Demolition of unsafe buildings and structures requiring extensive modifications is more common now a days. Almost 30% of new constructions are coming up on the demolition site. Handling of demolition debris has become a challenging issue in all the developing countries including India. The growth rate in the construction sector is 1.5 times in 5 years. While the demand for aggregates is increasing day-by-day, the natural resources like sand, gravel etc. are decreasing around the world. The need for the recycle of aggregate recovered from the debris is the need of the hour to meet the rising demand. Various studies have been reported on the subject. The present study reports the developed empirical relations between the area of the building and different items of materials in the debris for the estimation of quantity generation. Experimental results on the strength of concrete for different proportions of replacement of fine aggregate recovered from the debris are presented. The study results encourage the use of fine aggregate recycle in concrete.

Thiruvaiyaru block is one of the iron affected areas in Tamil Nadu. Iron content in the groundwater of this block records in the range 1 to 4 mg/L. Sedimentary formation contributes iron to the groundwater. The relationship between total dissolved salts and other parameters have been developed. The various field oriented iron removal methods have been discussed for the water quality management. © 2017 - Kalpana Corporation.

In the present study an attempt has been made to prepare activated carbons which are capable of adsorbing a wide range of organic substances, oxidizing materials and certain heavy metals from liquids and water. Various physical and chemical activations were done to prepare activated carbons from putrescible vegetable waste which were collected from kitchens of houses, hotels, marriage halls and farmer shandy. Characterization studies like pH, pHZPC, electrical conductivity, moisture content, ash content, volatile content, fixed carbon, bulk density, specific gravity, porosity, surface area, methylene blue number and iodine number were done. Surface area analysis was done using BET isotherm under N2 atmosphere. Surface morphology was studied using SEM and SEM EDX.Finally it was concluded that the carbon (PAC) prepared from H3PO4 treatment to be the best activated carbon which could be employed for the adsorption of color from dyeing industry effluent water. Batch mode adsorption study was performed and the effluent analysis was done before and after treatment. It was obvious from the results that PAC could be employed effectively for the treatment of dyeing industry effluent water. © 2014 Sphinx Knowledge House. All rights reserved.

Domestic wastewater treatment system for a dewelling house , grey water treatment using planter bed and septic tank with root zone bed (RZB) for black water, has been experimented in a house as a zero discharge concept. Two year of operation and maintenance suggests that model is efficient for pollutant removal. System is maintenance free, and economically viable for individual houses in rural areas as well in semi-urban developing areas. Installation cost is about 0.1% of cost construction of house. Providing zero discharge concepts may be made mandatory to ease the burden on the government and to keep environment safe. © 2012 - Kalpana Corporation.

Recently, multi-village water supply schemes are erected for quality affected habitations in India. Operation and maintenance of multi-village water supply schemes require a lot of data viz: Source, pumping stations, pipe line alignment, sizes of pipes, pressure, elevation, soil type etc. Various drawings and plans are prepared rarely with geo-reference during project planning and design. For Engineers in charge of maintenance, Geo-spatial maps with the above details will help in effective operation and maintenance of water supply schemes like for planning for augmentation, identifying leakages, pollution control etc. An attempt has been made to prepare different utility maps for a multi-village water supply scheme, named Vellur and 24 habitations in Musiri union, Trichy district, India, using GIS tools. Methods adopted to prepare maps and uses of developed maps are presented. © 2006-2016 Asian Research Publishing Network (ARPN).

Detailed design and cost estimation of a sewerage system consumes a lot of time due to the involvement of various components and technicalities. Many a times, a rapid assessment of a probable cost of a sewerage system is vividly required for budget projection. As such no preliminary cost model is available for the purpose. The present work attempted to derive a preliminary cost model. Population is the main factor based on which quantity of sewage to be handled is decided. Moreover, it governs the length of sewer, pipe size etc. Keeping the population as an independent factor, an empirical relationship has been derived between the population and installation cost of the sewerage scheme from the actual data. The developed relationship will help the planning engineers to prepare a cost estimate rapidly if the population of a city is known. © 2006-2015 Asian Research Publishing Network (ARPN).

Shortage of water is a cause of concern throughout the world especially in developing and under-developed countries. India has already become water stressed country. Rainwater harvesting has been in practice around the world since ancient days. Traditional rainwater harvesting structures present exhibit the existence of such practice in India. Rainwater harvesting ponds, called as 'Oorany' in Tamil language, are prevalent and are being used for drinking purpose in part of Dindigul District, Tamilnadu State, India. Samuthirapatty is a rural village in Natham block, Dindigul district has one such pond, which was established three century back. An attempt has been made to study the hydrological and physico-chemical parameters of Samuthirapatty pond. The capacity of the pond is 23.53 million litres. Runoff potential estimation indicates that the rainfall excess works to 321.48 million litres over one square kilometre of area for the 50-year mean monthly rainfall. The present annual drinking water demand of Samuthirapatty is 23.50 million litres. Pond water is very soft with the total dissolved salts of 58 mg/L. Excess iron, turbidity and fecal coliform render the water unsafe for drinking. Pond water enjoys palatability and is the preferred choice for drinking and cooking. Promotion of point-of-use (POU) water treatment system with community education may render the system sustainable. These type of ponds may be rejuvenated and will be very helpful to ensure water security as supplementary sources. © 2006-2014 Asian Research Publishing Network (ARPN).
