Customer question: Do storm sewers go to the water treatment plant?
There are three water systems: drinking water, wastewater and stormwater. The drinking water purification facility, treats water to a purity that is safe for drinking. These standards are mandated by strict local, state and national regulations which Castle Rock Water goes above to ensure a higher quality drinking water. Wastewater is the water that comes from the toilet, shower and sink drains in your home or business. It gets treated at the wastewater treatment plant to strictly regulated environmental standards before it is released into the creek. Stormwater is the water that flows through the streets into storm drains (storm sewers) and channels within our community. It leads directly to the creek and does not get treated before it reaches the creek. This is why it is so important to pick up trash, prevent drips from our cars and put pet waste into the trash.
Castle Rock, like most communities, pulls water from the nearby creek. Though a more sustainable source, renewable surface water does require more treatment than deep aquifer water to ensure it is safe and pure. At the Plum Creek Water Purification Facility, the water goes through many rigorous treatment processes. This facility is currently under construction as we expand to better treat multiple sources of water and ensure a safe and pure drinking water. This drinking water treatment plant will again be open to the public for tours once construction is completed.
