D - Diversion (Referring to the diversion of waste from landfills through recycling and composting) H - Hydration (Highlighting the importance of water for irrigation and proper hydration of plants) A - Adaptation (Signifying the need to adapt waste management and irrigation practices to changing environmental conditions) R - Reuse (Emphasizing the reuse of materials and water in waste management and irrigation systems) A - Allocation (Referring to the strategic allocation of resources in waste management and irrigation for optimal efficiency)
The word " Dhara " is derived from the Sanskrit root " dhri ," meaning "to hold" or "to sustain and is also considered as consort of Lord Vishnu .It signifies the Earth's ability to sustain life and provide the necessary resources for the well-being of all living beings. Dhara is often depicted as a goddess, symbolizing the bountiful and nurturing nature of the Earth.
Dhara consists of three main aspects Using greywater from the buildings to use it for irrigation Managing the waste properly Using the efficient energy sources for street lights
Using greywater from the buildings to use it for irrigation Greywater refers to the wastewater generated from various domestic sources in a household, excluding water from washrooms (which is known as blackwater ). It typically includes water from bathroom sinks, showers, bathtubs, and washing machines. Dhara uses the greywater in its sprinkle irrigation after properly filtering it to supply it to plants
Sprinkle irrigation systems are designed to deliver water directly to the targeted areas, reducing water wastage compared to other irrigation methods,conserving water resources which for efficient water distribution, ensuring that plants receive the necessary moisture while avoiding overwatering.
Managing the waste properly . Dhara uses smart dustbins with sensors that provide a signal when they are full are a convenient and innovative solution for waste management. It optimize waste collection routes by sending signals when they reach their capacity. This feature allows waste management teams to focus their efforts on bins that require immediate attention, streamlining the waste collection process.
While traditional bins that overflow can create unhygienic conditions and attract pests. Smart dustbins that provide signals when they are full enable prompt emptying, ensuring cleaner surroundings and minimizing the risk of contamination and the spread of diseases. It also reduce unnecessary collection trips. This can lead to cost savings in terms of fuel consumption, labor hours, and overall operational expenses for waste management authorities.
Using the efficient energy sources for street lights By using solar energy for street lighting, we reduce dependence on fossil fuels and contribute to a greener and more sustainable future. Solar-powered street lighting eliminates the need for extensive electrical infrastructure and grid connections. Once installed, solar panels generate electricity for the street lights without ongoing utility costs, resulting in significant long-term savings.
Solar-powered street lights operate independently of the electrical grid. This independence provides greater resilience to power outages, ensuring continuous lighting even during emergencies or grid failures. Solar-powered street lighting has a minimal environmental footprint. It helps reduce carbon emissions and air pollution by eliminating the need for electricity generated from fossil fuels. Additionally, it avoids light pollution by utilizing efficient LED lighting technology and appropriate light distribution.
