Duties & Responsibilities

The primary function of the Water Division is to provide consistent on-demand tap and fire protection water service to the customers in the Oldsmar service area. It administers the Florida Department of Environmental Protection’s (FDEP) procedures for distribution of the water supply to the city.

In 2013 the City of Oldsmar opened the Bruce T. Haddock Water Treatment Plant. This Reverse Osmosis Water Treatment Plant (ROWTP) helps reduce strain on local surface water for potable water production by utilizing a previously untapped source of brackish water. Our operators work hard every day to ensure our residents have safe drinking water. They’ve done such a great job that our ROWTP has won the FDEP Plant Operations Excellence Award in 2013 and 2018 and the 2014 Southeast Desalting Association Outstanding Membrane Plant Award.

If you experience a high water bill, the most common cause is a leak.  Look for wet areas in and around your home that are not typical. Check all taps and spigots. Toilet leaks are very common. Try turning off all water in your home and check to see if meter is still registering flow.  If so, call a plumber or number above.

Did you know that a toilet leak can waste from 30 to over 1,000 gallons of water per day? Leaks are one of the most common causes for high water bills. So, fixing a leak can save water and money.

Common causes of toilet leaks

  1. Flapper becomes warped or damaged and does not provide watertight seal on the flush valve. In-tank toilet cleaners can cause flapper damage.
  2. Flapper, trip leaver, or chain loses its alignment with the flush valve, leaving a gap that can cause a leak.
  3. Flush valve develops small cuts or damages that cause a leak between it and the flapper. This is usually caused by grit or sediment.
  4. Fill valve becomes stuck in the open position causing water waste as it flows down the overflow pipe. This can happen when the water pressure changes in your home.

  1. Listen - The toilet should only make refill noise when refilling after a flush
  2. Look - A large leak will cause moving water in the bowl long after the tank has refilled from a flush. For a small leak, place a leak detection tab or food coloring in the tank and wait at least 15 minutes. If colored water appears in the bowl, then you have a leak.
