CHAPTER 4
UTILITIES PLAN
■ TODAY’S CONDITIONS
As has been seen throughout the County’s history, the quality and adequacy of utility infrastructure can help or hinder growth.
WATER SUPPLY
In Allegheny County, water supplies for drinking water are obtained primarily from surface water sources; only 10% comes from groundwater. Water suppliers in the County use the Three Rivers as water sources, as well as the Youghiogheny River, Indian Creek and Beaver Run in Westmoreland County. As per the Pennsylvania Municipalities Planning Code Article III Section 301(b), Allegheny Places strives to be consistent with the State Water Plan and any applicable water resources plan adopted by any river basin commissions. Allegheny Places also recognizes that:
- Lawful activities such as extraction of minerals impact water supply sources and such activities are governed by statutes regulating mineral extraction that specify replacement and restoration of water supplies affected by such activities.

- Commercial agriculture production may impact water supply sources.
PUBLIC WATER
Allegheny County prepared its Comprehensive Water Supply Plan in 1996. The plan inventories public water suppliers active in the County along with the technical and financial details of each. The inventory was supplemented for Allegheny Places by mapping service areas and collecting recent water demand and capacity data.
Public water service is provided to approximately 97% of County residents by 41 public water suppliers, as listed in Table 4J.1. Twenty-two of the water suppliers are municipal authorities, 18 are municipalities, and one is an investor-owned utility. Private wells provide water in areas that are not served by public water systems. Currently, all of the water suppliers are operating within established water allocations.
The water suppliers currently distribute approximately 270 million gallons of water per day (mgd) to approximately 620,000 residential, commercial, industrial, institutional and bulk sales customers in the County.
Twenty of the water suppliers are considered primary water suppliers since they operate both sources of supply and treatment facilities. They supply water directly to their customers and to other public water systems for distribution and sale.
The approximate service areas of these systems within Allegheny County are illustrated on Map 4J.1.
In general, the water distribution systems operating within Allegheny County function acceptably under current demand conditions. No significant areas of chronically unacceptable low flow and pressure conditions have been identified.
A total of 23 water treatment facilities are currently being operated by the water suppliers serving Allegheny County. The total rated capacity of the treatment facilities is 457 mgd. Total treatment capacity well exceeds current average day and maximum day water demands. The total treatment capacity represents approximately 131% of the current maximum day water demand.
