Water Cycle Nebel & Wright 1998

Luckily, receiving waters i.e. reservoirs, lakes and rivers between source and treatment serve as a buffer, since they all have the capacity for self- purification, involving bacterial adsorption and sedimentation, predation, dilution, thermal effects, solar radiation and other factors. It’s most effective in warm temperatures and low rainfall.
