Classic Orchards - Comprehensive Water &amp; Waste Management in a 500 Plot Community

Bengaluru and many Indian cities are facing water scarcity issues due to population growth, increased food production, and overextraction of groundwater resources through excessive well drilling. Historically, India relied on groundwater as its main water source, with over 33 million wells providing over 60% of water needs. However, unsustainable usage and a lack of recharge has led to dropping water tables. The document discusses India's history with canal irrigation projects, dam construction, watershed management techniques, and the development of Bengaluru's piped water system to demonstrate how infrastructure development and population growth have impacted water resources over time. It advocates for rainwater harvesting and recharge well projects to restore local hydrology and refill depleted groundwater

Lake Privatisation

Bhargavi Rao

The document summarizes Bangalore's lake systems and the issues they face. It notes that Bangalore once had 262 lakes in 1961, but that number declined to 127 in 1986 and 117 in 2003 due to urban expansion. The lakes are interlinked in a chain and help with groundwater recharge. However, many have been leased to private companies, restricting public access. There have been protests and court cases around privatization and efforts to better protect and restore the critical lake systems.

The Rainbow Drive Story

The Rainbow Drive residential layout in Bengaluru, India faced water scarcity, flooding, and dysfunctional sewage treatment issues when initially developed. Over a decade, through tireless efforts, the Plot Owners Association implemented various water management reforms. These included banning private borewells, installing water meters and instituting water tariffs, educating residents, implementing rainwater harvesting and groundwater recharging, and improving sewage treatment. As a result, the layout became self-sufficient in water, recharging more groundwater annually than it withdraws. The story demonstrates how engaged community efforts can achieve sustainable urban water management.

How is RPC improving water efficiency?

Anton van der Plas

There is 1.386 billion km3 of water on Earth but most is unavailable for human use. Only 1.2% is accessible as surface water and over 68% is locked up in glaciers and ice caps. Most global water withdrawals are for agriculture at 70%, with 22% for industry and 8% for domestic use. However, water supply and demand are changing due to factors like climate change, population growth, increased food production, industrialization and urbanization. RPC Group uses water predominantly for cooling in the plastic manufacturing process and is taking steps to improve water efficiency through closed loop cooling systems, leak prevention, and monitoring sites in high risk areas.

Bangalore water supply resources_Schools India Water Portal_2011

Bangalore faces increasing water shortages as its population grows rapidly. The city's water supply comes primarily from two sources - 21% from groundwater and 79% from surface water sources like the Cauvery River. However, nearly half of the city's water is lost due to leaky infrastructure. While the water board treats over 1 billion liters of water and sewage daily, the amounts of sewage generated and treated water available are both insufficient to meet current demand, leading to a deficit of over 600 million liters per day. Unless action is taken to conserve water resources through rainwater harvesting, reducing waste, and other measures, the water crisis in Bangalore is expected to worsen as the population continues to rise.
