Prelims Strategy

Write the water balance before interpreting a saving. If consumption stays at 60 while withdrawal falls from 100 to 80 and recoverable returns fall from 40 to 20, the consumptive saving is zero under the stated assumptions. Do not label the entire withdrawal reduction as water newly available to the basin.

Check the unit and scale of an efficiency claim. Water applied per hectare can fall while total consumption rises after expansion. A basin-level conclusion needs comparable boundaries, periods and information about return flows. Equipment cost and adoption area do not supply that evidence.

For classification, distinguish rivalry from exclusion: pumping can reduce availability to others even where access is shared. For governance, a basin is not defined by a state boundary or dam operator. Retain the qualification linking State List Entry 17 with Union List Entry 56, and keep Article 262's adjudication role separate from tariffs or municipal administration. Each statement should answer the precise physical or legal question posed.
