It is widely known that a significant proportion of East Anglia relies for its existence on the effective operation of widespread land drainage networks. Without these networks much of the region would not be able to function in the way that it does and the population would be hard pressed to continue their lifestyles in the way they do in the modern world due to the high ground water levels.
Much of the drainage to keep ground water levels in check is achieved using local pumping stations that take water from the land drainage network and pump it into local rivers and drainage channels that remove the water off the land and out to sea so keeping the local area from flooding. These pumping stations are under the control of the Internal Drainage Boards (IDB’s).
However, when undertaking rehabilitation of a pumping station at a site near Kings Lynn, a reverse syphon carrying water from the pump station to the main drainage channels that fed the local estuary, was found to have failed and there were fears that water normally carried by the syphon away from its local pumping station would cause problems.
The failure of the syphon meant that water from the pumping station was not, as would normally be the case, all removed from the network but that it was being returned back into and potentially undermining the pumping station due to leakage in the syphon. This was also causing the river bank near the pumping station to erode. It was causing problems in the pump station as water was recycling, meaning the pump station was working significantly harder than it should, incurring extra cost and potentially could lead to significant flooding problems for the area.Read More
