Elevation and basements

March 31, 2014

People often “forget” or simply don’t think much
of the pipes flowing in/out of their basements.
Do you happen to know the elevation of your driveway,
your patio, or the slab of concrete in your basement ?
Even Lake Erie is 571 feet above sea level.
Most of Warren,MI is around 620, 630 ft above sea level.
Water must be made to flow ~ somewhere ~ otherwise
it merely pools, puddles, collects wherever it can.

METCO studied the underground drainage piping in Warren.
The City of Warren is basically flat, somewhere around 620 ft elevation
The underground piping is approximately in the 600 to 610 ft range.
Keep in mind 1 mile = 5,280 ft and the water has to flow 1,000’s of feet.
Start at Zero 0 – 5,280 ft – 10,560 ft – 15,840 ft – 21,120 ft
Sewage Water has to flow via gravity , or otherwise
be pumped for miles, to be treated at a facility.
