The MAWC is required to implement and enforce a backflow prevention program in accordance with Pennsylvania’s Safe Drinking Water Act. Specifically, 25 PA Code Chapter 109 mandates that:
No person may introduce contaminants into a public water supply through a service connection of a public water system.
- It shall be the responsibility of the customer to eliminate cross connection or provide backflow devices to prevent contamination of the distribution system from both backsiphonage and backpressure. Individual backflow preventers shall be acceptable to the public water supplier.
- If the customer fails to comply with paragraph (1) within a reasonable period of time, the water supplier shall discontinue service after reasonable notice has been made to the customer.
This regulation applies to all customer types including industrial, commercial and residential users. Over the past several years, the MAWC has made significant progress towards ensuring that all industrial and commercial customers within its service area installed and continue to maintain backflow prevention devices. Maintaining a safe drinking water supply is everyone’s responsibility.
MAWC recently partnered with VEPO CrossConnex to help us convert to a more efficient management program. All tests and test data must be submitted by your tester using VEPO CrossConnex software. Testing must be performed by a certified backflow prevention tester pursuant to Pennsylvania Department of Environmental Protection regulations, Part VIII of document number 383-3100-111.

Your certified tester can download the free mobile application from the Apple Ap Store for Apple Mobile Devices or Google Play for Android, or use Any PC to access the VEPO web portal at https://www.veposolutions.com/vepo-crossconnex. Please notify your tester of your VEPOCrossConnex (VCC) code which you should receive in the mail from VEPO. The code starts with the letters MAWC and is followed by your water account number. For example, MAWCXXXXXXXXX. The tester will need this VCC code in order to submit your test with the VEPO CrossConnex software.
If your tester needs help setting up their profile with VEPO CrossConnex after downloading the application, or have any technical questions regarding the software, please call VEPOCrossConnex at 877-860-8376 for assistance.
RESIDENTIAL CUSTOMERS: Installation of a dual check valve for backflow prevention is required by the Safe Drinking Water Act. This will create a closed system within your home and may require the installation of an overflow tank on your hot water tank, or the installation of a thermal expansion relief valve. Please consider this when you are preparing your plumbing for municipal water.
All assemblies and/or devices should be horizontal. Other positions as approved by the Water Authority. Follow Authority guidelines for location of backflow preventer and any valving required.

General Information -- Definitions
- Backflow - A hydraulic condition caused by a difference in pressures, in which nonpotable water or fluid flow into a potable water system.
- Backpressure - A condition in which a pump, boiler, or other equipment produces a pressure greater than the water supply pressure.
- Backsiphonage - A condition in which the pressure in the distribution system is less than atmospheric pressure, which allows contamination to enter a water system through cross connection.
- Cross Connection - Any arrangement of pipes, fittings, fixtures, or devices that connects a nonpotable system to a potable water system.
- Potable - Relating to water that does not contain objectionable pollution, contamination, minerals, or infective agents and is considered satisfactory for domestic consumption.
