Sewer Maintenance Warren Michigan

October 1, 2014

My neighborhood was built in the late 1960’s
and the wastewater from those households
flowed towards Warrens WasteWater Treatment Plant.
How often are all the sewer pipes power jetted,
inspected for cracks, mis-alignments, corrosion, etc.?

The houses near the Ryan Road Bridge over the Red Run
do vibrate/shake/shudder/rattle when heavy trucks go by.
Warren City council is aware of this fact, as I’ve spoken
at the microphone, on camera, stating this fact, publicly.
Traffic volume on Ryan Road Bridge is 25,900 in a 24 hour period.
I assume traffic volume is higher at the Mound Bridge
as well as the Van Dyke Bridge over the Red Run.
If nearby houses are rattled by traffic, so are the underground
drainage pipes, connections, fittings, joints, manholes, etc.

Rainwater infiltration into the sewage drains causes big problems
as the pipes simply can’t handle excess , added, unnecessary flow.
One pipe system exist strictly for rainwater via steel grates on the streets,
and a separate drain system exist for toilets, bath water, laundry, etc.

Distance to WasteWater Treatment

Distance to WasteWater Treatment

Most of the distance involved in gravity sewage transport from the
far NorthWest subdivisions involves 18 inch drainage pipe.
Gravity provides the transport power, using a downward slope.
All 17,300 feet involves gravity, NO pumps, to aid the flow.

As Warren is relatively flat, and drainage pipe slope was kept to a minimum,
perhaps semi-annual flushing and jetting would allow better capacity handling ?
Warren doesn’t use a lot of pumping lift stations to aid sewer transport.

    City of Warren uses online bidding site MITN for contracts of procurement. A search of closed bids for ” sewer ” shows three different vendors over three years on an on call as needed basis for cleaning / heavy cleaning for the 7 diameter ranges. Each contract included the vendor use video cameras in jetting the sewer system.
