Decentralized, state-of-the-art package plants that treat sewage where it’s generated — compact, low-power and simple to operate.
Domestic wastewater management for any city consists of collection, treatment and disposal. In conventional centralized sewage treatment systems, about 86% of the cost is accounted for by collection. The cost of collecting sewage and conveying it to the terminal point in large cities is very high — and the depth of the sewer keeps increasing with the length of the sewer line, while pumping the sewage at intermediate and terminal points requires a lot of energy. In a centralized system the volume of sewage becomes very large and the distance of conveyance is long, since sewage treatment plants are generally located outside the cities. Centralized treatment also aggravates environmental problems, because the large volume of wastewater from the entire city is discharged at one place. In a decentralized treatment system, a balance between the economies of scale of large treatment plants and individual responsibility for domestic wastewater can be achieved by providing colony-wise / sector-wise treatment. Responsibility for construction, operation and maintenance can be taken up collectively by residential colonies, builders and developers, and the specific treatment technology should be selected according to the prevailing ground situation, such as availability of land.
CWG offers decentralized, state-of-the-art package sewage treatment systems, engineered to the site.
Underground Sewage Treatment Plant based on a conventional bioreactor.
Mobile containerized STP based on a submerged-media aerobic reactor.
Compact plant based on a Fluidized Aerobic Reactor for tight footprints.
After biological treatment, water can be recovered through tertiary treatment and reused for gardening, flushing and other utilities. The compact package plant is simple to operate, needs minimal maintenance, and requires minimum power, land and consumables — reducing operating cost. Units are generally manufactured in MS epoxy-coated, stainless steel or FRP as per the specific need. These compact plants are ideal for hotels, hospitals, holiday resorts, country / golf clubs, schools, housing complexes, national parks and industrial & commercial complexes. Smaller decentralized local units are advantageous for treating communal wastewater / sewage, especially in areas where developing urbanization must integrate with the environment.
Responsibility for construction, operation and maintenance can be taken up collectively by residential colonies, builders and developers, with the treatment technology chosen to suit the site. CWG’s package systems — underground STP, mobile containerized STP (TBR) and compact FAR plants — recover water through tertiary treatment for reuse in gardening, flushing and other utilities, while keeping power, land and consumable requirements low.
Share your flow rate and effluent characteristics and CWG will size the right package sewage treatment plant for your site.
