Reasons for Private Water Supply Filtration
If your property is served by a private water supply i.e., spring water, well water or from a borehole, it is highly recommended that all water used for domestic purposes is treated to ensure that it is safe and wholesome. The quality of water from a private water supply can vary greatly and may contain harmful pathogens and parameters associated with serious illness. It is therefore important to understand the quality of the supply and contamination risks such as from grazing animals.
Private supply water should be treated with an appropriate system. This may just be a simple filtration and disinfection system (usually by UV lamp) that will turn unfiltered water into potable water (water that meets the required safety standards for drinking). Additional treatments may however be required to reduce metals, prevent corrosion and nitrate removal if necessary.

Private water supply testing
Through our UKAS certified laboratory we can analyse your water supply for parameters of interest including microbiological and chemical testing, specify a robust treatment system and if required, a management service plan to suit.
Existing Private Water Supplies
GCW can also review existing systems and check that the treatment fitted is functioning efficiently and is correctly specified for the relevant parameters.
The associated infrastructure such as pumps, pressurisation equipment and storage tanks can also often be modernised with more efficient products to increase reliability and to ensure consistency and stability of pressure throughout the property.
