The Council of Scientific and Industrial Research Research Institute for Environmental Engineering (CSIR-Neeri) has completed three rounds of monitoring on EDAppalls and Thevara-Prandoor Canals as part of the feasibility study on the development of the process package for domestic waste substances discharged into watercourses.
The project also includes channels Pattolite and Valiyat in Kollam, which is performed under the supervision of the Council Council. The National Green Tribunal (NGT) previously ordered the government to take steps to check the indiscriminate degradation of channels caused by illegal release of untreated waste water into them.
In his second progress report in the feasibility study of 25 February 2025 and the presented to the Council, the Scientific Agency reported that it has completed the discharge of the discharge of untreated wastewater into the channels. According to official data, it was found that a total of 12 drainage leads to Edappally and Thevara-Perrandoor channel.
The physically -chemic properties of water samples taken from four channels during two rounds of monitoring (April and October 2024) were low in organic substances, inorganists and nutrients, which classified water as a low strength. The presence of heavy metals was either under detectable limits or was found in extremely low concentrations.
CSIR-Neeri investigators asked the Council to submit details of the departments in the studied area of Edappall and Thevara-Perrandoor channels to predict the population and determine the hydraulic load for the proposed wastewater treatment plants (STP).
To prepare the final report, they applied for secondary data, including measurement of water flow from the irrigation department at various locations along four channels and details of land available under the government bodies for the construction of STP to make waste water from identified channels and drains. The team was also looking for details of identified channels and unlaps, including their depth, width, length and flow of waste water.
The future identified course of work includes recommendations and proposals to improve water quality in four channels and a strategy for project implementation.
