Abstract:Human activities and urbanisation deplete water resources. Due to rising home waste, sewage, industrial waste, etc., freshwater bodies are polluted. Urban and semi-urban areas produce lots of sewage. Sewage treatment and disposal are global issues due to a lack of cost-effective methods. Aerobic and anaerobic therapy technology has improved. Low-cost rootzone sewage treatment. Conventional sewage treatment plants cost Rs 12 per 1000 litres to operate and maintain. Due to expensive treatment costs, sewage is directly dumped into rivers or surrounding water bodies, contaminating society's water sources. Small towns cannot use traditional methods. Sewage treatment must be cost-effective. Root Zone Technology (RZT), which uses plants to treat sewage, is a low-cost alternative. Root Zone Technology was tested for sewage treatment. Pilot reactors explore diverse plant species. Tap water irrigated reactor-planted species. India needs to fully exploit this technology for sustainable growth
1. Introduction:Rapid urbanisation in a growing country like India has led to a rise in the demand for water used in a wide range of human activities. The water supply and demand in many urban areas have been impacted by population growth. Domestic water supply, industrial production, irrigation, power generation, animal supply, recreation and leisure, breeding of aquatic species, dilution and transport of trash, etc. are all examples of developmental activities that rely on water (IWWA,2007). Water treatment is a common necessity in both residential and commercial settings. About 80% of the world's freshwater consumption is the result of residential wastewater. The lack of readily available clean water is one of India's most pressing environmental problems. India is experiencing a double whammy of inadequate infrastructure and rising urban populations as it attempts to make the leap from poor nation to developed power. This has resulted in two issues that feed off of each other: water scarcity and sewage overflow. By 2050, it is predicted that almost half of the country's population would reside in urban areas. As a result, the demands placed on the city's infrastructure and public services have increased at a faster rate than they have grown. Sewage is often discharged into nearby bodies of water or let to spread across open fields, making for poor wastewater treatment in rural areas. Class I cities and class II towns with populations over 50,000 are anticipated to generate 38,254 MLD (million litres per day) of wastewater. Only 31% of wastewater generation is treated, which amounts to 11,787 MLD of municipal wastewater treatment capacity (CPCB, 2009). For this constructed wetland uses natural treatment system with substrate materials like sand or gravel planted with vegetation[6]. Reed bed is the natural amd cheap method of treating domestic, industrial and liquid waste. Reed bed is considered as an effective and reliable secondary and tertiary treatment method where land area is not a major constraint [9]. 1.1 Background:Approximately 99.9 percent of domestic sewage is water, with the remaining 0.1 percent being organic and inorganic materials, suspended and dissolved particles, and microorganisms. The remaining 0.01% is the source of the water contamination or pollution that requires purification. The characteristics of wastewater are dependent on the final destinations of the transported water. The composition of wastewater is affected by factors such as the local climate, the economy, and public hygiene practises. Smaller urban centres cannot afford to use the traditional approaches. Therefore, a reliable and inexpensive sewage treatment system is required.
