Maintenance Instructions

The patented inspection / maintenance tunnels within each Stormbloc^® allows almost the entire volume of the construct to be inspected via a camera and flushed through.

A catchpit chamber immediately upstream of the system is recommended, as this will reduce the amount of siltation entering the installation. For larger installations it may also be advantageous to add further catchpits to the system design. The collection sump(s) should not be allowed to overfill as this will lead to silt carry-over into the Stormbloc^® modules. As all schemes are different the frequency at which the catchpit(s) should be emptied will need to be determined on site.

For small soakaways and individual infiltration tanks, it will generally only be necessary to ensure that the catchpits / silt traps are free from debris such as leaves and sediment.

It is recommended that any system be inspected no less frequently than at monthly intervals for the first 3 months and thereafter at 6 monthly intervals. In addition, it is suggested that the installation should be inspected immediately following the first infiltration event, whenever this should occur post installation. As all schemes are different individual maintenance schedules should be drawn up using the information obtained from the initial inspections.

It should also be noted that more regular inspections may be required should the catchpit(s) fill more frequently, and / or if initial inspections reveal that maintenance / cleaning will be required more regularly than at six month intervals.
