CLIENT BRIEF: Due to the law changes in Fiji costal developments require septic tank runoff to be further treated to control pollution of the local reefs and waterways. What we have in Fiji is unreliable, ineffecient and out dated. I want a simple functioning septic treatment system which is easily transportable, easily installed with the possibility of fabrication on the Pacific Islands. PROBLEM SOLVED: The TJ3375. 1687ltrs of septic tank oxygen diffusion, 843ltrs of clarification and venturi sludge return, plus 843ltrs of treated liquid passed through a 120 mesh/180 micron filter and onto the irrigation/evaporation field. SIMPLE, CLEAN, GREEN, ECO FRIENDLY, RECYCLABLE. PRE FABRICATED OR KITSET TO BE FABRICATED BY LOCAL LABOUR.
