Maintenance Procedures
Stormwater pollutants captured and retained by the
SPELFilter system need to be periodically removed to
ensure environmental values are upheld. All associated
maintenance works is heavily dependent on the
site’s operational activities and generated stormwater
pollutants. To ensure the longevity of the installed
SPELFilter treatment system, it is imperative that the
procedures detailed in this Guide are followed and all
appropriate measures are actioned immediately.
Standard inspection
The standard inspection requires personal experience
of SPEL products to visual inspection the vault and
filter conditions.
Confined space requirements may not be required if a
full inspection and assessment of each SPELFilter can
be achieved at surface level without being deemed a
confined space entry.

Site Inspection Procedures
1. Implement Pre-start safety measures.
Ensure that the area in which operational works are to
be carried out is cordoned off, to prevent unauthorised
access. Adequate safety barriers must be erected.
Area in which work is to be carried out must be clean,
safe and hazard free. (Refer to figure 4.)
2. Set-up Gantry Tri-pod above Manhole.
Assemble and position the gantry above the manhole
safely and as practically as possible. Attach the winch
or chain block to the gantry for lifting the SPEL Filters.
Perform safety procedures ie. Attach harnesses etc. (if
confined space).
3. Open manhole lid.
Once you have sent up the Gantry and ensured that
the area is safe to operate in, you can proceed to open
the manhole lid, using lid lifters.
4. Conduct Gas tests.
(If tank is classed confined space)
Once the lids have been removed to a safe distance
to prevent tripping, you must then proceed to conduct
gas tests. Perform necessary gas tests according to
the confined space regulations.
5. Once confined space has been deemed safe to
operate in, enter tank safely.
Once you have carried out the required gas test and
the work area is deemed safe, you may then enter the
pit via a ladder or winch system to assess the work
area you will be operating in. Ensure all confined space
6. SPELFilter system assessment.
Perform a review of the SPELFilter system using the
SPELFilter assessment report/checklist. Sign off and
forward a copy of the report to property manager and
SPEL representative.
7. Reinstate SPELFilter system and disposal.
At the completion of the site inspection, ensure the site
is reinstated back to its initial state and all pollutants
are removed from the site in line with pollutant
disposal procedures.
8. Sign off and forward a copy of the report to
property manager and SPEL representative.
