Three water mains ruptured earlier this week, sending water gushing onto streets in Hollywood and Hancock Park, and caking sidewalks, streets and lawns with mud. Although water main breaks are a daily occurrence citywide, there is no correlation between the back-to-back pipe ruptures, according to Los Angeles Department of Water and Power (LADWP) officials.
“The different pipes are not exactly related to the same trunk line,” said LADWP spokesperson Michelle Figueroa. “There is no direct correlation.”
Trunk lines are main water supply lines greater than 20 inches in diameter that deliver water to LADWP’s vast grid of underground pipes. LADWP operates approximately 500 miles of trunk lines citywide.
Figueroa said the main reason for continuous water main breaks, which average three per day, is the size of the system and the aging infrastructure.
“It’s one of the largest drinking water systems in the country,” Figueroa said. “Five hundred million gallons of water are being used per day in L.A.”
Despite the frequent pipe ruptures, Los Angeles only has a 3.5 percent annual water loss, which includes water main breaks as well as evaporation and water used for firefighting, according to Figueroa.
A water main ruptured at approximately 12:56 a.m. Monday in the 4800 block of West 3rd Street in Hancock Park. Repairs to the eight-inch pipe were completed at approximately 4 p.m. The rupture disrupted service to five residences, according to LADWP spokesperson Albert Rodriguez.
Another water main ruptured at approximately 6:15 a.m. in the 6400 block of West Odin Street near the intersection of Cahuenga Boulevard in Hollywood. The eight-inch pipe was repaired and the street was reopened to traffic at approximately 3 p.m. The rupture affected 15 residences, according to Rodriguez.
Crews removed the asphalt surrounding the ruptured water main on Odin Street. The damaged pipe was excavated and replaced later that morning.
An additional water main ruptured on Tuesday at approximately 5:10 a.m. in the 1100 block of North Wilcox Avenue between Lexington Avenue and Santa Monica Boulevard, according to LADWP spokeswoman Carol Tucker.
“The pipe was from 1930. It had a low grade with a high likelihood of failure,” Tucker said.
Approximately 10 to 15 customers lost service until repairs were finished at approximately 2 p.m., according to Tucker.
