Groundwater use in business

The document outlines three business case studies in Cape Town—Woolworths Head Office, Peninsula All-Suite Hotel, and K-way Manufacturers—demonstrating the use of groundwater for toilet flushing, car washing, and air conditioning. It details the technical systems used, the associated installation costs, and the resulting water savings, while promoting GreenCape's support services for businesses seeking water efficiency solutions.

• Woolworths Head Office in Cape Town utilizes five seepage pumps from an underground river, treated with Reverse Osmosis and UV, to supply toilet flushing, car washing, and air conditioning across five buildings, resulting in a 60% reduction in water usage (approximately 1,500 kl/month or 18,000 kl/year) at an installation cost of R1.2 million in 2010.
• The Peninsula All-Suite Hotel in Seapoint uses a wellpoint groundwater system with filtration, chlorination, and rooftop storage for toilet flushing, which reduced municipal water for that purpose by 41% and overall water usage by 10% (~225 kl/month), with an installation cost of R100,000 in April 2016.
• K-way Manufacturers in Ottery employs a wellpoint groundwater system with an aeration system for odours (installed 2010) for toilet flushing, saving 125 kl/month (1,500 kl/year) at a cost of less than R30,000.
