid's municipal supply was groundwater. The City's current Kaw page explains that the existing groundwater plants primarily chlorinate and fluoridate, while surface water requires a more extensive treatment process before it enters the drinking-water system.^[4]

Garver's published treatment-design account says the selected process includes pre-oxidation with ozone, conventional coagulation, flocculation and sedimentation, intermediate ozonation, biological filtration and post-filtration granular activated carbon — GAC — contactors. The GAC design was selected in part to control organics, taste and odor and disinfection byproducts, while giving the plant flexibility to address PFAS if testing and regulation require it.^[6]

10.5 MGD is not Enid's total water capacity

This is one of the easiest numbers in the project to misunderstand.

The new surface-water plant's initial treatment capacity is 10.5 MGD. That does not mean Enid is limited to 10.5 MGD across its entire water system, because the project was designed to operate alongside the groundwater wells.^[4][5]

The City's current FAQ says average daily demand is a little over 8 MGD and maximum daily demand has approached 15 MGD. Garver, the program manager and lead designer, says the program is designed to initially provide 10.5 MGD of advanced treatment and has provisions to treat up to 21 MGD at full build-out.^[5][6]

The wells were not abandoned. That is the point.

Part 6 showed that Enid's wells were still usable. Part 7 showed that Kaw's strategic value was diversification. Part 8 closes that loop.

The City's current project description explicitly says the new system moves Enid from sole reliance on groundwater to a mixture of surface water and groundwater. Its stated goal is to reduce average-day demand on the regional aquifers by about 35%, not to shut the well fields down.^[4]

Kaw was not built to erase Enid's groundwater system. It was built so the groundwater system would no longer have to carry the whole city by itself.

See it: open the actual maps and project records

For the finale, the best visuals are not generic water photographs. They are the maps, phase documents and engineering records that show what was planned and what was built.

Rights note: EPR links readers to the official City figures rather than rehosting contractor/base-map material as EPR-owned imagery. The early figures are planning-era snapshots and should not be mistaken for as-built maps.

The public schedule moved

The project did not arrive on the earliest public schedule.

The public dates show that the finish line moved by years. What they do not give EPR is a complete, single record explaining every schedule change, change order, construction constraint or cost effect along the way. That remains a legitimate closeout question rather than something to fill with assumptions.^{[3][12][13][11]}

How Enid paid for it

The public financing story has two layers: dedicated sales tax and long-term borrowing.

The City's current Kaw page says voters in 2016 approved a new ¾-cent sales tax and an extension of an existing ¼-cent tax to fund the Kaw project. Current City accounting describes 1% of City sales tax as going to the Kaw pipeline and associated water projects; the FY2025–26 budget says that dedicated 1% ends in 2052.^[4][10]

The City's FY2025 audited financial statements identify five outstanding note series — 2016, 2018A, 2018B, 2019A and 2020 — as financing or providing funds toward the Kaw Lake Water Supply Project.^[7]

Why the cost numbers look like they disagree

They are mostly answering different questions.

EPR calculation: $11,555,000 + $38,060,000 + $17,333,671 + $43,070,000 + $186,565,102 = $296,583,773 in June 30, 2025 principal balances for Series 2016, 2018A, 2018B, 2019A and 2020. The audit identifies each of those series as used for or toward the Kaw project.^[7]

The $53 million that was not a loan

In 2018, EPA selected Enid Municipal Authority to apply for up to $53 million in Water Infrastructure Finance and Innovation Act financing. EPA's own project sheet is explicit that selected borrowers still had to apply, complete credit review, negotiate terms and execute a credit agreement before receiving financing.^[8]

The City's FY2025 audit instead identifies the Kaw-related OWRB notes described above and does not list a WIFIA obligation. EPR therefore treats the $53 million as an invitation to apply, not money Enid received.^[7]

There was a voter-created oversight structure

The Kaw financing also came with a dedicated public oversight committee. The City says the Kaw Lake Funding Oversight Committee is responsible for checking that sales-tax proceeds are spent according to the governing ordinances, providing written recommendations when needed and delivering an annual progress report to the Mayor and Board of Commissioners by June 30.^[9]

That does not replace the City's annual audit or answer every project-closeout question. It does show that the dedicated sales tax was paired with a formal oversight mechanism.

Water rights, storage and one record we still want

Part 7 traced Enid's earlier Kaw permit — including its transfer to the Kaw Reservoir Authority and partial reduction after non-use — and then the City's return to Kaw.

By 2015, the City reported receiving new OWRB water rights for an average demand of 18 MGD. The same report said design information was being prepared for a U.S. Army Corps of Engineers water-storage contract.^[3]

EPR has not yet assembled the complete modern OWRB administrative file or the final federal storage-contract record into this series source set. Those documents could sharpen the legal history of the water Enid is now physically equipped to move.

What is complete — and what is not

August 21, 2026

The City's event notice describes the Aug. 21 ceremony as the official dedication and ribbon cutting for the Kaw Lake Water Treatment Facility and says it celebrates completion of the facility after years of planning, coordination, construction and partnership.^[11]

That is a real milestone.

It is also not the end of the record. Debt will continue. The system will have to be operated and maintained. The groundwater wells remain part of the supply. The published sources reviewed by EPR do not establish a date for expanding the surface-water plant to the 21-MGD full build-out. And future operating data will show whether the long-term aquifer-relief goal is being achieved.

Enid did not solve its water problem once. For 133 years, it kept building the next system before the last one was enough.

From a spring to a lake

Government Springs was here before Enid.

Then came the first waterworks. The giant wells. Underground galleries. Reservoirs. Pumps. Court fights over groundwater. Well fields that moved farther and farther from the city. Canton storage Enid never developed. Decades of planning. A return to Kaw. And finally a pipeline running back toward Enid from an existing lake to the east.

This story is not a straight line, and it is not a story in which every earlier decision was obviously right or wrong.

It is a story of layers.

The old Water Works did not make every later well unnecessary. The distant well fields did not make Canton irrelevant to the historical record. Choosing Kaw did not make the wells obsolete. And opening a new treatment facility does not end the need to measure cost, reliability, water quality and aquifer performance.

The spring is still part of the story. So are the wells. So is the lake.
