6.1

Collection surfaces

Maintenance begins at the start of the rain cycle. A very dirty collection surface may produce an increased
amount of dirt for the system which then requires a lot of effort to filter out later on. To extend the service
life of the filters, we would therefore recommend maintaining the collection surfaces to remove large
pieces of dirt (leaves, grit etc.).
6.2

Filter unit

All kinds of filter units, see chapter 5, require maintenance to ensure the infiltration/attenuation system
operates perfectly. Perfect operation is essential for avoiding damage to the infiltration/attenuation system
and maintaining performance.
The pollutant levels depend on seasonal factors. During these periods, we would therefore recommend
checking the filter units for overflows or full sludge and dirt buckets. Increased dirt levels will arise in the
event of
- snow melt
- build-up of grit
- high pollen levels
- heavy rainfall during storms
- autumn leaf drop
The details provided by the manufacturer on maintaining and servicing the filter units used should also be
followed.
6.3 Inspection & performance of system
Regularly checking the infiltration/attenuation system will ensure high performance and guarantee the
rapid distribution of surface & rainwater in the event of heavy rainfall of a high intensity.
