Most ratepayers do not receive a bill directly from ALCOSAN. That only occurs in three communities - Aspinwall, Ben Avon and Thornburg are the only existing customers directly billed by ALCOSAN.  In the other 80 municipalities that ALCOSAN serves, ALCOSAN bills the municipality and that fee is then passed on to the homeowners in a utility bill from another agency.  For those communities, visit our Municipal Customers page for more details.

About Direct Bill Customers

While there are only three direct bill communities in our service area, ALCOSAN’s service and charges for that service remains consistent for all customers.

Understanding Your Bill

How to Pay Your Bill

ALCOSAN has suspended any in-person customer service or payments until further notice. If you have customer service or billing questions, please call 412-766-6696.

Direct Bill Customers may pay their bills by mail or in person Monday through Friday, 9 a.m. to 4 p.m. at the ALCOSAN Customer Service and Billing Department at 3101 Preble Avenue, Pittsburgh, PA 15233. Sewage bills issued directly by ALCOSAN are subject to a 5 percent late fee after the due date and are turned over to your municipality for collection after 60 days.

Bill Pay Assistance

If you need help paying your water bill, ALCOSAN’s Clean Water Assistance Fund is available for eligible homeowners. ALCOSAN has committed nearly a million dollars in order to provide this vital customer assistance program for low-income individuals and families.


Direct bill customers can submit questions, as well as name and/or address changes, to ALCOSAN’s Customer Service and Billing representatives at 412-766-6696, or using the link below.  Please be sure to include your account number.
