RCSD to hire treatment plant engineer
ROSAMOND — With construction underway to revamp and expand the Rosamond Community Services District’s wastewater treatment plant, District officials are looking to hire a consulting engineer to ensure it becomes operational as intended.
The Board of Directors on Wednesday will consider contracts with a firm for operations oversight for the expansion and to develop plans and policies for compliance with the state requirements and those of the Lahontan Regional Water Quality Control Board.
The meeting begins at 6 p.m. in the Board Room of the District offices, 3179 35th St. West.
The Board will consider two contracts with Bakersfield-based Aqua Operations. One will be for operation oversight during the expansion project, focusing on such items as considerations for testing and commissioning the plant and coordinating permit requirements, and a second contract to develop the policies and procedures required for its operation to meet regulations.
The total cost for the two contracts, $39,335, is included in the overall $15 million budget for the wastewater treatment plant project, according to the staff report.
The revamped and expanded plant is expected to open in spring 2021 with a new
name — The Rosamond CSD Water Reclamation Plant — to better describe its ultimate purpose.
In addition to handling the community’s wastewater disposal, the plant will recharge the underlying groundwater basin, providing additional groundwater for the District to pump.
The wastewater treatment plant project has been in the works for a couple years as a means of addressing more than one issue facing the District.
The District has been under an order from the Lahontan Regional Water Quality Control Board since November 2015 to reduce excess nitrates seeping into the groundwater from water treated to a secondary level at the wastewater treatment plant. The treated water is currently sent to evaporation ponds onsite, which have been found to be leaking.
An option to reline the ponds was deemed to be too costly and this alternative was developed.
This project will take the secondarytreated efuent, run it through the somewhat modified tertiary treatment equipment to remove nitrates, then percolate the resulting water into the ground.
This is intended to not only resolve the nitrate contamination problem with the regulators, but also recharge the aquifer, allowing the district to pump more groundwater.
The project calls for increasing the higherlevel treatment capacity of the plant from the 500,000 gallons per day to 1.27 million.
Once it is fully operational, the existing evaporation ponds will be cleaned of the “sludge” left behind and abandoned.
Three new percolation ponds, where the treated water will be allowed to soak into the ground, will be built as part of the project.
