Fall 2012 Newsletter
Welcome to Vista Vu Water Users Association's newsletter. Our purpose is to keep you informed about important activities and projects that your Board of Trustees is undertaking on your behalf.
**Work Party Saturday Sept. 8th.**
Starting at 8:30 a.m., we'll be installing two orifice plates and a meter box to serve Truitt and Oestreich. Bring shovels and sunscreen. Vista Vue will provide lunch and bottled water.
Irrigation Improvements Work Flawlessly
Halfway through the second year since being installed, our VFD controlling our main 250 hp pump is again saving money and preventing headaches for the Board members who run it. We have produced a checklist for start-up and shut-down that we'll be using to train people to operate the system. As a start, all Board members will be trained so that we have some staffing redundancy.
But, sometimes there are several Board members out of town at the same time. What would happen if the irrigation system shut down? Who would restart it? We need at least four Association members to learn how the system works.
Last Domestic Water Meter to Be Installed
Over the summer meters were installed on the lines serving the Elsbree, Stenberg, Vanderstoep, Shove and Marsh residences. Oestreich's will go in on Sept. 8th. and that will complete the metering required by the Dept. of Health by 2017.
Arsenic Removal System Improvements
After some research and discussions with the arsenic treatment units manufacturer and our engineer, your Board identified the two most effective measures we could take to correct problems we've had with the units: Chlorination to get better adsorption of arsenic on to the media, and blending treated and untreated water to stretch out the life of the media. The Dept. of Health has approved these remedies and our engineer has prepared drawings of the necessary plumbing changes.
As we explained in our Summer Newsletter, chlorine changes one form of arsenic to another kind that is more readily adsorbed by the media in the arsenic treatment units. Blending raw well water with treated water coming out of the adsorption units will result in Vista Vue residents having a water supply that will meet or surpass EPA's maximum allowable arsenic concentration of 10 parts per billion (ppb). Because less water will be treated the media will last longer.
Other Domestic System Improvements
While the plumbing for the blending process is underway we will take advantage of the opportunity to make other changes in the domestic pump-house.
Back-Flush Isolation Valve
We will install an automatic valve to prevent excessive volumes of treated water passed through the tanks during periodic back-flushing cycles. The equipment manufacturer has given us the electric valve plus installation cost to compensate us for their error.
In early summer we had an instance where, following a power outage, the well-pump motor did not come on when commanded by the floats in the reservoirs. As a result the reservoirs drained and we lost water pressure in the system. It turned out that the VFD which controls the motor must be manually reset after a power outage.
To prevent a recurrence Butch Electric will install an alarm system that would be triggered by a flow switch in the incoming well-water line. The alarm will also be activated if the pump-house sump pumps turn on due to a leak. A horn will sound and lights will flash to alert neighbors of an emergency.
