Hello, new to the forum so feel free to redirect me if this topic is not proper for this forum. I am a volunteer on the water committee of a community water system. The system provides potable water for 30 residences and a possible 30 more. We cover a full section of land (1mi x 1mi), have 3 well yards and 4 producing wells. Our area is hilly so the yards are separated by up to 60' in elevation and 1500 yards in piping. Most of our main line pipe is 6" with some 3-4". We have 48,000 of storage. The system began in 1975 with 1 home and 1 well and has grown since so some of our buried pipe sizing is iffy. Our yards are identified as East, West and North.
We just added the 3rd yard and well (North). It is the lowest in elevation by 50' but the highest producer by 5x (30gpm+) over the other wells. Since we are in the high desert rock three of our wells produce less than 4gpm - our members are conservative water consumers. Due to the production we want the new well and pressure system to provide the majority of the water. All yards have 7,000gal pressure tanks certified to 250psi. Our to older yards have mercoid pressure switches and are adjusted to 95psi ON and 115psi OFF. This has proven to provide most residences with 45-55psi depending on line drop and elevation change.
The new yard has a digital (dwyer) pressure switch and is set at 118psi ON and 130psi OFF. At these settings the new yard is not contributing to the water consumption. Faced with our elevations and homeowner need of 45psi min at each home how you you folks tune this system? Just bump the North yard pressure? Other ideas?
