Understanding Your Bill


A four-year ALCOSAN rate structure was approved by the Board of Directors at its public meeting on October 24, 2013. This rate structure is designed to enable ratepayers and our municipal customers to strategically plan for future expenses

ALCOSAN rates as of January 1, 2016 are as follows:

  • $6.23 per 1,000 gallons of water used ($0.62 increase over 2015 rates)

  • $13.07 quarterly customer service charge per bill ($1.29 increase over 2015 rates)

An average customer who uses 13,000 gallons of water per quarter will pay an additional $9.33 per quarter, or $3.11 per month.

How bills are calculated
ALCOSAN's charges are based on the amount of water a customer uses during a quarterly billing period. Water usage information, whether usage is based on meter readings or a flat rate, is provided by the water company.

Because your sewage bill is based upon water usage, your bill may vary each quarter. Factors which impact both your water and wastewater bills are:

  • Seasonal Conditions
  • Changes in the number of occupants in your home
  • Water conservation

Of the 83 communities in our service area, only three are billed directly by ALCOSAN.  In all other communities, bills are sent to your municipality who pays the charge on behalf of the ALCOSAN customers in that municipality.  The municipality then bills each customer the ALCOSAN charge along with any additional municipal surcharges.  ALCOSAN has no jurisdiction in setting, collecting or monitoring municipal sewage charges.  In addition, the municipality, not ALCOSAN, has the jurisdiction to shut off water service due to non-payment of wastewater charges.

Bill Payments

  1. Payments by direct bill customers may be mailed or be made in person at ALCOSAN’s Customer Service & Billing Department from 9:00 a.m. to 4:00 p.m. Monday through Friday. ALCOSAN is located on Pittsburgh's Northside. Call 412-766-6696 for directions.
  2. If you are billed by your municipality, please contact your municipality regarding payment procedures.

Late Payments
Sewage bills issued by ALCOSAN and not paid by the due date will be subject to penalties as follows:

  • After the due date, a late charge of 5 percent is applied to the original amount due.
  • Bills more than 60 days late are turned over to your municipality for collection.

Commercial/Industrial Accounts
Sewage charges are increased by a factor for those customers whose wastes have an unusually high concentration of suspended solids and/or biochemical oxygen demand and/or chlorine demand.

For more information about high-strength discharge surcharges, please contact the ALCOSAN Industrial Waste Department.

The Difference Between ALCOSAN, the Water Company and the Pittsburgh Water and Sewer Authority
Your water company and ALCOSAN are two distinctly separate companies, each with its own functions and responsibilities. Your water company is responsible for the treatment, delivery and billing of drinking water. ALCOSAN is responsible for the treatment, disposal and billing of wastewater.

ALCOSAN and the Pittsburgh Water & Sewer Authority are two different agencies with separate functions.

The Pittsburgh Water and Sewer Authority is responsible for producing and supplying the water for City of Pittsburgh residents and maintaining the entire City of Pittsburgh sewer system.

If a correction is made to your water bill which involves a change in consumption, the water company forwards it to ALCOSAN and you will receive a corrected sewage bill.

If you believe ALCOSAN has made a billing error, please call or write immediately. This procedure also applies to name and/or address changes.

When writing, include your account number, amount and reason for dispute. When calling, please have this information on hand. A representative will be happy to assist you with any questions.
