FAQs about WEc1 :

Can non-potable well water that is used for irrigation contribute to potable water reduction?

Can surface water, such as water from an irrigation ditch or a local creek, be used as nonpotable water?

Do interior planters count in the calculation?

We are using non-potable water for irrigation. For drought conditions, can we hook up to a potable water source for backup and still earn this credit?

NC-2009 WEc1:Water Efficient Landscaping

Irrigation efficiency of manual irrigation

The project we are working on has very small green area and the investor is not planing to install irrigation system, but will have the vegetation manually irrigated with potable water and through hose and valves. Has anyone had the same experience? What irrigation efficiency coefficient have you used for the calculations? Thanks in advance!

You will have a hard time getting any points here. First you will need to meet the minimum of 5% garden space and planters based on building site area. Than you will need to reduced your water consumption in total and/or potable water. I'm not sure about the efficiency of the hose. Hopefully some other user can share what they have been using.
