We present a local, self-sustaining, natural and economic way to secure a quality drinking water resource for a town or city. Most local rainfed aquifers in the environs of cities suffer from long-term contamination by chemical waste – either fertilizers and pesticides or urban effluents. We propose a process by which such aquifers can be restored to quality. This is accomplished by first changing the land use of the catchment area of local aquifers to forest, and then by a yearly evacuation of water in the aquifer till quality is restored. A model is used to estimate that, typically, by yearly evacuation of the aquifer, pollution in the aquifer water is reduced to 10% of its initial value in 5–7 years. This is an organic process to purify the water in the aquifer. We also find that the area required for this falls within 10% of the total area of the city, well within the green area norm for a city.
