Consumption Pattern Analysis of Water Consumption For Commercial Connections in Davao City

This study applied the fundamental time series analysis to evaluate the distribution, trend, and later forecast of water consumption for commercial connections by classification of Davao City Water District (DCWD). As such, this study examined the relationship between time and the water consumption of Davao City’s commercial connections over time. The monthly water consumption of commercial connections, categorized by classification per water source systems, was the data source for this study, which ran from January 2015 to December 2019. The four categories of commercial connections’ time series statistics suggested that, from 24 million cubic meters in 2018, commercial consumption dropped to 20 million cubic meters in 2019. This decline is explained by a decrease in consumption of commercials 2.0 and 1.25 classification. The data showed that during the first quarter of the year, increases were observed within five years (short-term). For commercial type 2.0, in 2022, forecasted water consumption would reach 14 million cubic meters in some improved areas of operations. Hence, specific forecasting by type of connection requires in-depth analysis. Thus, further study is required for long-term forecasting.
