Comparison of residential indoor water consumption patterns in Chiang Mai and Khon Kaen, Thailand

摘要

Investigating the microcomponents of water consumption provides information that can improve the efficacy of water supply plans and water policies. If a municipality hopes to decrease total water consumption, realistic policies can be implemented only if the microcomponent use in that specific location is known. For example, in Singapore, where water consumption for showers is high (75 Lpcd, 45% of total indoor consumption), providing financial incentives for low-flow showerheads is an effective policy. On the other hand, such a policy is useless in Hamburg, Germany, where water consumption for showers (30 Lpcd) is about one third that in Singapore.
