We work around the clock to ensure the water we supply to you is safe.
The majority of water we supply is pumped from underground aquifers. This water is relatively easy to treat as it has already been naturally filtered through chalk or sandstone, and only needs simple treatment and disinfection with chlorine to make it safe to drink.
Water taken from rivers and surface reservoirs requires more treatment stages to ensure the water is of the highest quality.
