Hello Sir, 

We are from Banglore. Kids have asked for pool on our terrace , but me and my husband thought to involve them in its designing also. At the same time, we don't want wastewater.

In this pandemic time, we actually started studying permaculture. With that little bit of information , we have come up with this design. We are attaching the plan. Kindly give your precious input 

Thanking you Sir
