OK, but the potable water system's leaking isn't going to contaminate
the waste water. It could wind up back in the aquifers though, after
being contaminated by the drainage.
So the problem is in the waste water drainage system and the
contamination is occurring before any opportunity for treatment can
occur. On the other hand, if the potable water delivery system wasn't
so permeable, it would be as subject to contamination from without.
One of the two will have to be given priority, but the renovation of
both water delivery systems is called for. Probably the waste water
drainage system should be addressed first, since it may be
contaminating the aquifers directly and indirectly.
I would think International funds would be available for remedying
this kind of health based mechanical problem.

Glad to hear it. It looks like a beautiful country from what I've seen
from afar.
