Design of a lawn sprinkler irrigation system for Tororo golf course.

Abstract

This report addresses the challenges faced by the Tororo Golf Golf course due to the unreliable rainfall patterns that are unevenly distributed through the year affecting the normal growth of the grass on the golf course more especially on the Putting Greens since they rely on rainfall alone and this affects the consistency of the game.

Irrigation which Is the artificial application of water to plants is the best insurance against such unpredictable weather changes hence design of' a lawn sprinkler irrigation system with measures to apply correct amounts of water to the grass plant was considered and designed, climatic data; soil data, water-data and other data collected Were analysed in order to get a well representative value to use during designing work, Results were' adjusted to meet critical situations. Among the tools used during data analysis includes Microsoft EXCEL sheet, Microsoft office 2010 package and CROPWAT 8.0, CLlMW AT2.0. Irrigation software, AutoCAD 2016. and Arc Gis software and this data was presented in form of tables, graphs etc. From the determined infiltration rate of the soil i.e., 112mmm/hr; and from table 5000/5000 plus series nozzles performance from Rain bird, a rotor pop up sprinkler was selected and it was characterised with a working pressure of 35bars, a Nozzle size 3Omm, Radius of throw 1220m, flow rate of O.7 4m3/hr and a precipitation rate of 1Ommlhr for a triangular spacing based on a 62% diameter of throw. And this type of sprinkler could be employed satisfactory without any Runoff.

A rotor popup sprinkler irrigation was designed with measure to control the flow of water within the golf course, and also the fluctuating climate effect will be reduced by having water through the year. If the designed project is implemented it will adequately supply water to the greens and keep the turf healthy on the course also, it will not only eliminate wasteful over watering of the golf course but also lowering the ongoing repair and maintenance costs especially on the bare areas as a result of the lawn death within, the course Since modern irrigation practices have not been common in Uganda due to over reliance on rainfall yet not reliable any more in this century full off greenhouse effects like global warming.
