The dynamic between public and private systems has always been interesting, especially in the case of water and wastewater systems. Public water systems are usually non-profit entities managed by local or state governments, for which rates are set by a governing board. On the other hand, private water systems can be for-profit systems managed by investors or shareholders. Though rates are monitored by a state’s public commission, private systems are not necessarily subject to this regulating board. Additionally, the difference between public and private is not always distinct, as we sometimes see in Public-Private Partnerships. In this post, we present some interesting facts and figures based on an analysis of national data on ownership of water utilities.
