<p>Horner &amp; Shifrin, Inc., is designing improvements to Ste. Genevieve's wastewater treatment plant that will make it easier to treat wastewater during high-water events, and will extend the plant's useful life.</p>
<p>During wet weather conditions, the wastewater treatment plant flows are five to six times greater than during dry weather conditions, making it difficult to properly treat the wastewater. A new 450,000-gallon-capacity reinforced concrete flow equalization tank, which will employ a high-pressure water-cannon tank cleaning system, will allow the treatment plant operators to divert a significant amount of the flow to the tank during wet weather conditions. After wet weather conditions subside, the wastewater stored in the flow equalization tank will be pumped at a lower rate into the plant for treatment. The installation of new submersible pumps at Lift Station No. 1 will allow the operator to better control the rate of flow from the lift station into the treatment plant.</p>
<p>According to John Lauth, Horner &amp; Shifrin's project manager, "Our primary goals involve maintaining operations of the existing Lift Station No. 1 and the wastewater treatment plant while the improvements are being constructed, and optimizing the new facilities to provide cost-effective equipment and construction to fit the City's project budget. The updated facilities are being designed to meet current codes and Missouri Department of Natural Resources requirements."</p>
