This case study describes the problems that existed in a Sri Lankan
irrigation scheme prior to its rehabilitation in 1979, and the associated
irrigation management innovations introduced by the author who
was assigned to the scheme. These included providing a simplified
form of technical guidance to farmers and using organized farmer
participation in the operation and maintenance of the system through
a Water Issue Board. By gaining the confidence of the farmers and the
various line agencies working in the area, the author was able to
introduce a systematic rotational distribution of water, advance the
cultivation calendar, and increase cropping intensity.

This case study reports the author's experience with the institutional
and irrigation infrastructure of System H of the Mahaweli Multipurpose
Development Project in Sri Lanka. A coordinated approach for
achieving close cooperation between agency officials and farmers at
the field channel and distributary channel levels, combined with a
flexible delivery schedule, has resulted in an improved field water use
efficiency within the subsystem H5. An equitable allocation of water
to each field channel command area and an effective utilization of
rainfall has also been achieved.
