Administratively it is divided into nine provinces with 72 districts (Government of Zambia; 2002) with a total population of 9.8 million in 2000; 11.7million in 2006. Rivers and Lakes Zambia has six main catchment areas Four major rivers Four natural lakes Extensive swamps Flood plains Shared watercourse systems e.g. ZRB Surface Water Quantity Zambia has generally sufficient surface water to meet the present and future demands. The total surface water potential is estimated to be 237 million m3/day, distributed among major rivers as shown. (JICA, 1995) However surface water is not available all over the country, especially the southern and western provinces depends largely on groundwater.

Groundwater: (Karstic carbonate & schist aquifers) 2. Surface Water (Kafue River 50Km & streams on the Plateau) What are the future water sources ? The main categories of competing users Lusaka Water & Sewerage Company Ltd (LWSC) Private residential plots, small holdings & industrial sites LUSAKA WATER AND SEWERAGE COMPANY LTD Abstracts about 50% from aquifers in Lusaka urban and adjacent areas. About 50% treated water comes from Kafue Rivers Distributes water to about 40% of Lusaka Plateau. Current abstraction is estimated to be in the range of 50.265 × 106m3 year-1 to 65.385 × 106m3 year-1, which is already well over the annual recharge of 45.44 × 106m3 year-1 at 8% of the annual rainfall. PRIVATE PLOTS, SMALL HOLDINGS & INDUSTRIAL SITES About 90% depend on groundwater (Boreholes & hand dug wells) Water is used for domestic, agriculture and industrial purposes Boreholes are constructed every year Lusaka Population 1964 - 196,000 Population 2006 - 1.5 million Population Growth: (a) After Independence – free movement (b) mostly attributed to rural-urban migration especially of the youth in search of employment and (c) an influx of retirees and retrenched workers from privatized mines and other companies. (d) 60-70% of this population settled in more than 33 high-density unplanned settlements or peri-urban areas of Lusaka. THE SPOON OF PIPED WATER does NOT extend to the Peri-Urban areas 2. CHALLENGE: Peri-Urban (PU) areas in Zambia JICA (2001:1) defines peri-urban areas as unplanned urban settlements that are disorderly developed mainly due to the rapidly increasing population. There are 372 peri-urban areas in Zambia; only 191 (51%) of these are legalized (GKW Group, 2006). In Lusaka, there are 33 of them including Chaisa, Ngombe, Kalingalinga, Mtendere and George. Others are Kanyama, Chipata, Kamanga, Kalikiliki, Misisi, Chawama, Jack Compound, Mandevu Table 3: Peri - Urban Characteristic features 1. Informal or formal settlements of unplanned origin: This unplanned nature is a hinderance to up-grading of services in the areas as it does not afford an easy layout of piped network in order to achieve desired higher levels of service (household connections) of 100% coverage. Misisi Comp Chawama Comp Table 3: Peri - Urban Characteristic features 2. High density low cost housing units: 3. Severe service deficiencies (poor infrastructure): 4. Unprotected wells, boreholes & dilapidated small piped water networks as main water sources: Most of the PU areas, particularly in Lusaka, are located in low flat areas, which are discharge areas and as such they have high water table often sitting on excellent aquifer systems. 5. Poor water quality and supply: e.g “Too Numerous to Count (TNTC) (Zulu and Nyambe, 2001). 6. Poor public health with high disease prevalence: water borne diseases such as cholera. 7. High population density and growth rate: For example Kanyama with 198,686 people has a higher population compared to Kabwe with 176,758 (CSO, 2000), a planned municipality with WSS network. In planning coverage 8. High unemployment levels: The unemployment levels are highest among the youth. Table 3: Peri - Urban Characteristic features (CNTD.) 9. Low income levels: 10. High illiteracy levels: 11. Sizeable number of skilled and talented human resource in various disciplines: Most of the retirees from formal employment find their new homes in PU areas. 12. Strong social, economic and religious activities: 13. Important market for goods and services: 14. Strong platform for political activities: 15. Poor sanitation with traditional pit latrine as the main type: 16. Haphazard solid waste and solid waste disposal: 17. High number of vulnerable groups (orphaned, elderly, physically challenged including HIV/Aids patients): Table 3: Peri - Urban Characteristic features (CNTD.) 18. High mobility level: general migration of rural population in search of employment, there is a high level of in and out migration from PU areas. 19. Lack of social structure, strong community based organizations & governing bodies: PU areas lack the social structure based upon traditional leadership and traditional institutions as well as strong community based organizations. 20. High levels of vandalism: Due to high poverty levels, there is a high level of vandalism in PU areas and some large ones in large towns, a high level of crime exists. 21. …………………………………………………………………………… 2.2 Water Supply and Sanitation Peri-Urban areas in Zambia are faced with several challenges in the provision of water and sanitation One major challenge in Lusaka is the need to meet the demand for safe and adequate potable water, as well as the need to provide access to adequate sanitation for inter- alia so as to meet Lusaka's ever rapidly increasing population. Kanyama population has grown to over 198,000 people Hydrogeology and geology map of the Lusaka area. The position of the Kanyama settlement is indicated. Modified from Nyambe and Maseka, 2000. Flow towards NW (mainly), SW and NE. Some of these are used as sites for both and solid disposal areas dump liquid waste Toilet under construction Kanyama is NOT on sewer line but it is depended on pit latrines commonly constructed to follow the hollows created by karstic solutions during the development of the Karstic dolomite (marble) aquifer. WDM ZAMBIA STUDY - RESULTS Completed Toilet Karstic feature Lack of sanitation facilities: mostly in form of Toilets with limited sewer facilities e.g. Lusaka peri-urban sitting on Karstic aquifer 4.Kanyama is depended on this Groundwater through shallow wells as there are few lines for piped-water Community involvement is Key to success Threats to Quality comes from wastewater discharges, agriculture, deforestation, industry and mining e.g GW Quality in KanyamaTownship – Shallow Wells WDM ZAMBIA STUDY - RESULTS Examples of Cost from Treating Cholera Patients – Money Spent on unbudgeted for Health Costs •Lusaka District had treated 739 Cholera cases last year 2004 •The average hospitalization length for 1 patient for rehydration and treatment was 5 days •The cost to treat one cholera patient successfully is US$450 for 5 days including staff overtime •For 739 patients X US$450 = US$332,550 Table 4: Summary of Access to Safe Water Supply in Zambia, 1990 – 2005 1990 2000 2005 Population Coverage Population Coverage Population (‘000) (%) (‘000) (%) (‘000) Coverage (%) Zambia 7,759 73 9,886 49.1 11,563,212 53 Urban 2,949 85 3,433 86.1 4,025,010 86 Rural 4,810 58 6,452 29.5 7,538,202 37 CSO, 2000.

Over the last two decades one of the biggest challenges of the municipal authorities has been to secure a safe and clean source of water for domestic consumption for the fast growing urban population. 3. Response Options Due to the poor performance of the institutions charged with the management of the water sector, Government realized the need to reform the Water Sector, which started in the 1980s. This necessitated putting in place the National Water Policy of 1994(NWP, 1994) which set the framework for the development and management of the water sector in Zambia, a strategy (MLGH, 2001) to tackle issues in the policy, specifically for peri-urban areas and guidelines most of which have a bearing on PU areas. •For example, the principal Water Act governing the management of water resources dates from 1948 and fails to address key modern day issues such as the use and protection of groundwater, shared international waters, or customary law. The main issues were: • Lack of a comprehensive sector policy or strategy to guide sector organisations in the performance of their tasks; • Unclear roles and responsibilities for the water sector leading either to duplication of efforts or gaps in some areas; • Deteriorating infrastructure as a result of poor maintenance and lack of new investments, with most of the investment being provided by external Support Agencies; • Erratic and insufficient funding through Government with little impact of government institutions on the ground; • Increasing pollution of water resources among other environmental problems, particularly in the mining areas; • Non-existence of comprehensive legislative framework for managing water (No sector policy on Water Resources Management (WRM) and Water Supply and Sanitation (WSS); the Water Act from 1948 was outdated and did not cover WSS); and • Lack of stakeholder involvement and ownership by consumers and users. The reforms have and are being strategically implemented into two: Reorganisation of the Water Supply and Sanitation sub-sector (WSS) from 1993 to date; and Reorganisation of Water Resources Management from 2001 to date. In 1994 National Water Policy was therefore adopted to address the issues, with emphasis on strengthening framework for Water Resources Management following an integrated water resources management approach. The objective NWP: to promote sustainable water resources development with a view to facilitating adequate, equitable and good quality water for all users at acceptable costs and ensuring security of supply under varying conditions. This objective was to be achieved through the following key policy strategies: 1. Recognising the important role of the water sector in the overall socio-economic development of the country 2. Vesting control of water resources in the country under state control. 3. Promoting water resources development through an integrated management approach. 4. Providing adequate, safe and cost effective water supply and sanitation services with due regard to environmental protection. 5. Defining clear institutional responsibilities of all stakeholders in the Water Sector for effective management and co-ordination. 6. Recognising water as an economic good Starting with WSS sub-sector, the Government enacted the WSS Act. No 28, 1997 to address the poor performance to bring about an organisational change management and produced permanent structures (Fig. 3) • that has transformed the water supply and sanitation sub-sector into institutional change management with a focus on full cost recovery, efficient delivery, transparency, and sound financial management.

This has almost been achieved (Table 6).

No. 28 of 1997 through which they can deliver the services. (ii)This option has ensured a higher degree of autonomy in operations with a promise on full cost recovery leading to a more sustainable provision of services in an efficient manner. Legalization of many peri-urban areas has facilitated planning for development processes and initiatives. Some peri-urban areas are now connected to the main water distribution net-work of commercial utilities (CU’s) and Water Trusts (Table 7).

From 1988 to 1995, the Danida-funded Community Development Programme (CDP) helped to initiate innovations in participatory planning and community contracting in selected peri-urban areas of Lusaka. (i)The DTF - a basket fund focusing on service provision to the urban poor as a response to increase coverage in peri-urban areas and thereby promoting low cost technology. (i) DTF is considered an appropriate instrument to reach the MDGs for the urban poor. By 2006, the funds had assisted in enabbling about 40,000 urban poor people to have access to safe drinking water.

Programmes from these initiatives have been incorporated into the 5th National Development Plan (5th NDP) and an IWRM /WE Implementation Plan has been developed to implement the Water and Sanitation Chapter and other water related programmes in the 5th To complement and build on the efforts to improve water management, Government in 2006 initiated the Water Sector Programme Support (WSPS) with DANIDA assistance, focusing on: 1. Rural Water Supply and Sanitation; 2. Peri-Urban and Low-Cost Housing Water Supply and Sanitation; and 3. Integrated Water Resources Management. (i) IWRM in Ministry of Energy and Water Development (MEWD), (ii) Strengthening of the water rights system administered by the Water Board (WB), (iii) Groundwater monitoring systems in pilot areas (iv) IWRM capacity built through University of Zambia (UNZA) (v) Piloting of decentralised water resources management structures and (vi) Rehabilitation and construction of small dams and weirs. With the adoption of IWRM, the water sector is now viewed in a broader context. The challenge is how to effectively coordinate and monitor policy development and implementation of the IWRM framework if the Water Sector Reforms are to succeed. To meet this challenge the Government has revised the 1994 Water Policy to include other sectors impacting on IWRM such as agriculture, hydropower, environment etc. not elaborated upon in the 1994 one. In conclusion, in Zambia, the Government has respondent to the drivers and challenges of the water resources in Zambia.
