Small sewage treatment plants, also known as package or plug-and-play sewage treatment plants, are designed to treat sewage generated by individual households or a cluster of homes. In countries where construction costs are high, these prefabricated sewage treatment plants are sold because they have a short installation time.

In India, transportation and logistics costs are significantly higher compared to the cost of construction at the site. To address this issue, EcoTec recommends constructing tanks on-site, tailored to the site's specific conditions, with a flexible approach to the size and method of construction. Once constructed, the treatment technology is supplied as a retrofit kit, and installed into the tanks within a day. This approach not only saves money for the customer but also allows for EcoTec EcoSBRcompact sewage treatment plants have been treating wastewater for reuse for gardens in many homes throughout India.

New homes that can be built with separate plumbing for flushes can be given with filtration and disinfection units.
