Ahmedabad: Water Hyacinth Infestation Disrupts Sabarmati River Front Activities
On Monday, the civic body released water from the Sabarmati River to lower its level in anticipation of heavy rain. However, a blanket of water hyacinth covered much of its surface, forcing the suspension of the popular floating restaurant on Tuesday. This unexpected development has cast doubt on the effectiveness of the Ahmedabad Municipal Corporation’s (AMC) cleaning efforts.
The Sabarmati Riverfront Development Corporation Ltd (SRFDCL) spends Rs 48,000 daily to operate four skimmer machines. “The infestation of water hyacinth is largely due to heat, evaporation, and elevated levels of sewage and nutrients in the water. Together, these factors trigger the proliferation of hyacinth,” said a senior AMC official.
The extent of the problem is visible from Indira Bridge to Subhash Bridge, and between Vasna Barrage and Dadhichi Bridge in Vadaj, where large patches of the weed have covered the river’s surface.
“When the water level at Vasna Barrage exceeds 135 feet, it forces us to release water from the riverfront as surrounding areas may get waterlogged,” the AMC official added. “These factors force us to open the barrage gates during heavy rainfall, as was done on Monday when five gates were opened by 3 feet to maintain the water level at around 132 feet.”
“Water hyacinth has choked the river to such an extent that it will take us at least a month to clear it,” said another AMC official, pleading anonymity.
The Sabarmati’s plight is further complicated by the discharge of sewage into it, despite crores spent on purification efforts. Unauthorized drainage connections continue to contribute to the issue.
“We are studying alternative methods followed by other Indian cities to control this menace. At present, sewage being released into storm water lines that empty into the river is a major concern,” added the AMC official.
