No obvious group to place this query For a low lying road near me if you monitor the water level under the grill of drains in that road this last week of high tides it goes up and down at the high tides. In fact for similar weeks but low atmospheric pressure , so the sea water level can rise much further, then local flooding starts from water flowing up out of these drains. So defeating the 0.5 metre or so of elevated ground beteween this road and the tidal river. Where do I find out about whether this is normal or failure of flap valves at drain outflows to the river. ? Responsibility of local council,county council, highways authority, harbour board, environment agency or water/sewage authority ? As I cannot see any obvious such hinged flap valves anywhere nearby and as there seems to be no lag between rising river water and rising drain trap water I would have thought it was not due to ground water seepage.
