How to save: In the shower
Q: How can I tell if my existing showerhead is already energy- and water-efficient?
A: 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 in the bucket with a measuring jug. If there are more than 2 litres then your showerhead is inefficient. A good, modern product will save water and electricity without compromising your shower experience, and the saving usually pays back the investment within a few weeks or months.
Q: How will switching to a low-flow, energy-efficient showerhead affect my shower experience?
A: Energy- and water-saving showerheads usually deliver the same shower sensation as conventional showerheads and your shower experience should not be affected (unless you already have a problem with low water pressure). Flow restrictors tend to be problematic in houses with low water pressure, so if pressure is low rather use an aerated showerhead. Eskom recommends that the showerhead flow-rate should not be less than nine litres per minute to ensure that your shower experience is not compromised. The minimum pressure on your geyser should be more than one bar.
