Design and construction of new ‘online’ pumping station and flood storage aquagreen to improve resilience in the Humber region

Flood events in the United Kingdom during the summer of 2007 resulted in a loss of essential services and infrastructure not seen since World War II. Reportedly, over half a million people were left without water or electricity supply, with the estimated cost of the events exceeding £3.2 billion. The subsequent Pitt Review commissioned by […]

South Ferriby lies on the south bank of the Humber Estuary, approximately 12 miles from Hull. During a tidal surge in December 2013, the existing flood embankments were inundated causing £50m worth of damage by flooding 129 properties, the CEMEX cement plant, 500 hectares of agricultural land and the A1077. Residents were left fearing for […]

Bentley Ings Pumping Station is located within the River Don flood corridor, north-east of Doncaster and protects over 3,000 residential and 172 commercial properties from fluvial risk. The pumping station was constructed in 1942 and failed in 2007 during an extreme River Don flood event, resulting in flooding to over 1,000 properties. The aim of […]

The Foss Barrier and associated pumping station is a vital asset in the City of York’s flood defences and was constructed in the 1980s in response to severe flooding five years earlier. In flood conditions, a mechanical gate can be lowered to stop rising waters in the River Ouse from flowing back up into the […]

In December 2015, the most severe floods in a generation hit the City of York. As water levels rose to the highest recorded on the River Foss, they entered the main control building at the Foss Barrier, which forms an important part of the city’s flood defences, rendering the facility inoperable. The Foss Barrier and […]

Three of Southern Water’s underground storm tanks next to the historical Fort Cumberland have played a crucial part in helping to prevent homes in Portsmouth from sewage flooding during stormy weather. Although redundant, the old sea defences protecting the tanks needed replacing and strengthening, and ongoing maintenance is essential to preventing their contents polluting the […]

Built in 1987, the Foss Barrier forms an important part of the flood defences for the city of York. When a flood event is predicted, a mechanical gate can be closed to prevent rising waters in the River Ouse from backing up into the River Foss, preventing flooding to a large part of the city. […]
