Water Pressure


Water pressure in the Ranchos, some residents complain of too much some complain of too little at times. Why?  Well lets discuss your water system and how it works.  The District has six operating wells with one in reserve. The District also operates one water booster station with two pumps.  The District has two water tanks one is located to the south east of the Ranchos and has a 1.5 million gallon storage capacity.  The other tank on the south west side of the Ranchos has a 3.0 million gallon storage capacity.  When you take a look at the tanks check out the height difference on the hills they sit on.

Water from District wells is delivered to residents first then sends the excess water to the storage tanks.  I will first discuss the water system with no wells running and using the gravity flow of the tanks.  The 1.5 million gallon tank delivers water to residents in Pleasantview Subdivision, Silveranch Subdivision, Ranchos Estates, Unit 2 and parts of Dresslerville Rd.  Because of its elevation the higher areas of the District will receive lower pressure when wells are off and the tank is delivering water by gravity.  When someone on Dean Dr. is getting 50 pounds of pressure someone in Pleasantview Dr. could be receiving 80 pounds of pressure because that subdivision is lower in elevation.  It all runs down hill the lower on the hill the faster the water is going to be which translates into higher pressure. 

To remedy the lower pressures, the District in the past has wells that turn on based on lower pressures measured at the well sites.  For instance, if the pressure at Well One on Fairway Dr. gets below 70 pounds, the well will turn on to boost pressure to the whole pressure area.  Now instead of 50 pounds on Dean Drive there could be 65 to 75 pounds of pressure.  But on the other hand the pressure in Pleasantview is now at 90 pounds or greater.  The well will shut off when it reaches a preset level at the tank.  When the storage tank is at 28 ft. of water, the well will shut off as to not overflow the tank.  Then especially in the summer the water system gets into a cycle of turning wells off and on.  The District is now undertaking the task of making pressure more constant by regulating wells and tank levels this winter.

So now the District has another problem. Instead of low pressure we now have high pressure.  Hot water heater valves pop off causing problems.  What to do?  The District recommends that homes that experience constant high pressures talk to a plumber and discuss the addition of a pressure regulator valve to have constant pressure delivered. The District will make every attempt to stabilize pressures this winter.  Please realize that when demand is steady it is much easier to regulate pressure.  Early in the irrigation season pressures can fluctuate greatly because of irregular usage.  Later in the spring and summer, the usage settles out and the pressure becomes fairly constant.  If you have any questions about pressure or when is the best time to water please call the District at 265-2048.
