Municipal water providers spend resources on water supply projects that rely upon the same water or build parallel pipelines. All water supply projects must go through lengthy, adversarial processes to receive permits. In most drainages and even some basins, municipal, industrial, environmental and agricultural needs are met depending on which user has pre-existing rights or has the most financial and political resources. One less than optimal result is that in a drought, for example, one town may have a full water supply and a neighbouring community little or nothing.
