LILIHA, Oahu (HawaiiNewsNow) - It was a busy Sunday for the Board of Water Supply after responding to six water main breaks, but crews are making progress on repair work.
There were six water main breaks, five of which were in the Liliha area.
There were two 8-inch water main breaks on Alaneo Street, but both have been repaired, and water service has been fully restored.
There were also two water main breaks on Lanakila Avenue. The break between Keola Street and Kunawai Lane has been repaired. Water service was restored to all affected customers and all lanes of Lanakila Avenue were re-opened around 7:45 a.m Monday.
BWS officials say the break between North School Street and North Kuakini Street on Lanakila Avenue will be repaired later. However, the road is open and no homes are affected.
Crews completed work on an 8-inch water main break on Nalanui Street that happened around 8 a.m. Sunday.
There was also yet another water main break on Hoauna Street in Kaneohe, but repairs have been made and water service has been restored.
BWS Information Officer Kathleen Pahinui said they can't pinpoint any specific cause why the pipes broke the way they broke and so close together. However, she said they are investigating.
"We think sometimes in older pipes, the system, and this very rarely happens, but it can happen where a shift in the pressure could cause a little bit of a break down the road. And we think on Alaneo Street, that's what happened. On the others, were not sure," said Pahinui.
Pahinui said they will be sending out the failed pipes for testing to determine an exact cause.
She said the pipes are old and that is a contributing factor. She said most of them are from the 1960s and the one on Lanakila Avenue by Keola Street is from the 1930s.
Pahinui said the area was already slated for pipe replacement prior to this happening. She said it is still a very high priority area along with many others areas across Oahu.
"Puuwai Street has had a number of breaks over the past few years. So that's slated, that's going into design. McArthur Street up in Waianae has had a number of breaks, more than we would want. So we're putting in for that project to replace the pipes up there too," Pahinui said.
