Roof water harvesting is being widely promoted as a panacea for the growing drinking water crisis in India and many underdeveloped and developing countries. This article analyzes the scope, physical feasibility, and economic viability of roof water harvesting systems across classes and under different physical and socioeconomic situations. This article argues that roof water harvesting systems (RWHS) are not alternative to public systems in urban and rural areas of regions receiving low rainfall. Hydrological opportunities for RWHS are very poor in urban and rural areas. The systems offer very little scope in ensuring domestic water security for urban housing stocks of low- and middle-income groups. At the same time, they offer tremendous potential for independent bungalows having large roof area. However, their physical feasibility is very poor in urban areas. Their economic viability as a supplementary source of domestic water supply seems to be poor in urban areas, when compared to augmenting the supplies from the existing public systems. The incredibly low rates charged for domestic supplies by urban water utilities and government subsidies for RWHS would only lead to the urban elite increasing their access to water supplies, while the burden on water utilities would remain unchanged. This will lead to greater inequities in access to water supplies. At the same time, in rural areas with dispersed populations and hilly areas, RWHS may be economically viable as a supplementary source to already existing public water supply schemes. But as its impacts are not likely to be uniform across classes, government subsidies are not desirable. In hilly regions receiving high rainfalls, government investment for community water supply schemes could be replaced by heavy subsidies for installation of RWHS.

A study carried out in four villages in Banaskantha district of Gujarat estimated that 60 per cent of the net farm output generated through groundwater use in agriculture came from dairying. Tubewell irrigation supports three-quarters of the farming household income in these villages and, strangely, this share is larger for water buyers and farm labourers than for tubewell owners. This is despite the fact that tubewell irrigation costs have soared rapidly with depleting water tables. Despite the high costs and depleting water tables, irrigated areas have increased steadily, making livelihoods even more precariously dependent upon sustainable groundwater management.

North Gujarat is naturally endowed with one of the richest alluvial aquifers of India but its uncontrolled exploitation for irrigation has resulted in many undesirable consequences. A major hydrological opportunity for rejuvenation of the aquifer system is provided by the availability of unutilized flows from Narmada basin. It is proposed to divert this water to north Gujarat through the Narmada main canal, and use the existing canal networks and village ponds and tanks in the region to activate a decentralized recharge process. This paper examines its physical and economic feasibility. An evaluation of two recharge scenarios in north Gujarat shows that using pumped water for recharging outside the designated command area may prove to be an uneconomical proposition, unless there is substantial increase in the productivity of water. Recharge within the command would be much more economical.

The analysis presented in this paper shows that in water-scarce regions of India, run-off harvesting does not offer any potential for groundwater recharge or improving water supplies at the basin scale. The issues are many: (1) Water harvesting in the “closed” basins have downstream negative hydrological impacts. (2) Due to high inter-annual variability in rainfall and therefore run-off, during drought years the water harvesting structures have become highly unreliable, whereas an attempt to capture run-off during wet years would remarkably increase the unit cost of harvesting water. (3) In closed basins, intensive water harvesting would lead to negative welfare outcomes due to high negative externalities at higher degrees of basin development. (4) Even at the local level, physical efficiency of water harvesting is likely to be poor, mainly due to groundwater-surface water interactions and the poor storage capacity of hard rock aquifers underlying most of the water-scarce regions. The artificial recharge systems in natural water-scarce areas in India are economically unviable. Also, the much talked about virtues such as promoting equity in access to water, social justice, water security for the poor, and realisation of greater economic value from the use of water, can be hardly achieved through water harvesting programmes in water-scarce regions, as practised today.

The economic value of water should be markedly higher in water-scarce regions than in water-rich regions. Similarly, then the incremental return per unit of land should be higher where land is scarcer. These hypotheses are tested by comparing the situation in western Punjab, which is land-rich and naturally water-scarce and eastern Uttar Pradesh which is land-scarce and water-rich. Our regression analysis shows that every extra unit of water diverted for agriculture generates more economic surplus in western Punjab while every extra unit of land put under cultivation generates more economic surplus in eastern Uttar Pradesh. Hence, transfer of water from a water-rich, land-scarce region to a water-scarce, land-rich region for agriculture might result in the realization of higher economic value.
