OVERVIEW
The three-storey hotel is built on former agricultural land and provides 3,000m² of floorspace.

SDS was engaged to minimise the impact of the development’s requirement for the supply and disposal of water on the local environment and existing infrastructure, thereby helping to achieve sustainability objectives through efficient water management.

This has been achieved through the reuse of grey water collected from showers, wash basins and baths for the purpose of flushing all of the property’s WCs.

WHAT THEY DID
This installation represents the introduction of SDS’s uniquely designed grey water on-demand recycling system, which will support the hotel’s water supply, and reduce disposal, by up to 3m³ per day.

SDS Grey Water On Demand Recycling System, a smaller than traditional system, including underground tanks for collected and treated water, was installed due to limited plant space available in the building and to help fulfil sustainability goals.

The system was assembled off site, simplifying installation which largely consisted of incoming and outgoing connections, overflow to drain connections, electrical supply and integration of chemical dosing.

RESULTS
Grey water storage is achieved by means of an underground 4.4m³ tank, which incorporates a submersible pump capable of delivering up to 2m³ per hour. Only the plant items, which take around 5m² of space, and include a 1,000 litre break tank and treated water distribution pump-set, are located above ground.

The system features dry block chlorine dosing, making it safer under COSSH regulations and easier to replenish, store and maintain than the more traditional, liquid chlorine dosing units.

During periods of routine maintenance, servicing, and shutdown, the grey water recycling system can be switched to enable water to be supplied through the mains water feed to the treated water storage tank, bypassing the grey water supply.

A similar rainwater harvesting system has been implemented within multiple other projects supported by SDS, including Plymouth Argyle Football Club (PAFC) stadium, which represents a significant step forward in the club’s Energy and Environmental Plan to achieve net zero carbon emissions by 2050, in addition to plans for ongoing stadium development.

SDS is delighted with the success, helping PAFC earn a top 5 position in the inaugural Sports Positive EFL Rankings of commitment to Sustainability.
