Two utility projects win top honors

Last Updated: 6/17/2016

Two Environmental Utilities (EU) infrastructure projects and the staff that managed them were among  other regional projects that received top notch awards at the Sacramento Section of the American Society of Civil Engineers ceremony held at the Crocker Art Museum in May.

These projects are very different in scope, but provide a shared benefit: safeguarding resources in Roseville.

Roseville Intertie and Zone 4 Transfer Pump Stations

While Roseville’s primary water supply is from Folsom Lake, we’re continually developing interagency agreements and growing our groundwater program to provide additional back up supply if we ever need it.

This was the case when we began a project to develop two pump stations back in 2014, after the region experienced several years of dry conditions and Folsom Lake was at a record low. With these conditions in mind, we began plans for an emergency drought response that would allow us to supply potable water from neighboring agencies and our groundwater wells to areas of the City normally serviced exclusively by surface water from Folsom Lake.

“We were able to develop this project with $1.1 million in grant funding,” said Jose Lopez, senior engineer. “The grant covered construction costs to build the pump stations, which allows us to move millions of gallons of water per day from Sacrament Suburban Water District and from our groundwater well field from within Roseville to other parts of the city.”

The project cost just over $3 million but was offset with Prop 84 funding, nearly covering half the cost.

Dry Creek Trunk Sewer Bank Rehabilitation

After heavy rains in 2012, the bank along a portion of Dry Creek exposed a 39-inch sewer pipe carrying wastewater to nearby Dry Creek Wastewater Treatment Plant. Because further erosion might damage the pipe, the city was anxious to stabilize the creek bank before the rainy season in 2014.

“The work required diverting the creek to construct a rock embankment with plantings to help stabilize the soil against erosion,” said Ed Winston, associate engineer. “The proximity of the project to the creek required an extensive permitting process with state and federal agencies, which required the city to undertake additional measures to protect sewer lines and the creek habitat during construction.”

Thanks in part to the generous cooperation of landowners on either side of the creek, the contractor was able to complete the project in October 2014—a week ahead of schedule.
