Mayor implores residents to conserve water, say restoration in Granada Hills, Porter Ranch isn't possible without cooperation

GRANADA HILLS, LOS ANGELES (KABC) — Los Angeles Mayor Karen Bass and other city leaders are imploring Granada Hills and Porter Ranch residents to stop using their tap water so crews can restore water service to more than 9,200 customers in the area.

Bass held a press conference on Saturday with Councilman John Lee, General Manager of the Los Angeles Department of Water Janisse Quiñones and the Los Angeles Fire Department, where they all issued a strong message to the community about conserving water over the next 48 hours.

“I first and foremost want to thank the workers from the Department of Water and Power for all that they do,” Bass said. “The fact that they are here on one of the hottest days of the year and are actually working 24 hours a day to get water flowing through Granada Hills and Porter Ranch, to restore the water.”

Bass passionately urged all Angelenos living in Granada Hills and Porter Ranch to conserve water as workers continue to fix the issue, which has been ongoing for five days.

“Please do everything that you can to conserve your use of water,” Bass said. “We are very concerned that if people continue to use the water that is coming out of their faucets today, it is going to delay the ability of the DWP to get the line back and restored and for your use of water to be back to normal so you don’t have to boil water, so that you don’t have to conserve.”

The Los Angeles Fire Department is in the area out of an abundance of caution, taking extra measures to ensure there is no danger or risk as the area experiences hot weather in addition to the lack of water.

“Please, just don’t use water as much as possible. We have sites where you can pick up water,” Lee said. “We need to build up that pressure, we need to build up that tank, so we can make the necessary repairs, so that we can get out of this mess and go back to normal.”

Since Tuesday evening, crews have been working to replace a failed valve that controls the water flow into the affected areas, while also pumping water into the system. As of 1:30 p.m. Saturday, the 10-million-gallon tank serving the area was approximately 20% full.

“Although you might have water flow and water pressure, using water lowers the level in the tank and overall pressure in the system,” Quiñones said. “Your cooperation significantly impacts the speed of repairs and the impacts to the community.”

The tank has lost an equivalent of 1 million gallons during high-demand periods, Quiñones said. That is equal to 776,000 toilet flushes or 10 Olympic pools.

She stressed that the repair to the valve is complex and involves working around other critical infrastructure 20 feet underground.

Officials said water quality testing to lift the boil water notice will start as soon as pressure is restored in all impacted areas. The goal is to start that Saturday night — but only if pressure is maintained in the system — with the hope that all repairs will be finished by 3 a.m. Monday.

The DWP said crews needed to excavate 24 feet underground to access and repair a valve that was damaged Tuesday.

“The water disruption stems from a deeply buried broken valve on a major 54-inch diameter water pipeline that supplies the Susana Tank serving the area, with approximately 104 miles of water system pipes serving 9,200 customers impacted by the incident,” the utility said. “The repair site is located near critical infrastructure — including oil pipelines, a fiber optic line, and a gas line. The complexity of the operation has now necessitated additional excavation to widen the trench. Repairs are expected to continue through the weekend.”

While the repair work continues, customers remain on a boil water alert and are being urged not to use their running tap water if it happens to be working.

The affected area is bounded roughly by Rinaldi Avenue on the south, Balboa Boulevard on the east, De Soto Avenue on the west and the foothills and hills to the north.

DWP officials reported some progress Saturday.

“As of 7:00 AM, the 10-million-gallon tank serving the area has reached approximately 27% capacity — a strong step forward,” the utility said. “To speed up the process, we installed an additional pump overnight, and two more are on the way this Saturday. These extra pumps will boost water flow, allowing us to begin water quality testing earlier than usual — before repairs are fully complete.”

DWP officials originally said the repairs could take until Friday. The utility noted that accessing the broken valve proved problematic.

Residents in the affected area are being asked to use bottled water for drinking and cooking, keep all indoor and outdoor taps closed, refrain from doing laundry and dishes, and turn off all sprinklers, smart irrigation systems and swimming pool automatic fill systems.

In the meantime, the DWP added two more service sites to help customers affected by the outage, bringing the number of those sites to five.

Their locations are:

• Holleigh Bernson Memorial Park, 20500 Sesnon Blvd, Porter Ranch (water bottle distribution, recycled water distribution, restrooms, showers, mobile laundry units; open 7 a.m.-9 p.m.)
• O’Melveny Park, 17300 Sesnon Blvd., Granada Hills (water bottle distribution, recycled water distribution, restrooms; open 7 a.m.-9 p.m.)
