Non-Sewered Water Credit
Savings Example
Total water purchased from the water
agency:
1000 CcF/year*
Water evaporated in cooling tower:
100 CcF/year
Water used in irrigation:
50 CcF/year
Total non-sewered water:
100 CcF/yr + 50 CcF/yr = 150 CcF/yr
Total sewered water:
1,000 CcF/yr -150 CcF/yr = 850 CcF/year
Volume charge on sewer bill before non-
sewerd water credit:
1,000 CcF/yr X $3.97/CcF** = $3,970.00/year
Volume charge on sewer bill after non-
sewered water credit:
850 CcF/yr X $3.97/CcF** = $3,374.50/year
Savings from non-sewered water credit:
$3,970.00/yr – $3,374.50/yr = $595.50/year
* A Ccf is a unit for measuring water. One Ccf is
equal to 100 cubic feet of water or about 750
gallons.
** $3.97/CcF was the MSD volume charge as of
July 1, 2017. This rate may change in the future.
There also are other charges on your sewer bill.
Who We Are
The Metropolitan St. Louis Sewer District’s
(MSD) mission is to responsibly provide sewer
service and stormwater management to protect
the public’s health and safety.
Established by a vote of the citizens of the City
of St. Louis and St. Louis County in 1954, MSD
today serves a population of approximately 1.4
million. MSD is responsible for one of the
largest and most complex sewer systems in
the United States, represented by the
maintenance and operations activities we
perform on over 9,600 miles of sewer lines.
MSD wastewater treatment facilities process
an average of 330 million gallons of
wastewater everyday.
At MSD, we work closely with the communities
we serve and prioritize our resources to make
the greatest impact for our customers in the
shortest time possible. With a clear focus on
customer service, we establish priorities and
deliver effective performance.

Purpose
Sewer bills are calculated based on a facility's
consumption, or the amount of water the
facility purchases from the water supplier.
Industrial and commercial customers may
apply for a reduction in wastewater service
charges when some of the water they use
does not enter the sewer system. The volume
of water not entering the sewer must be
measured and documented to receive the
credit. The amount of purchased water that is
discharged to MSD, when expressed as a
percentage of the total consumption, is called a
return factor. The return factor is applied to the
water consumption volume on MSD's sewer
bills to calculate the volume charge for the
amount of water discharged to MSD. Return
factor reviews are administered by the MSD
Division of Environmental Compliance (DEC).
Water not entering the sewer is described in
the MSD user rate Ordinance available on
MSD’s web site located at www.stlmsd.com.
Typical Non-Sewered Sources
Generally, most sources of non-sewered water
are described by one of the following
categories:
Water-in-Product
Cooling Tower Evaporation
Irrigation
How to Apply
Download an application from www.stlmsd.com,
under the What We Do > Industrial Customers
menu, and email it directly to MSD at
rfquest@stlmsd.com. Or call the MSD Finance
Department at (314) 768-6200 and ask for an
Application for Reduction of Sewer Charges for
Non-Sewered Water. Then complete, sign, and
mail the application back to MSD.
Requirements
When DEC receives a completed and signed
Application for Reduction of Sewer Charges for
Non-Sewered Water, DEC contacts the
customer to set up a meeting and review non-
sewered sources. Customers then meter the
non-sewered water for one year and document
the meter readings on forms provided by DEC.
Meters must be installed at the customer’s
expense. For example,
make-up and blowdown
meters can be used to
determine cooling tower
evaporation. One meter can
be used to meter an irrigation
area. Production records
can be used to determine water-in-product. A
return factor is applied to the customer’s future
sewer bills after MSD receives a signed
application and when the documentation of
non-sewered sources is complete.
Update Reviews
DEC performs periodic reviews of existing
return factor customers. In addition, customers
may re-apply for additional credit for new and
existing non-sewered sources at any time by
calling our Finance Department and submitting
a new application.
Questions
If you have specific questions about the MSD
Return Factor program before you apply and
wish to speak to someone within DEC, please
call (314) 436-8710.
Additional Savings
As a good steward of the environment, MSD
wants to notify customers that the best way to
lower your sewer bills and help the
environment at the same time is by practicing
water conservation. Low usage plumbing
fixtures and recycling can help achieve this.
More information about water conservation can
be found by contacting the following
organizations: American Water Works
Association http://www.awwa.org, and the
