“Sanitation is fundamental to an improved quality of life due to the protection against-pollution of water resources and the reduction in water and vector-borne diseases that it provides. Owing to the limited access of a high share of urban and rural population to sewerage systems in India, strengthening the ecosystem for non-networked sanitation becomes imperative.

Packaged sewage treatment systems (PSTP) can provide a turnkey solution to the need of advanced on-site sewage treatment and are suitable for installation at the level of individual households or as a decentralized community-level solution. This standard for packaged sewage treatment plant (PSTP) aims to ease the implementation of these products as India amplifies its efforts to meet sustainable sanitation solutions that align to achieve sustainable goal of clean water and sanitation for all.

This Indian Standard outlines specifications which are critical for improving sanitation where traditional sewerage systems are inaccessible aiming to protect public health and environment. The PSTP units are designed to serve a population equivalent to minimum 5 people for complete treatment of sewage on-site and are suitable for underground installation at standard temperature and pressure conditions”
