Yes, Industrial wastewater treatment plants (ETP) are categorized within Production Energy Use, while Domestic wastewater treatment plants (STP) fall under Domestic Energy Use. In instances where both are combined, they should continue to be reported under Production Energy Use.
In the Higg FEM, energy use is categorized as domestic or production energy use, which is defined as follows:
- Domestic Energy Use – Energy that is consumed in non-production related areas and/or buildings such as employee washrooms, domestic-only wastewater treatment plant, or office areas separated from production, canteen and kitchen, security posts, external lighting (e.g., roadway or landscape lighting), medical center, etc.
- Production Energy Use – Energy that is directly or indirectly consumed in production-related activities or production areas such as production equipment operations, onsite energy generations for production (e.g., steam or electricity), industrial wastewater treatment plant, production area lighting, heating, ventilation, and cooling, etc.
