A well head is the physical structure at the top of the well that connects to the water supply network.
The Council has 104 wells with below-ground well heads and 36 wells with above-ground well heads. All new well heads are built above ground to improve the resilience and safety of the wells and the security of the water supply.
In order for groundwater to be provided without the need for treatment such as chlorination, three criteria must be met:
The Council is upgrading its well heads so they meet the interpretation of the standard required to meet criteria 2 above. Once well heads are secure, temporary chlorination can stop at that pump station.
