Drains in Windsor: worth knowing

Thames Water provides sewerage for much of the South East, including homes that get their drinking water from another company. If a blockage is in a shared or public sewer rather than your own pipes, the water company may deal with it.

At the 2021 Census, 20.6% of households in Royal Borough of Windsor and Maidenhead rented privately, up from 16.2% in 2011, and 66.2% owned their home. If you rent, your landlord is responsible for repairing pipes and drains.
