Global Warming Issues—Need for Sustainable Drainage System in Urban Areas—Green Construction Technologies

Abstract

The increasing population pressure on land in urban areas also adding the pressure on available fresh water sources, urban green spaces, biodiversity, and also on air and eco system. Another important issue of concern is the safe disposal of the ever-growing magnitude of urban waste. These key issues are important to be re-thinked with basic urban infrastructure planning, housing, transport, system, health infrastructure, and other allied civic amenities, required. All these issues necessitate a realistic approach to environmental policy with the basic urban planning of town and cities. The urban population of India as per 2011 Census was 377.10 million, with an average growth of 31% over the last decade, and accounting for 31.16% of the country’s total population. This is projected to be reach to 600 million by the year 2030⁽¹⁾. Thus in, the developmental policies decisions shall be multifunctional and participatory, taking into account the, environmental and other related issues and concerns of citizens. India is facing a typical problem of ground water table falling at a fast rate due to reduced recharge, and unplanned water withdrawal for agriculture and industry. Permeable pavements, if adopted for walkways, parking lots, can help in improving recharging of rainwater. This paper discusses technical information on the application, and necessity of pervious concrete pavements in urban areas, along with many of the environmental and economic benefits of using pervious concrete.
