Water is important for life. Due to urbanization and industrialization water gets contaminated by harmful microorganisms (pathogens), suspended and dissolved impurities etc. People suffer from water borne diseases like Cholera, typhoid, jaundice, if they consume contaminated or impure water, which is sometimes fatal. The process of washing, cooking also gets affected if the water is hard. It is therefore necessary that water we use daily should be of good quality for drinking and other use as stipulated by IS 10500. Hence water treatment plants are required to treat water for cities, towns, villages, residential complexes, hotels, swimming tanks, schools & colleges, resorts etc. Certain industries also require water of very good quality in manufacturing process. It is also necessary to check the quality of water regularly from authorized water testing laboratories.

Domestic waste water or sewage if disposed without treatment, results in pollution of water bodies, ground water etc. As per Water Act, sewage has to be treated to conform to effluent standards as stipulated by IS 2499. Traditionally sewage treatment was the responsibility of local self governments such as Municipal Corporations, Municipal bodies etc. But now a days it is made mandatory for big residential complexes to provide sewage treatment plants. Many residential complexes are providing STP voluntarily to reuse and recycle water for purposes such as flushing, car washing etc. The ever increasing rates of water makes it sensible to provide STP.

Rainwater harvesting is the accumulation and deposition of rainwater for reuse before it reaches the aquifer. Uses include water for garden, water for livestock, water for irrigation, and indoor heating for houses etc. In many places the water collected is just redirected to a deep pit with percolation. The harvested water can be used as drinking water as well as for storage and other purpose like irrigation.

The industrial effluent or wastewater is different from domestic wastewater. The characteristics of industrial effluents like BOD, COD, pH, Oil and Grease, Suspended and dissolved impurities vary widely. They may also contain toxic and hazardous substances, which need chemical treatment. As per Water Act, industry has to install ETP to treat the effluents before disposal. As the rate of water industries is very high compared to domestic rate many industries prefer to reuse and recycle the effluent after treatment.
