There are 39 temple tanks in the city of Madras, most of which have been dry for the past one decade due to rapid urbanization and continuous withdrawal of groundwater. Out 39 temple tanks one tank belongs to Mylapore Temple which is within Madras city and second one belongs to Thirupporur Temple which is out of city have been selected to compare the status of the temple tanks. Thirupporur Tank has been taken to find the reason for having water throughout the year. Then the Mylapore tank (within the city) has been taken and studied in detail. The study found the reason for the dryness of urban tanks. It also revealed the methods to rehabilitate and thus to re-establish the hydrological role and possible multiple use of the tanks. The study analysed both the quantity and quality aspects of the tanks.Keywords

Water recycling and reuse is a major component of contemporary water management strategies as the world faces increasing fresh water demand and problems associated with disposal of wastewater. The use of soil aquifer treatment (SAT) is the most common method for Artificial recharge as it does not require high technology levels. It is simple and cost effective to operate and is capable of achieving extremely good quality treatment of the recharged water. However, the success of this method can be limited by clogging issues affecting the overall performance of these systems. This paper deals with the literature review of SAT Technology with soil columns study using primary as well as secondary effluents with related removal efficiency of different pollutants. The use of soil columns test for the study of SAT is a way to better understand removal mechanisms in soil, hence helping to understand SAT full scale performance and eventual risks. The main conclusion of the review is that the soil columns can be effective on removal of the major contaminants from wastewater. The use of soil columns prove to serve the purpose of removal relates with the configuration of the columns, as well as the soil type affecting infiltration rates and the development of clogging issues.Keywords

Groundwater use is increasing all over India and Chennai is not an exception. A good possibility exists to recharge artificially the excess treated wastewater through Soil Aquifer Treatment (SAT) and use the recharged water for purposes other than drinking. Soil column experiments were performed, in order to study the ammonia, nitrite and nitrate reduction from Real Secondary Treated Wastewater (RWW). SAT was simulated in four 15 cm long soil columns packed with soils of Sandy Clay Loam (SCL) texture collected from Anna University Sewage Treatment Plant (STP), Chennai, India. Soil Columns were ponded with wastewater to a depth of 2.5 cm above the soil surface and operated for a period of Ten cycles under 4 different alternating wet and dry cycles, 0.25 day wet/1.75 days dry (R1), 0.25 day wet/2.75 days dry (R2), 0.25 day wet/3.75 days dry (R3) and 0.25 day wet/7.75 days dry (R4). The effect of wetting and drying periods on SAT ammonia removal performance was assessed comparing ammonia, nitrite, nitrate nitrogen and TDS rates. The removal of ammonia was through nitrification process which is found to be a dominant removal mechanism of nitrogen. Nitrification differed according to the different drying cycle’s time with fixed flooding period. When the reduction performance achieved with different drying cycles were compared, it could be seen that longer drying periods with R3 column yielded with the least nitrate value of 0.58 mg/l. From this study, it was found that with the fixed wetting period, maximum drying period is required for nitrate reduction and minimum drying period is required for TDS reduction.Keywords
