Effective filtration is essential if the clogging of irrigation nozzles is to be prevented. The irrigation filter required depends on the quality of the water, the water flow and also the type of irrigation system. Filters for drip irrigation systems need to be finer than irrigation filters used with field sprinklers.
Screen filters are the lowest cost irrigation filter available, disc filters are more expensive but have a greater capacity before they require cleaning – important for non-mains water supplies.
Sand filters are designed for use with dirty water sources such as rivers or lakes. Access Irrigation can provide advice on the setup of sand filters or sand filter arrays.
