[55] The various water and sanitation policies such as the "National Environment Policy 2006" and "National Sanitation Policy 2008" also lay down wastewater treatment regulations.
In spite of adequate average rainfall in India, there is a large area under scarce water conditions/drought-prone. There are lot of places, where the quality of groundwater is not good. Another issue lies in the interstate distribution of rivers. The water supply of 90% of India's territory is served by inter-state rivers.
Embankment dams come in two types: the earth-filled dam (also called an earthen dam or terrain dam) made of compacted earth, and the rock-filled dam. A cross-section of an embankment dam shows a shape like a bank, or hill. Most have a central section or core composed of an impermeable material to stop water from seeping through the dam.

Map of India based on survey of rivers of India.. The Indian rivers interlinking project is a proposed large-scale civil engineering project that aims to effectively manage water resources in India by linking rivers using a network of reservoirs and canals to enhance irrigation and groundwater recharge and reduce persistent floods in some parts and water shortages in other parts of the country.
Developing sustainable water supply systems is a growing trend, because it serves people's long-term interests. [16] There are several ways to reuse and recycle the water, in order to achieve long-term sustainability, such as: Gray water re-use and treatment: gray water is wastewater coming from baths, showers, sinks and washbasins. If this ...
India accounts for 18% of the world population and about 4% of the world’s water resources. One of the solutions to solve the country’s water woes is to create Indian Rivers Inter-link.c [2] India has been successful in creating live water storage capacity of about 253 billion cubic meter(BCM) so far.
