Pilot study evaluates rainwater harvesting impact on groundwater recharge, suggesting improved water security in rural areas.

This research aims to assess the effectiveness of rainwater harvesting systems in recharging aquifers for improved rural water security.
Evaluated aquifer recharge through rainwater harvesting and direct injection into rural wells in Ñuble Region
Utilized piezometric data, geophysical surveys, and seismoelectric tests to characterize groundwater
Conducted frequency analysis of precipitation from 1991 to 2020 for hydrological design
The implemented rainwater harvesting systems achieved injection capacities of 0.9 to 1.4 L·s−1
Aquifers were identified with water levels ranging from 2.6 to 23 m
Findings suggest rainwater harvesting coupled with aquifer recharge can enhance rural water security and inform regional policies

Pizarro et al. (2026) studied this question.
