Answer:
wastewater treatment
Explanation:
Wastewater (or waste water) is any water that has been affected by human use. Wastewater is "used water from any combination of domestic, industrial, commercial or agricultural activities, surface runoff or stormwater, and any sewer inflow or sewer infiltration".[1] Therefore, wastewater is a byproduct of domestic, industrial, commercial or agricultural activities. The characteristics of wastewater vary depending on the source. Types of wastewater include: domestic wastewater from households, municipal wastewater from communities (also called sewage) and industrial wastewater. Wastewater can contain physical, chemical and biological pollutants.
Households may produce wastewater from flush toilets, sinks, dishwashers, washing machines, bath tubs, and showers. Households that use dry toilets produce less wastewater than those that use flush toilets.
Wastewater may be conveyed in a sanitary sewer that conveys only sewage. Alternatively, wastewater can be transported in a combined sewer that conveys both stormwater runoff and sewage, and possibly also industrial wastewater. After treatment at a wastewater treatment plant, treated wastewater (also called effluent) is discharged to a receiving water body. The terms "wastewater reuse" and "water reclamation" apply if the treated waste is used for another purpose. Wastewater that is discharged to the environment without suitable treatment can cause water pollution.
In developing countries and in rural areas with low population densities, wastewater is often treated by various on-site sanitation systems and not conveyed in sewers. These systems include septic tanks connected to drain fields, on-site sewage systems (OSS), vermifilter systems and many more.
Explanation:
In India, tons of trash are left uncollected each year and end up in dumps that pollute the environment around the villages. The accumulation of this trash means production of lots of methane gas, which causes a greenhouse effect 21 times stronger than ‘CO2’.
However, the trash represents a source of revenue for many Indians, who collect it for resale at $1.50 per day. They recover recyclable materials such as plastic, paper, and glass, but the working conditions are horrifying and unsanitary. The health consequences for trash collectors are catastrophic, often cutting their life expectancy in half.
A solution to this environmental pollution does exist, allowing for cleaner and safer working conditions. This solution has already been tried and is being implemented in the south-east of India, in villages that are supported by Humanium. Each month, the villages are cleaned and the trash gathered, sorted and recycled. The trash is then separated into ‘Organic’ trash, which is composted and then used as natural fertilizer, and the ‘Reusable’ waste which is recycled.
Working conditions are much better and have decidedly improved the life expectancy of the villagers. Finally, environmentally speaking, the villages now enjoy a much cleaner space and, greenhouse gas emissions have been reduced.

Establishment of Solid Waste Management Systems
> Door-to-door collection, weighing and segregation of waste
> Dumping of biodegradable waste into compost, and non-biodegradable, non-recyclable waste into
landfill site.
> Sale of recyclable waste to scrap merchants
Eco-Friendly Sewerage System:
Through the system, the dirty sewage water of a village or town is collected in
one or more ponds. The collected municipal water, which is polluted but not toxic is treated by
simple methods of screening, filtration, sedimentation, rotation, etc. and made environmentally
acceptable and reusable for different purposes.

Some other measures are:
Ban on usage of plastic carry bags throughout the state.
Throwing garbage into streams has been made punishable.
Ban on use of disposables in departmental meetings and during religious functions.
Promoting school sanitation and hygiene education.
Installation of vending machines and disposers for sanitary napkins launched in 2011.
GREENATHON: cleaning up garbage as the participants walk along a street. The CLEANATHON,
Which is the regular cleanliness drive of offices, schools, and public places, is changing the face of
dirty areas.
A monthly cleanliness drive is observed in offices on every second Saturday of a month.
Generating money from activities surrounding waste such as selfie with garbage.
