Document Description
The “Wastewater Treatment and Effluent Percolation System Upgrade” project consists of development of a treated effluent subsurface percolation field on the western side of the Eel River, and supporting infrastructure upgrade of the City’s existing developed WWTP site. The new percolation facility is located approximately 2,800 feet from the water’s edge during low flow conditions. This site is more than 15 times further from the river than the existing percolation ponds and thus has much greater hydrologic separation from the Eel River. Under the proposed project, treated effluent would be pumped from the existing treatment plant under the Eel River through a new, directionally-drilled pipeline. A new pump station and piping modifications at the treatment plant would be required, along with a network of subsurface percolation pipes at the percolation site. The City’s Wastewater Treatment Plant (WWTP) is regulated under the North Coast Regional Water Quality Control Board (NCRWQCB) Order No. R1-2017-0005. The City obtained funding through the Clean Water State Revolving Fund (CWSRF) for planning of the project. The objective of the project is to address compliance issues related to the disposal of treated effluent and construct a new disposal system to replace the historic May 15th through September 30th use of the existing percolation ponds at the City’s plant and avoid the potential connection to the Eel River during the discharge prohibition period.
