UD supplies insufficiently,
the demand of Qual. A (or A+B) is dominant,
or roof-water is a very good and sufficient source
UD supplies insufficiently, no demand of Qual. A,
roof-water is a very good and sufficient source
UD supplies insufficient water of Qual. A,
the demand of Qual. A (or A+B) is dominant
or roof-water is a very good and sufficient source
UD supplies insufficiently (of both qualities),
no demand of Qual. A
or roof-water is a very good and sufficient source
Abbreviations: rf.wa. – roof-water; trmt. – treatment; Qual. – Quality;
sp.nk. – superior networks, indicates water from networks of superior water entity
[1] it indicates that the superior water entity has the dual system.
