Iv) Piped Water Supply Schemes: These are generally for towns or big villages (urban areas). In these schemes house connections are given and the consumption is charged. The source may be in the locality or a distance source ( like Rajeev Gandhi lift canal for Jodhpur). C. R) are constructed for the distribution of water through the distribution mains. First of all the raw water is treated by all means including disinfection (most important). Then pumped to ESRs and then distributed either for the whole day or at certain fixed time.

Some of the water is always stored for fire fighting. As there is a depletion of ground water, and uncertainty of rainfall due to global warming and other reasons, it has become very difficult to maintain the urban water supply schemes these days. 1 Quality of Water Quality of water is the most important aspect. There are international and national standards for the quality of water to be supplied for human consumption. The state governments may have a slight relaxation in the standards depending upon the local conditions but in general they are the same throughout the country.

Some rivers have surplus water and some are deprived of it. They may be linked with each other, with care of possible environmental impacts. We have developed such ways and means to assess the environmental impacts of any project (discussed in detail in chapter no. 7) It is not wise to reject such ambitious and important projects for some unquantified fears. On the other hand as it is against the nature’s present system, so one has to be very careful in considering the overall cost and benefits ratio.
