Rain Water Harvesting For Salisbury Cathedral

Salisbury Cathedral
Salisbury Cathedral

Aquatech Pressmain supply rain water harvesting system for the new visitors centre “Little Paradise” at Salisbury Cathedral.

Little Paradise is first permanent new build at Salisbury Cathedral since the fifteenth century. A purpose designed building providing new toilet facilities supplied via the rain water harvesting unit, it marks a significant milestone for the cathedral as it looks to deliver a long term programme of improved facilities for its congregation and visitors to the Cathedral and surrounding Close.

The building combines timber, glass and stone to blend perfectly with the historic environment around it, and has minimal impact on the fabric. It replaces temporary toilets, enhancing the appearance of the south side of the building and simultaneously returning the south cloister, which had become an over-flow storage area, to its original beautiful and reflective space.   The project has been made possible through donations, legacies and pledges from the Friends of Salisbury Cathedral and other generous supporters.

Portman Mews pump station

This pump station is a foul water facility located in the basement. The well had alarmed over the previous weekend in a highly contaminated state with massive amounts of accumulated fat which had solidified onto the control floats and thus made them too heavy to tip.

The floats were cleaned of fat and returned to the well. Standard checks for fully auto operation were carried out together with load checks’ all parameters and operations found to be normal. The fat accumulation in this well was a direct consequence of the effluent containing a large volume of waste from a restaurant located in the building. The cooking style relies greatly on a product that is essentially clarified butter and the residues from the cooking utensils, plates etc. will find their way into the waste stream regardless of any recycling mechanisms that the restaurant uses for waste oil.

The well required jet washed and then emptying by vacuum tanker. This operation would then need to be carried out at a regular frequency to keep the condition of the well in an acceptable condition.
