Body
PREAMBLE
The Madison Metropolitan Sewerage District (MMSD) Pump Station 10 Forcemain project intends to rehabilitate approximately 2,000 linear feet of 36-inch diameter sanitary sewer located in the Wisconsin Southern Railroad corridor between Buckeye Road and Cottage Grove Road on Madison’s East Side. In order to maintain continued operations of the sewer line, MMSD will need to install temporary bypass piping which allows for continued flow of wastewater through temporary piping while rehabilitating the existing line; this work does not allow for all construction activities of the project to take place during the normal working hours of 7:00AM and 7:00PM. Construction activities will commence between October 2018 and May 2019 and will take approximately 6 weeks to complete. The construction work is anticipated to extend into the evening hours for 2 nights when the installation of the pipe is underway but if there are unplanned construction delays, additional nights may be required.
Madison General Ordinance section 24.08(3) provides the Common Council the ability to allow construction activities outside of the hours of 7:00 AM to 7:00 PM with the passage of a resolution and a hearing before the Board of Public Works. It is anticipated that the Contractor performing this work will call for permission to perform the work required to continue pumping operations outside the hours of 7:00 AM to 7:00 PM because:
1. The bypassing and installation processes may operate outside of the standard working hours
The proposed activities beyond the hours of 7:00 AM to 7:00 PM may be as follows:
1. Hydraulic cleaning of the sanitary sewer main sections to be lined to remove any accumulated debris prior to lining;
2. Use of temporary piping to bypass wastewater;
3. Installation of new pipe in existing forcemain;
4. Conducting a closed-circuit inspection of the lined sections of sanitary sewer mains to provide documentation to the district that all required work has been satisfactorily performed.
NOW THEREFORE BE IT RESOLVED, that construction work, with associated noise impacts, between the hours of 7:00 PM and 7:00 AM on are hereby approved in accordance with Section 24.08(3) of the Madison General Ordinances., and
BE IT FURTHER RESOLVED, that the construction activities outside the hours of 7:00 AM and 7:00 PM are limited to those activities identified in this resolution and the hours specified, and
BE IT FURTHER RESOLVED, that the approval of that construction work, as provided in this resolution shall expire on July 1, 2019.
