This document outlines a federal contract opportunity for maintenance work at two water treatment plant clearwells. The solicitation is for upgrades and improvements to the 15 million gallon and 30 million gallon clearwells and their connecting conduits at the Dalecarlia Water Treatment Plant. Work includes upgrades to drain lines to eliminate potential cross connections, rehabilitation and replacement of large sluice gates, installation of new flow meters and induction mixers, improvements to the clearwell overflow structure, rerouting of chemical analyzer drain pipes, and soil drainage improvements. Additional mold remediation and HVAC upgrades are required in a building near the 15 million gallon clearwell. Outages for work must be coordinated with lower seasonal demand periods and sequenced so only one clearwell is out of service at a time. The solicitation was issued by the Department of the Army Corps of Engineers Baltimore District for these critical water supply infrastructure upgrades.
