Storage Tank Systems

Bee Cave Drilling sets up storage tank systems a little differently than most other companies. A typical Bee Cave Drilling Well and Storage Tank System (with a steel sleeve wellhead) looks like the diagram below. When the water level in the storage tank drops about a foot from the top, the top float switch triggers the well pump to come on. The well pump pushes water up through the drop pipe to the surface and into the storage tank. The check valve keeps water from flowing back into the well. When the storage tank is full, the top float switch shuts the well pump off.

The booster pump system can be either a standard pressure system with a 20 psi range or a constant pressure system with a 2 psi range. When either the pressure switch or pressure sensor turns on the booster pump, it pulls water from the storage tank to supply the pressure tank… that in turn supplies the house or irrigation system. If the storage tank is ever empty, the bottom float switch will shut off the booster pump to prevent it from overheating.

Most storage tank designs stop here. But the problem is that if your well or well pump has a problem and is not properly filling the storage tank, you would never know (unless you were checking on it regularly) until you were completely out of water. So we install a middle float switch in the tank. This float switch will temporarily shut off the booster pump if the water level in the storage tank falls to that point. When that occurs you can flip a switch to turn the booster system back on and call us to come service the well or well pump. This provides you the reliability that everyone deserves from their water system.


Many of our customers prefer a storage tank system for the following reasons:

    1. Sulfur gas removal: Well water has a lot of dissolved sulfur gas that gives water a “rotten egg” smell. The storage tank will allow the gas to vent off. Just like carbonation in a soft drink, when the water is not under pressure, the gas will “boil” off.
    2. Dependability: The pump in the well will start about 1/20th of the time. Starts are very hard on pumps and should be limited as much as possible. This water well system will double or triple the life of the average pump. Additionally, because the well pump is discharging the water into this “zero-pressure” storage tank, you can use a smaller pump in the well than with a non-storage tank water well. Smaller pumps last longer and cost less to replace.
    3. Backup System: This system is equipped with a backup. If the well pump is unable to fill the tank, the customer is notified, and the reserve water is used until the well can be fixed.
    4. Better pressure and flow: Many water wells do not provide the flow and/or pressure that you desire. The storage tank can fix this problem.
    5. Gravity fed system: If the tank is installed uphill from the home, you will have water even when the power is off.
    6. Sediment removal: The tank allows sediment to fall out of the water without restricting the pressure. The tank also removes iron from the water. The tank can hold several hundred gallons of sediment before it needs to be cleaned. Cleaning is easily done with a siphon hose.
    7. Rainwater supplementation: A water well can be used to supplement your rainwater collection system during extended periods of drought. We will set a float switch in the middle of the tank to establish the minimum volume you want to store in your system at all times. The well will maintain that volume in the storage tank while leaving the volume in the top of the tank available for rainwater harvesting.
    8. Stand Alone Capability: Storage tanks can also be used independently of water wells or rainwater harvesting by having public drinking water delivered in 2000 gallon loads.

Storage Tank Options

2500 Gallon Poly Tank (8’x 8’)

The typical storage tank is a 2500 gallon polytank.
Poly tank wrapped with 1×4 boardsIt can be black or forest green.

“Do it Yourself Timber Tank”

2500 Gallon Poly Tank (7.5’ x 9.5’)

You will not find a thicker, more light and algae resistant poly tank on the market. This thickness allows you to go with a lighter colored tank (like Beige or Mist Green ) if desired.

2650 Gallon Concrete Tank (11’ x 6.3’)and 5550 Gallon Concrete Tank (11’ x 11’)

You can get one with a smooth concrete finish. Or you can get with one this “stone” stamped finish and one of these color templates. They also have a matching pump house.

2500 Gallon Galvanized Steel Tank (7’ x 8.5’)

As you can see, you can get them wrapped in cedar as well. The tank has a spray in liner that protects the metal from rusting for 20 years or so.
