Sewage flow turns Madurai’s waterbodies into drains

Once captious lifelines for people, respective waterbodies successful Madurai present prevarication successful a authorities of neglect. Rapid urbanisation and the summation of residential and commercialized establishments person taken a toll connected these accepted irrigation channels, which were erstwhile filled with cleanable water.

Today, galore are choked with sewage and emit a beardown foul odour. Experts constituent retired that inadequate underground drainage (UGD) sum and the constricted capableness of sewage attraction plants (STPs) are the main factors contributing to the deterioration of these channels.

One specified waterbody is the Panthalkudi channel, which originates from Sellur irrigation vessel and flows done Meenambalpuram, Narimedu, and respective areas successful and astir Sellur earlier draining into the Vaigai River.

Speaking connected the issue, a societal idiosyncratic and nonmigratory of Sellur N.P. Sankar Pandi said that stretching implicit astir 3 kilometres, the Panthalkudi transmission has remained successful a mediocre information for much than 15 years.

“We person already submitted a petition requesting desilting of the channel, but nary enactment has been taken truthful far,” helium said. He besides pointed retired that deficiency of nationalist consciousness astir the consequences of dumping discarded into the waterbody exacerbates the problem, particularly during the monsoon and dense rainfall period.

“As the irrigation vessel has efficaciously turned into a drainage channel, its h2o often seeps into the groundwater, causing residents to acquisition tegument diseases and different wellness issues,” Mr. Sankar Pandi said.

He further noted that the sewage attraction plant, with a capableness of 2 MLD (million litres per day), is insufficient to grip the inflow. “The Corporation, on with the Public Works Department, indispensable instrumentality steps to desilt the Panthalkudi transmission and conception retaining walls connected either broadside of the waterbody,” helium said.

When asked astir the crushed for sewage entering the channel, Mr. Sankar Pandi explained that galore areas successful Sellur deficiency underground drainage (UGD) connections, forcing residents to discharge untreated wastewater into the adjacent waterbody.

“Even successful houses with UGD systems, the capableness is often insufficient, prompting residents to link their drains to stormwater channels, which were primitively designed to transportation lone rainwater. The occupation is further aggravated during the monsoon, erstwhile overflowing drains transportation coagulated discarded and sludge into the waterbodies, compromising h2o prime and posing nationalist wellness risks for adjacent residents,” helium said. Mr. Sankar Pandi urged the Corporation to guarantee that UGD connections are installed successful each households successful Sellur and different affected areas.

Deplorable authorities of Kiruthumal river

Another important and past waterbody successful the city, akin to the Vaigai River, is the Kiruthumal River, which is present successful a deplorable authorities contempt its humanities and spiritual significance. The stream flows done respective parts of Madurai — portion the Vaigai marks the city’s bluish boundary, the Kiruthumal flows done its confederate and cardinal regions. It flows eastward from Tirumangalam, done the confederate parts of Madurai city, and yet merges with the Vaigai River adjacent Tirupparankundram. Once a captious root for irrigation and groundwater recharge, the stream has, implicit the decades, been reduced to a wastewater channel.

Secretary of the Madurai District Farmers’ Association Alagu Servai recalled that until the 1960s, the Kiruthumal River remained axenic and supported agriculture crossed the region. “Before the 1960s, h2o from the Anupanadi transmission drained into the Kiruthumal River and was extensively utilized for irrigation. But aft the 1960s, with the gradual emergence of commercialized and residential buildings successful areas specified arsenic Chinthamani and its surroundings, the stream began to deteriorate,” helium said.

He said each large channels successful Madurai, including Chinthamani and Samanatham, erstwhile drained into the Kiruthumal River and served the assemblage effectively. Over the years, however, indiscriminate dumping of household and concern discarded has reduced these lifelines to a deplorable condition. “The channels that drain into the Kiruthumal River adjacent Kochadai are highly polluted,” added Mr. Alagu Servai.

When asked astir the projected vertebrate sanctuary on the Samanatham channel, Mr. Alagu Servai said that this is simply a bully idea, but unless the mediocre information of the transmission is addressed, the program to make the sanctuary would beryllium rendered futile.

He emphasised that residents indispensable cultivate the wont of keeping their surroundings cleanable and refrain from dumping garbage into waterbodies. In summation to discarded disposal, helium pointed retired that the Corporation indispensable instrumentality enactment to code the discharge of municipality drainage into these tanks and channels, arsenic it is simply a large contributor to their pollution.

Advocate Mani Bharathi filed a petition astatine the opening of October, seeking the removal of encroachments and measures to forestall sewage from flowing into the river. He besides urged the tribunal to nonstop the authorities to transportation retired a integer survey utilizing the Differential Global Positioning System (DGPS) — a method earlier implemented for mapping the Cooum River successful Chennai. The petition is inactive pending earlier the court, which has sought interim clarifications from the authorities, including details connected the circumstantial points wherever sewage enters the stream and the funds allocated for its restoration.

He besides said that 2 months earlier filing the petition, the authorities had allocated funds that are present being utilised for constructing retaining walls on the Kiruthumal River astatine the Achampathu side. “We person requested that the authorities behaviour a due survey to measurement the river’s width earlier gathering retaining walls, to guarantee that the operation does not further constrictive the waterbody’s course,” helium added.

The Centre for Urban Water Resources (CURE) nether DHAN Foundation has been playing a cardinal relation successful the restoration of waterbodies successful mediocre information crossed Madurai. One of the officials said that efforts to marque the Vaigai River sewage-free indispensable statesman with restoring the web of channels and ponds that drain into it and preventing the discharge of untreated wastewater. “If the revival of the Vaigai becomes a governmental and administrative priority, the stream tin beryllium restored to its archetypal state,” the authoritative said.

Speaking to The Hindu connected the contented of underground drainage, Corporation Commissioner Chitra Vijayan said that astir of the waterbodies present carrying sewage are located adjacent habitations and encroached areas. She added that a task worthy ₹400 crore for expanding the UGD web is already nether implementation, and further proposals volition beryllium announced later.
