2010 Stormwater Management Report (PDF) - US Environmental ...

The Commission estimates the wastewater removed by elimination of an illegal
connection based upon water use records for the property where the illegal connection
was corrected. Average daily water consumption is calculated based on the previous 24
month period, and 90 percent of the water use is assumed to discharge to the sewer
system. If only a portion of the building contributed to the illegal connection, the figure
is adjusted accordingly.
Due to the Commission’s efforts in 2010, an estimated 8,632 gallons per day (gpd) of
wastewater was removed from the storm drainage system and receiving waters. Of this
amount, approximately 3,935 gpd was from residential and multi-family properties, while
4,697 gpd was from businesses or institutions. Between 1986 and the end of 2010, an
estimated total of 575,849 gallons of wastewater per day have been removed from the
storm drainage system and receiving waters as a result of the Commission’s illegal
connection remediation programs.
In 2010, the Commission spent $189,936 to correct 18 illegal connections, for an average
cost of $10,552. This cost does not include the cost of permits, inspection fees, pavement
restoration or police details, and it does not include the cost to property owners who were
responsible for making corrections on their own property.
