Repairs to fix a major washout on the Columbia Irrigation District main canal near the Hills West Estates off Columbia Park Trail proceeded into a second day Thursday.
CID officials said crews from Ray Poland and Sons of Kennewick would continue working nonstop with heavy equipment until the repair is complete.
In addition to filling in an estimated 8,000 to 10,000 cubic yards of dirt and rock that washed away, about 150 feet of new canal has to be constructed, said Russ Pelleberg, assistant manager.
"We've been making good progress," he said. "Hope to pour concrete liner Saturday and put water in the ditch Monday. That should get (water) into the Kennewick area by Tuesday, with lower end, which is Finley, on Wednesday."
Pelleberg said some construction support has come from the Kennewick Irrigation District through the loan of a couple of dump trucks and drivers.
The canal failed early Wednesday, dumping all of the water from the main line into the Yakima River and leaving about 4,000 people without irrigation water in Finley and Kennewick.
About 3,000 of them are CID customers, and approximately 1,000 are customers of the KID, which uses the CID system to bring water to several of its pressurized service areas.
CID officials originally estimated it would take about a week to complete repairs and restore water to affected customers.
