ABSTRACT

Once design, construction, and development are completed, well maintenance has to begin, based on a preconceived maintenance plan regularly modified to fit the field conditions. In monitoring and recovery well planning, the direct preventive maintenance costs, rehabilitation costs, and new construction are at first glance relatively more similar in cost. Direct, immediate costs tend to exclude some real operational expenses and also the implications of future problems temporarily avoided. Routine well maintenance has a short engineering history; but where systematic maintenance inspection, monitoring, and treatment have been employed, they have visibly reduced clogging and other impacts on well performance, piping, and filtration and treatment equipment. Maintenance monitoring is the process of performing systematic monitoring to permit early detection of deterioration that may affect the well's hydraulic performance and water quality. Once maintenance or diagnostic testing has indicated that a deteriorating condition is likely to cause a problem, or has established a suitable maintenance interval, some action needs to be taken.
