DEVELOPMENT OF METHODOLOGY TO DETERMINE WATER CONSUMPTION PATTERN AND PER CAPITA DEMAND

Knowing the water consumption per capita per day is an important information regarding design and planning of water supply system. This paper aims to develop methodology for water consumption per capita per day and consumption pattern. The methodologies used for finding demand and pattern of water consumption are mostly based on questionnaire which having less accuracy. There was no study found that are based on real time water consumption pattern and per capita water consumption. In this study special type of device Arduino flow meter were used which were installed in the outlet of storage tank to student residence to find water consumption pattern and per capita demand. The study shows that the per capita consumption of water in a student hostel was 74.5 Liters on test day and the maximum consumption per capita was reaching to 8.2 liter on 14:00 hours having peaking factor of 2.64. The study recommend a special type device Aurdino flow meter for the measurement of real time per capita consumption and time series pattern of water consumption. The Aurdino water flow meter can provide the water consumption and pattern data with maximum procession.
