Under the Irrigation Systems Management Research Project, the WAPDA, SCARPs Monitoring Organization has developed a computerized database covering particulars of the SCARP tubewells and their subsequent monitoring results (specific capacity) as an indicator of well performance, and water quality. In this paper, a classification of SCARPs tubewells presently in the database has been presented by schemes (Units of SCARPs), representing a commonalty in design and construction. The tubewells' performance record has been clarified by groups of wells in different SCARPs and, separately, for the originally installed and replaced tubewells. The basic objectives of the classifications were to provide an overview in respect of the dominant characteristics of the tubewells (and variations therein) in different schemes for the benefit of prospective users of the database. The classification has inter-alia helped in highlighting significant tubewell factors and to the schemes in which they were installed.

To investigate possible causes of tubewell deterioration, this study based on the available computer database of SCARP tubewells was undertaken. The average rate of decline in the specific capacity over the eight-year operation was used to characterize the performance of tubewells in different SCARPs. This was correlated with different parameters such as acceptance specific capacity, actual discharge in relation to design, development time, lithology, slot size, screen material, and saline and fresh water tubewells. The analysis concluded that some of the above mentioned parameters have a direct relation to the performance of the tubewells.
