Abstract

Infrastructure/asset management is the cornerstone of water supply service delivery. Thorough knowledge of the location, features, age, capacity and risk associated with asset is required to manage the assets for sustainable service delivery. This paper presented an approach Current problem in the Bahawalpur city which is an intermediate city is that the water infrastructure is aging and is not adequate. Keeping in view the importance of infrastructure, the water supply system of Bahawalpur has been assessed and improvement interventions has also been proposed. A key component of this process is Geographical information system (GIS) based mapping and geospatial analysis of assets. High resolution Quickbird imagery is used for mapping infrastructure including pipelines. The condition assessment of each individual asset has been done in order to prioritize their replacement. Each asset is categorized in 5 classes in terms of its condition. Condition of existing assets has been done using electrical instruments like pressure gauge, power analyser, flow meter, tachometer, IR gun and visual observation. Various steps has been taken during the process including identification and development of GIS based surveyed inventory along with attributes of Water Supply assets/infrastructure.

 Results showed that 176 km of water pipes are in poor condition out of total 264 km pipelines of the city. Similarly 42 tube wells (TWs), 2 ground storage tanks (GSTs) and 6 overhead reservoirs (OHRs) are in poor condition out of total 74 TW, 18 GSTs and 12 OHRs respectively.

After the condition assessment three type of main interventions has been proposed for improvement of Bahawalpur water supply system which are; Replacement of poor water pipes, Rehabilitation of poor assets and construction of new assets.
