If the source of the pollution is sewage either from a treatment plant or
from individual septic tanks or cess-pits I believe that the technique of
disposal and reuse by means of subsurface drip irrigation may be useful for
you. It is not essentially cheap but it is very much lower in cost than
tertiary treatment of the sewage. If you have sandy soils, as I suspect,
this can be a very practical solution.
I suggest that you check our web site at http://www.rootguard-geoflow.com
which has a lot of technical information.
We do have an Israeli licensee who is listed on our web-site. They are very
new in this wastewater disposal and reuse technology so we would be pleased
to work directly with you on the technical deliberations and have them
supply you because that would be much cheaper than importing from the U.S.
or Spain. If you like what you see on the web site please contact me directly.
