Install an efficient shower head

Cape Town water bylaws limit shower flow rates to no more than 10 litres per minute. To test this at home, hold a bucket under the showerhead for 12 seconds. Measure the amount of water within the bucket with a measuring jug. If there is more than 2 litres then your showerhead is inefficient. A good, modern product will save both water and electricity without compromising your shower experience, and the saving usually pays back the investment within a few weeks or months.
