In addition to supplying drinking water, many these are nature reserves and are used for recreation. GENeco Wessex Water's GENeco subsidiary, established in 2009, operates sewage treatment works. It recycles waste, produces renewable energy and provides the agricultural industry with fertiliser. In summer 2010, GENeco launched the Bio-Bug, a modified VW Beetle that runs on bio-gas generated from waste treated at sewage treatment works. Waste flushed down the toilets of just 70 homes in Bristol is enough to power the Bio-Bug for a year, based on an annual mileage of 10,000 miles. In November 2014, the UK's first bus powered entirely by human and food waste went into service between Bristol and Bath, run by tour operator Bath Bus Company. Since 2019, biomethane powers buses on one of Bristol's MetroBus routes. The gas is produced at the company's "bioresources and renewable energy park" in Avonmouth, which is run by GENeco.
