Buried Pipelines for Surface Irrigation

This book is a comprehensive guide to the use of low-pressure pipelines instead of canal distribution systems for surface irrigation. Buried pipeline systems offer improvements over canals, without the sophistication and high cost of pressurized sprinkler and trickle irrigation. It is, therefore, an intermediate irrigation technology, which may be more appropriate on many irrigation schemes in low- and middleincome countries. It will normally be more efficient and more convenient in operation than conventional canal systems, with fewer environmental problems. The costs are considerably lower than for sprinkler or trickle systems, and comparable to those of lined canals. The book identifies circumstances where buried pipe systems will be most appropriate, identifies the different types of system, and presents recommendations on selection, design, construction, operation and maintenance of buried pipeline systems.
