An
EDU or “Equivalent Dwelling Unit” is a unit of measure of the volume of
expected wastewater flow generated by the average single family residence. The EDU is determined by the Authority’s
engineer using the factors authorized by the Municipality Authorities Act to
calculate the annual flows treated at the sewer plant. Use of EDU’s enables the Authority to charge
uniform rates to its customers.
Residential: In Evans City
1 EDU is equal to 5400 gallons. This
means that the average single family residence in Evans City generates
approximately 5400 gallons of wastewater monthly. The cost of treating this monthly wastewater
flow is one of the components that comprises the monthly sewage bill for each
customer.
Industrial
and Commercial: Industrial and commercial customers are also
charged by EDU’s. However, the number of
EDU’s they are charged varies based on the previous year’s wastewater flows generated
by each industrial and commercial customer.
We
hope this helps you understand your monthly bill.
