My water supply

We collect our water from deep holes, called 'boreholes', which collect water from natural underground stores, known as aquifers. Once this water is collected, it is cleaned, treated and sent to your home.

On average, we get 585mm of rainfall each year in Cambridge. We need half of this to fall during the winter, to refill the underground water sources and provide water to streams and rivers, as well as for drinking water.
We manage the water we take from the aquifers, to make sure that you do not go short of water, and that we do not adversely impact the environment.

This water undergoes extensive treatment, to ensure it meets strict drinking water standards. Once the water has been cleaned, it's stored in huge, covered storage tanks called 'service reservoirs'.

The service reservoirs tend to be on higher ground. Water is pumped up to the service reservoirs, which ensures there's enough pressure to reach the properties that the reservoir serves.

Water mains are then used to carry this water from service reservoirs to the roads outside your home.

From here, a water supply pipe connects the water main to your property, flowing into your house and out of your tap.
