Curb Stops

The curb stop/box is the property of the water utility and may only be turned on/off by an authorized employee of the water utility. Plumbers may turn the water on to test their work but must leave the water turned off upon completion of the work. Please call 222-2525 to request that a curb stop/box be turned on/off. A construction meter is required for all water use.

A 48-hour notice is required to schedule an appointment to have a curb stop/box turned on/off.

Do Your Part to Protect Our Water and Collection Systems

There are ways you can help to protect our public collection systems.

Do Not Flush It

Never flush anything down your toilets except toilet paper and human waste. Even items that are marketed as "flushable" have the potential to clog in the collection systems and cause back-ups. Read more.

Only Rain Down the Drain

The storm drains in our streets are part of our storm water collection system which discharges into our lakes. Leaves, grass clippings, litter, vehicle oil, etc. in the gutters will flow into the storm water collection system and into our lakes, causing weed growth and pollution. 

Ways you can help our lakes:

  • Mulch your grass clippings and leaves into your lawn
  • Sweep or blow any grass clippings or leaves off the street and out of the gutters
  • Eliminate or minimize your use of fertilizer on your lawn
  • Compost leaves and lawn clippings
  • Never pour anything into the gutters or sewers, including waste oil, detergents, or chemicals.  This is referred to as an illicit discharge and is illegal.  If caught, a person who created the discharge could be fined.
  • Adopt a storm drain
