What Not To Flush

Keeping the Tyngsborough Sewer system flowing continuously is a priority for the Sewer Department. We've put together a quick online resource for residents to help us make your sewer system run more smoothly.

What Not to Flush

When you use your toilet, shower, washing machine, or dishwasher, wastewater leaves your home through pipes that connect to the town sewer system.

A clear drain is a happy drain - please be kind to your toilet and sewer system.

Many materials frequently flushed or poured down the drain can harm the pipes that connect to town sewers as well as the town sewer system. Every property owner connected to the town sewer system can be a potential contributor to sewer problems, and a potential victim of those problems.

Putting the wrong things down the drain can damage the sewer system, cause sewer backups in your home, and sewer releases to the environment. Anyone who uses the town sewer system should be responsible for what they flush or pour down drains.

Don't Flush This

Basically, the only thing you should ever flush down a toilet is human waste (urine and feces) and toilet paper. Here is a list of some things to keep out of the toilet.

  • Disposable diapers
  • Tampons
  • Cotton balls and swabs
  • Sanitary pads
  • Unused medications (put original containers in a plastic, zip-lock bag and throw the bag in the trash)
  • Condoms
  • Cleaning wipes of any kind
  • Facial tissue
  • Bandages and bandage wrappings

Fats, Oils & Grease (FOG)

Grease in sewer pipes causes sewer maintenance problems for property owners and the town. Never pour grease in your sink drain and try to use your garbage disposal less.

Grease is a byproduct of cooking. It comes from meat, lard, oil, shortening, butter, margarine, food scraps, baking goods, sauces, and dairy products.

When grease washes down the sink, it sticks to the insides of the pipes that connect your home or business to the town's sewer. It also coats the insides of the town's sewer pipes. Eventually, the grease can build up until it completely blocks sewer pipes. That can create difficult and expensive maintenance problems for both the town and private property owners. Blocked sewer pipes can cause raw sewage to back up into your home or business, or overflow into streets and streams.

Garbage disposals don't keep grease out of sewer pipes. Products that claim to dissolve grease may dislodge a blockage, but will only cause problems farther on down the line when the grease hardens again.
