Water Deposits and Water Tanks

Here in Andalusia the mains water supply can often be cut for several days and where the water pressure can fall to a mere trickle.

Water deposits or water tanks - as they are sometimes called - are a vital part of managing your water requirements in your home.

Water deposit and tank application parameters include the general design of the tank, its materials of construction, as well as the following: 

  • Location of the water tank (above ground vs. below ground)

  • Volume of water the tank will need to hold

  • What the water will be used for (drinking vs. irrigation)

  • Temperature of area where water will be stored

  • Pressure requirements (domestic pressure range 35-60 PSI)

  • Methods by which water is delivered into and extracted from the water tank

  • Design considerations allowing water tanks to survive seismic movement and natural land movement

  • Back flow prevention

  • Chemical injection for bacteria and virus controls

A frequently asked question is whether to have the tank below or above ground?

Whilst the cost difference can be substantial, which will include excavating the ground, laying a reinforced concrete base to prevent slippage and then backfilling with aggregates or sand, Below Ground is invariably the correct answer. Not only for the aesthetics, as the tank or deposit can be substantial in proportion and look very commercial and out-of-place, the main reason is to do with the summer heat, with temperatures getting to the high 30 degrees centigrade. The build up of harmful bacteria at these high temperatures should be an area for concern. There needs also to be a constant movement of water in the tank as it is used and topped up by daily usage. The tank or deposit should not just be a Holding Tank for emergencies, when the water supply is cut off.

As water tanks and deposits are essential for living in the countryside in Spain, it’s important that they are installed correctly. Why not talk to us and have our builders install your new tank or upgrading your existing system.
