The Treatment Process
The treatment process at the Klein Water Treatment Facility starts as water from the District's shallow wells, which range in depth from 80 to 100 feet, is pumped into the treatment plant.
This incoming untreated water is called influent. The influent water passes through the granular activated carbon filters which remove TCE and other organic chemicals from the water by a process called adsorption (carbon attracts the organic chemicals to its highly porous surface).
From Treatment to the District
After chlorination, the filtered water flows into the clearwell where it is blended with treated water supplies from Denver Water. Transfer pumps send the blended water from the clearwell to the District reservoirs.
Finally, booster pumps transfer the water from the reservoirs to District customers.
SourcesThe sources of drinking water include rivers, lakes, streams, ponds, reservoirs, springs, and wells. The District Water System blends multiple water sources to provide you with high quality drinking water.
Your water consists of:
- Groundwater from 11 wells which draw from the alluvial aquifer tributary to the South Platte River
- Eight deep wells which draw from the Arapahoe formation
- Treated surface water from Denver Water
Further TestingThe District tests for over 240 contaminants on a regular basis. Some contaminants, such as free-chlorine, are tested on a daily basis. Our water operators and lab analysts collect and analyze samples from many locations
- Production wells
- Monitoring wells
- Treatment plant activated carbon filters (contactors)
- Finished water reservoirs
- Distribution lines
- Customer taps
All drinking water, including bottled water, may reasonably be expected to contain at least small amounts of some contaminants. The presence of contaminants does not necessarily indicate that the water poses a health risk.
Protection of our water sources is a fundamental and continuous program at the District. We're doing everything we can to safeguard our supplies. All residents and business owners are encouraged to report suspicious behavior that may affect our water resources.
