SUMMARY:
The NE WRF effluent filtration system includes 12 filter cells constructed of poured-in-place concrete and incorporates the Hydro Clear® pulsed-bed sand filter process. The filters are designed to remove particulates; over time issues such as sand media loss, defective air lines, valve corrosion and leakage, ceiling cracks, and concrete floor spalling arise. These issues can lead to a reduction in process efficiency. The purpose of this project is to remove the existing filter media, clean and inspect the fouled media bed, and replenish it with new media. Additionally, it involves repairing damaged components. Tetra Tech will provide design, permitting, and bidding services associated with rehabilitation of the effluent sand filter system.
Project benefits are improved process efficiencies, ongoing rehabilitation, and restoration strategy of treatment infrastructure.
Tetra Tech was selected due to the ability of their professional personnel and past performance on similar projects. Tetra Tech is known for delivering a quality project and product. They have experience and understand different types of utilities as well as specific experience with Clearwater’s facilities.
It is anticipated the design will be completed within approximately 120 days from the date of council approval. Construction costs are estimated at $2.2 million, for a total estimated project cost of approximately $2.5 million for design and construction. Funding for the construction costs will be provided by a transfer of available Water & Sewer fund reserves to capital improvement project M1906, Northeast Plant R&R.
