The water district is building new facilities at the Rinconada Water Treatment Plant to ensure a reliable water supply. And we’re looking at different ways to make sure our work doesn’t impact your neighborhood.
Look at the hillside just above the work areas at the plant to see one of the most effective tools for protecting your homes from storm water runoff.
We’re talking about wattles, those cylindrical wheat straw ropes often placed and staked in construction areas and around streams. Without them, you might see a lot more excess water running off the job site.
When it rains, water just doesn’t sit in one place. Some of it seeps into the ground and helps replenish our groundwater basin, but some will also move wherever gravity takes it, picking up sediment and potential pollutants along the way.
“These wattles keep that runoff from leaving our plant and ending up on the nearby streets,” said Mike Munson, the project manager for the current rebuilding project at the water treatment plant. “So, they’re pretty handy barriers. We like to make sure plenty of them are in place, especially when we get some rain.”
The state of California Water Board requires the use of wattles at industrial and construction sites through its Storm Water Pollution Prevention Plan. The wattles naturally biodegrade over short periods of time and can last up to two years.
“Wattles are an essential part of any construction project,” Munson said.
