Wastewater Collection System
The City of Thornton Wastewater Collection System maintenance staff is charged with protecting the public's health and safety by maintaining the integrity of the new and existing systems. The maintenance team is responsible for monitoring the condition of the wastewater infrastructure through tv inspection for root intrusion, breakage, and infiltration. Washing of sewer lines ensures that lines are free of obstructions.
Wastewater personnel may be seen in public responding to calls or performing routine maintenance wearing additional protective equipment. This includes protective gowns or white protective coveralls, goggles, masks, and gloves. These are recommended to protect personnel and the citizens we serve.
Sewer taps are scheduled and performed for new development. The city also inspects six sewage lift stations twice per week, and emergency generators are exercised weekly to provide reliable operation.
Don't Flush This Stuff!
- Disinfecting wipes
- Baby wipes
- Mop refills
- Paper towels
- Dental floss
Even if it says 'Flushable,' these items clog your sewer system resulting in an expensive cleaning and possible damage. Increased power costs to run a clogged pump and maintenance costs to the city's sewer system are passed on to the consumer at higher sewer rates. Don't use your toilet as a trash can! The only thing that should be tossed in the toilet is toilet paper!
Cooking grease is not a good match for your sanitary sewer system! Some people think the grease will disappear by adding hot water to the kitchen faucet. There is some truth to this. The grease will break down with heat from the hot water, but when it cools down, it will solidify in your private sewer service, the city sanitary sewer system, or both. Sewer pipes are sized to accommodate the anticipated maximum flows that can be delivered through the pipe. As fats, oils, and grease cool underground in the sewer pipes, it attaches to the pipe walls and lessens the capacity for maximum flow levels. Eventually, the grease can build up enough to nearly or completely block off all sewer flow in an area near you. When that happens, a backup in your home plumbing can occur or cause a blockage in the city sewer system that can result in a sewer spill from one of the thousands of sewer manholes that we maintain. Sewer spills could result in discharging untreated sewer into storm drains, creeks, and waterways in our neighborhoods. Sewer spills impact the environment and the habitat that depends upon clean water to survive.
Through all this, there is hope and an easy way to reduce and eliminate the problems that fats, oils, and grease can cause in the sewer system! It's as easy as using a standard-sized food can with the lid completely removed to pour your household cooking grease into. As it cools, it, too, will start to solidify in the can, much like it would have done had it been washed or flushed down the plumbing drains. When they get close to being full, discard the cooled grease can into your garbage. This action alone will help to reduce sewer blockages and sewer spills, help protect our environment, and reduce extra maintenance costs to keep the sewer lines free of grease deposits. You can make a difference!
