The Claremore City Council met Monday to study a $45 million plan to improve the city’s water treatment plant in an effort to prevent future water quality issues.
Oklahoma Department of Environmental Quality (ODEQ) will implement new regulations later this year that the city will not be able to meet with its current infrastructure.
The council reviewed three different proposals from Garver USA, an engineering firm that previously worked to design the city’s new wastewater treatment facility.
Michael Graves, Garver project manager, presented the options ranging from $42 million to $57 million.
All three options were designed to meet the growing demand for water, preparing the city for a 20-year increase in population and address increasing ODEQ water quality standards.
Graves explained that each option comes at a different cost, but also a different long-term effectiveness.
The first option will feature the renovation and addition of a MIEX system, one clarifier, two filters and a clearwell to the current plant at a cost of $45 million.
The council appeared to favor this option after much discussion; although, no formal vote has been taken at this time.
A second option would combine city infrastructure to use both water treatment plants at a cost of $42 million.
This option is less expensive, but could be less predictable, according to Graves.
It includes the renovation of the “Robertson” water treatment plant and the addition of two water filters.
These filters would be retro-fitted to the existing structure, but will create higher operational costs requiring more equipment to perform the same function of the first option.
The final option costs $57 million and would require the city to build 21 miles of 30-inch pipeline to Pryor to purchase water from Oklahoma Ordnance Works Authority (OOWA).
This option would not allow the city to control water costs or quality.
The long travel distance could create quality issues requiring further treatment of the water before distribution in Claremore. Garver recommends the city select the first option and introduce it with a phased approach.
The first phase will include a $16 million expansion to water production. While the plant undergoes renovations the second phase will be tested, according to Garver.
The pilot-program will provide a better picture of the final cost of the MIEX system that will be added during phase two. The anticipated cost of phase two is $15 million, however it could be much lower after completing the pilot test, according to Graves.
The final phase would be an additional $13 million and will address water supply issues. The final step could be delayed until 2030 and would increase the city’s water intake capacity from Oologah Lake, according to Graves.
This will include adding new infrastructure to pump more water from Oologah Lake to Claremore Lake and the purchase of water from the city of Tulsa.
The primary concern for the city is the amount of Total Organic Carbon (TOC) and Disinfection Byproducts (DBPs) that result from the removal of TOC.
TOC is organic compounds that are found in the water that may be released from both natural and man-made sources.
All aquatic life naturally release TOC through their normal metabolism, excretion and eventual decomposition.
TOC can also come from the watershed around a water source, according to www. apps.sepa.org. By removing TOC, byproducts can be produced that are also monitored by ODEQ to insure safe drinking water.
