I have two sources of non-potable water in the project: gray and rainwater. These two sources, combined, are enough to supply my irrigation demand and also toilets flush for the whole year.
Question 1: given two non-potable water demands (irrigaton and toilets) is it mandatory to prioritize the distribution of water for irrigation? It sounds me I have seen this issue before but I coundt find it anywhere...
Qestion 2: to fill in the WEc2 template can I use the amount of rainwater + gray water in a single row? If no, how do I divide this amount of water from each of the sources since they all go to the same tank after beign treated?
