Borehole filtration system for a new build in Halifax

This customer has recently had a borehole drilled and needed to know what contaminants were in the water. The only way to find out this information, for certain, is to have the water sampled. As our engineers are UKAS Accredited, the customer asked if we could attend site, take samples and submit to a UKAS accredited laboratory for testing.

The results of the analysis showed elevated levels of sediment, iron and manganese which were all outside of regulations set by the DWI and shown in the Private Water Supply Regulations. Bacteria, although in relatively small numbers, was also found in the supply. Regulations state that all private water supplies should be free from bacteria. To remove the bacteria we installed a UV along with a prefilter.

A prefilter is always installed before a UV, usually with a 5 micron filter element, to remove sediment from the water prior to it passing through the UV chamber. This ensures all water is treated by the UV light.

Many barn conversions, barn renovations and new builds do not have access to mains water so a private water supply is the only, financially viable, option.

If you require assistance with your private water supply, whether it be for an existing property or a new build, please get in touch.


Hard Water

Any water supply that has a high mineral content, may be classed as hard water. The most common minerals that cause hard water are calcium and magnesium. These minerals are picked up by water, as it passes through (typically) limestone rocks, on its way down into the water table.

Existing Systems

At Prosep Filter Services we have taken on many Water Treatment Systems installed by other companies like ourselves. We are always happy to work with new customers. 

Iron & Manganese Reduction

Prosep Filter Services offer various sizes of systems to remove iron and manganese from your private water supply. We have technical experts on hand to help resolve any problems you may have with your borehole or spring water supply.

pH Correction

Water in which the pH is below 7 is acidic. Acidic water accelerates corrosion in pipe work, It can also cause staining on fittings in baths, sinks and other appliances. Acidic water can leave a distinctive ‘metallic’ taste when drunk.


The UV-PRO range of ultra violet sterilisers, by Prosep Filter Services, are versatile units for domestic applications designed to kill waterborne bacteria using the proven method of exposure to ultra violet light.
