Water quality

Our aim is to maintain the air, land and water in the borough to the highest possible quality. This is done by monitoring the environment, controlling the release of pollution, giving advice and by taking action against those who pollute.

Water in Tower Hamlets is important to us all. Of course, we need it to drink, but we also use it for safe recreation. A large area of our borough borders the river Thames, and there are many canals, docks and other inland waterways.

The Private Water Supplies (England) Regulations 2016 came into force on 27 June 2016 and requires the council to check the quality of private water supplies.

These regulations permit London Borough of Tower Hamlets to recover costs associated with providing particular services to private supply owners/operators such as carrying out risk assessments, investigations and taking and analysing samples.
