Reservoir lining protection provided for two new reservoirs in Ely, Cambridgeshire

A recent reservoir lining protection project utilised 162,000 m2 of Terrex SNW40UV geotextile to provide puncture resistance. The two new reservoirs are to support one of the world’s most advanced greenhouse projects near Ely in Cambridgeshire. The £86 million project, led by AGR Renewables, utilises one 5.5 acre reservoir to harvest rainwater from the adjacent 55 acre greenhouse before returning it to irrigate the crops.

The larger 22 acre reservoir (equivalent to 12 football pitches) is utilised to warm the greenhouse via a heat exchange system, with open loop heat pumps transferring energy from the nearby reservoir to the greenhouses. The greenhouse is among the largest ever constructed in the UK, with a footprint of over 22Ha to enable tomatoes and cucumbers to be grown all year-round. The project increases the volume of UK grown vegetables, thereby reducing food mileage and helping to support decarbonisation in the agriculture sector. The full case study can be read here
