Sustainable Drainage Systems
Stormwater Drainage
Health & Safety Benefits
There is a misconception that standing water in permeable pavements may be a health hazard. This is not the case as these pavements drain down fairly quickly after rainfall occurs and therefore there will be no significant volume of water within these pavements for most of the time. As they are very shallow structures the issue of accessibility does not arise and indeed these are very safe structure when compared with alternative storm drainage solutions.
Oil Separation
When using permeable pavements, separate oil separation techniques are not required, and indeed research has shown that these systems are more effective at removing a wide range of pollutants that oil interceptors are. If additional treatment is required, then the treatment train approach should be used.
Frost Action
A further misconception is that freezing of the water stored within the sub-base may cause damage to the pavement structure. In fact these pavements will drain down before any freezing can occur, and monitoring of projects done in much more extreme climates than our own has shown that non have failed due to frost heave. In fact, it was found that frost penetration was shallower within permeable pavements than in conventional pavements.
