Dear friends,

Does 市政优质中水 in this sentence 国家体育场的雨洪利用分为雨水收集、处理、回用三个主要部分。经过收集、处理后的雨水应用于比赛场地草坪灌溉、空调水冷却、冲厕、绿化、消防等9类用途，与市政优质中水共同组成国家体育场的回用水系统。mean drinkable water of the municipal administration? (which doesn't make any sense to me)

中水回用系统 = intermediate water reuse system

优质排水 = high quality wastewater

优质排水作为中水水源，进入小区的中水处理系统处理后回用，而粪便污水和厨房废水则直接排放。盥洗废水、淋浴废水、洗衣废水等这些废水人们以前也直接用来冲洗厕所，现在作为中水水源，经处理后再回用于厕所的冲洗，人们在感官上、思想观念上都较为容易接受，对中水回用的推广有很大的益处。

市政优质中水 ~ high quality wastewater which has gone through intermediate reuse processing provided by the municipal government
