Jakkur lake and Rainbow Drive stories
The document discusses water management practices in Rainbow Drive, a residential community in Bangalore. It describes how the community historically relied on groundwater from borewells but faced increasing water insecurity as borewells dried up. In 2008, a water reform effort began, including installing water meters, banning private borewells, educating residents on water issues, and investing in rainwater harvesting. Tariffs were increased over time to cover costs. These efforts led to a reduction in per capita water usage from over 250 LPCD to around 150 LPCD, despite increased occupancy. The community also began reusing treated wastewater for farming.
Grey water recycling
Grey water recycling involves reusing water from bathroom sinks, showers, tubs, and washing machines in home applications like landscape irrigation. While grey water contains grease, hair, and dirt, it is generally safe for irrigation use as it has not come into contact with excreta. The benefits of grey water recycling include recharging groundwater, using nutrients in grey water to help plants grow, and reducing energy and water bills. However, grey water recycling can spread disease if not implemented correctly and stored grey water may develop odors after 24 hours. It can also damage soil through salt buildup over time.

List of Water Management/Saving Methods for Apartment Construction Plan in chennai
1. Recharging Ground Water in Apartments
Water is essential, and it is a finite resource. Groundwater recharge is one method of water management that can help ensure an adequate water supply for future generations. Groundwater recharge occurs when water from the surface, such as rain or melted snow, seeps down into the ground and replenishes groundwater supplies. This process can happen naturally during rain, or it can be assisted through artificial means. Artificial groundwater recharge is a process whereby water is deliberately infiltrated into shallow aquifers to increase groundwater quantity. This can be done through various methods, such as injecting water into the ground or using percolation pits. The volume of water being abstracted from an aquifer over the long term mustn’t exceed the volume being recharged; otherwise, groundwater supplies will dwindle.
2. Greywater System in Apartments
Looking to save on your water bill? Consider using greywater in your home. Greywater is wastewater from non-toilet plumbing fixtures, like sinks, washing machines and showers. This type of water is generally easier to recycle than blackwater, because it contains fewer contaminants. The method and standard of treatment will depend on the size of your system. To avoid confusion with potable water, make sure all pipes and supply points in your greywater system are clearly labeled. With proper care, a greywater system can help you save up to 40% on your yearly water bill.
3. STP System/ Wastewater Recycling
Wastewater recycling is crucial for preserving our water resources. There are two main types of wastewater – greywater and blackwater. Greywater is easier to treat and recycle than blackwater, which contains harmful bacteria that can cause disease. In order to save our communities from the dangers of raw sewage, one should build wastewater treatment plants and enforce laws against its release into the environment. These treatment plants help us recycle blackwater, making it safe to use again. In recent years, it has been evident that there has been an increasing interest in wastewater reuse as a key part of water conservation efforts. If your society banded together to invest in a sewage treatment plant (STP), it could mean an end to water scarcity and the recycling of water 365 days a year. To make this happen, you would need to get consent for operation from your municipal corporation and employ qualified staff to oversee standard operating procedures. However, if you invested in an eco-friendly STP that uses anaerobic methods and requires little energy, mimicking natural processes, then you could make a huge impact without using diesel or polluting the environment.

Rainwater harvesting 075 bar045
- 2. WHAT IS RAINWATER HARVESTING? Process of conservation of rainwater running off from rooftops, open grounds etc. for later use By means of collection, storage, conveyance and purification One of the simplest and oldest methods of self-supply of water for households, and residential and household-scale projects Water collected is redirected to a tank, reservoir with percolation seeping down and restoring ground water
- 3. WHAT ARE THE PURPOSES OF IT? Rainwater free from chemicals and industrial refuse is the best way to make freshwater available Process infused houses are self- sufficient making the method economically viable Reduces exploitation of natural resources like groundwater and rivers. Manages water crisis and avoids flood and droughts. Better management of the underground water table avoiding future water crisis
- 4. WHAT ARE THE USES OF IT? Indoor Household Usage Can be used for drinking, cooking, bathing, laundry, etc. Filtration system, boiling or distilling can be used for making rainwater usable for daily consumption Replacing water from water mains with rainwater in these activities offers the biggest contribution to water savings as they use a large volume of water year round.
- 5. WHAT ARE THE USES OF IT? Outdoor Household Usage Can be used for gardening, composting, livestock usage, irrigation etc. Plants prefer rainwater to mains water due to it being naturally soft and chlorine- free. Rainwater catchment system with storage tank can be used for fire protection. Can be utilized for outdoor water ponds or other water features like fountains
- 6. SIGNIFICANCE IN THE PRESENT CONTEXT OF URBANIZATION Allows the city to use their existing water infrastructure investments more efficiently. The practice of rainwater harvesting can reduce water demand and thus allow municipalities to provide potable water service at a lower cost. The rainwater harvesting industry can become a leading employer in the green infrastructure movement.
- 7. SIGNIFICANCE IN THE PRESENT CONTEXT OF URBANIZATION Rainwater harvesting is an important and vital part of developing a sustainable water resource path for any community. As local water resources are stretched to provide for population growth and economic development, new water supply strategies and paradigms will be necessary to meet this demand.
- 8. METHODS OF WATER HARVESTING IN A SETTLEMENT AND IN AN INDIVIDUAL BUILDING UNIT There are two ways of harvesting rainwater, namely; surface runoff harvesting and rooftop rainwater harvesting.
- 9. SURFACE RUNOFF HARVESTING Surface runoff rainwater harvesting is a method of collecting rainwater flowing along the ground during the rains will be collected to a tank below the surface of the ground for irrigation and other purposes. The main objective of surface runoff rainwater harvesting method is to meet the ever increasing demand of water, to reduce water pollution, soil erosion and flooding of roads.
- 10. ROOFTOP RAINWATER HARVESTING It is a system of catching rainwater where it falls. In rooftop harvesting, the roof becomes the catchments, and the rainwater is collected from the roof of the house/building. It can either be stored in a tank or diverted to artificial recharge system. This method is less expensive and very effective and if implemented properly helps in augmenting the groundwater level of the area.
- 11. ROOFTOP RAINWATER HARVESTING The system mainly constitutes of following sub components: Catchments Transportation First flush Filter
