Grey Water Treatment Unit – A Case Study of Shrirampur Grampanchayat R. T.

Parbat Lecturer Civil Engineering Department Government Polytechnic Nagpur, parbatdk@gmail.com Abstract: This paper proposes a grey water recycling system that will provide recycled water specifically for bathrooms. Grey water is wastewater from showers, baths, washbasins, washing machines and kitchen sinks. A high volume of water is taken from the environment for human use. Demand for water is rising because the population is increasing, lifestyles are changing and the impacts of a changing climate are becoming clearer. It differs from the discharge of toilets, which is designated sewage or black water to indicate it contains human waste. In contrast, the amount of human waste present in grey water is so small and so degraded by the soap that its return to the environment requires no systematic wastewater treatment. Water used in hand washing and bathing generates around 50-60% of total grey water and considered to be the least contaminated type of grey water. This case study was performed by collecting samples of bathroom grey water from three zones of the Shrirampur Gram Panchayat in Pusad City.. Keywords: Grey water, black water, wastewater treatment 1.0 INTRODUCTION 1.1. Need for Alternative Sources of Water in India: ndia is facing a water crisis and by 2025 it is estimated that India's population will be suffering from severe water scarcity. Although India occupies only 3.29 million km2 geographical area which forms 2.4% of the world’s land area, it supports over 15% of world's population with only 4% of the world's water resources. With increased population growth and development, there is a need to critically look at alternative approaches to ensure water availability. Conventional groundwater and surface water sources are becoming increasingly vulnerable to anthropogenic, industrial and natural pollution. Groundwater sources are being over extracted, resulting in leaching of fluorides and nitrates. Surface water bodies are becoming susceptible to unregulated industrial discharge resulting in increased eutrophication and algal blooms. To resolve the problem, there is a need to look for alternative water resources. These include rainwater harvesting, wastewater reuse and desalination. Concerns over desalination include mineral decomposition of potable water and limited inland availability. Additionally, limitations of rainwater harvesting include the quantity and quality that may be available, given the increased threats of global warming and air pollution. 1.2. Why Reuse Grey Water? Water is becoming a rare resource in the world. It is therefore essential to reduce surface and ground water use in all sectors of consumption, to substitute fresh water with alternative water resources and to optimize water use efficiency through reuse options. These alternative resources include rainwater and grey water. This project will focus on grey water treatment and its use as an alternative water resource in a housing society. Grey water is commonly defined as wastewater generated from bathroom, laundry and kitchen. Due to rapid industrialization and development, there is an increased opportunity for grey water reuse in developing countries such as India. 2.0 BACKGROUND OF CASE STUDY REGION Pusad is a city and a second largest municipal council in Yavatmal district after Yavatmal of Vidarbha region in the Indian state of Maharashtra.
