1.1 Introduction
This report will cover the history, operations and future potential for the St Marys Sewage Treatment Plant and St Mary’s Water Recycling Plant, which located in an industrial area in St Mary’s, a western suburb of Sydney.

A group of subject 48350 Environmental and Sanitation Engineering students visited both plants, and observed the operations and maintenance of these wastewater treatment systems.

In 1939, the Sewage Treatment Plant was first commissioned at St Mary where it serviced a government facility nearby using a trickling filter system – obviously a small scale operation.

The Plant was

St Marys Sewage Treatment and Recycled Water Plants are not planned for explanation in next few years. However, there is a plan in general that are to construct more sewage treatment plants and implement more recycled water processing plants around Sydney where the population is predicted to increase significantly in next 5 years period (from 4 to 6 million).

More urgently however, is the need for infrastructure rejuvenation, prompting the SewerFix program, which has been operating since 2008 to repair leaks, clear blockages and refurbish old sewage piping and pumping infrastructure to improve overall system efficiency and minimise the possibility of spills. An estimated $560 million will be invested into the project over the course of 4 years from 2008 to 2012.

Moreover, at this time, it is importance to rejuvenate infrastructure and prompt the SewerFix program. Since 2008, those has been operating to repair leaks, clear blockages and refurbish old sewage piping and pumping infrastructure to improve overall system efficiency and minimise the possibility of spills. An estimated $400 million will be invested into the project over the course of 4 years from 2012 to 2016 (sewerFix Program, 2012).
