Very interesting, Suraj, and quite a well done write-up. I also do not see how the straight sides will stay that way. Surely they will wash into gentle slopes. Another consideration...what if someone falls in. Can they he/she get out or would drowning possibility be high...esp a small child? That would worry me. Even a dog would have a hard time climbing out without a slope.

Just my first impressions, hope they're useful, Lisa

Hi Guys,

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,

-Suraj
