Explanation
1. BACKGROUND: This legislation authorizes the Director of Public Utilities to enter into a professional engineering services agreement with Black & Veatch Corporation for the Southerly Wastewater Treatment Plant (SWWTP) Biosolids Land Application Facility project. Black & Veatch Corporation, will provide design services and services during construction for this project.
The Department of Public Utilities has been working on incinerator upgrade designs to meet a Maximum Achievable Control Technology Standards (MACT) compliance date of March 21, 2016. The City has concluded that it is more advantagous to cease operation of the current Southerly Wastewater Treatment Plant (SWWTP) incinerator process and provide alternate means to handle the biosolids. Historically bio-solids have been disposed of utilizing the incineration process. With this project, the City plans to provide avenues to beneficially re-use biosolids. This project will provide infrastructure to the SWWTP in order to facilitate the maximum beneficial agricultural use of the plant's biosolids by land application including biosolids storage tanks with associated mixing and pumping equipment, liquid piping, load-out facilities, and an odor control system.
This project will also provide a storage structure for dewatered cake biosolids, piping to pump digested and undigested biosolids cake sludge simultaneously to the cake storage silos, and piping to link the biosolids land application tanks with the dewatering, thickening, and digestion processes. The primary goal of this project is to provide sufficient storage facilities, basic feed piping, and a temporary digested liquid biosolids load-out facility by March 21, 2016; thereby, reducing the need to incinerate. A second construction phase is envisioned to complete the construction of facilities to permanently eliminate incineration via expanded and enhanced land application programs.
