BSU needs your help
During the past few years, upside-down U-shaped pipes have appeared in front yards all over Bonita Springs. They’re ugly, but they are a critical component in protecting our water supply and ensuring public safety.
Bonita Springs Utilities has installed nearly 25,000 of these backflow-prevention devices for our residential and commercial member-customers. They prevent possible contamination of our drinking water supply by blocking water from flowing backward through water mains. Without backflow prevention, contamination could occur during a loss in pressure in the water system when a water main breaks, a large fire is fought, or when another user taps into a private water line.
Thousands of cases of backflow contamination are reported in the U.S. each year, and many others go unreported. Although backflow devices are required by law, many utilities have moved slowly to install them or have charged their customers for the equipment and installation. BSU typically installed the devices without charge to our member-customers.
Why weren’t they installed underground? State law requires routine inspection and maintenance, so quick and easy access to the backflow-prevention devices is important. Most of the devices are designed to noticeably discharge water if check valves fail or if backflow conditions occur. If you notice water pouring from the equipment, please contact our office immediately, so a technician can repair or replace the backflow-prevention device.
We encourage homeowners to use landscaping to soften the devices’ visual impact, but to be sure to leave plenty of access space, so plants won’t hamper our periodic checks and maintenance. Please limit landscaping to three sides of the equipment, or only two sides, if it’s located close to a road or sidewalk.
Our technicians need enough room between the landscaping and the equipment to do their work. Thirty inches – two-and-a-half feet – is ideal. As you’re planting, remember to allow for the vegetation’s growth. A shrub that might spread 18 inches from its trunk should be planted at least four feet from the device, leaving 30 inches between its outstretched branches and the equipment. Periodic landscape trimming should be done to maintain this working distance.
We inspect an average of 2,000 devices monthly, so we appreciate your help in keeping them accessible.
