Inquiry

In lieu of potable domestic water, we are planning to tap into a municipal "industrial water" line for landscape irrigation use and retention pond supplement. The municipal water system originates from the Tennessee River, and is piped to the treatment plant. Most of the water is treated and distributed as potable water but a portion is released without treatment as "industrial water" for use in cooling systems and irrigation. Would this municipally supplied industrial water source meet the credit requirements for WE 1.2 for no potable water use in irrigation?\n\nIf this source is considered potable water - not meeting the credit intent - would using captured rainwater from an on-site retention pond meet the credit requirements (WE1.1 or 1.2) if, on occasion, water from the industrial water line was added to keep the pond full?
