Condominial sewerage is the application of simplified sewerage coupled with consultations and ongoing interactions between users and agencies during planning and implementation.[1][2][3] The term is used primarily in Latin America, particularly in Brazil, and is derived from the term condominio, which means housing block.
From a pure engineering perspective there is no difference between designing a regular sewage system and a condominial one. However, bureaucratically a condominial system includes the participation of the individuals and owners who will be served and can often result in lower costs due to shorter runs of piping.[1] This is achieved by local concentration of sewage from a single "housing block". Thus a number of dwellings are grouped into a "block" known as a condominium. The condominium may share no other aspects of ownership or relation except geographic proximity. In addition, individuals and owners may share a role in the maintenance of the sewers at the block level.[3]
