水系统的可行性是一个备受关注的问题。联邦生存法的支持者认为，这是一个阻止新小型系统扩散并巩固许多现有系统的机会。这一论点的优点在于，如果系统总数大幅减少，首要机构的工作量将减少。如果不可行部分被定义为不符合SDWA，则会导致故障的系统将被消除。 在一段时间内，水系统的数量将大大减少。

The viability of water systems is an issue that is receiving a great deal of attention. Proponents of a federal viability law see this as an opportunity to stop the proliferation of new small systems and to consolidate many of the existing ones. The argument has merit in that if the total number of systems is dramatically reduced, the workload of primacy agencies will be reduced. If non-viable is defined in part as not being in compliance with the SDWA, the systems that cause trouble will be eliminated. Over a period of time, the number of water systems would be greatly reduced.
