Safeguarding our public water system is an essential part of our mission to protect public health. 

 Each connection on our system, residential homes and commercial businesses, present an opportunity for contaminated water to enter our water system.  Without the use of backflow preventers, water from private systems, such as industrial plants, and medical facilities, could enter our system, and impact the water quality.

 To protect our system, DPU has a backflow prevention program that is strictly monitored and enforced. 

 

 What is backflow?

Backflow is the reversed flow of non-potable water or other substances into the public water system.  It is caused by a drop in pressure in the public water system.

 Who is required to have a Backflow Preventing Device?

Since backflow hazards are determined by the type of business, and how water is used, we evaluate each account on an individual basis.  The types of accounts that require a backflow preventer are:

  • Restaurants
  • Dry Cleaners
  • Medical Offices
  • Funeral Homes
  • Beauty and Nail Salons
  • Car Washes
  • Multi-tenant Retail Space
  • Commercial Buildings 3 stories or taller
  • Commercial Space with a Dedicated Fire Service Line/Sprinkler System
  • Churches with Baptismal Pools
  • Irrigation systems
