Water Act Article 22
If the authority-in-charge determines that scientific and technological advances have made water conservation possible under its jurisdiction, it may order water right holders to improve their water conveying or usage technology or facilities. The water so saved may be redistributed for use, provided that those who acquire the right to use the surplus water shall bear the costs and expenses of such improvement.
中文原文 水利法第22條
主管機關根據科學技術，認為該管區域內某水源之水量可以節約使用，得令已取得水權之原水權人，改善其取水、用水方法或設備，因此所有剩餘之水量，並得另行分配使用，但取得剩餘水量之水權人，應負擔原水權人改善之費用。
