Cape Town’s Quest for Water Security
Published on by Robert Brears, Founder of Our Future Water, Young Water Leaders, Mitidaption & Author (Springer Nature, Wiley) in Government
The City of Cape Town is warning its residents that their water consumption is too high and that they need to reduce their water use to winter levels.
This is in response to a drought in the Western Cape that has seen dam levels in the province drop to 55%: down 10% compared to last year.
Cape Town’s quest for water security
Because Cape Town is situated in a water-scarce region, the city imposes water restrictions on a permanent basis, with the level of water restrictions dependent on dam storage levels. Cape Town has three levels of water restrictions:
- Level 1 (10% water savings): Normally in place
- Level 2 (20% water savings): Applicable when dam levels are lower than the norm
- Level 3 (30% water savings): Applicable when dam levels are critically low
Cape Town's quest for water security
Drought restrictions
Since 1 November, Cape Town has been under Level 3 (30% water savings) which restricts water usage activities including the prohibition of residents using sprinkler systems, watering their gardens, and washing their cars with hosepipes with municipality-supplied drinking water.
Cape Town pricing its way to water security
To reduce water consumption further, Cape Town will, from 1 December 2016 until further notice, charge all residential, commercial and industrial water uses Level 3 (30% savings) tariffs. For domestic water users, the first 6,000 liters remains free, but the next block rates will increase significantly (see table 1 below). Meanwhile, commercial and industrial waters, who are normally charged R18.77 including VAT per thousand liters (under Level 1 water savings), will now be paying the Level 3 charge of R25.35 per thousand liters (table 2).
Table 1. Cape Town’s residential water tariffs
Water 2016/17 (domestic full) Steps | Unit* | Level 1 (10% reduction) Normal tariffs Rands (incl VAT) | Level 2 (20% reduction) During level 2 restrictions Rands (incl VAT) | Level 3 (30% reduction) During level 3 restrictions Rands (incl VAT) |
Step 1 (>0 ≤ 6kl) | /kl | R 0.00 | R 0.00 | R 0.00 |
Step 2 (>6 ≤ 10.5kl) | /kl | R 14.89 | R 15.68 | R 16.54 |
Step 3 (>10.5 ≤ 20kl) | /kl | R 17.41 | R 20.02 | R 23.54 |
Step 4 (>20 ≤ 35kl) | /kl | R 25.80 | R 32.65 | R 40.96 |
Step 5 (>35 ≤ 50kl) | /kl | R 31.86 | R 48.93 | R 66.41 |
Step 6 (>50kl) | /kl | R 42.03 | R 93.39 | R 200.16 |
*1kl is a thousand liters

Revenue-neutral tariffs
While water consumption will decrease, the tariff has been designed to be revenue-neutral when applied to the current consumption levels. The proposed increases are designed to recover the loss in revenue due to the reduction in billed consumption, so no operational consequences are expected.
The take-out
During times of drought, water utilities can implement revenue-neutral pricing strategies that encourage conservation.
