‘Water Related Problems’ Encountered In Zoological
Parks And Their Solutions
1. Water Logging
A. Can be resolved by suitable grading
2. Waste Water Disposal from Wet Moats and Enclosures
A. Recirculation after treatment
B. Used for irrigation of lawns and plants with the
help of pumps
3. High Water Table Areas
A. Planting of species which survive in high water table areas and those
having high evaporation rates
4. Low Lying Areas
A. Suitable grading is required to be done to ensure accumulation of water
in predetermined areas.
B. Raising of useable areas by initial filling, if possible, largely through
soil acquired from within the site.

Run off from Zoological parks can be reduced considerably by:
A. Ensuring the existence of a permanent vegetative groundcover.
B. Maintaining minimal surface gradients (varying from 2% to 4%). If natural
topography has steeper grades than the sheet flow or channelised discharge
should be retained within the site.
C. Maximum contact between flowing surface water and soil.
