A range of treatment is required to remove hazardous contaminants in wastewater before discharge. The article explains the measurements of the main parameters required in order to operate plants efficiently.

THE Corporation of Tiruchy is planning to set up a modern sewage treatment plant as part of the underground drainage (UGD) project within the city. The Tiruchy-Srirangam UGD project, along with the earlier one which is already functioning, is nearing completion. A third phase is also being drafted to accommodate the areas not covered under the earlier two phases. Meanwhile, the first phase is getting a new treatment plant in Panjappur with three pools and the cleaning process is under implementation.

The work on the 100-million-litre-a-day (MLD) seawater desalination plant at Minjur, on the northern outskirts of Chennai, is progressing expeditiously, Local Administration Minister M. K. Stalin informed the Assembly on Tuesday. Initiating the debate on the demand for grants to his department, he said the work would be completed this year. ILF-Mantech, an independent consultant, was appointed to monitor the work.

In this modern world of advanced techniques, sewage treatment works are considered to be one of the most popular procedures carried out to use the treated wastewater for agricultural purposes or to dispose off on to the land. The primary objective of this study is to design a Sewage Treatment System for Sri Satya Sai Urban Development Authority (SUDA) in Andhra Pradesh and studying the possibilities for usage of treated wastewater for irrigation. The study area, Puttaparthy being a pilgrim center attracts people all over the world and during some special occasions the place gets over crowded.

In the present study, an attempt has been made to evaluate the treatability of a combined tannery and domestic wastewater using lab-scale activated sludge reactor under extended aeration.

Human activities have significantly intensified natural phosphorus cycles, which has resulted in some serious environmental problems that modern societies face today. This article attempts to quantify the global phosphorus flows associated with present day mining, farming, animal feeding, and household consumption. Various physical characteristics of the related phosphorus fluxes as well as their environmental impacts
in different economies, including the United States, European
countries, and China, are examined.

In this paper, the economic impact of having a wastewater treatment plant (WWTP) for medium sized towns (Sivas and Fethiye) in Turkey with the objective of environmental pollution prevention is assessed by taking investment and operation costs, required tariff levels, affordability and willingness to pay of the users into account.

Sas Nagar: The Greater Mohali Area Development Authority (GMADA) recently tested its sewage treatment plant. But there is neither an approach road to the plant, nor any arrangement to transport the sewage water to the main treatment plant. According to sources in GMADA, the work for the approach road has not started yet because of a legal tussle between Authority and farmers, who own the land over which the road will be constructed. The pipes, which will bring sewage water to the treatment plant, could not be laid as a railway crossing falls in the way and the pipes would have to be laid beneath the rail tracks, for which the GMADA has not yet received the permission. However, according to a GMADA official, the Punjab and Haryana High Court has issued directions to Railway authorities to fix the pipes beneath the track soon. While the treatment plant is yet to start functioning, sewage water, stink and filth have become breeding grounds of mosquitoes, posing serious health problems for Mohali residents. Jaspal Singh, a resident of Phase-IX, said that due to the foul smell emanating from the nullah passing through the phase, residents have been suffering for the past many years. Singh said the nullah was a seasonal drain but with the passage of time, the garbage and sewage water from Chandigarh and Mohali started flowing into it and now it has become impossible to livge near it. "I want to sell my house but there are no buyers and in case some people turn up, they offer very cheap price as compared to houses in other sectors or phases in Mohali,' he said. Singh said that there were hundreds of other residents in the area, whose health has been ruined due to the poor health condition around the nullah. "The authorities in the past have submitted many affidavits in the High Court promising to start the sewage treatment plant on a stipulated date, but before the date arrives, they seek further extension,' he added. When contacted on the issue, GMADA Chief Administrator Vijay Pratap Singh said the GMADA is already working on both the issues. "Chandigarh MC and GMADA have taken up a joint survey to plug the points from where the sewage is being thrown into the drain. Gradually, we will also be able to solve the problem of the stink emanating from the nullah' he added
