The application of IWRM principles in Kerarapon water project, Ngong, Kajiado district.
Abstract
Kajiado District about 25km from Nairobi City. The water scheme covers an area of 3.7 km² and
supplies water to the area’s residents for domestic and livestock use. A central challenge facing
the area has been the availability of water, which is supplied to the residents twice a week.
Water demand for an urbanizing population increases the stress on the limited water resources,
and exacerbates competition between the sectoral users of Kibiko, Veterinary Farm and
Kerarapon residents. Similarly, the competing demands from the water scheme have resulted in
conflicts between the KWP management, and the Olopolos and Maasai pastoral communities
who rely on the same water source for their livelihoods. The water is not treated and is taken
directly from the Gakong Springs.
This study aimed at assessing the quantity of the water, its use based on the principles of
Integrated Water Resources Management which stipulates the efficient use of water, and the
active involvement of all stakeholders in decision-making processes towards the sustenance of
water resources. Based on the concept of IWRM, it was established that, at present, the water
demand at Kerarapon is greater than the water supply from the catchment area, which has been
worsened by the inefficient water uses. Moreover, there is a general lack of water management
practices which has led to increasing water losses. The catchment area should be protected from
environmental degradation such as poor land management, bad agricultural practices and advice
should be sought from relevant stakeholders. The absence of environmentally sustainable water
resources management policies such as IWRM, has contributed to the arising tensions amongst
various sectoral users.
The IWRM principle which states that ‘women play a central part in the provision, management
and safeguarding of water’ is essential in the local context of the Kerarapon Water Project,
which is hampered by a lack of capacity building, as well as the presence of women in decisionmaking.
Although there is a legitimate water users association in place, the recognition of
women in the planning, development and management of water resources is fundamental.
Addressing the present and future water related problems in KWP, calls for proper water
management. The existing inadequacy of water from the springs must be rectified by exploring
alternative options to improve the water availability.
The soil tests conducted have indicated that the existing soil type within the catchment area has
a good soil water intake. This research recommends the practicing of artificial water recharge
methods, to increase groundwater resources in the catchment area. Similarly, addressing the
water quality in the area should be strongly emphasized, in order to improve the present water
treatment processes. In addition, a concerted effort should be made by the water management
committee to familiarize itself with legal, institutional and policy documents related to the water
sector, to enable the successful implementation of the IWRM concept in KWP.
