City of Mequon - Building Sewer Lateral Work
The City of Mequon is hosting a Public Information Meeting for the proposed Building Sewer Lateral rehabilitation work in Ranch Road Lift Station E area.
In the summer-fall of 2023, the City of Mequon is planning to construct a parallel sanitary force main in County Line Road from Tamerlane Drive to Granville Road. Vehicular Detours are anticipated to allow work shaft construction. Traffic detours are planned to route vehicles along from Swan Road to Donges Bay Road and to Granville Rd. This work includes approximately 2400 linear feet of 8-inch dia. sanitary force. The construction is anticipated to take 45 working days and be completed by December 22, 2023. Sewer service will not be interrupted.

In response to flooding that resulted from the June 2014 and April 2015 wet weather events that caused numerous basement back-ups, the Sewer Utility District commissioned a study for a wet weather relief sewer. In 2016 the Common Council approved this study, design was completed in 2017, sewer work began in 2018 and construction was completed ahead of schedule in 2019 south of Mequon Road. The impacted project areas were restored in 2020.
As part of the Mequon Water Utility Capital Program Budget and in coordination with the Village of Thiensville, a water main extension in Buntrock Avenue was completed from the Seminary Drive past North Orchard Street to Main Street in Thiensville. This water main extension connects and loops two “dead end systems” and improves water circulation in the overall system, and is considered a betterment of services project as categorized by the Public Service Commission of Wisconsin.
The schedule for the Buntrock Watermain extension:
As part of the Mequon Sewer Utility Capital Program Budget and in coordination with the Village of Thiensville, a third phase to rehabilitate the Mequon-Thiensville Sanitary is planned to begin in spring 2021 in Cedarburg Road. This sanitary sewer rehabilitation in Cedarburg Road extends from County Line Road to Donges Bay Road. This rehabilitation work includes the installation of a cured-in-place-pipe lining system that extends the life of the pipe and limits major excavation. The current project is scheduled to be completed in the summer of 2021, in advance of the road work on Cedarburg Road (STH 57, State of Wisconsin Department of Transportation project). The first phase of work was completed in 2017, and the second phase was completed in 2020. The third phase of the sewer work is anticipated to begin in spring 2021 and be completed in summer 2021.

As part of the Wisconsin Department of Transportation I-43 reconstruction project, the Mequon Water Utility is relocating water main along Port Washington Road to avoid impacts of a new sound wall and also at Highland Road for a new bridge with on/off ramps. This utility work is anticipated to be completed prior to the DOT roadwork project. The water main relocation work near County Line Rd and Highland Rd is scheduled to begin in Fall 2021 and be completed prior to February 2022.

Highland Rd Project
In July 2020, the Sewer Utility District Commission and Common Council authorized installation of a back-up generator for the City’s sanitary lift station pump. This lift station is located along Parkview Drive in the Mequon Country Estates Subdivision near Homestead Highschool. This lift station was originally installed without a generator. A generator is an essential back-up power supply to maintain operation for the Mequon Country Estates sewer service area.
In the summer of 2021, the City of Mequon is planning to replace the sanitary force main in County Line Road from Reibs Road to Arrowood Drive. Vehicular Detours are planned after the 4th of July as the road will be closed to through traffic at the Wisconsin Central Ltd. (CN) Railroad crossing. Traffic detours are planned to route vehicles along STH 57 / STH 167 / STH 181. This work includes approximately 1400 linear feet of 6-inch dia. sanitary force. The construction is anticipated to take 45 working days, and sewer service will not be interrupted.
Wet weather events, such as intense rainfall and/or snowmelts, often cause supersaturated soil conditions which can be attributed to inflow and infiltration of clear water in sanitary sewer collection systems. While the sanitary sewer collection system is designed to accommodate an amount of clear water flow, when the amount of inflow and infiltration exceed the design capacity of the system, then bypassing occurs.
Routine inspection of the sanitary system pipes in the Riverland Drive and Riverdale Park areas revealed numerous joints with infiltration, where groundwater is entering into to the sanitary sewer system. This project will test and grout nearly four miles of pipe joints to prevent further infiltration from occurring. This helps preserve the integrity of the collection system and future use.
