Factors that influence the maintenance requirements of pervious surfaces and impact on the design criteria include:
Maintenance includes vacuum-cleaning using commercially available sweeping
machines and ensuring site owners are given a clear checklist of the monitoring
and maintenance requirements. The effects of maintenance (or lack of it) on
infiltration rates
is discussed together with the likely frequency of sweeping.
Materials removed from the voids or the layers below the surface may contain
heavy metals and hydrocarbons (as is the case with asphalt surfacing) and
need to be disposed as a controlled waste. This is no more onerous than the
disposal of gulley pot or interceptor sediments. The applicable legislation
is discussed in detail.
Other methods of maintenance include lifting and relaying blocks where they
become completely blocked.
