In anaerobic lagoons, the bacterial activity reduces solids but often results in the production of odourous gases which makes a lagoon unsuitable except in isolated areas . Anaerobic 1 lagoons liquefy and break down manure solids, but not all wastes are totally degraded. The unprocessed solids settle at the bottom of the lagoon and accumulate as sludge. A lagoon has low initial cost and is easy to operate. Further labour can be saved by using irrigation to dispose of liquids . Long storage times permit pumping flexibility while bacteria break down 17 solids, which results in a high degree of stabilization,. | Western Australian Broiler Growers Association Poultry Farmers Association of Western Australia Environmental Code of Practice for Poultry Farms in Western Australia Western Australian Local Government Association Shire of Gingin Shire of Serpentine Jarrahdale Department of Agriculture Department of Environment Department of Health Department for Planning and Infrastructure ENVIRONMENTAL CODE OF PRACTICE FOR POULTRY FARMS IN WESTERN AUSTRALIA Environmental Code of Practice for Poultry Farms in Western Australia May 2004 Prepared by Western Australian Broilers Growers Association Poultry Farmers Association of Western Australia Department of Environment Department of Agriculture Department of Health Department for Planning and Infrastructure Western Australian Local Government Association Shire of Gingin Shire of Serpentine Jarrahdale
