Explanation
1. BACKGROUND
This ordinance authorizes the Director of Public Utilities to enter into a service contract with Synagro Central, LLC, through the City’s Invitation For Bid process, to provide ongoing residuals removal services for the Parsons Avenue Water Plant (PAWP) Residuals Removal and Disposal - Lagoon 3 project, CIP #690566-100001, in an initial amount up to $5,000,000.00. The contract is expected to last up to four and a half years and cost $41,379,583.30.
Water residuals are the byproduct of treating raw water to create safe drinking water. Residuals are created when chemicals react with suspended solids in the raw water. Under the National Pollutant Discharge Elimination System (NPDES) of the Clean Water Act, the entity that creates the residuals is responsible for safely and responsibly storing and disposing them. At PAWP, these residuals are stored in lagoons until disposal is needed. Periodically, approximately every 12 to 15 years, Lagoon 3 nears its residual storage capacity and must be emptied both to continue as a residuals storage facility and to prevent a discharge of these materials back into the environment.
The purpose of the PAWP Residuals Removal and Disposal - Lagoon 3 project is to provide services to remove, transport, and dispose of the water treatment residuals and grit-laden material from Lagoon 3. Some of these materials will be disposed of in a beneficial reuse manner as fertilizer or compost, while some of the materials will be taken to landfills for disposal. This disposal preserves the existing lagoon to continue to be used for residual storage. The cost of emptying Lagoon 3 of residuals is much less than it would cost to buy new land and build another residuals storage lagoon.
The Community Planning Area is 99 - Citywide.
