the sewage of the workers operate about 7, 5 m 3/ngđ. The toilet was positioned within the operator, at the same time the consciousness education of workers about personal hygiene and environmental protection; In the projects have deployed devices that use water and sanitation equipment, has septic design standards pane 3. Septic works performed simultaneously in two functions: nervous and residue decomposition.

The waste will be biodegradable, water at the same time also be cleaned part and be led through the hot aerobic biological treatment prior to self absorbent, and will periodically be worried condensate.Pros: feasible, easy to make.The downside: Rising costs to build septic collectors and processors.Efficiency: the impact will be minimized when the above measures apply.
