UPDATE: Broken Water Main Floods Street, Deputies Fear Sinkhole May Develop

A broken water main is flooding a street and causing asphalt to warp.

Update, 1 p.m. Residents in the 19000 block of East Mauna Loa are not expected to be without water today, according to Surburban Water Systems.

According to Suburban Water Systems spokesperson Michael Nutt, a 10-inch split at he junction of two lines at the intersection of Mauna Loa and Barranca avenues caused water to gush into the street at around 1 a.m. Tuesday.

While the cause of the break is still unknown, Nutt said broken pipes are common in that area of Glendora where pipes are 50 to 60 years old.

The pipes are expected to be replaced Tuesday.

Update, 3:37 a.m. Surburban Water Systems has shut off water access to stabilize a broken water main that had been gushing water down Barranca and Mauna Loa avenues in an unincorporated area of Glendora early Tuesday morning.

It is unknown how many residents are affected and how long the water will be turned off.

The flood was reported shortly after 1 a.m. in the 19000 block of E. Mauna Loa Ave. According to Los Angeles County Sheriff deputies, the pressure from the flooding water was causing the street asphalt to warp, causing concerns that, if left unattended, a sinkhole would develop.

There is no word yet on what may have caused the water main to break, although deputies noted that old pipes in an antiquated water system may be the cause.


2:17 a.m. Water is flooding a neighborhood in an unincorporated area of Glendora and Los Angeles County Sheriff deputies fear the flood may cause a sinkhole.

The water main break occurred around 1 a.m. Tuesday in 19000 block of Mauna Loa Avenue. The volume of water is causing asphalt to warp, according to Deputy Ojeda of the L.A. County Sheriffs San Dimas Station.

There are reports that nearby residents may be without water.

Deputy units are currently on the scene to block traffic and Los Angeles County Public Works and Surburban Water Systems have been dispatched to assess the situation, said Ojeda.

This story will continue to be updated as more information becomes available.

I was wondering why the water pressure was super low.
