HOW A WATER SYSTEM OPERAT ES
Once the well is drilled, cased and gravel packed the
equipment will be installed. First, the submersible pump goes in. The pump is set on drop pipe, which along with many miscellaneous items will deliver the water to the top of the
well. MDC installs the highest quality pumps available from several different manufacturers. As each brand can have different performance curves, we choose the pump that will
best meet the application as determined in the design stage. Occasionally the actual well conditions will warrant resizing the equipment.
A submersible pump works by passing water through a series
of stages, each one consisting of an impeller, diffuser and the bowl in which they are seated. The more stages - the bigger the pump and the farther it will be able to push the water. The
width of the impellers determines pump capacity (gpm). The diameter determines how high the pump can push the water. The horsepower of the motor is determined by the volume of
water and the working pressure of the system.
Once the water is out of the well, it will go to the pressure tank
. The primary function of the pressure tank is the automatic operation of the water system. It does this by using stored air pressure inside a sealed diaphragm that will provide water
under pressure even when the pump is not running. This keeps the pump from turning on and off (cycling) every time water is used.
Again, MDC installs the highest quality tanks available from several manufacturers. Physical
dimensions and vendor availability are generally factors in deciding which brand is used.
