Introduction

Today, more than ever, energy plays a vital role in the planning and operation of any water resources development project. Providing safe, reliable ground-water supplies at the lowest possible cost requires careful design of all factors affecting the pumping and transportation of water, from its source in the aquifer to its final destination and use.

Minimizing energy consumption can result in huge operational savings over the lifetime of any water resources project. One example of energy waste is the head loss associated with the entrance of ground water into the well. Minimizing this head loss requires careful consideration of the relationships between aquifer and gravel pack materials, well screen characteristics and location, and pumping rates.

Understanding the laws and principles governing these interrelationships is the subject of extensive research conducted by Roscoe Moss Company. The need for a study of this type and magnitude has long been overdue in the ground-water profession. Too often, critical factors affecting the design and construction of water wells are being obtained from unverified general assumptions, outmoded techniques, or application of methods and values which clearly do not apply. Consequently, many wells continue to be improperly designed, with results ranging from marginal to complete well failure.

This report presents the reader with the results of this study.
