Conceptualizing a decentralized stormwater treatment system for an urbanized city with improper stormwater drainage facilities

Abstract

Urbanization involving replacement of previous areas with impervious surfaces and drainage channel modifications results in increased runoff volume leading to flooding and also in deteriorating the quality of the stormwater runoff. An effective and efficient stormwater management is needed in the urban areas for mitigating the impacts and overcoming the problems associated with the urban stormwater. An attempt has been made in the present study to investigate the relationships between stormwater quality and five different land uses for the Patiala city of Punjab State. Stormwater samples collected from these locations, between April 2010 and March 2011, were analyzed for various organic and inorganic water quality parameters and heavy metals. Inter-parameter relationships studied provided vital information in deciding upon the treatment units most likely to be suitable for that particular sub-watershed. Multiple regression modeling helped in assessment of water quality parameters and predicting the quality well before actually analyzing the parameters and thus aided in developing treatment schemes suitable for taking care of the stormwater quality even under worst set of conditions. The outcomes of the research study effectively contributed toward conceptualizing a decentralized stormwater treatment system that would be capable of coping with the stormwater runoff-associated problems faced by the city and can serve as a model for other underdeveloped and developing cities having improper stormwater management facilities.

Impact Assessment of Aerosol Optical Depth on Rainfall in Indian Rural Areas

“…Both natural and human activities cause air pollution in rural areas (Dey et al 2004 ). Natural sources of air pollution occur when pollutants are generated from various natural sources (i.e., animals, plants, land resources, forest fires, coal fires, dust storms, volcanic eruptions, and sand storms) and are dispersed in the atmosphere naturally (Arora and Reddy 2013 , 2014 , 2015 ; Li et al 2010 ). Solid fuel combustion (cooking and heating) as well as agriculture activities, mining (opencast and underground) activities, industrial activities (cement production and coal processing), all contribute significant air pollutants into the ambient atmosphere (Xia et al 2005 ).…”

Technical and natural conditions and operating efficiency of a municipal stormwater treatment plant

“…Good quality of treated stormwater (taking only the analysed ratios into account) also makes it possible to use it for household purposes. Other authors have demonstrated that integrated management of stormwater can generate considerable economic benefits (savings on tap water), hydrological benefits (flood protection) and ecological benefits (protection of habitats) (Mitchell et al 2007 ; Sharma et al 2008 ; Yu et al 2013 ; Tao et al 2014 ; Arora and Reddy 2015 ; Pennino et al 2016 ). In the conditions of the study, water from the retention pond can be used, e.g.…”

Hydrochemistry of drinking water sources and water purifiers in relation to epidemiological study in Hisar, North‐West India

“…The geological environment, recovery, and anthropogenic activities like domestic, industrial, commercial, mining, and cultivation, directly affect the regional quality of water (Singh et al., 2004; Zhou et al., 2020). In addition to these sources, storm water is also considered a significant contributor of pollutants to surface and groundwater (Arora & Reddy, 2013; Arora & Reddy, 2014, 2015). Contamination of surface and groundwater by these activities is a serious problem, especially in developing countries.…”
