In Balochistan, karez (sloping tunnel) is a very old source of groundwater supply which does not use external energy. This gravity flow system has, in fact, served as a life-line for the region's domestic and irrigation water supply. With intensive installation of tubewells and power driven pumps in the open dugwells and the absence of recharging facilities, the groundwater balance has been disturbed in many parts of the province. The high cost of cleaning and deepening the karez tunnels and access wells to tap deeper aquifer poses serious maintenance constraints. As a result, the performance of the karez has been badly affected and its flow has considerably decreased and, in many cases, ceased. On an experimental basis, WAPDA rehabilitated and improved representative karezes in different areas of the province. As a result of the encouraging findings of these research studies, which enhanced the karez flows five times with a reduced maintenance cost, the Government of Balochistan requested WAPDA to prepare a comprehensive plan for rehabilitation and improvement of all karezes (about 1000) in Balochistan. To identify various problems under similar conditions, Balochistan Province was divided into three regions, namely, Quetta, Loralai and Mekran. Twenty-six sample karezes were studied in detail to form a plan for their improvement and rehabilitation. Data collection, surveys and investigations were carried out in individual karezes according to a comprehensive program prepared based on research already carried out. The data was evaluated to plan necessary improvements and rehabilitation treatments. The required improvements, in priority order, are tunnel cleaning (88%), capping of access wells(100%), tunnel lining (69%), additional branch karezes (65%), tunnel deepening (19%), storage tank lining (46%), open channel lining (35%), deep boring in karez wells (30%), low retention dams (50%), flood protection (23%) and recharge reservoirs (15%). Further evaluation indicates that the proposed improvements are economically viable. It is recommended that the proposed Karez implementations should be carried out in two phases (one short-term, one long-term) and should involve the water users in sharing the cost as far as possible.

Being an arid region, Balochistan has very little rainfall, so very little surface water is available for irrigation. The only dependable source is groundwater which is also reducing due to heavy pumpage with tubewells and dugwells and less recharging. This very precious water must be used in the most economical way. At present, farmers use the traditional method of basin flooding, losing a lot of water through evaporation and seepage. For orchard irrigation, some advanced application techniques were successfully tested. The techniques are drip (trickle), bubbler, nozzles and low head bubbler. This paper reviews these techniques. By comparing these systems with traditional flooding system, water savings of 80% by drip, 75% by bubbler and nozzles, and 60% by low head bubbler occur.
