LONE TREE WASTEWATER TREATMENT PLANT
Sanitary sewage service for Inverness Water and Sanitation District customers is provided by a joint treatment plant operated by the Arapahoe County Water and Wastewater Authority and partially owned by Inverness Water. This plant was completed in the summer of 2008 in full conformity with all federal and state laws. Inverness retrieves treated wastewater from this plant to irrigate the community’s landscapes seasonally.
Located adjacent to the Cherry Creek Reservoir, the Facility helps protect the Reservoir’s water quality for swimming, boating, fishing and other recreational activities. In order to meet one of the most stringent phosphorous discharge limits in the country, the Facility’s design incorporates a unique Advanced Water Treatment at the end of the wastewater’s purification process.
Upon reaching the plant, the wastewater first encounters preliminary treatment where items that either float to the surface or settle to the bottom are removed. The wastewater then flows to secondary treatment where the water is biologically treated through aeration. Aluminum sulfate is then added to precipitate phosphorous and this water is run through advanced filtration before being discharged to the creek per the requirements of our discharge permit.
The facility helps conserve our water resources and has integrated a reclaimed water program, which allows the re-use of our treated water by trading it for water diverted at our wells upstream on Cherry Creek.

WHAT TO NOT PUT DOWN THE DRAIN
NO food grease (unless you have a District approved and inspected grease trap): Collect cooking oils, lard, meet fats, butter and dairy fats and throw them in the trash.
Do not flush diaper wipes, wet-whips or personal hygene products down the toilet. These items will eventually clog your home lines causing potentially costly back-ups. They can also contribute to sewer system line clogs that can impact many homes and cause costly cleaning and repairs for the District. It is a myth that hot water, soaps or the dishwasher will “dissolve” grease into a harmless state.
NO pharmaceuticals: There is growing concern about “emerging contaminates” in surface water and alluvial (shallow renewable) ground water supplies originating from pharmaceuticals both dumped down drains and from human/animal waste. If you have unused our outdated medicines, mix them with wet coffee grounds (a neutralizer and absorbent) in a secure non-leaking container/bag/jar and throw them in the trash. Landfills take precautionary steps to prevent waste from leaching into water supplies. Some pharmacies will take back unwanted pharmaceuticals for proper disposal.
NO petroleum based products or chemicals not intended for household cleaning use. This includes gasoline, diesel or other fuels, petroleum or silicone based lubricants or solvents or glycol type products like anti-freeze. These can do significant system and environmental damage.
NO items like baby or disinfect wipes, diapers, cleaning pads, paper towels, napkins, dental floss. These do NOT breakdown and will clog either your home’s pipes or the sewer system pipes.
NO paints or solvents. Wash paint brushes out in a bucket and dump over turf areas or wash with the hose over turf areas. Paints can contain harmful chemicals and clog lines.
NO RV waste disposal. Use approved RV waste disposal services. This can overwhelm residential septic systems and sewer lines and result in backups into buildings. Avoid all “gunky” things. It is best to collect and throw away food preparation items like potato and similar peelings, coffee grounds and food waste in general, even if you have a garbage disposal. It is a myth that the garbage disposal grinds these items into a harmless mix. Over time, excessive garbage will accumulate and clog pipes.
