A project site is chosen in a rural area. In the charrette the project team is discussing the
option of including a packaged biological wastewater treatment system to treat 100%
wastewater on-site to tertiary standards. What statements are true about the decision to
include one of these systems?(choose 2)
A: Public infrastructure costs would be reduced
B: The recycled water could not be used for fountains in the landscape
C: Building energy costs would be decreased
D: The project may earn 3 points for this decision

参考答案: AD

本题解释:
Notes:
Reference: Water Efficiency Credit, Innovative Wastewater Technologies
The project would earn 2 points for Water Efficiency Credit, Innovative Wastewater Technologies
and 1 point under ID for treating 100% of wastewater on-site to tertiary standards.
One issue with packaged biological wastewater system to treat wastewater onsite is they have
high initial costs.
Building energy costs would increase because these types of systems require energy to run.
Public infrastructure would be reduced to the rural area because the sewage drains would not
need to be run to the site. However it is possible the city may require the sewage lines to be
installed anyway.
The water could be used in the landscape. Tertiary treatment, or advanced treatment, removes
specific residual substances, trace organic materials, nutrients, and other constituents that are
not removed by biological processes. Tertiary-treated recycled water is safe for all human contact,
except drinking.
