01 May Backflow prevention testing resumes with spring watering
As irrigation systems come back online, so too will return WHUD’s annual backflow testing program. Backflow prevention is required by the state of Tennessee to keep public water supplies safe and free of unwanted water or other products, like runoff or chemicals used during irrigation. Backflows can take place at any unprotected cross connection in the distribution system or if something happens to cause the water to flow in reverse, like a sudden change in pressure.
Homeowners with piped irrigation systems, commercial water lines, and residential and commercial fire lines are required to have backflow prevention methods or devices. While home- or business-owners are responsible for installing, operating and maintaining backflow prevention methods and devices, the Tennessee Department of Environment and Conservation (TDEC) requires utility providers, like WHUD, to test these each year.
During peak summer months, WHUD tests up to 1,200 devices in a month. The test requires the water to be turned off temporarily. Because of this, there are a couple of ways residents and local business owners can ensure a quick and easy inspection:
- Notify WHUD if you do not plan to run your irrigation system by calling 615-672-4110, ext. 457.
- Be prepared for our visit. WHUD will notify residents of a general time frame in which their device will be tested. Residents can help by making sure the device is connected, with no apparent leaks, and is easily accessible.
Like irrigation systems, backflow preventers need to be maintained each year, in addition to being inspected by WHUD. The best way to ensure your backflow prevention device is properly maintained is to contact a plumber or irrigation professional for assistance.
