The water and sewerage company's designated area of supply is within Githunguri District and lower parts of Lari district and its environs. The area covered is approximately 247km2

with a total population of 200,009 people.

The mandate and objectives of GIWASCO are enshrined in the memorandum and articles of association. The principal objective of the company is to carry out the business of water and sewerage services provision within the area under its jurisdiction as provided for in the SPA withAWSB.

1.5 Existing Water Supply Situation

1.5.1 Limuru Water and Sewerage Company Limited (LIWASCO) As earlier mentioned, there are three (3 No.) existing main water supply schemes within the jurisdiction area of LIW ASCO namely:

• Limuru Water Supply Scheme which is supplied by boreholes with an approximate combined production of 3,000 m3 /day

• Bathi Water Supply Scheme which is supplied by water from Bathi Dam with an average production of 1,150 m3/day. The dam has a safe yield capacity of20,000 m3/day. The scheme has a full conventional treatment plant.

• Thigio Rural Scheme with an average production of 600 m3 /day

LIWASCO currently operates 17 boreholes with a present production of approximately 3,000 m3/day. Water from the boreholes is treated by disinfection using chlorine. Most of the boreholes pump to storage tanks and thereafter the supply water gravitates from the tanks to their respective supply areas, while some boreholes pump directly to the distribution. The Bathi River Water Scheme serves a total area of 197 km2

The distribution system is generally in good condition with exception of a few areas whose network is old and requires replacement. There are 4,683 registered connections, out of which 2,543 are active according to the WSP records. The consumers comprise a mix of domestic, commercial, institutions and a few industries. The majority of the consumers are domestic. The consumers categorised per supply area are summarised in the table below.

Time-Based

The distribution network in the three schemes is in fair condition with NR W estimated to be 34% in Limuru, 27% in Bathi Rural and 33% in Thigio Rural Schemes. There is need for expanding the network to adequately serve the underserved and unserved areas. The high NRW occurs due to mal-function of the consumer meters as well as physical losses due to pipelines in poor conditions in some schemes. LIWASCO's service area is developing at a relatively high rate with new areas having been allocated for development; other areas have already started development. The distribution system covers only part of the area of supply and comprises ofuPVC & HDPE pipes diameter ranging in size from Y2 inch (DN 15) to 6 inch (DN 150). Due to the insufficient coverage of the main distribution lines of 1 inch (DN 25) to ~ inch HDPE/uPVC pipes are used as distribution mains which connect several consumers. There are a number of community water projects (CWPs) under the WSP service areas, some of which the WSP has already taken over for operation. The Company has taken over 4 No. community water projects-CWPs; namely: Tigoni, Ndiuni, Kiawaroga and Thigio. In addition, LIW ASCO has constructed chambers to protect springs - namely Kijabe Springs where nearly 200 m31day is abstracted and treated at composite treatment units (CFUs) to serve consumers in Kijabe area. The Company has also signed a third party Service Provision Agreement (SPA) with Bibirioni and Kamirithu Community Water Projects.

1.5.2 Githunguri Water and Sewerage Company Limited GIWASCO

The main sources of water within GIWASCO's service area are boreholes and river intakes. There are 13 boreholes and 4 river intakes, while some areas are also supplied from the Sasumua and Ng'ethu bulk water supply under NCWSC. The current yield of the boreholes ranges between 5 m3/h to 16 m3/h with a present production of nearly 1,550 m3/day. The boreholes are low yielding and incur high electricity costs due to pumping. The total production from the water sources is estimated to be 2,550 m3/day based on the 2013/14 records.

The schemes are either supplied from boreholes or river sources. The borehole supply schemes include Githunguri, Gathaithi, Giatheko, Thoita, Kiratina, Mihuko, Waingere and Kiaria (1); whilst the river supply schemes include Komothai, Matimbei and Kagaa. There are also 4 offtakes which are currently inactive. These offtakes include: Kiaria (2), Gathanje, Gathigu and Kiambururu.

GIW ASCO currently operates 11 independent water supply schemes and 13 offtakes supplied from the NCWSC bulk supply from either Sasumua or Ngethu transmission mains. For the borehole schemes, no treatment is done for the water. Apart from Komothai water supply, the WSP supplies raw water to the residents. Most ofthe boreholes pump water to storage tanks where water gravitates from there to the consumers; however some boreholes pump water

directly to the distribution. The distribution system is generally in good condition with the exception of some areas whose network is old and the pipelines require replacement. There are 6,107 registered connections, out of which 3,012 are active as at March 2014.

There is an ongoing water rationing program due to inadequate water supply. Additional water sources are required to meet the increasing water demand and consequently increase access to water by extending the distribution system unserved and underserved areas. The average Non Revenue Water (NRW) is 47% over the year 2013/2014. The high NRW occurs due to under-registering of the consumer meters as well as physical losses due to pipelines in poor conditions in some schemes. A WSB is currently undertaking the rehabilitation and expansion of the existing Komothai water supply scheme. A number of water source development projects including the construction of the Matimbei and Mukuyu II small dams projects which is expected to abstract 2,000 m3/day and 4,000 m3/day respectively from the sources.

1.6 Location of the project

1.6.1 Limuru The project area is Tigoni Location of Limuru Constituency. It covers Ithanji, Red Hill and Parts of Mabrouke sub locations.

The project is located about 5km East ofLimuru town along Limuru-Banana road. The source of water is Tigoni Dam which is at an altitude of about 2000 meters above sea level. The project covers an area of about 7.0km2

• The project has all weather roads.

1.6.2 Githunguri The project area is in Nyanduma and kamburu wards in Lari sub-county and Komothai ward in Githunguri sub-County. The source of water is the Komothai water supply project.

1.7 Proposed Project Scope

1.7.1 Limuru The scope of the Project include construction of 1,000m3/d treatment plant using water from the Tigoni Dam. After treatment, the water will be pumped to the proposed elevated tank from where it will gravitate to the residents.

1.7.2 Githunguri The scope of the project includes laying of 100kms of water distribution network in the areas ofNyanduma, Komothai and Kamburu.

1.8 Current Sector Responsibilities

1.8.1 Athi Water Services Board (A WSB)

For many years, the institutional arrangements in the water sector in Kenya were unable to deliver and maintain basic water supply and sewerage infrastructure to the growing population. Following the publication of the National Water Policy in 1999, major reforms of the sector were initiated with the revision of the Water Act in 2002. The revised Kenya Water

Act officially became operational on 18th March 2003, providing a new legal and institutional framework for the management and development of Kenya's water resources as well as for the provision of water and wastewater services. The new Act defines clear roles for the different actors involved in the decentralized institutional framework that separates policy formulation from regulation and services provision.

The 2002 Water Act originally proposed the formation of seven regional Water Services Boards, but this was increased to eight Boards with the formation of the Tanathi Water Service Board (TAWSB) in 2008.

Under the Water'Act 2002, the Water Service Boards are licensed by the Water Services Regulatory Board, (WASREB) and are the asset holders of the water and sanitation infrastructure facilities within their areas of jurisdiction. The Boards were given the legal responsibility for the provision of water and sewerage services and are responsible for the planning and development of the water supply and sewerage services within their area. They were mandated to contract out delivery services to Water ~Service Providers (WSBs) to operate and maintain the infrastructure facilities. This situation has changed following the operationalization of the Constitution of Kenya 2010 in that water and sewerage services are the mandate of the County Governments. The WSPs therefore are now entities under the County Government. The asset holder of the water and sewerage infrastructure in the city of Nairobi is the Athi Water Services Board (A WSB). The Athi Water Services Board (A WSB) became operational in 2004 and has made great strides in improving water and sanitation services in its area of jurisdiction, which includes Nairobi County and the surrounding districts ofThika, Gatundu, Kiambu East and Kiambu West all in Kiambu County
