System proposed in this paper is the planned filtrating penetration system to harvest the surface runoff like storm water into our designed unit in order to increase the natural level and replenishment of ground water resources. Ground water recharge is increasing in popularity as ground water resources are being depleted due to excess of water extraction of water from boreholes in the urban areas. Although the primary objective of this technology is to preserve or increase ground water resources, this kind of artificial recharge has been used for many other beneficial purposes. These include additional treatment (through soil filtration) and conservation or disposal of treated wastewater or floodwaters, storage of water to reduce pumping and piping costs as well as temporary regulation of ground water abstraction. Furthermore water quality can be improved through the removal of suspended solids via soil filtration (see also aquifer treatment) or through the dilution with naturally occurring ground water.

Water And Wastewater

The primary problems concerning water resources in Sri Lanka are the depletion and degradation of the resource caused by various anthropogenic activities. Surface inland waters in urban areas are polluted heavily with domestic sewage and industrial effluents, and in rural areas with agricultural runoff. With regard to ground water in certain areas of the dry zone, there is a high fluoride content and in hard, rocky, alluvial areas, there is a high concentration of iron. In urban over-crowded cities, there is biological contamination of ground water. Over-utilization, particularly through tube wells, is another major problem affecting ground water resources in Sri Lanka. Oil spills, dumping of waste from ships, coral and sand mining, and industrial activities are the main causes of marine pollution in the country. Except for pipe-borne water supply, irrigation and hydropower schemes, in general water resources in Sri Lanka are managed very poorly. Regulations are available to control most water related problems but enforcement of these regulations is lacking. The ultimate result of degradation and depletion of water resources is the increasing health hazards. Water-borne and vector-borne diseases are prevalent, particularly amongst urban low-income communities with poor sanitary facilities and drainage. Despite government initiatives and legislation, very slow progress has been made towards combating water pollution. This paper examines the most significant water and wastewater related issues in Sri Lanka and their controlling mechanisms.

Surface Water Resources

The calculation of water resources is the fundamental basis for legitimate utilization, effective protection, optimal configuration and optimal dispatch of water resources. Affected by climate change, economic development, and population expansion, the amount of water resources in Fengtai district, one of the central urban areas of Beijing, has undergone major changes. By comparing the results of the second investigation and evaluation of water resources (1956-1998), the paper analyzes the dynamic changes and causes of surface water resources, ground water resources and total water resources in Fengtai district in recent 61a (1956-2016). The results show that the surface water resources of Fengtai district in recent 61a is 37.978 million m3, which is 2.572 million m3 less than the previous investigation; the ground water resources is 92.959 million m3, a decrease of 13.848 million m3; the total water resources is 104.981 million m3, which is 13.830 million m3 less than the previous investigation. The gradual reduction of regional atmospheric precipitation is the main cause of the decline in surface runoff and rainfall infiltration recharge. At the same time, the continuous water-cutting of Yongding River (the biggest inflow river in Fengtai) since 2000 and the anti-seepage project implemented in 2010 further reduced the infiltration of river infiltration .

Ground water is one of the most important natural resource next to air being essential for life. Quality of ground water depends upon natural process, such as wet/dry condition, salts, many geogenic and anthropogenic activities. Among all contamination ground water is more susceptible to microbial contamination. According to WHO report about 80% of all diseases in human being are caused due to drinking water contaminated by bacteria of faecal origin. Various water born diseases are prevalent in Ujjain like typhoid, dysentery, jaundice, amebeosis, colitis etc. Purpose of the study was to assess the bacterial contamination of faecal origin in ground water resources of urban area of Ujjain. For this ground water samples (well, bore well and hand pump) were collected from 6 sub areas of Ujjain city. For the assessment of bacterial contamination of faecal origin H2S strip test of Manja,et.al.(1982) was used. Results clearly indicated that bore well water was found to be safe for drinking, domestic and other purposes.

Wastewater Use

Climate change and wastewater control are one of the foremost demanding situations for Indian cities. Urbanization and unparalleled growth of cities across India continue to create immense pressure on land and water resources. This uncontrolled growth continues to produce growing volumes of wastewater. Climate change, impacts inclusive of, intense storm events in summer time or extended moist periods in wintry weather are quite visible in India. In urban and peri-urban areas, wastewater use for agriculture is an emerging precedence. Due to susceptible enforcement of regulatory, most of the wastewater generated is permitted off untreated/ partially treated. While many previous studies have checked out the global modifications and associated impacts of climatic variations on water resources, few have targeted at the evaluation of the particular effects and adaptation priorities for water systems in towns. Proper reuse of wastewater for irrigation will significantly lessen the shortage, offer a sustainable water source, improving farming productiveness, lessen pollution, generate livelihood potential for low earnings city households along with contributing to their each day food needs. There are tradeoffs which need to understand which includes problems to individual's health, and surroundings. Through suitable treatment methods, water users' cooperatives, policy shift and the introduction of market based approaches, treated wastewater use in agriculture can be enhanced and all associated risks can also be curtailed. This chapter focuses on use of treated urban wastewater and its management for agriculture in selected Indian cities.
