WHAT IS A VOLUME BASED SEWAGE DISPOSAL CHARGE?

It is a method of charging for the use of the sewage disposal service which reflects the degree to which a particular customer uses the service. In this respect it is similar to the charges levied for the supply of potable water and for electricity where the usage is metered.

However, it would be unduly expensive and not practical to measure the volume of sewage which leaves an individual premises. Rather the sewage volume can be based on the amount of water provided to the premises.

WHAT IS SEWAGE?

Sewage includes all water which is used by a household and discharged to the sewerage system. It includes water used in toilets, showers, baths, sinks, basins, washing machines, dishwashers and the backwash from swimming pools.

HOW IS THE VOLUME OF SEWAGE DETERMINED FROM MY WATER USAGE?

The volume of sewage discharged to sewer is determined as a fraction (or percentage) of the water usage at a premises.

For an average one or two storey house on a typical plot,  if the water usage is low, the majority of water generally is used for toilet flushing , showers, baths , sinks etc , all of which will discharge to sewer. As the volume of water  usage increases , more and more water is generally used for purposes such as watering gardens , car washing etc and other uses where the resulting “waste water “ is not discharged to the sewerage system.

However, for a unit in a block of flats , the majority of water usage in a flat results in a discharge to sewer.

Similarly the use of water for non-domestic purposes ( ie at commercial and industrial premises ) also generally results in a significant fraction of the water usage being discharged to sewer.

HOW MUCH WILL I PAY IN SEWAGE DISPOSAL CHARGES?

There are separate sets of charges for domestic and non domestic customers. Please refer to the Tariff Schedules here ​

For domestic customers there is a set of charges for customers who receive a "full pressure" water supply and, in order to provide support for poorer families, a separate set of charges, which are at a reduced level, for customers who receive a "semi-pressure" water supply by means of a roof tank.

In addition there will be no monthly fixed charge for domestic customers.

Non domestic customers are not subject to stepped tariffs but are subject to a monthly fixed charge based on the size of the water meter.

WHAT CAN I DO IF I CONSIDER THAT THERE ARE EXCEPTIONAL CIRCUMSTANCES AT MY PREMISES SUCH THAT THE FRACTION OF WATER DISCHARGED TO SEWER, DETERMINED USING THE TABLE OVERLEAF, IS EXCESSIVE?

Where any customer considers the percentage in respect of a particular premises to be excessive the percentage may be reduced to a figure which more realistically reflects the proportion between the likely volume of sewage discharged from the premises and the quantity of water supplied.

An application form which will enable a customer to provide details of the exceptional circumstances which apply to the particular premises is available on the Council's web site or may be obtained on request to 080 131 3013, 083 7073 013 (sms only) or eServices@.durban.gov.za

WHO WILL BE CHARGED?

The volume based sewage disposal charge is payable when a premises is reasonably capable of being connected to the sewerage system, and when that premises receives a supply of water from the Council.

Properties which rely on privately owned septic tanks or conservancy tanks, or are connected to a privately owned "package treatment plant", and do not have access to a municipal sewer, will not be charged a volume based sewage disposal charge but will continue to be responsible for the operation and maintenance of their septic tank, conservancy tank or privately owned treatment plant.
