Solids and Trash
===Solids and Trash===
Excessive solids in wastewater are caused by trash entering the sewer system or generated by processes at the facility. It enters the wastewater stream and then has to be removed at the treatment process. Converting open sewer channels to piped sewers can dramatically reduce trash entering the wastewater stream. Trash traps at public markets for fish, meat and vegetable stalls is required.

Trash traps are simple devices that prevent solid waste from flowing down the drains and causing drainage problems. Traps are often located at strategic locations on the wastewater collection system. Remember that trash traps must be cleaned frequently, and the screenings should be placed in covered receptacles and disposed of as solid waste.
