The City of New Berlin, Wisconsin, was under a development moratorium that required the City to reduce inflow/infiltration sources in its collection system to allow for additional development. The City reached out to raSmith, who had a history of project work with New Berlin and experience in performing similar work for other local government clients.
The greatest project challenge was identifying sources of excess flow and developing a plan to bring them back into compliance. A comprehensive rehabilitation program was developed for the publicly owned portion of the collection system. raSmith had the engineering foresight and know-how to also recommend and implement improvements to the private property portion of the collection system to promote the long-term sustainability of the collection system as a whole.
The rehabilitation program yielded immediate benefits including the lifting of the moratorium to allow further development in the City and expansion of the tax and customer base, which provided the City and its utility with additional revenue. In the long term, operation and maintenance costs associated with the collection system will be reduced.
