Sacramento County Water Agency - Big Horn Well No. 7

​Background

SCWA is expanding water supply for the Big Horn Water Treatment Plant in which an offsite well (Well #7) will be constructed for upcoming development and expanding population in the area.  The first phase of the project will drill a test hole to assess the water quality and geology at the well site northeast of the corner of Lotz Parkway and Auto City Drive.  The construction of the new groundwater well will be next to the Elk Grove Auto Mall.

Project Location

 

Upcoming Work

There will be two periods of drilling activities, once for the test hole and later for the municipal well. The drilling activities will require 24-hour operations during critical portions of the project. The test hole will require one to two days of continuous drilling while the municipal well will require three to four days. The 24-hour-a-day operation is needed to keep the hole open while it is being drilled. The work area must be illuminated during the 24-hour drilling period to ensure the safety of workers.

SCWA will make every effort to shorten the length of time required for the drilling operations. The drilling contractor is committed to minimizing impacts from light and noise throughout the work conducted at the site, but disturbances should be expected.

What To Expect

This phase of the project drilling the test hole will have minimal impact outside of the site. However, there will be discharging of excess water for the next phase – drilling of the municipal well - and eventually into the sewer or storm drain depending on the turbidity level . Unfortunately, there is no practical method to capture or re-use the discharged water. The discharged water will ultimately discharge to the storm drain/sewer system along Lotz Parkway.  The water quality of the discharged water will be frequently tested to ensure it meets requirements for discharge.

Project Schedule*

Test Hole Construction: Late June– Early July

*(Some residents received door hangers indicating construction would begin June 21, however, due to drill rig repairs the drilling start date was rescheduled)

Hours of Operation

Prior to, and following 24-hour operations, work will be conducted during daylight hours between 7:00 a.m. and 6:00 p.m. on weekdays, and 7:00 a.m. and 6:00 p.m. on weekends.
