DESCRIPTION
Due to newer restrictive Federal and State biosolid management regulations, there are fewer companies that are authorized to receive and dispose of biosolid materials. As a result, local private septage haulers requested the County consider providing septage receiving stations at its wastewater treatment facilities. This resulted in a Septage Receiving Station Feasibility Study, recently updated in July 2021. The study recommended building septage receiving stations at Wastewater Treatment Facilities (WWTF).
On May 3, 2022, the Board approved agreement 2022-025 with Hazen and Sawyer, P.C. to design two septage receiving stations to be located at the Northwest and Southwest Regional Wastewater Treatment Facilities. These services were to be broken down into parts and the original agreement provided for Part 1 Services in the amount of $323,000.00 to develop conceptual and preliminary design reports for each receiving station.
These services are now complete and the preliminary facility design report for the Northwest WWTF concluded that the North Central Landfill (NCLF) would be a better location by offering a site-ready, easily accessible location for a new septage receiving station. In addition, the NCLF site offers a cooperative project opportunity for the Utilities' and Waste & Recycling Divisions to treat both the excess leachate generated at the landfill, by complimenting the wetland leachate treatment system project currently under construction, as well as dispose of biosolids at the same location. After reviewing this report, the Utilities Division is recommending approval of Amendment #1 in the amount of $727,049.00 to provide for final design and bid support of the northwest receiving station at the NCLF and to ...
