The Milwaukee Water Works Capital Improvements Program provides for long term improvements to utility infrastructure to ensure a reliable supply of high quality drinking water. The capital budget is based on long-term planning to replace or upgrade existing infrastructure, and to install new infrastructure as needed. The Capital Improvements Program prioritizes projects based on results of water-related research, new technology, and condition assessments of existing systems. The program includes treatment processes, buildings, laboratories, pumping and water storage, equipment, water mains, and hydrants. A multi-year project to provide backup electric power generation for five critical infrastructure sites is underway with design and installation of diesel generators to power treatment processes and pumps in the event of an electrical outage. Production facilities were completely renovated in the 1990s. Since 1993, the Milwaukee Water Works has invested $406 million in its infrastructure, as reported to the Public Service Commission of Wisconsin.
The MWW repairs and maintains 1,960 miles of water mains in the distribution system throughout the City of Milwaukee and the retail customer suburbs of Greenfield, St. Francis, and Hales Corners to ensure continuous delivery of sufficient high quality water. Scheduled activities include repair and maintenance of facilities within every upcoming paving project area, inspection of 20,000 hydrants, flushing of dead end water mains, and leak surveys to identify non-surfacing water leaks.
