Extensive surface water flooding took place in Badger Hill and the Leeman Road area last year.
Now a official report into both incidents cast new light on the causes of the problems.
Hull Road
In the Badger Hill area, “flooding occurred due to an intense rain storm on 10 June 2012, affecting Hull Road and the Badger Hill Estate.
Hull Road was closed to traffic for 5 hours, 19 properties flooded internally, and about 40 suffered flooding to gardens and external areas”.
Yorkshire Water was found not to have maintained some of its systems.
Flooding in the Leeman Road area occurred in September and November 2012.
“Salisbury Road and Salisbury Terrace, a major route into the City, had to be closed to traffic as the risk of flood water inundating properties was further aggravated by waves from vehicles.
Temporary pumping eventually reduced the level throughout the area and internal flooding of properties was avoided by sandbagging.
The area is defended against overland flow from the river by an earth embankment maintained by the EA.
The sewerage system is equipped with penstocks, which isolate the river from it, and a pumping station which pumps flows from the defended area to the downstream sewer outside it.
This is the responsibility of Yorkshire Water”.
NB. At the time the Council Leader blamed the Environment Agency for the problems.
The official investigation report reveals that
“some of the penstocks were not fully closed or leaking and in one case open. It was also found that one of the pumps was not correctly seated on its base and was therefore ineffective.
As a result of the investigation Yorkshire Water has reviewed its maintenance and operational procedures to ensure future resilience during flood events.
It is also liaising with the EA to ensure that the improved defences, which will be constructed this year, will not be compromised by shortcomings in the sewerage system”.
