DWSD Proposes to Overhaul Operations at WWTP to Address Permit Violations

In response to Violation Notices issued by the State of Michigan DNRE on November 12, 2009 and again on April 14, 2010,  the Detroit Water and Sewerage Department has submitted a 28 page Corrective Action Plan (CAP). 

The CAP outlines DWSD's plan to bring its waste water treatment plant (WWTP) back into compliance with the City's NPDES discharge permit. The permit violations, discharging high concentrations of sludge (TSS),  are primarily the result of the City's inability to dewater and dispose of sufficient quantities of biosolids (sludge). 

Earlier reports have identified multiple causes of this problem, including equipment failures, inadequate preventive maintenance, lack of spare parts, and limitations on off-site disposal. The Synagro contract, canceled  in January, 2009 under the cloud of scandal, was designed to alleviate some of these problems.
