1 EXPERIENCES IN PROMOTING SUSTAINED IMPETUS FOR WATER & SANITATION PRESENTED BY ENG MALAQUEN MILGO - CEOATHI WATER SERVICES BOARD
2 VISIONA future with reliable, affordable, and safe water and sewerage services that exceed our customers’ expectationsMISSIONTo improve the quality of life of our community by ensuring access to safe water and sewerage services.
3 IntroductionAWSB was formed in March 2003 as a result of Water Act 2002;Mandate: broadly responsible for developing infrastructure and provision of Water supply and sewerage services;Coverage: Nairobi City, Thika East , Thika West, Ruiru, Gatanga, Kiambu East, Gatundu, Limuru, Lari and Kikuyu Districts;Area of coverage is about 4,000Km2 with a population of 5million people.Source: Water Service Boards Areas of jurisdiction, Ministry of Water and Irrigation
4 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 The yield from this source was 5,000m3/day.Ruiru (photo) is the second water source developed during 1936 to Ruiru dam completed in The yield is 22,000m3/day.
5 Developed Water Sources for Nairobi City Third is Sasumua dam located up stream of the Chania river was completed in 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.(schematic diagram on source next slide)

8 Development objectives of WaSSIP II Rehabilitating selected existing water production, transmission, storage and distribution facilities and waste water collection, treatment and disposal facilitiesConstruction of new water treatment works in identified townsExpanding piped water supply services to underserved areas and through expansion of primary and secondary distribution systemsRefining and strengthening the institutional structure, emphasizing on increasing accountability and transparency of the institutional, governance and management framework
9 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;

12 SITUATION ANALYSISCurrently, 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% deficitIt is estimated that current service levels for Nairobi City stand at 76 l/c/d (Source: Draft Working Paper No 1 of February 2011, Agis BCEOM/MIPP)
13 Current Status on Sewerage The sewerage infrastructure in Nairobi only covers 25% of the area and serves about 40% of the population.Currently, there are 178,099 connections to the existing sewerage network.
14 Completed worksRehabilitation of Sasumua dam spillway and embankment to restore the dam’s storage capacity from 5 million m3 to 16 million m3.Rehabilitation of 23kms of water network within the city of Nairobi and two booster stations aimed at reducing ufw by 35% by December 2011Drilled and equipped 45 boreholes in the Nairobi City in low income and high density areas producing 20,00 m3 per day.
15 Construction of 40 elevated tanks of various capacities with a total storage capacity of 1,500 m3. Constructed 4 new water treatment plants to produce 23,000 m3 per day.Constructed 2 new water treatment plants in Komothai, and Bathi to produce 9,000 m3 per day.
16 On-going worksConstructing a new raw water intake works and 2 treatment plants to produce 13,000 m3 per day in Ruiru, and 4,000 m3 in Juja.Supply of 340Km water pipes and assorted fittings, 10Km sewers, manhole rings and fittings. WSPs implemented the works under the KKV programme
17 Rehablitation works for the main Ngethu to Gigiri Rehablitation works for the main Ngethu to Gigiri. The scope of works includes construction of 17Km transmission main from Kwamaiko to Gigiri reservoir and rehabilitation of Ngethu-Gigiri pipelineConstruction of 20 water kiosks, 20 ablution blocks, drilling and equipping 6 boreholes, 6 elevated steel tanks capacity 48m3 each, and connection of existing facilities to the water and sewer network is ongoing. The works are under the project construction of Independent Water Supply Points and Sanitation Blocks in informal settlements

24 ChallengesCurrently we still have high ufw standing globally at 36% with some schemes having ufw as high as 85% - IthangaHuge capital investment requirementsOur WSPs are still on a tariff which is not able to meet operational expenses with very high utility power billsImplementation of the new constitution which raises issues about status of Boards and ability to borrow.
25 Way forwardAWSB 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)The Board has developed a shopping basket of Kshs 40 billion and is keen to continue implementing targeted projects within its mandate
