From the experimental results of 4 Bo Bo was found to be effective in the treatment of most wells with floors filter (DIN gravel stone) with 6-day water catchment scale.
The results showed that the 4 ponds ponds are most effective in the treatment pond with a filter layer (soil, gravel, stone), the rate of water storage for 6 days.
From the experimental results showed that both 4 pond pond with efficiency of most is a pond with filter layer (soil, gravel, rock) rate of water retention 6 days.
