Authorities have clarified that chemicals released by a private institution near the Kelani River intake point did not contaminate the drinking water supply, with preliminary tests indicating the substances are non-toxic.
The Disaster Management Centre (DMC) has issued a statement regarding an incident involving chemical discharge into the environment near a critical water supply intake point. According to DMC Director Pradeep Kodippili, the centre was notified of the situation on the evening of the 24th and responded immediately with preventive measures to safeguard the drinking water system.
As a precautionary measure, the National Water Supply and Drainage Board (NWSDB) temporarily halted water distribution to several areas across Colombo and Gampaha districts due to concerns about water quality near the Kelani River intake. The suspension was implemented while authorities investigated the extent of the chemical release and its potential impact on the water supply network.
Following containment efforts involving assistance from the tri-forces, the situation was brought under control. Laboratory testing was subsequently conducted to verify water quality standards, and results from these tests informed the decision to restore supply. The DMC Director noted that while testing remains ongoing, preliminary findings have indicated that the chemicals involved are non-toxic in nature. Based on DMC recommendations and confirmed laboratory results showing water met required quality standards, normal water supply operations were resumed to affected areas.
