Chang Shih-chiao points out that if an 18-hole golf course was given over to forest, it could hold l.5 million cubic meters of water; whereas a golf course lawn consumes about 1500 tons of water a day, about the same as 4500 residents of Taipei. Director Fan Yang-lou says the Laoyeh Course, which is only half covered by lawn, consumes only a little less than 100 tons a day.
張石角指出，一個十八洞球場，若為森林，可涵養一百五十萬立方公尺的水；球場草皮保養，一天則要用掉約一千五百噸左右，相當於台北市四千五百人每日的用水量，草皮才鋪一半的老爺球場主任范陽樓也說現在一天要用近百噸的水。
