Earlier research has underlined that household end-uses form building blocks of the residential water demand pattern. Numerous end-use studies have been presented in the past, but none have reported on shower end-uses at Universities in South Africa. This research focuses on shower water use, as part of the first detailed end-use field study conducted in South Africa. An extensive desktop study was conducted regarding South African end-uses, focusing on shower use. Shower flow rate was physically measured under different conditions, while actual shower duration for the same showers was derived from water temperatures recorded over two periods of 5 days each, at 1 min frequency. The changes in temperature were used to estimate actual shower duration and event start times. The total shower event volume was stochastically determined by using Monte Carlo analysis. The average shower duration of the 759 shower events identified as part of this study was 9 min and 33 sec, with a flow rate of 8.7 L/min. The average shower event volume was 83 L/event.
