body
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 hold off on final design of the receiving station to be located at the Southwest Regional WWTF while staff locates a suitable off-site property for the receiving station and determines what upgrades will be needed to the receiving plant.
The anticipated time to complete these Part 2, Amendment #1, services is 252 days, yet the amendment will be in place until all services are performed. Once these services are complete, another amendment will be brought back to the Board for construction administration services approval.
The NCLF septage receiving station and leachate treatment facility will be designed to treat up to 50,000 gallons per day of septage discharge and up to 100,000 gallons per day of leachate.
The total not-to-exceed amount for both Part 1 and Part 2 services is $1,050,049.00.
This agreement is wholly funded by the U.S. Department of Treasury (USDT) through the American Rescue Plan Act (ARP), State and Local Fiscal Recovery Funds (SLRF).
RECOMMENDATION
Request Board approve Amendment No. 1 to Agreement 2022-025 with Hazen and Sawyer, P.C. to provide Part 2 professional engineering services for Septage Receiving Stations in the amount of $727,049.00.
FISCAL IMPACT
Funding is available in the American Rescue Plan Funds.
