Central African Republic - Project for Drinking Water Supply and Sanitation in three Divisional Headquarters and Surrounding Rural Areas

Table 2.2 
Project Alternatives Considered and Rejected, and Reasons for Rejection 
Alternative Option 
Brief Description 
Reasons for Rejection 
DWS
In Berberati, use of combined 
resources: ground and surface. 
In Bouar, harnessing additional 
surface water to meet the needs of 
the population. 
In Bossangoa, harnessing 
additional surface water to meet 
the needs of the population. 
Rehabilitation of the Nawouya spring 
and Samari boreholes, equipping the 
Ndao boreholes and pumping water 
from River Batouri to Berberati. 
In Bouar, rehabilitation and extension of 
the existing water treatment plant. 
Rehabilitation of existing boreholes and 
increasing production through pumping 
from River Ouham 
Requires the building of a lifting threshold and a new 
pumping and treatment station which are expensive in 
terms of investment and operation. 
Requires the implementation of more works and comes 
with other expenses relating to surface water treatment. 
More rehabilitation works and higher running costs. 
Sewage disposal 
The option for sewage disposal 
was to construct a collective 
system 
Building a traditional collective network 
(sewerage network) 
Expensive both in terms of investment and operation 
and is not suitable in a context of relatively low 
drinking water consumption. 
Solid waste disposal 
For the treatment of solid waste in 
each town, it was decided that an 
incinerator or a compost will be 
developed in each town 
Incineration involves the destruction of 
waste by heat. Composting is the 
biological decomposition of organic 
waste 
Incineration has a limited recovery rate, causes 
atmospheric pollution and produces a large number of 
solid residues which must be disposed of in a landfill. 
Composting treats only organic wastes and requires 
sorting at production.
