Every day after his morning run, Adam Reutens-Tan washes under a half-full camping shower hooked on the ceiling of his bathroom.

The modified shower, which uses just four litres of water, is one of several ways the Reutens-Tans family conserve water as part of a countrywide push to cut Singapore’s daily consumption by 8% by 2030.

The nation currently uses 141 litres per person each day – about enough for two typical eight-minute U.S. showers, according to Harvard University statistics.
