Your bill is based on how much water passes through your meter, which is read monthly. Since the movement of water is the only source of energy the meter has, anytime you see a hand moving on the meter, it definitely means there is water moving through it. Some causes for high bills are: size of household, size of home or yard, and more days between readings. We strive very hard to read every 25 to 35 days. Another reason for a high bill is a leak. If you discover a leak, there are procedures set up to help with the large bill. Please see question Number 10.

It is the policy of Terrell Water Utilities to allow a concealed leakage adjustment once in a twelve month period for an account, upon presentation of plumber's bill or other documentation to show that a leak was present and has been repaired. The documentation must show date of the repair in order to know what bills were affected by the leak. This adjustment can be up to one-half the leakage up to one-half of a single monthly bill. We will review the usage during the same time period the previous year and determine how much leakage is involved. Water loss due to pranksters, vandalism, etc., does not fall into this category due to no assurance that the circumstances will not reoccur and the limited control of each customer preventing such an occurrence.

Wastewater (sewer) is the used water that goes down the drains inside our houses and businesses.

Even though the meter records every gallon used, you're billed in increments of 100 gallons. When the meter is read the meter reader will round down to the nearest 100. If you use within the 100 gallon range of water each month, the bill will be the same.

The cost of water service varies based on the type of production system (lakes - higher, wells - lower) that is used. Our rates are only increased to cover required operating and capital (systems improvement) costs necessary to ensure a reliable, healthy, and safe water supply.

Yes. Fluoride can naturally occur in water and is also added by North Texas Municipal Water District to adjust the level below what is set by EPA. Fluoride is recognized by the American Dental Association as a deterrent to tooth decay based on over 70 years of scientific research, especially in young children.

The hardness is determined by the amount of calcium in the water. The water supplied by North Texas Municipal Water District is considered moderately hard.

The water in Terrell is supplied by North Texas Municipal Water District (NTMWD) and primarily is sourced from Lake Tawakoni. NTMWD started a new water treatment facility in 2015 which receives water solely from Tawakoni. Lakes Lavon, Texoma and Chapman are alternate sources treated at the Wylie Plant in the event Tawakoni is temporarily shutdown.

Absolutely. Water Quality staff test multiple locations throughout the system daily. More extensive monthly and quarterly tests are conducted by both City staff and companies contracted by TCEQ.

You may report anything unusual here.

Water main breaks or heavy water usage required to fight a fire may occasionally discolor your water. The cloudiness or discoloration is caused by sediment dislodged by sudden pressure changes in the water system. The water will clear up as these sediments are flushed from the system. This water is safe to drink but you may want to postpone doing your laundry until the water clears to avoid staining clothes.
