Q. How much does it cost to treat
stormwater vs. sanitary sewage?
A. There is no cost to treat stormwater at the pipe outlet,
as this water is collected by a separate storm sewer pipe system, which
ultimately discharged to the Huron River without an end-of-pipe treatment.
Treatment and management of stormwater is handled through other mechanisms such
as source control, street sweeping, public education programs and stormwater
collection system maintenance. Stormwater does not make its way to the
wastewater treatment plan, unless it enters the sanitary sewer system through
defects, in the sanitary sewer system or private property sources like footing
drains. The cost for treating sewage at the wastewater treatment plant is
approximately $1400 per million gallons. Therefore, when any stormwater enters
into the sanitary sewer system, unnecessary cost is incurred because all the
flow which enters into the sanitary sewer pipes goes to the wastewater
treatment plant.
