Conservation of Water Resources
It is always better and easier not to waste than to accumulate. The same principle works too when it comes to the issue of conservation of water resources. We all know how precious water is for everyone; still we do not take any initiative for the conservation of water resources and waste it in futility. Even storing water cannot be a good solution for the water crises in India, because of many reasons. Storage dams lose their capacity because of sedimentation. The chances of infection and thereby rampant maladies are also very high. Hence, it is better not to waste water and actively promote conservation of water resources.
The conservation of water resources can be practiced in all the sectors of water usage. The major sectors of water usage where conservation of water resources can be implemented are domestic, irrigational, and industrial sectors.
Conservation of Water in House
The domestic sector is such a sector where even with little care an effective conservation of water resources can take place. Water shortage is an age-old problem of rural India, particularly in the drought-prone areas and in the dry seasons. Only rain water harvesting can offer no permanent solution. Conservation of water resources must be done in the domestic level too.
Almost half of the domestic water is used for bathing and cooking. The waste water of these processes is not that much polluted. With a little care and treatment to remove solids and the odour, this water can be utilized once again for flushing purposes in the lavatories and urinals. The effluent from the toilets and bathrooms can also be used for purposes such as gardening and storage for fighting fires and so on. Thus, almost a zero affluent situation (perfect zero affluent utility is not possible for anything on the earth) can be created in the domestic sector. If we try a little, and try sincerely, we will be successful in the domestic conservation of water resources.
Conservation of Water in Irrigation
The conservation of water resources in the agrarian sector must effectively take place in order to save water in the larger scale. Irrigation is the largest guzzler of water resources in India. Here, too, rainwater harvesting can offer a good solution but not a permanent solution, and conservation of water resources must be taken care of. Conservation of water resources, if done, will be quite rewarding.
Irrigational tanks often go out due to lack of care. If these tanks are renovated, they can significantly contribute to the water required in agriculture. A good amount of water is lost in while conveying from reservoirs through canals and field channels. Substantive loss of water also takes place while applying the water from canals to the field. By improving irrigational efficiency and by implementing proper management, these can be minimized. Seepage losses too must be prevented for a better conservation of water resources. The water drained out from the agricultural farmhouses can also be pumped back for future uses.
Conservation of Water in Industry
The conservation of water resources in the industry is important because the water requirement in the industrial sector is second to only the water usages in the agrarian sector. Several things can be done for an effective conservation of water resources in the industrial areas. Review of alternative production technologies and procedures will encourage conservation of water resources. Ensuring sound plant maintenance practices and good house keeping will minimize spills and leaks and thus will promote conservation of water resources. The treatments also should be optimized in order to achieve maximum recycling and reuse.
