Sewage disposal

Description:

University of Phayao undertook a contract to repair and improve the wastewater treatment system and it also provided the maintenance services for the wastewater treatment system in the building every month. The Environmental Section, Division of Building and Facilities, is responsible for this project. They have a duty to cleanse and maintain those sewers (and any lateral drain) to ensure that the area that they serve is effectively drained. There is also a duty to make provision for the emptying of those sewers, normally through sewage treatment works, or where appropriate, through discharges direct to watercourses.
