Douglas County Household Chemical Roundup on September 21, 2019

Posted by kguite

You’ve cleaned your house from top to bottom, now it’s time to dispose of common hazardous household products that you don’t use or need any more as you button up your home for fall.

The Douglas County Household Chemical Roundup makes it easy to drop off your household hazardous waste. Go to the Castle Rock Water at 175 Kellogg Court on Saturday, September 21, 2019, from 9 a.m. to 3 p.m. (The utilities yard is located at 175 Kellogg Court, west of I-25 and south of Santa Fe Drive.)

Many common products found in the home may be hazardous and should be used and disposed of carefully. These include motor oil, antifreeze, vehicle batteries, solvents, house and garden chemicals, compact fluorescent lights (CFLs), fire extinguishers, items containing mercury, propane tanks (1-20 pounds), paint, and passenger vehicle and pickup truck tires off the rim. Proper disposal at the Roundup helps prevent the potential of accidental poisonings and fire hazards in the home.

Residents drive up and volunteers will unload the materials. Douglas County participants should bring proof of residency, such as a driver’s license or utility bill and $25 per vehicle to offset the high cost of hazardous waste disposal. Residents are encouraged to pre-register in advance online at''

A FREE Drop-and-Swap area is available where citizens can pick-up unused household cleaners, car wax, antifreeze, fertilizer, and garden products that are still in their original containers. Reuse of these items promotes environmental stewardship by reducing the amount of waste disposed and additionally decreases the total disposal cost of the Roundup.

Residents with architectural paint and paint products can now conveniently drop-off unwanted paint for free recycling year-round at many locations in the Denver Metro Area. A map of participating Paint Stewardship Program retailers in the can be found at'' Simply click find a drop-off site and type in your address to find the nearest participating paint retailer for year-round drop-off service for accepted paint products.

The Douglas County Household Chemical Roundups cannot accept waste from businesses, and are not able to accept radioactive waste, compressed gases other than propane (1-20 pounds), smoke detectors, tractor tires, electronic waste of any kind, scrap metal, 55-gallon drums, waste containing asbestos, or explosives.
