WA DOH Inquiry: Is Your Water Service Line Made of Lead?
At the direction of the EPA, Sierra Vista Water Association is conducting an inventory to determine whether any service lines to the homes we serve contain lead.
Learn if your home is at risk and how to determine if the service line to your home contains lead.
SVWA's two storage tanks were cleaned in the fall of 2024. This biannual maintenance costs about $3,000 for both reservoirs.
The process of draining each tank, pressure washing with a bleach solution, refilling with water and conducting bacteria testing takes several days. Residents are served by SVWA's other reservoir in the meantime. The outside of the tanks are not cleaned.
Total reservoir capacity is about 90,000 gallons.
During the cleaning of the large tank, a check valve was installed to prevent backflow in the water line to the fire hydrant on E. Camano Drive.
When Viewmont's old water main was constructed in 1983, SVWA operated just one well and served less than half of the 84 residences it does now. The new, larger main not only improves service along Viewmont, it provides better water pressure to some residents elsewhere in Sierra Vista since the line is part of our overall distribution system.
The new main also replaced all of SVWA's concrete asbestos pipe, eliminating the risk of an environmental hazard in the event of a line break. A new air relief valve, which vents pressure in the system, and a new flushing station were also installed on the north end of Viewmont as part of the project. Construction was done in the fall of 2023.
Water mains are flushed on the last Tuesday of every month. It's advisable not to do laundry on that day to avoid the potential of back pressure introducing manganese into your washer and potentially discoloring your clothing.
A new electric heater installed in January 2024 keeps the Pump House interior above 50 degrees during the winter. The unit has a fan-only setting that circulates air to help keep the building cool during the summer.
We've historically collected water samples from taps in the the pump house and board members' homes. Best practices recommend obtaining samples from test taps installed on water mainlines. Three test taps were installed in the spring of 2022. The first tap was installed on Janet Ave. The other two taps were placed along Newell Road and Viewmont Place. Total cost: $9,000.
Install a filtration system to remove manganese from well water, which will improve water quality, avoid buildup in the reservoir tanks, and prevent further clogging of water lines and meters.
Upgrade the water main along Sierra Park Lane.
Replace the pump in well 1.
Replace worn pipes and three pumps that distribute water to residences.
