A convenient method for designing sewage oxidation ponds, based on pond kinetic theory, is presented. For any location in Australia, the method enables the area of the first pond in a series to be calculated simply with the aid of two charts. The first of these charts gives a climatic factor, based on temperatures, and the second gives an area factor, based on influent BOD and pond depth. Although the climatic factor chart presented is for Australia, similar charts may be prepared for any region where the required temperature data are available. An equation for designing the second and subsequent ponds in order to achieve a specified reduction in faecal bacteria concentration through a pond system is also quoted. Careful attention should be paid to the design of pond inlets in order to promote mixing of the influent with pond contents. Depth of primary ponds should be increased around the inlet, so that locally accumulating sludge does not seriously reduce water depth. /Author/
