* [http://aplv.org/technical_resources Air in Pipes], by Gilles Corcos (available in English and Spanish). This manual is intended as a complement to handbooks on the construction of rural gravity-flow water systems. It focuses on the problems and opportunities associated with the almost inevitable presence of air in the main pipeline from the spring to the distribution tank. The manual contains new material that the author has gathered in both the field and in the laboratory and which fits into a relatively simple theoretical framework.
