Piedmont
A waterbody in a discharge zone on impermeable strata cannot support a groundwater-recharge claim regardless of surface observations. This classification gates Panel 3 and the SROI recharge stream.
Panel 3 · Current status & early signal
PRA + site observation
Indicative
Early learning — not a long-term outcome claim
At the time of assessment, Tamil Nadu site 39 is functionally operational with visible water retention through the post-monsoon window. Community reports a modest uplift in cattle-water access; TMC is formed and active. A DiD-style outcome readout is not rendered for Phase 2 sites because no comparable baseline exists.
