How Drinking Water is Treated
DWU
uses chemical treatment, settling, filtering and disinfection to purify
drinking water. The chemicals we use include: chlorine and ammonia
(which combines to make chloramine) or ozone to disinfect the water;
lime and iron sulfate to remove suspended solids in the water and for
corrosion control; activated carbon to control offensive tastes and
odors; and fluoride to help prevent tooth decay. We use chloramine
instead of chlorine to protect the health and safety of our citizens.
Studies have shown that using chlorine by itself can cause a reaction
in the water that leaves by-products called trihalomethanes. Some
studies indicate that trihalomethanes could be harmful if consumed in
large quantities over long periods of time. Dallas water is considered
non-corrosive, which means that it is less likely to leach lead from
pipes than water that is corrosive. The combination of our treatment
processes and the non-corrosive nature of Dallas water results in
exceptionally high quality, safe drinking water.
Where Does It Go After It Is Used?
Pumped through the wastewater system to one of our two wastewater treatment plants. The water is then cleaned and returned to the Trinity River, where it flows downstream and is used by other cities.
Operation WaterShare
DWU and The Salvation Army have joined forces to sponsor Operation WaterShare. Through Operation WaterShare, DWU customers and employees can donate money to help people who are temporarily unable to pay their water bills.
