Domestic users are by far the biggest generators of wastewater due to the wide variety of uses of water in the home. The kitchen, bathroom, and toilet are the heaviest users of water, with toilet flushing consuming the most water.

Check your downpipes

Householders can help ensure the wastewater system runs efficiently by checking that house roof downpipes are not being fed into gully traps but into a stormwater drain. Proper installation will ensure that your stormwater will not get into the sewer to cause overflows during times of heavy rain. This will avoid raw sewage waste seeping into rivers and spilling onto streets and private property.

Reporting any overflows seen also helps make service delivery more efficient.


Avoid waste disposal units

Another way you can help the system work more effectively is avoiding installing waste disposal units or waste grinders where possible, as these put an extra load on the sewerage system with the volume of matter requiring decomposition. It is better to compost kitchen wastes. Make sure you don't let excess fats go down the drain, as these are a common cause of blockages.


Industrial responsibility

Industry can also assist by adopting cleaner production methods of waste minimisation as well as onsite treatment of by-products where warranted. These measures can have a significant environmental benefit as many firms use large amounts of chemicals in their manufacturing process and the resulting by-products are then introduced into the sewer system.
