Drainage Improvement Projects


PUB has an island-wide drainage improvement programme to continually upgrade our drainage infrastructure to cater for new developments, alleviate flood risk and rehabilitate aging infrastructure. These “pathway” improvements include widening and deepening our drains and canals, constructing diversion canals and catchment level detention systems.
