Dear Noom,
One of the sketch is a simple idea to use net to cover the swimming pool from falling leaves. The idea is to erect poles from the filtering ponds as intermediate support. The net will be hung in a cantilever and can be pulled back using pulley. I will explain the idea to you when we meet.
The other sketch is about rainwater harvesting using down pipe. This is a very cheap way of doing first-flush which is essential to all rainwater collection. Again I will explain the technique to you. These are methods that we can teach villagers who drink rain water.
By the way, many thanks for your consistent SR report which will be very helpful for training new contractors.
See you later at AGLC,
Thanks
