Water quality
Water is an essential item for the development of life. Protecting its quality represents a major stake for public health.
It is of vital importance that you report any burst pipe you come across on the CDE water supply network to the closest branch to your residence.
Proper usage of water
Coloured water does not necessarily mean it is not fit for drinking. This colouring, in most cases, is usually due to some disruption occurring in the supply network.
- Let the water from your tap flow for one to two minutes for the colouring to disappear. If this colouring persists, do not hesitate to report same to the CDE branch in your neighbourhood. Giving this information to the operator will enable the latter to investigate why and to immediately set corrective actions in motion so as to bring the situation to normal.
- For individuals having private water storage facilities, it is imperative at least once each year to empty and clean the tanks, with inspection and maintenance of faucets and valves, rinsing of the walls and flooring, evacuation of settled matter and spraying with eau-de-javel.
Water requirements
A distinction is made between:
- The unit requirement for a specific instantaneous use as for a shower
- The global daily requirement for a user which is the sum of the unit requirements resulting from the uses made of water
- The water demand which is the quantity of water that is extracted from nature at any particular instant to cover the various requirements as a result of observed losses in production at the point of use.
Requirements for domestic uses
Excepting wastage, observed statistics within households show as follows:
- One toilet flush 10 litres
- One washstand for shaving, washing mouth and head 10 litres
- One shower 25 litres
- One bath 150 à 120 litres
- One 4 Kg machine wash 80 to 100 l/cycle
- One 5 Kg machine wash 120 to 150 l/cycle
- One dish wash (10 plates) 50 litres/cycle
The water requirements of a human being are between 15 litres/day for the small user, through an average of about 60 litres/day as observed in our secondary towns, to about 250 litres/person/day within the residences of senior executives who own grass lawns, cars and tiled floors. A human being drinks between 1 and 3 litres per day.
