Each year, the Public Works Department collects over 2,400 tonnes of waste from 16 kilometres of underground stormwater tunnels, benefitting around 70,000 residents.
This essential yet often unseen work helps prevent flooding and ensures public safety, especially ahead of the winter season.
During a recent visit to the National Flood Relief Project in Mosta, Parliamentary Secretary for Public Works Omar Farrugia praised the ongoing underground maintenance efforts.
He emphasised the importance of keeping stormwater systems clean and functional, describing it as part of a broader vision for a more resilient and sustainable Malta.
Perit Mario Ellul, Director of the Coastal and Stormwater Unit (CSU), said the government plans to expand the existing network by an additional 4 kilometres, bringing the total to 20 kilometres of key flood infrastructure.
The current system, located up to 25 metres below street level, includes 142 culverts and 94 oil filters that improve water quality before it enters the tunnels.
Beyond tunnel upkeep, the CSU is also building 2.3 kilometres of new culverts and maintaining major watercourses.
Moreover, over 13,000 cubic metres of rainwater were collected from cleaned rural reservoirs this year, helping farmers with irrigation and contributing to national water sustainability efforts.
