Unfortunately, our Cheam Treatment Works remains out of service. Work has been ongoing throughout the night and will continue until the issue is resolved.

Overnight, we have been able to recover water supplies and have continued to utilise our network to manage storage in the area. Storage levels are very low and we would be grateful for our customers to use water carefully to preserve as much storage in the system as possible.

Some customers may experience low pressure and no supplies throughout parts of today. Bottled water stations remain in place at the following locations:

Bourne Hall in Ewell, KT17 1UG

Upper High Street Car Park KT17 4DU

07:00 17/12/24


We are pleased to confirm that supplies are starting to return to normal.

However, some customers may continue to experience lower pressure or intermittent loss of supply. Our water storage remains low in the area and therefore customers may experience further interruption to their supply tomorrow (17/12/2024).

Our bottled water stations remain open at Upper High Street Car Park, KT17 4DU and Bourne Hall in Ewell, KT17 1UG. When your water returns it may be cloudy, white, or discoloured.

In most cases, this can be cleared by running the cold kitchen tap. Teams are working round the clock to resolve this issue as quickly as possible. We are very sorry for the continued disruption and thank you for your patience.
