Evaluation of water distribution systems at Igomelo irrigation
scheme was conducted to assess the performance of the scheme
after intervention of the Irrigation Management Transfer (IMT).
The scheme was divided into three blocks: head, middle and
tail end of the scheme. Three plots from each block were
selected for study, where water deliveries were monitored
throughout one irrigation season. Irrigation performance
indicators such as Dependability (PD), Equity (PE) and
Adequacy (PA) of water supply, Conveyance efficiency and
Structure Condition Index (SCI) were used to evaluate the
system. Conveyance efficiency was on average 85% for the
three sections. Dependability and equity values were 0.70,
0.62, 0.84 and 0.76, 0.90 0.96 for head, middle and tail and
sections of the scheme, respectively. The structure condition
index was on average90% for the 3 sections of the scheme.
All the above, are indicators of a system that is performing
well.
