GreenCape have been working with companies to showcase example of alternative and reduced water use in their respective business sectors. City Sightseeing South Africa are an example of a company in the tourism sector that have done this as they have secured their own water supply by commissioning a desalination plant and water efficient technologies.
City Sightseeing South Africa is a tourism service travel operator which offers guided tours of main city attractions by foot, bus or boat. The ongoing drought has presented them with a challenging environment in which to sustain operations.
City Sightseeing have invested in a number of water-efficient measures including installing water meters to track water use, retrofitting ablution facilities with tap aerators and lowflow shower heads, providing buckets in showers for grey water collection, putting volume-displacing objects into toilet cisterns, and harvesting air conditioner condensate for onsite cleaning, washing of buses, and for handwashing. City Sightseeing also invested in a desalination plant capable of producing potable water, making them independent of the municipal water grid. As a result, they reduced water consumption from 8 to 0.02 kilolitres per day.
