The Kerala government in this year's vote on account has set aside more than ₹90 crore for Mazhapolima, a rainwater-linked well recharge scheme. It has worked because it has been community-driven and participatory, planning is bottom-up and led by panchayats, while the state government facilitates. It is a process-oriented programme encouraging innovation and diversity. Setting up a household system is inexpensive. As a result, groundwater levels have improved significantly in Thrissur.
