研究表明，不同种类的草坪草以及同一种中的不同品种对水的需求存在差异，所以使用节水草坪草品种对草坪的节水具有非常重要的意义。在选育草坪草抗旱品种的时候，除了利用常规育种方法外，还可以利用生物技术，将抗旱基因导入草坪草中，得到全新抗旱品种。据估算，带有抗旱基因的转基因草坪草与普通草坪草相比，可节约一半水；如果大面积种植，可节约灌溉水20％到30％。
二、要科学合理灌溉

灌溉方式对草坪节水很重要。传统漫灌方式，灌水不均匀，浪费严重。近几年，由于水资源紧缺使节水灌溉工程得到迅速发展。目前主要的节水灌溉方式有管灌、喷灌、微灌和渗灌4种。实践证明，微灌、渗灌比较适合分行分株的农田作物，对面积大、植株多、分布均匀的草坪，这两种灌溉方式不是经济有效的。所以，城市草坪的节水灌溉主要采用喷灌的方式。

经过回收处理利用的污水叫做再生水，按工艺分初级处理水、二级处理水和三级处理水。目前草坪灌溉绝大部分直接用自来水或地下水。一方面草坪灌溉日益加剧城市供水的负担，另一方面城市的生活污水没有得到合理利用。国家环保总局公布的中国环境状况公报显示，2003 年全国废水排放总量为460亿吨，开发潜力巨大。
