The greater the population there is in a locality, the greater the need there is for water, transportation,and disposal of refuse.
——这是个错句，多写了两个 the（红色的多余，必须删去）。改为：
The greater population there is in a locality, the greater need there is for water, transportation,and disposal of refuse.
显而易见的是：两个 greater 都是作定语，不是表语。冠词 the 是分别限定后面名词population 和 need 的。
如果让 greater 作表语，那么这种表达，正确的形式才是：
The greater the population is in a locality, the greater the need is for water, transportation,and disposal of refuse.
