Reducing water use in offices
Summary
JG Afrika's Cape Town office reduced its water consumption by 67% between 2011 and 2017 through a phased approach of demand reduction and efficiency upgrades. Initial steps in 2012 and 2013, including reducing irrigation and installing waterless urinals, led to a 24% reduction in average annual water consumption. In response to the Western Cape drought in 2016 and 2017, the firm turned off irrigation entirely, implemented weekly consumption logging, and installed hold-flush toilets, low-flow tap aerators, and low-flow shower heads. These technical interventions were supported by staff education and awareness campaigns. To further increase resilience, the firm installed two 10,000-litre rainwater tanks. The total capital investment for these measures was R13,100, resulting in annual water savings of 727 kilolitres in 2017 and cumulative annual savings of R33,424 since 2011.
