Summary. From the answers to questions, 47.5 % of answerers are farmers corresponding to Lamphun Office of Labor’s data having shown that the important occupation of Lamphun province is agriculture such as rice farming and Longan gardening as a key sector of Lamphun economy. Besides this, there are laboring and household industries. As a result of analyzing data and water use, it is found that water is mostly used for consumption and agriculture. This is an indication that rural public infrastructure, particularly the project’s area, is not enough; therefore, people have to rely on water from River Ping. If flood or drought occurs, it will have an impact on people living in the area. 5. Quantitative data from other authorities to support research results. From 4.1.3 Satisfaction level towards working No.7 ‘Activities of the project include resolution of flood and drought’ is the average of 4.52 (very high) and No.13 ‘The project to develop the upper River Ping Basin corresponds to people needs truly’ on the average of 4.53.
