Improvements include more efficient and reliable well pumps and motors, wider user of corrosion-resistant materials, especially plastics, and pump discharge pipe systems with improved connections for installation and removal. Assessment for preventive maintenance or rehabilitative planning depends on useful analytical tools . Well and pump performance analysis has been well supported and demonstrated for years. However, there is much education yet to do. Water supplier management teams still typically do not have sufficient objective information and quantitative evaluation techniques to make optimal decisions on well supply preservation and improvement options.
More effective guidance is needed.
