The Role Of Gis In Distributed,decentralized Wastewater Management

摘要

In the 1997 Response to Congress on Use of Decentralized Wastewater Treatment Systems,the U.S.Environmental Protection Agency determined that "with the technology now available,adequately managed decentralized systems can protect public health and the environment as well as provide long-term solutions for the nation's wastewater needs." The key words in this statement are "adequately managed." The charge to meet this need often falls to local jurisdictions,typically county health or planning departments,to ensure that the decentralized infrastructure (gen-rnerally onsite or small cluster systems) is managed both administratively by the jurisdiction and operationally by a private operator or service district.
