Combined Sewer Areas

Hi Scott, Thanks for your comment. We had a similar discussion when we were considering how to address wastewater from sinks, showers, etc. We agreed that the reduction of wastewater for those applications is credited under the water fixtures credit. Similarly, reducing a project’s runoff volume is credited under the sustainable sites stormwater design credit and would not be eligible for credit under Option 1 of the Sustainable Wastewater Management Credit. Option 1 is designed to specifically reduce wastewater volumes from toilets and urinals.
