WE Credit 2: Innovative Wastewater Technologies
2 Points

Intent
To reduce wastewater generation and potable water demand while increasing the local aquifer recharge.

Requirements
OPTION 1
Reduce potable water use for building sewage conveyance by 50% through the use of water-conserving fixtures (e.g., water closets, urinals) or nonpotable water (e.g., captured rainwater, recycled graywater, on-site or municipally treated wastewater).
OR
OPTION 2
Treat 50% of wastewater on-site to tertiary standards. Treated water must be infiltrated or used on-site.

Potential Technologies & Strategies
Specify high-efficiency fixtures and dry fixtures (e.g., composting toilet systems, nonwater-using urinals) to reduce wastewater volumes. Consider reusing stormwater or graywater for sewage conveyance or on-site mechanical and/or natural wastewater treatment systems. Options for on-site wastewater treatment include packaged biological nutrient removal systems, constructed wetlands and high-efficiency filtration systems.

WEC2: 创新废水技术
2分

目的
减少废水产生、减少自来水使用量，补充地表涵养。

要求
选项1
通过使用节水器具，或非自来水，减少自来水一次性转化为排放废水50%。
或者
选项2
现场处理50%的废水，使其达到三级深度处理标准，处理的废水必须在本地渗透或使用。

技术措施和策略
恰当使用经认证的用水器具和配件，采用高节水器具（如节水便器和小便器）、或干式便器，
如便器与生化制费系统关联。减少废水排放，考虑采用回收雨水、中水冲厕，及机械和现场自
然废水处理装置。现场废水处理措施可包括：取出废水中生物营养物的水处理系统、人工湿地
和高效过滤系统。
