Hi Guys,Fascinating. Why the stepped shape of the excavation? I imagine all the vertical sides will collapse and become 45 degree slopes as nearly always happens (unless the clay soil is real firm). Why not a pond with greater surface area
On our tiny acreage farm (1.86 acres), we recently finished building a
3 stepped 3825 sq.ft. sized pond with a max depth of 22 ft. We had
three goals:
1. Store water for irrigation needs during the dry-seasons (post
monsoon and then pre-monsoon)
2. Conserve the constructed pits / wells / dams / hedges / whatever
structure
3. Storing run-away water / Retrieving stored water must be doable
using as little energy as possible
We rented out a backhoe excavator (JCB-3CX) and two tipper tractors
for this job.
http://wiki.sunson.in/rain_water_harvesting explains the design in
terms of satisfying these above three goals.
Please feel free to let out your comments!
Cheers,
