6.4.1 Water reuse policy
In 2025, Srinakharinwirot University (SWU) had a policy in place to maximise water reuse across the university. The Water Reuse Policy was officially announced on 13 December 2024 (BE 2567) and sets out how wastewater from university buildings is treated, checked and reused on campus.
Water Reuse Policy
The policy follows the National Environmental Quality Promotion Act and the Ministry of Natural Resources and Environment standards on effluent discharge from buildings. Its main measures are as follows.
1) System restoration: defective or damaged on-site wastewater treatment systems in academic buildings, administrative offices and staff residences must be repaired so that they work at full capacity.
2) New and renovated buildings: any new construction or major renovation that needs budget must include a preliminary wastewater treatment system before discharging into the university’s central drainage, and the discharged water must meet the required standards.
3) Quality monitoring: the quality of wastewater from every unit and of the final treated effluent is monitored and controlled continuously.
4) Reuse of treated water: the university supports reusing treated wastewater for beneficial purposes on campus, such as landscape irrigation.
5) Research and innovation: the university supports research, development and new techniques in wastewater management.
These measures come from the university’s Announcement on the Policy on Wastewater Management Operations, issued under Sections 34 and 37 of the Srinakharinwirot University Act, which also supports the reuse of treated wastewater within the university premises (Figure 2).
Announcement date
The Water Reuse Policy was officially announced on 13 December 2024 (BE 2567), as stated at the end of the document. This date falls within the 2022–2026 period, and the policy remained in effect throughout 2025.
