The Rain Bird horizontal action impact-drive sprinkler head was recognized as a historic landmark of agricultural engineering in 1990 by the American Society of Agricultural and Biological Engineers. [3] This invention led to sprinkler irrigation development that currently exceeds 50,000,000 acres (78,000 sq mi; 200,000 km 2) worldwide.
An impact sprinkler (sometimes called an impulse sprinkler) is a type of irrigation sprinkler in which the sprinkler head, driven in a circular motion by the force of the outgoing water, pivots on a bearing on top of its threaded attachment nut. Invented in 1933 by Orton Englehart, it quickly found widespread use.
Water tariff for irrigation fluctuates between the US$40 ha/year for irrigation systems supplied by surface water and 150-200 US$ ha/year for irrigation systems supplied by groundwater. Water tariffs had to cover both the cost of operation, administration and maintenance at the module level and the module's share of costs at the main canal and ...
The water management signified a large subsidy on irrigation schemes. From 1980 the operation and maintenance of many irrigation projects was gradually handed over to water user organizations (WUA's) who were to assume these tasks and a large part of the costs, whereby the water rights of the members had to be respected.

The manual consists of performance indicators (PI) of water supply management along with indicators for human resources, infrastructure, operations, quality of service and economics. The manual is targeted on entities such as utilities, regulatory authorities, public administration and consumers. PIs are considered as tools that help an entity ...
