Multiple scenarios were analyzed, including a baseline condition, leakage influence, and IBWT effects. Results show that leakage contributes 35 %-41 % (95 % confidence interval) of total groundwater recharge, with higher contributions in urban areas. IBWT reduces Jakarta's domestic water deficit by 62.5 % and increases leakage volume by 12 %.
