Lintel entries are the main entry point for surface
litter into stormwater collection systems, as there
are no filtration systems currently available for Lintel
Permapave Lintel Filtration Grates filter 100% of gross
pollutants from stormwater runoff, as it passes into
the collection system. Gross Pollutants remain on the
pavement where proper disposal is easily managed.
Permapave Lintel filtration grates are an economical
and extremely effective filtration system. Upon installation,
outfall waterways are immediately cleaner and less contaminated.
Capture rates are adjustable to suit most flow volumes
up to 100 litres per second per square metre of grate
As with any filter, periodic cleaning to remove retained
contaminants is necessary. The Lintel grates are easily
cleaned in situ with the Permapave Cleaning machine
