Site work for a water / sewer project in Macon, Missouri. Completed plans call for site work for a water pump station.

The retrofit of a lift station located at 1402 S. Missouri Street, Macon, Missouri. The purpose of this project is to upgrade lift station to meet reliability, maintenance, and safety standards. Installation must be according to Missouri Department of Natural Resources Minimum Design Standard 10 CSR 20-8.130. The existing wet well is a concrete cylindrical structure approximately 18 feet deep and 4 feet in diameter. The wet well is covered by a concrete top with a manhole lid that is offset from center. The 3-inch force main exits the wet well approximately 11 feet from the finished floor of the wet well. The two (2) existing pumps are older 1 horsepower Liberty grinder pumps. These pumps utilize an older retrieval method that requires the service technician to enter the wet well and pull the entire pump and piping assembly above ground. The control panel is mounted above ground on a wood rack next to the meter and the service entry disconnect. The primary service is 240v/ 1 phase. The control panel enclosure is made of FRP and due to the UV has deteriorated. This station utilizes floats to control the lift station on and off sequence. The scope of this project consists of removing the existing wet well cover, pumps, internal piping and control system. Installation of new pumps with base elbows, guide rail system with stainless steel lift chains, internal piping complete with check valves and bypass connection, new junction box and FRP control panel, complete with controls, light/audible alarm, 5 float system with high/low level alarms and new wet well cover with an aluminum/stainless steel access hatch to allow for adequate accessibility. New pumps should be capable of handling 30 gallons per minute at the calculated head conditions and grinder style pump due to the 3-inch force main.
