Richardson says a boil water notice in place since Wednesday has been lifted, and water quality has returned to normal.
The city issued a boil water notice to residents on the southwest side after an equipment malfunction on Wednesday caused a drop in the water pressure in the 767 water zone. According to a news release, the malfunction went undetected because the telemetry equipment failed to notify operators, and the water pressure ultimately fell to zero.ย
City crews collected water samples from the impacted area overnight Wednesday and delivered them to the North Texas Municipal Water District (NTMWD) for testing on Thursday morning. The test results are expected sometime early Friday afternoon and will determine when the boil notice can be lifted.
When water pressure drops, people are asked to boil water because the lower pressure in the pipes can allow contaminants, like harmful bacteria, to enter the system through cracked pipes. Boiling the water kills the bacteria, sanitizing the water. If the water isn't sanitized, the bacteria could harm children, seniors, and others with weakened immune systems.

The city said the notice on Thursday affected about 17,000 customers, including residential areas and businesses. On Thursday, the Richardson ISD closed Dover Elementary, Heights Elementary, Arapaho Classical Magnet, Richardson West Junior High, and Richardson High due to a lack of water.
Though the boil water notice was still ongoing, the Richardson ISD reopened the campuses Friday morning after preparing the school buildings to operate with the water loss by covering water fountains and refill stations and restocking the bottled water supply. Additionally, the cafeterias planned to serve โcoldโ meals for breakfast and lunch that do not require water in kitchens to prepare, rinse, or clean up. The district said that, per the cityโs guidance, restroom tap water is safe for washing hands when combined with soap and washed vigorously for 20 seconds. The water issues are not expected to extend into next week.
