Sustainable heat from sewage projects
IN the first project of its kind, Campbeltown’s Aqualibrium Leisure Centre and swimming pool, operated by Argyll & Bute Council, will be heated by waste water. The £1m project will meet 95 per cent of
the facility’s heating needs and use just 25 per cent of the energy it currently takes to heat it with gas. Intercepting waste water from Scottish
Water’s adjacent Kinloch Park Pumping Station, the technology will extract the naturally occurring residual heat, amplify it and transfer it to the clean water network to provide heating to the centre’s 25m pool, fitness suite, steam room, sauna and library. The new heat recovery system will be
integrated into the council’s existing heating infrastructure. Expected to complete by November,
Aqualibrium is the first project to be delivered by the new joint venture between Scottish Water Horizons, a subsidiary of Scottish Water, and sustainable energy firm SHARC Energy Systems. Scottish Water treats 945 million litres of waste water every day; the joint venture aims to expand and accelerate waste water heat recovery systems across the country. The Campbeltown project is being
funded by Scottish Water Horizons and the Scottish Government’s Low Carbon Infrastructure Transition Programme. The Scottish Government’s new Energy Strategy aims to supply half of all energy for heat, transport and electricity from renewable sources by 2030.
Slashing energy costs with CHP
CHINA Fleet County Club in Saltash, Cornwall is on track to save £55,000 a year in energy costs. Set in 180 acres of countryside, China Fleet
offers a health club, swimming pool, 18 hole golf course, spa, self-catering apartments, restaurants and conference and wedding facilities. With energy usage rising year on year, the
venue partnered with ZLC Energy to dramatically reduce its energy costs. In 2016, the China Fleet used 1,790,080 kW/h of electricity at a cost of £208,723 and 2,191,200kW/h of gas costing £37,740. An assessment identified Combined Heat
and Power (CHP) as the most favourable option for the facility. “The club has got a very high electricity and heating demand on gas and the CHP was able

to deliver high levels of saving for the club,” says Matthew Shepherd, managing director of ZLC Energy. Installed this March without any disruption
to services, the system detects the heat requirements of the building and uses a gas- powered feed to create electricity for use on site. The excess heat generated from producing the electricity is captured and used to heat the swimming pool. The system is expected to deliver annual
savings of £55,000 for the club. Payback on the system is 2.7 years and the estimate return on investment is 37 per cent.
