CITY TRUNKLINE REPAIRS ON COLDWATER CANYON AVENUE COMPLETE

DEPARTMENT WORKING TO PUT WATER MAIN BACK INTO SERVICE

LOS ANGELES – The Los Angeles Department of Water and Power (LADWP) reports substantial progress on the 62-inch City Trunkline which ruptured under Coldwater Canyon Avenue just south of Ventura Boulevard late Saturday night.  Working overnight for the third day in a row, LADWP crews completed all repair work to the massive steel-riveted pipe early this morning.  Pressure tests to check for ancillary leaks have confirmed the repaired line’s integrity and water is currently being pushed through the pipe at increasing levels of pressure. Once full pressure has been reached, the main will be put back into full service, which is expected to happen today.

Water quality tests have confirmed the chlorination process for the line that began last night was successful and the LADWP’s high water quality standards have been met. At no time during the incident were there any adverse impacts to water quality although some customers may have experienced mild turbidity.

No customers are currently without water service due to the trunkline rupture or any of the subsequent repairs.

After the line has been restored to service, crews will begin backfilling the street blowout with compacted sand and crushed rock.  The backfill material will fill in spaces in the dry fill that is currently present, creating the ideal compaction necessary for street repairs to begin.  The backfill process will require up to two days for placement and proper compaction and testing.  Thereafter, when LADWP’s portion of the fill work and stabilization is complete, the Los Angeles Bureau of Street Services will begin repaving work.

At this time, it is not possible to estimate when street repair work will be complete and Coldwater Canyon Avenue will be reopened.  The media and public will be updated as work continues and a better estimate of completion is known.
