Sewage Treatment Plant (STP) Guide Book

Filed under: Environment,Policy — san @ 9:27 am

In our experience with Apartment Complexes, we have found the STP to be that one piece of engineering that holds the most sustainability promise, and is a consistent pain-point for Management Committees.  In this regard, “The STP Guide”, a book written by Dr. Ananth Kodavasal, and published by the State Pollution Control Board, may come as a great knowledge aid. If you want to jump into the book right away, here it is: http://kspcb.gov.in/STP-Guide-web(Med).pdf

What is this Guide about

Introduction by Author:  Over five years ago, the Karnataka State Pollution Control Board mandated that Sewage Treatment Plants be built and operated in individual residential complexes having fifty or more dwellings, or generating 50 m3/day or more of sewage. Additional conditions imposed among others were that the treated water quality shall meet stringent “Urban Reuse Standards”, treated water shall be reused for
toilets flushing (thus requiring dual plumbing system in the residential complexes), for car washing, and for irrigation use within the campus.

A large residential complex, in its sewage generation potential, may then be viewed as a microcosm of the city itself; with a ready and perennial source of water right at its doorstep. All that the complex needs is to have a good, robust, well designed STP to produce water for all its secondary needs.

So, given this already grim and rapidly worsening [water supply] scenario, it is important for the people living in Bangalore and other mega cities in India to realize the importance of recycled water, and strive to set up efficient water treatment plants within their complexes, so that they can themselves control the quality of the water they use. At the same time, they will also be bringing down their own cost of living substantially, by obviating the laying of huge pipelines that bring water from far-off places.
This book will help them achieve this all important goal.

What does the Guide have

For each unit of the STP, the following aspects are addressed:

  1. The basic intended function of each unit
  2. How a typical unit looks like, and how it works
  3. Design considerations
  4. Engineering considerations
  5. Operation and maintenance aspects
  6. Troubleshooting chart

Who is it for

“For large and small builders alike, who generally depend on plumbing consultants for STP designs, this book serves as a reference. They can avoid a lot of costly rework and delayed projects by following the design and engineering recommendations made in this book.”

“The Managing Committees (and Estate Managers) of an apartment complex, this book provides both guidelines and checklists for taking over from the builders. It also provides detailed guidance for day-to-day operation and maintenance of STP. ”

We congratulate Dr.Ananth, also a user of ApartmentADDA, for this easy-to-read yet knowledge packed creation!
