Explanation

1. BACKGROUND: This legislation authorizes the Director of Public Utilities to enter into an engineering agreement with Andover Associates for professional engineering services for the Southerly Wastewater Treatment Plant (SWWTP) Post Aeration Diffuser Replacement project, CIP 650354-100000.

Two future renewals are anticipated. The scope of work for this project generally includes replacing the PVC pipe and post aeration diffusers. Due to age and exposure to UV, this equipment is failing and is no longer supported by the original equipment manufacturer. This project will also provide a comprehensive analysis of the post aeration system as a whole, including blowers, provide a structural analysis of the former mixing pads over the chlorination tanks, and provide an analysis and solution to issues with the effluent sample pump.
