Historical background – Nairobi Supply
• The initial water supply facility for
Nairobi was constructed in 1899
abstracting water from Nairobi river in
the Athi river catchment.
• Kikuyu springs were first water source
developed in 1900-1906. The yield
from this source was 5,000m3/day.
• Ruiru (photo) is the second water
source developed during 1936 to
1938. Ruiru dam completed in 1950.
The yield is 22,000m3/day.
Developed Water Sources for Nairobi City
• Third is Sasumua dam
located up stream of the
Chania river was completed
in 1956. Production is
57,000m3/day.
• Lately, Thika dam and
Ngethu t/works system were
developed from 1974 to 1994
in three phases. Total
capacity is 440,000m3/day.

Development objectives of WaSSIP II
• Rehabilitating selected existing water production,
transmission, storage and distribution facilities and waste
water collection, treatment and disposal facilities
• Construction of new water treatment works in identified
towns
• Expanding piped water supply services to underserved
areas and through expansion of primary and secondary
distribution systems
• Refining and strengthening the institutional structure,
emphasizing on increasing accountability and
transparency of the institutional, governance and
management framework
Challenges….. (some)
• Huge investment estimated at Kshs 42 Billion
required to develop infrastructure to meet
medium term (2020) water demands;
• Competing needs for scarce water resources.
Athi catchment is said to have 162m3/cap/year
against the available 650m3/cap/year Nationally.
• High unaccounted for water.
• Environmental degradation and climate change
effects;

SITUATION ANALYSIS
• Currently, the water demand stands at
672,994 m3 per day against a
production of 501,350 m3 per day –
hence a deficit of 171,644 m3/day
which is 25% deficit
• It is estimated that current service
levels for Nairobi City stand at 76 l/c/d

23
Challenges
• Currently we still have high ufw standing
globally at 36% with some schemes having
ufw as high as 85% - Ithanga
• Huge capital investment requirements
• Our WSPs are still on a tariff which is not
able to meet operational expenses with very
high utility power bills
• Implementation of the new constitution which
raises issues about status of Boards and
ability to borrow.
24
Way forward
• AWSB has negotiated funding from
various agencies to continue with the
investment momentum to the tune of
USD 160 million (IDA – 145 million and
AFD 15 million USD)
