Roxborough Water and Sanitation District Annual Flushing Program

Every spring, the Roxborough Water and Sanitation District (RWSD or District) completes the annual flushing of the distribution system. Flushing the distribution system removes any naturally occurring minerals in the water that may adhere to the water pipes during the winter when use is low, thereby protecting water quality and avoiding any problems with discolored water (see the FAQ for more details). Flushing also provides an opportunity to test hydrants throughout our system to ensure they are in good working condition. We post electronic signs throughout the District well in advance of the start of the annual flushing to let residents know this annual event is occurring.

Flushing relies on high velocity flows to accomplish the water quality goals. So, you’ll see hydrants running full blast and water running along the curb and gutter to the storm sewers in most of the District. There are some areas where we must rely on natural drainages, ditches, and culverts, so please try to keep those areas free of weeds, bushes, debris, sand, and gravel. We work very hard to avoid any impact to private property. If you see a hydrant running, look for one of the Roxborough Water and Sanitation District white trucks, and if you still have questions, please call the office. All hydrants belong to RWSD – not West Metro Fire – and there is no reason to call the fire department.

The 2023 flushing program will commence next week and should be complete by early April, weather permitting. We post an electronic sign at various locations throughout the District while we are flushing. We start at the far end of the system, which is the south end of Roxborough Park, and will post the electronic sign at the entrance to Roxborough Park prior to the start. Please make sure any ditches and culverts are free of weeds, bushes, and debris and accumulated sand and gravel.

Efficiently providing you with safe, reliable water is our number one priority, and we take it very seriously. Our dedicated team of professionals work very hard to meet the needs of our customers. The annual flushing program is an integral part of that work, and we do our very best to do it in a way that keeps the water safe and causes as little inconvenience as possible. Thank you for your cooperation.
