LEAGUE CITY - As part of League City’s Capital Improvement Program, an engineering evaluation of the City's sanitary sewer systems is performed annually, and a strategic rehabilitation plan of these systems is identified and prioritized. The scope of this year’s project will replace an existing discharge brick manhole and approximately 310 linear feet of an existing 10-inch Asbestos Concrete (AC) force main along SH3, between the discharge manhole and the existing lift station site at the intersection of SH3 and SH 96. A visual assessment of the existing lift station and wet well revealed deteriorated conditions warranting structural rehabilitation on both structures to prolong the life of infrastructure. The design will include coating the interior of the wet well, replacing all existing piping, suction, and discharge equipment, and installing new submersible pumps and controls. All existing piping is currently located inside the dry well section of the lift station. All new piping will be located above ground, thus eliminating confined space entry. New stainless-steel electrical panels, including a generator plug-in connection, will be included in the lift station upgrades. The design consultant provided the proposed force main layout depicted below. The proposed force main has shifted to the south approximately six feet, providing a cleaner alignment. A meeting has been scheduled for October 18 to discuss design progress. Thirty percent plan submittals are anticipated to be submitted by the end of October. Design of the lift station and force main replacement will take approximately 5 months to complete with construction anticipated to bid March 2022.
