Storm water overflow


...continued from page 6

In Oakland County, a more common way of addressing CSOs has been to build additional treatment or storage basins to contain a portion of the volume and provide treatment of any resulting discharge. Specifically, as part of the final corrective program, many owners of combined sewer systems have installed or are installing Retention Basin Treatment facilities.

Currently, the Oakland County Water Resources Commissioner's Office is working on a $46 million project that would add 3.7 million gallons of retention capacity to the Evergreen-Farmington sewer system. The project will consist of a 7,600 foot tunnel, 9-feet in diameter, to provide additional sewage capacity for the existing Farmington gravity sewer interceptor, located on Middlebelt Road between 13 Mile Road and I-696. The tunnel will vary in depth from 40 to 80-feet below the surface of Middlebelt Road.

One of the actions the DEQ has taken to address overflow problems is through the the state's Stormwater Asset Management and Wastewater (SAW) program, which helps municipalities plan for sewer system maintenance. The program provides grant assistance for developing storm water and wastewater project planning and design, asset management plans for wastewater and storm water systems, storm water management planning and testing, and demonstration of technology.

In October, the MDEQ awarded about $91 million to municipalities throughout the state through the program. The grant awards are the second round of SAW grants, with a total of 207 municipalities across the state receiving grants, totaling about $170 million, including a $1 million grant to Commerce Township.

Commerce will receive funds through January 2017 from the program, with the township matching $109,944 of the total amount. The funds will go to develop an asset management plan for the wastewater collection and treatment system, design and engineering costs related to the abandonment of the Welch Road, Haggerty Road and Commerce Towne Center Pump Stations. The grant will also help to fund the development of a sanitary sewer asset management plan.

Nigro said asset management and plans created through the SAW program will help to identify issues before they become problems.

"I like to think that, as far as asset management, we are already ahead of the curve," he said.
