Abstract

See full text

This application discloses an advanced design method for customized RCP, (cRCP), with one or more made-to-order reinforcement cages supporting one or more wall-encapsulated heat-exchange channels, cast with special-batch (SB) concrete having additions of fine-disperse CaCO3 and particular polymer fibers; the resulting Single- and DoubleEPipe sections especially adapted for heat exchange with pipe-internal wastestreams and/or groundwater and including provisions for an optional graywater accumulator for efficient recapture of both water and energy.
