Weekly rainfall and weekly flow prediction, adapting single time series approach were conducted at kothamangalm tank system. The main events related to roof runoff are rainfall, splashing, and sometimes gutter overflow. Since rainfall events are stochastic in nature, historical data recorded by the Bureau of Meteorology are used to derive stochastic models for these stochastic processes. The rainwater tank storage is assumed to be filled by roof runoff and, if instantaneous demand cannot be met, supplemented by tap water. Two types of household demands are supplied by the rainwater tank: toilet flushing and garden/lawn irrigation .The results indicated that the raw prediction of weekly rainfall values is closer to actual weekly rainfall values that trend identified weekly predictions. The sister seasonal time series of weekly rain were more amenable for prediction than whole parent weekly time series. This single time series approach was more suited for weekly rainfall prediction. Where a tank is the sole source of supply, determining the maximum volume of water that can be collected is only the first step to determining whether the available tank capacity provides adequate security of supply. The next step is to calculate the size of the tank needed to ensure the volume of water that is collected and stored will be sufficient to meet demand throughout the year, including during the drier months or through periods of low or no rainfall.
