Project details

Starting on June 3, 2024, EBMUD crews will begin installing a new water pipeline to enhance water service in your Lafayette neighborhood. Please refer to the detour map below to see how St Marys Road will be affected. Side streets intersecting with St Marys Road will also experience temporary impacts as work progresses. The project is expected to continue until October 2024, and the duration of construction on each street may vary. Final paving will follow the completion of construction. For details on the affected work area, please review the accompanying detour map.

Schedule

Work hours are 7 a.m. to 4:30 p.m., Monday through Friday. We will provide traffic control. Residents may experience delays of up to 10 minutes when entering and leaving the work area. If you have special needs, please call us and we will make every effort to accommodate.

What to expect

Equipment and materials will be temporarily located in your neighborhood during construction.

After the new water pipeline is installed, crews will transfer water services, install fire hydrants and make final connections.

Once construction is completed, material and equipment will be removed within 1 to 2 weeks.

Water service interruption

Crews will notify you with a door hanger, regarding planned water service interruption to your property. After a service interruption, there may be air in the pipes that may loosen particles in your home plumbing. Close your toilet water supply valves, and then run water from your front hose bib, bathtub and/or cold water faucets for 1-3 minutes. This will dispel any air or loosened particles from your household pipes. If any water quality issues remain after flushing, please call us.

Paving

The daily asphalt paving applied during construction is temporary and serves to ensure a safe road surface. Final paving will take place after the pipeline work is finished. Please note that it may take up to 90 days or longer before the final paving is completed. This pipeline replacement is being undertaken at the request of the City of Lafayette to precede the city's planned repaving of the entire St Marys Road.

Flushing for water quality

After pipe installations or repairs, EBMUD crews may flush water lines with large volumes of water to ensure water is clean and safe. When crews flush pipes, customers may see water discharged into tanks or storm drains. Flushing is a critical step to keep your water safe by removing sediment and discolored water following a repair or new pipe install. EBMUD values conservation and water reuse, especially during drought, and works to reuse flushed water whenever possible. Learn more.
