Limberg answers questions over City of Cape Town’s water tariffs

Cape Town - This week, the City of Cape Town revealed that the total capacity of dams supplying the Cape Town metro has increased to 96,4% between 7 August and 13 September 2020.

This is an 0,8% rise from the previous week.

At the same time last year, dam levels were at 81,9%.

The increasing dam levels over recent weeks, due to rainfall coupled with the decrease in water demand, has generated questions from residents about water tariffs.

Mayco Member for Water and Waste Services, Xanthea Limberg issued a statement, with responses to questions she is frequently asked:

1. Now that the dam levels are increasing, can the City reduce the water tariffs?

The City does not budget for a profit from the sale of water and seeks to keep costs of service delivery as low as possible. The fixed/variable tariff model that the City uses is in place throughout South African municipalities due to the increased water security it allows.

A reduction in tariffs will be dependent on an increase in consumption. While the dams are the fullest they have been since 2014, consumption is still significantly lower than before. Currently, the City is selling approximately 30% less water than before the drought, but is facing additional costs that come with increasing our resilience through additional water resources. It is important that the City covers its costs to ensure that the maintenance and augmentation programmes can be carried out. Should the amount of water we are selling significantly increase, this will be factored into the tariffs, but given the uncertain impact of climate change, it may not be wise to actively encourage such an approach at this stage.

The City is currently on Level 1 tariffs, which is the second lowest tariff level and it will need to consider whether to move to the lowest tariff, being the no restriction, water-wise tariff. The lowest tariff is not tied to a restriction level. Importantly, that decision is based on how much water is likely to be sold so that water services can still be paid for, rather than how much water is in the dams. Thus the decision on a possible change to the restriction level needs to take place first.

2. What is the fixed charge and why do we need to pay a fixed basic charge when the dam levels are increasing?

  • The fixed basic charge is not a ‘drought levy’. A proposed ‘drought levy’ was considered at one point during the drought, but it was never approved and therefore not implemented.
  • The fixed basic charge is not ‘an additional tariff’ but it forms part of the total water tariff structure.

The total water tariff (which includes a usage portion and a fixed charge) covers the cost of purchasing the bulk water, the treatment of the water, the delivery of the water to homes and businesses and the maintenance of all the infrastructure to deliver this service.

The fixed basic charge portion of the tariff was introduced to ensure financial sustainability to provide the service irrespective of the level of consumption and to ensure a fairer payment of the costs by all customers.

Prior to the drought, the tariff was based on a consumptive portion only. The drought revealed that if consumption dropped significantly (i.e. beyond levels we could have expected before the drought), it could also affect our long-term future by taking away resources for necessary maintenance of the water service.

As such, the City changed the tariff structure so that a fixed portion of the revenue necessary to run the system responsibly is guaranteed no matter how much water residents consume. This is a funding model that is used at all South African municipalities.

The consumptive tariff portion is lower than it would be if there was no fixed portion.

3. Do other municipalities have fixed charges?

Yes, this fixed/variable tariff model is in place throughout South African municipalities to guarantee a fixed and stable income to fund the water service as it increases water security.

4. Why don’t we get 6kl free water per month per household anymore?

The free 6Kl of water per month for every household across the board was largely made possible by properties consuming high volumes of water, in the upper steps of the tariff which are no longer available. It was neither possible nor sustainable to continue delivering 6Kl of potable (drinking) water at no cost to every household in the city.

Residents who are registered as indigent continue to receive an allocation of free water.
