It is not always a requirement, but it will depend on the water available and your water usage. In normal usage situations where the borehole has adequate supply, the submersible borehole pump will pump straight to a 300 litre pressure tank and then straight around your water system. If the available water is not enough to keep up with your usage requirements or you have excessive usage requirements all at one time, then a storage tank would be a good option. That way you will never run short of water when you need it.

In most circumstances, storage tanks would usually be in the 1 to 5 tonne range, constructed of bonded nylon, and may be placed above ground, preferably under cover or shielded from frost. These tanks are lightweight, easy to move and manoeuvre and last very many years – maintenance free, and resist harmful solar UV radiation.

What borehole pump you will need depends on a few factors. How deep your borehole or well is and what volumes of water which you expect to need and the amount of lift which is required to bring that water to the surface. If your well or bore hole is very deep, you will need a more powerful pump, even if your requirements are modest as it takes a lot of energy to lift water vertically. This type of pump is for getting water out of the ground, often from great depths and delivering it to the surface.
Depending on the amount of water to be moved and the distances involved, single or three phase pumps may be used. In general for most cases, single phase pumps ranging from 750 watt to 2 Kw are all that is required.

The answer to this question depends on the results of a water analysis tests. If you are using a storage tank then we would always recommend a simple ultra violet filter at the point of use if you intend to drink the water.
However, if you are pumping directly to an irrigation system for example, usually no filtration is required.
If you are supplying the general public, a caravan park for example, then a full filtration and UV system should always be installed to suit your water analysis test results.
Other forms of filtration might be needed if your water has high levels of iron, manganese, lead, or any other metals, or if your water is excessively hard or soft. As a rule, the water is usually pure enough to drink as it is!

A borehole should last several generations at least. Boreholes are lined with tough plastic liners to the bottom which allow water to flow into the borehole and prevent the bore from collapsing. These liners are virtually indestructible so it’s feasible that a modern lined borehole could last hundreds of years or more.
