SSc6.1 Storm Water Design

• Quality Control
• Credit Intent
• Limit disruption of natural hydrology by reducing
  the impervious cover, increasing on-site
  infiltration, and managing storm water runoff.
• Potential Technologies Strategies
• Design the project site to maintain natural storm
  water flows by promoting infiltration.
• Specify vegetated roofs, pervious paving, and
  other measures to minimize impervious surfaces.
• Reuse storm water volumes generated for
  non-potable uses such as landscape irrigation,
  toilet and urinal flushing and custodial uses.

SSc6.2 Storm Water Design

• Quantity Control
• Credit Intent
• Reduce or eliminate water pollution by reducing
  impervious cover, increasing on site
  infiltration, eliminating sources of
  contaminants, and removing pollutants from storm
  water runoff.
• Potential Technologies Strategies
• Specify vegetated roofs, pervious paving, and
  other measures to minimize impervious surfaces
  and promote infiltration, thereby reducing
  pollutant loadings.
• Use sustainable design strategies to design
  integrated natural and mechanical treatment
  systems such as constructed wetlands, vegetated
  filters, and open channels to treat storm water
  runoff.

WEc2 Innovative Wastewater Technologies

• Intent
• Reduce generation of wastewater and potable water
  demand, while increasing the local aquifer
  recharge.
• Technologies Strategies
• Specify high-efficiency fixtures and dry fixtures
  such as composting toilet systems and non-water
  utilizing urinals to reduce wastewater volumes.
• Consider reusing storm water or grey water for
  sewage conveyance or on-site wastewater treatment
  systems.

WEc3.1 3.2 Water Use Reduction

• Intent
• Maximize water efficiency within the buildings to
  reduce the burden of municipal water supply and
  wastewater systems.
• Technologies and Strategies
• Use high-efficiency fixtures, dry fixtures such
  as composting toilet systems and non water
  consuming urinals, and occupant sensors to reduce
  the potable water demand.
• Consider reuse of storm water and gray water for
  non potable applications.
