Waste Water Guidelines and Standards at WU

Waste Water Guidelines and Standards at WU

Walailak University has policies and guidelines on wastewater treatment from buildings and all places across the campus that are based on legally required standards and requirements to protect the ecosystems, human life, and wildlife around the campus. Besides the guidelines and policies, WU has a manual on wastewater treatment on campus.

The university has realized that the staff working on building maintenance must be supported by the university so that the staff can perform preliminary checks and tackle any problems with proper procedures. The procedures for wastewater treatment at WU prevent the wastewater from entering the ecosystems around the campus using standard measures and procedures. Regarding human life, the treatment procedures never affect the Walailak community and the local communities around the campus on odor or voice pollution. In addition, Walailak University utilizes the treated wastewater for Nile tilapia farming suggesting that the treated wastewater does not harm to living things. The following are the management measures for wastewater treatment:

The “Water Treatment System” refers to the water treatment ponds serving all buildings at Walailak University. The water treatment system includes ponds for gathering wastewater, grease traps, pump stations, aerated lagoons, and related facilities.

  1. All staff who are responsible for wastewater treatment shall perform physical wastewater treatment before release, following the standards. All buildings must be equipped with wide drainage grates for garbage and grease traps for intercepting most greases and solids before they enter a wastewater disposal system.
  2. The building staff shall record the performance of the wastewater treatment system to be consistent with the standards and ask for information on sanitation from the Division of Landscape and Building.
  3. The Division of Landscape Architecture and Environment shall be responsible for waste and hazardous waste management and wastewater treatment. The wastewater is collected from all buildings and passed through the process of aerated lagoons, ensuring that the wastewater will not enter the water systems around the campus. The division shall also be responsible for readings for PH level, dissolved oxygen (DO), total suspended solids, total dissolved solids, biochemical oxygen demand, and nitrate-nitrogen. The readings must be taken and recorded regularly.
  4. The building staff shall strictly keep improving the quality of greywater following the Notification of the National Environmental Board, No. 8, B.E. 2537 (1994), issued under the Enhancement and Conservation of National Environmental Quality Act, B.E. 2535 (1992).
  5. The wastewater treatment at all buildings must be equipped with grease traps to prevent grease from mixing with greywater, which keeps the water’s quality in the initial stage before passing to the next process. The wastewater must run through the grease traps, in which the grease and oils float at the top of the water level. All building staff must be responsible for disposing of the grease and oils monthly.
  6. The building staff of each building and all relevant organizations must strictly monitor the performance of equipment for wastewater treatment and others related to the system, including covers, wastewater pumps, aerators, sewage submersible pumps, and others. If any equipment is broken or damaged, there must be a repair as soon as possible.
