The aim of the present study is to determine the flow pattern and depository rate of contaminants in a pipe network developed at a laboratory scale, representing a three storied residential building. The water circulated through it after spiking with different physicochemical and microbial contaminants. The flow and depository pattern of parameters such as turbidity, dissolved organic carbon and microbial contaminants were analysed in running as well as in standstill condition. The observations were made for 24 hours. The turbidity reduced drastically from 130 NTU to 3 NTU in running condition and 130 NTU to 1 NTU in standstill condition. The Dissolved Organic Carbon decreases from 100 mg/L to 88 mg/L and 100 mg/L to 86 mg/L under running condition and standstill condition, respectively. The MPN test revealed steady increase in the microbial content during initial period and then increased drastically.
