Dear Experts
I am going to do some water harvesting projects in an area with approximately 150 mm rainfall and high relative moisture. There are some land uses including rangeland and residential area in the study area.
I need to know is it possible and applicable to do water harvesting project in this area? in other words, what characteristics are required for these kind of projects? Finally, what methods can I use in this work?
Best Regards.
I suggest making use of my publication available in this web. Try also to use the FAO manual and much other literature.
Dear Seyed,
you are not indicating the purposes of your water harvesting. For domestic purposes water harvesting from the roofs and from around the residences makes sense. For animals in the grazing areas, having rainwater collected at the bottom of natural or created lows would help. For agricultural purposes there are scores of ways in which water can collect around rooting systems/areas, mostly artificially, so by design. Let us know what project/programme you have in mind.

Dear Professor Stigter.
Thank you for your kind guidance.
The goal of the project is to harvest water for drinking and domestic purposes. You mentioned harvesting water from roofs is recommended for these purposes. Is there any other method to harvest water in an area with the mentioned characteristics?
Thank you again.
Dear Seyed,
sorry to keep you waiting but I had a deadline.
I quote one source:
"Rainwater that is not captured directly, used by agriculture, or absorbed into the ground becomes surface water. Surface water harvesting includes all systems that collect and conserve surface runoff after a rainstorm or in intermittent streams, rivers, or wetlands for storage in open ponds and reservoirs. This can provide water for direct household use (treatment is generally required), irrigation, livestock, and aquaculture. Storage can also be the goal of collecting surface water, whether through open reservoirs or direct infiltration to aquifers below ground. Storing water in an aquifer conserves water better as it prevents evaporation, unlike open reservoir systems".
This shows that rooftop harvesting is used overwhelmingly. In case that this is not possible the above applies but the water is more difficult to collect for drinking purposes and might need more treatment due to contamination at the surface used.
There is indeed very much information on the internet you can obtain through free use of Google, that is one of the best.
Success, Kees
Dear Seyed,
I just came across the attached information.
Kindest regards, Kees
