Water demand

Water demand takes into account consumer demand and non-consumer demand.
The first is the demand from the sectors that take water and absorb or transform it. It is the water used for:

  • the beverage,
  • the irrigation,
  • livestock watering,
  • construction work,

The second is the demand from sectors where the water used can still be exploited for other purposes. This is the example of the water used for:

  • the operation of turbines for the production of hydroelectricity
  • fishing / fish farming
  • tourism ….

Consumer demand.

It is the most important in the area of ​​competence of the GSA.
Without being able to estimate the quantities of each demand category, we will only cite the different categories:

Domestic demand.

urban environment with ONEA: 40 l / d / inhabitant
rural area: 20 l / d / inhabitant.

Demand for breeding: 35 l / d / unit of tropical livestock

Request for irrigation.

  • small areas: 1,500 m3 / ha / year
  • improved lowland: 5,500 m3 / ha / year
  • market gardening: 8000 m3 / ha / year.

Non-consuming demand.

  • hydroelectricity (SONABEL- Kompienga)
  • fishing / fish farming and forestry
  • environment, tourism and leisure
  • gold panning.

To conclude this point on water demands we note that in the absence of data specific to the area of ​​competence of the GSA, we remain in the national level estimates which are:

  • irrigation: 64%
  • domestic water: 21%
  • breeding: 14%

However, demands for public works and buildings, for industry and for gold panning are increasing in the area.
