HIGH-TECH WATER REUSE IN KENSINGTON
PIONEERING ON-DEMAND GREYWATER RECYCLING SYSTEM IS ONE THE FIRST INSTALLATIONS OF THE TECHNOLOGY IN THE UK
An innovative , smart water-recycling technology has been installed as part of the prestigious 80 Holland Park development by CPC Group , located in one of London ’ s most exclusive residential neighbourhoods .
Meeting high standards of sustainability was a priority at 80 Holland Park , a stunning new-build development of 25 individuallydesigned residences within the Holland Park Estate , Kensington .
To meet planning and building control regulations , mains water demand was required to stay below a strict 110 litres daily allocation for each resident of the penthouses , duplex ‘ town houses ’ and loft style apartments .
RECYCLED WATER ON DEMAND
London-based consulting engineers chapmanbdsp specified a pioneering new on-demand greywater recycling technology from water management systems specialist SDS , in one of the first installations of the technology in the UK .
The bespoke system enables the waste water from baths and showers to be collected , treated in the digitally-controlled greywater system , and then reused for toilet flushing throughout the building .
By reusing water , the overall mains demand was calculated to reduce by at least 15 % to an average of 90 litres per person per
day , a very low level and significantly below the current national average of 140 litres .
“ In keeping with 80 Holland Park ’ s carefully-considered and individually-designed apartments , the bathroom fittings are of a very high specification ,” explains Dave Honey , principle public health engineer with chapmanbdsp .
“ Planning conditions required the development to comply with Building Regulations Part G and the water efficiency criteria for new dwellings , normally 125 litres per person per day , but reduced further to 110 litres per person by a planning condition .”
GROUNDBREAKING GREYWATER REUSE
The groundbreaking SDS Greywater on Demand system could fit in the building ’ s plant room much more easily than conventional membrane bioreactor ( MBR ) treatment , which would have been difficult to design around the constraints of the building .
Waste water is collected from 27 outlets around the building via a dedicated network of pipes that are routed to the basement plant room . It is treated in the SDS Greywater on Demand system with state-of-the-art ultrafiltration technology and is then used to provide for flushing of 88 WCs throughout the development . The estimated greywater yield per day is just over 3,000 litres when the development is fully occupied .
When combined with SDS ’ s smart SYMBiotIC TM cloud-based data monitoring and control , the system can be configured to provide real-time performance measures , condition monitoring and regular water-saving reports .
