Question to the Department for Environment, Food and Rural Affairs:
To ask the Secretary of State for Environment, Food and Rural Affairs, what information his Department holds on the number and proportion of homes that use a (a) combined and (b) segregated sewerage system in Devon.
Defra does not hold the specific information on sewerage operations in different regions. It is the responsibility of the sewerage undertaker to manage its own operation, in this case South West Water.
