Technical aspects and cost estimating procedures of drip irrigation systems: main report
Expanded Title:Research funded by the Water Research Commission and projects completed by the Agricultural Research Council’s Institute for Agricultural Engineering on the performance of surface and sub-surface drip irrigation found that the emission uniformity as measured in the field declined over time for all dripper types. This indicates a decline in efficiency due to clogging or lack of maintenance. Correct planning, design, installation and maintenance is essential and it is recommended that regular water quality analysis be carried out to identify potential clogging problems. The results of all these research projects created useful information on costing, choice, operation and maintenance of drippers and filters. It was concluded that this knowledge must be disseminated by means of technology transfer and training sessions for designers and farmers. Through this technology exchange project, a manual for designers and a manual for farmers has been developed. It provides guidance in the selection, planning and design of drip systems for designers and it enables irrigators with drip irrigation systems to apply good management and maintenance schedules. This enables them to adhere to the objectives of the National Water Resource Strategy (2004) regarding the efficient and beneficial use of water. The purpose of the manuals is to provide a comprehensive information document for irrigation designers and farmers operating in South Africa and other SADC countries. It should be read and used in conjunction with the KBase, (a database developed as part of the WRC project by NB Systems) which contains technical information on drippers and filters, and the IRRICOST spreadsheet model, a cost estimating tool that was adapted specifically for the purposes of the WRC project by the University of the Free State. The manual covers the technical aspects and cost estimating procedures of designing surface and sub-surface drip irrigation systems. This manual includes recommendations and guidelines regarding the suitability and management of soil and water for drip irrigation, and the selection, costing, design, operation and maintenance of drip irrigation and filtration equipment. It is aimed specifically at drip irrigation in field and permanent crop applications, and does not apply to greenhouses or specialised fertigation units.
