Lake Saint Louis Sewer Improvement Program
The Lake Saint Louis Sewer Improvement Program is a capital improvement project aimed at evaluating, upgrading, and/or relocating approximately eight miles of sanitary sewer mains currently buried beneath Lake St. Louis and Lake St. Louise. The District’s contractor is currently installing five access manholes within Lake St. Louis, cleaning and inspecting all mains, and was recently awarded a contract change order to install three additional manholes within Lake St. Louise for future maintenance and emergency bypassing considerations. Work on the large lake is expected to be completed by the end of 2017. Work on the small lake has been extended to Spring 2018.
Henke Lift Station Force Main Upgrades, Phase 1
The Henke Lift Station currently pumps into a 16-inch ductile iron force main that runs along Lake Saint Louis Boulevard and up Charlemagne Drive to the O’Fallon Hills Subdivision, where it deposits into City of O’Fallon gravity sewers. In order to increase the pumping capacity of the station, the District is planning upgrades to the main. Phase 1 of the project will upgrade the force main to 24-inch from just south of Charlemagne to new O’Fallon gravity sewer to be built north of Highway 70. Phase 2 will upgrade the remainder of the force main. Phase 1 is scheduled to begin construction in late 2017.
Lakewood Lift Station
The existing Lakewood Lift Station at Lakewood Park is an emergency lift station that operates only during high flows. Even with the station operating, some area manholes still experience overflows in times of exceedingly high flow. Construction of a new collector station will take flow away from the under-lake sewer system where the existing lines are below capacity and should alleviate the current overflow problems.
Stump Road Water Main Replacement
The District has bid the replacement of an existing 10-inch water main along Stump Road with a new 16-inch main. The new 16-inch main will allow for more flow to be conveyed north to the O’Fallon service area. Construction of the new main is nearing completion. Final restoration is to occur this summer.
Hwy N Water Main Replacement (Phase 1)
In accordance with the District’s Master Plan, the existing 16″ water main along Highway N will be upgraded to a new 24″ main west to Duello Road. Phase 1 of the project will replace the 16″ main from Welsh Drive to the District’s Highway N Booster Pump Station west of Stag Industrial Boulevard.
Augusta WWTP Relocation
In order to meet more stringent discharge limits soon to be required by Missouri Department of Natural Resources, the Augusta Lagoon requires upgrades. As part of the project, the District will be relocating an existing package wastewater plant from the Hickory Trails system in Wright City to the Augusta site. Relocation is scheduled to begin in the summer of 2017.
Water Treatment Plant Surge Pump Replacement
The existing Water Treatment Plant Surge Pumps at the District’s Treatment Plant in Defiance, MO provide water pressure at the plant necessary to perform essential plant treatment operations. As part of this project, the pumps and their controls will be replaced. Additionally, the concrete floor of the treatment plant basement will be epoxy coated. Construction of this project is scheduled for the summer of 2017.
