The costs for these systems are considered reasonable in contrast with conventional systems costs. They can work automatically, as the human intervention is required only when it comes about supervision.© Andy LoghinThank you!Vă mulțumesc !Răzvan  G.VOICU, dr.eng.environmentrzvnvoicu@yahoo.comgetiiliberi@gmail.comNational Institute of Hydrology and Water Management Laboratory of Eco-Hydrology, RomâniaEric L.KAY, Senior project managererickay@kayassociates.comKAY ASSOCIATES, Comox, BC.
