In India, there are a total of 1093 sewage treatment plants.
Many companies offer wastewater treatment systems. I would search on line to find companies in your area. Then, I would ask those companies to come out and provide you with a quotes. The EPA provides a manual on wastewater treatment systems at http://www.epa.gov/nrmrl/pubs/625r00008/html/625R00008.htm.

People who live in the city are not very concerned with their wastewater treatment method or system since their waste is routed through the city’s pipelines to its destination. People who live in rural areas are more concerned with their waste disposal and their wastewater treatment methods. Many times, people who lived in rural areas where septic tanks or sewers are not available for various reasons must look into other alternatives for wastewater treatment systems. Thanks to the advancement of technology, today there are many wastewater treatment choices available either to individual households or for commercial use, even for areas where water is not as abundant or readily available as in areas closer to the city. Some wastewater treatment units are similar to septic tanks in the sense that they are usually about the same size and installed almost the same way; however, they are different in the internal mechanisms and components that treat the waste. They are more like versions of municipal treatment plants in the way they work, with the difference that these miniatures are designed for a single-family use. The way the waste is disposed of after treatment is also different. Another alternative is compost toilets. These use minimal or no water and do not require to a sewer line or septic system. One important characteristic to look for when you select this system is that it is NSF certified and has the NSF mark on it, otherwise you are risking on buying a misleading product that will not function up to standards. The result will be improper treated waste and odors. Incinerating toilets are another alternative. The waste is burned on a holding tank and converted into ash, which can be disposed into the garbage. A propane or electric heating system incinerates the waste. It does not require water and is mostly odor free. All these methods save water and can be used in remote areas where water is scarce or there are no city lines. It is important to consult the city or public health building for any special permits and to find out about any regulations on installing these types of systems.
There are many job postings online, or in your local newspaper. If you have any water power plants around you, you can go in and ask them if they know, or have any jobs.

The weakness in industrial wastewater management was the main cause of water pollution in Vietnam. Many industrial facilities used freshwater to carry away waste from their plants into canals, rivers, and lakes. Most of the enterprises did not have any wastewater treatment system and many industrial zones did not have a central wastewater treatment plant. Industrial wastewater was directly discharged into canals, lakes, ponds, and rivers, causing serious pollution of surface water. For example, in 2008, Vedan factory, a sodium glutamate plant, released their untreated industrial wastewater into the Thi Vai River and caused tons of fish and ducks in the river to die. Besides, the growing number of factories along the river and their untreated waste disposal was causing a lot of diseases and intestinal sicknesses among people living in the vicinity of the river. The water pollution was clearly visible, and residents could see a tarred black color and smell a pungent odor from the river. Therefore, one Japanese cargo ship refused to dock at Go Dau port on Thi Vai River because the water could corrode the ship's hulls. In short, uncontrolled disposal of industrial wastewater was a huge source of water pollution, and it produced pollutants that were extremely harmful to people and the environment.
