A six-man crew from East County will be making a trek to help the Paradise Irrigation District in northern California. Four field employees from Helix Water District and two from Padre Dam Municipal Water District will leave Aug. 18 and spend five days in the Butte County town of Paradise, which was gutted last November when the Camp Fire scorched more than 150,000 acres and burned down nearly every building in town, about 19,000 structures. At least 85 people died with dozens more injured in the deadliest and most destructive wildfire in California history. As it recovers and rebuilds, safe drinking water is one of Paradise’s major challenges.
