Prevention of pollution in rivers and water bodies involves proper treatment of the sewage, drainage and other liquid effluents joining the river streams,as well as maintaining the natural river flows which have been diminishing due to the excessive drawl of river stream waters for the purpose of drinking water schemes, irrigation and some industrial uses, where ground water could be used, if available. Sub-soil ground water levels have also been going down on account of the excessive population growth in the last six decades, resulting into more and more dependence on river waters. This situation needs to be changed by enhancing the rain water harvesting and ground water recharge volumes with innovative and special measures so as to return to minimum drawl of river waters for drinking and other uses. The proposed measures could be summarized as follows. (i) Restoring Natural River Flows would involve (a) Reducing the surface water Drawl to a minimum. (b) Optimal Utilization of Ground Water for Drinking Water Supply, Irrigation and other uses. (c) Enhancing River Flows through improved surface drainage. (ii) Synchronized Water Supply and Precipitation Storage-cum- Recharge Systems in Water Scarcity areas. (a) Water Supply Schemes equipped with simultaneous rain water harvesting structures. (iii) Optimal Ground Water Recharge and Improved Drainage by innovative and special methods such as (a) Optimal Ground Water Recharge through Village Ponds, equipped with precipitation overflow diversion and recharge system. (b) Waste Water Drainage Treatment at discharge points before outfall into rivers.

Ground Water Recharge

Water demand increases as population increases leading to overexploitation of water resource. Consequently, there is need for improved water resources management complemented with rain water harvesting within the catchments. This study sought to assess land suitability for surface runoff harvesting using geospatial techniques. Land use/land cover maps of the area were derived from Landsat image. Land use and soils data were used in generating curve number map of the catchment. Lineaments greatly affect the storage depending on whether runoff is for surface storage or ground water recharge purposes. As a result, ArcGIS was used in delineating the lineaments from Digital Elevation Model (DEM) of the catchment. Further, using weighted overlay the catchment was grouped into categories of restricted, not suitable, moderately suitable, suitable, or highly suitable. The study found that forest, agriculture, and built-up areas occupied about 39.42%, 36.32%, and 1.35% of catchment area, respectively. A large part of catchment was found to have curve number range of 82–89. About 50% of the catchment was found to fall within suitable and highly suitable categories. This implied that a great potential exists for rain water harvesting within the catchment.

Peak Summer

Groundwater occurring in the shallow aquifers is highly saline and is not suitable for drinking. Fresh potable ground water is occurring at great depth (245–325 m bgl). Occurrence of fresh ground water at deeper aquifers restricts large scale groundwater development, because it is beyond the economic capacity of common people. Source of drinking water is mainly Government owned hand pump fitted tube wells. Approximately per 70 households only one such tube well has been allocated. Many of these tube wells are yielding very less quantity of water during peak summer. Hence, the island is suffering from potable water scarcity especially during summer for around 4-5 months. Water supply is available in very few villages. Almost all the households are having one or two ponds. Most of the ponds are dried up during summer. Therefore, people in the island are facing water shortage round the year. The island receives very good precipitation (1900 mm) during monsoon. Major quantum of rainfall is lost as surface run-off to the sea or rivers. If this rain water run-off can be arrested and stored, island may be developed in many ways. There is a vast scope of Rain Water Harvesting (RWH) in Sagar Island. Water conservation can help to minimize the huge monsoon run-off. Roof top rain water harvesting can solve the drinking and domestic needs of the people of Sagar Island. In this context, harvesting and conservation of roof top rainwater during monsoon in storage tanks and ponds were explored, so that the same can be utilized in the lean periods. Present study has aimed to understand total amount of water may likely to be available from the concrete roofs of different existing buildings like public offices, schools, guest houses and individual houses as well as household ponds. At present, total water requirement of Sagar island in peak summer (4-5 months) for drinking and domestic uses is around 1589947.50 cu. m. Total amount of rain water be conserved through small household ponds (12418) and concrete roof tops (3194) is 3692853 cu. m. of which ponds contribute 3588976 cu. m. water and concrete roof tops used to contribute 10,38,77 cu. m. water. Thus, this conserved rain water could able to benefit in catering 492380 people (i.e., more than double of present population) of Sagar Island for five months in peak summer for drinking and domestic uses.

The proposed system, helps to increase ground water table level to decrease the water crisis encountered by the people. The rain water harvesting system implemented by the government was a good system by the way but very less monsoon and unpredictable rain has made it unreliable for water table recharging. But an average household of 4 uses nearly 220 litres for bathing and nearly 200 litres for cleaning clothes and utensils per day all the water goes down for the sewage. This project aims in segregating these 400 litres of used water. By collecting all the used water in house and finding out its turbidity using led and photo detector. If water is turbid contents it is discharged into the sewage if the water is not turbid then the water is filtered using corn cobs and then diverted into the rain water harvesting system. This way at least 30 % (120 litres) out of the 400 litres of the used water can be diverted into the rain water harvesting system. When calculated for a month nearly 3600 litres can be recharged into the ground. The water diversion can be done with the help of a valve controlled by a solenoid. These are connected to the microcontroller to control all the process and send to Wi-Fi module.
