Sri Lanka's cabinet has given the green light to a Rs15 billion allocation designed to breathe new life into the Kolonnawa drainage project, a key infrastructure initiative that has faced extended delays and setbacks in recent years.

The Kolonnawa drainage scheme, which serves the greater Colombo area, has been identified as critical to managing waterlogging and flooding issues that periodically affect residents and businesses in the region. The renewed funding commitment represents a significant step toward addressing these persistent urban infrastructure challenges.

Official sources indicate the financial package will be utilized to resume and accelerate work on the project, which had encountered implementation difficulties over the past period. The revival initiative reflects government prioritization of drainage and flood management systems as part of broader urban infrastructure development efforts.

The project's completion is expected to enhance the capital's resilience to seasonal weather patterns and improve overall urban management. Additional technical and administrative details regarding implementation timelines and project scope are anticipated to be announced through relevant authorities.
