Abstract

A system for processing sewage into vermicompost includes a holding tank for receiving and initially processing the sewage. A treatment tank, connected to the holding tank by a first pipe, is used for treating the initially processed sewage from the holding tank to ensure optimal pH, percent of solids, and electrical conductivity of the sewage. A distribution tank, connected to the treatment tank by a second pipe, is used for heating or cooling the sewage from the treatment tank as necessary. A distribution apparatus, connected to the distribution tank by a third pipe, distributes the sewage to a vermicular environment, wherein the vermicular environment contains a plurality of worms which digest the distributed treated sewage into vermicompost.
