This project will be installed during the summer of 2020 and will include the construction of approximately 9,000 L.F. of 20”-24” sanitary sewer trunk force main. The proposed route is from an existing connection point on South Commerce Road, then along the drain through Dodge Park #5 and along the west side of Newton Road to Oakley Park Road. The attached map shows the planned route of this sewer.
The primary reason that the Newton Road Force Main project has been a part of the capital improvement plan for the sanitary sewer system is to provide redundancy in the system. The force main will provide a redundant loop that will allow the WRC to bypass approximately four miles of existing force main in the event of a sanitary sewer break or when it needs to be repaired as part of regular maintenance.
The existing alternative for an emergency bypass is a pump and haul system. A pump and haul bypass of the existing force main would require up to 100 trips/day with 10,000-gallon tankers. Although a pump and haul bypass of this magnitude is possible, the logistics become difficult, especially in the event of an unplanned failure. The redundant loop created by the Newton Road Force Main project will greatly reduce the risk of a sanitary sewer overflow.
Part of the project also involves the installation of a parallel low-pressure sewer and structures from Oakley Park to Richardson that will give residents the option to extend sewer down their street through a Special Assessment District once the sewer is in service.
