Abstract
A solids collector for collecting solids in waste water that are heavier than water includes a roto-molded plastic container having a cylindrical sidewall and a downwardly sloping bottom. An inlet and outlet are connected to the sidewall substantially above the sloping bottom so that solids that are heavier than water in the waste water coming into the container through the inlet have residence time in the container long enough to gravitationally separate towards the bottom. Waste water depleted of solids that are heavier than water discharge from the container through the outlet.
