Consequently, in October of 2007 the county government went into the gravel business for itself. Now the Public Works Bureau contracts firms to handle the dredging, but the Bureau of Civil Affairs collects the gravel, which it then sells. This new revenue stream for the county is expected to bring in NT $ 330 million this year.
於是縣政府自 2007 年 10 月也開始辦理砂石公共造產，改由工務局編列預算發包疏浚後，再由民政局將疏浚所得的砂石賣出，為縣庫多得一筆價金收入，估計今年可收入 3 億 3,000 萬元。
