Why do I smell sewer gas in my dwelling?: All drains and fixtures in a dwelling are supposed to be hooked to a vent pipe that extends up through the roof to expel back pressure in your plumbing system. Drains are protected from gas escaping into a dwelling by a "gooseneck" or water trap in the drain. This is true for floor drains, sinks, and toilets. If this water in the trap evaporates because of extended non-use, the gas can escape into the dwelling. A simple solution is to add water to that drain and any drain which is not used that often. If this does not solve the problem, it would be a good idea to have your venting system inspected.

4. Is it OK to flush "flushable" wipes?: No. Flushing any type of wipes, even if labeled as "flushable", may cause the pipes to clog and raw sewage to back up into your home or business. Toilet paper is the only paper product that should be flushed.

5. The water in my toilet just sprayed into the air and made a mess. What's going on here?: The sewer utility crews use a high-pressure jet of water to clean the sanitary sewers in the street. The sewer system in your home or business is vented through a pipe that runs up through your walls and out your roof. This venting system is designed to relieve pressure in the sewer system so gases in the piping come out through the pipe in your roof, and not through your toilet or drains. If this is what is occurring, then your venting system may be plugged. sometimes this is caused by birds or squirrels building a nest in the vent pipe on your roof. It would be a good idea to have your plumbing system inspected.

6. Where can I dump the holding tank on my RV?: There is an RV and Septic dumping site at the intersection of Wilson Avenue W and River Road. It is in the parking lot next to the big blue tanks. There is no charge for RV waste.

7. Can I put anti-freeze or motor oil down the drain?: Do not dispose of your used anti-freeze or motor oil down the sewer. The sewer use ordinance also prohibits the dumping of such material down the drain. The City Solid Waste Site accepts used motor oil from City residents during their normal open hours. Anti-freeze is accepted during the City's annual Clean Sweep Hazardous Waste collection event.
