GENERAL
2 Credit Points: Demonstrate that the water make-up requirements for all exterior
water features can be served using the Exterior Water Allowance (as outlined in the
calculations and methodology section); and
Where recycled water is not immediately available, demonstrate that a recycled water
mainline loop has been installed which allows for the future switch from potable to
recycled water for exterior water feature demands when it becomes available. All pipes
