Main Drainage from A404 blocked

Highway Draining Issues @ Whielden Gate, HP7 0NE. Whielden Gate is effectively a no through road which has 5 properties located in the road. From the access point off Whielden Lane adjacent to the junction of the A4004, Whielden Gate falls downhill until it levels out at the base opposite Whielden Gate House.

Hopefully, this potential disaster can be averted and whilst we are insured, the fact remains that if ask
