The maintenance procedure for a – – is fairly simple. A necessary requirement of the use of the Gross pollutant trap is the need for regular inspection, maintenance and cleaning. This regularity is defined by the catchment area that it is located in and the features and properties of the surroundings. Regardless of the catchment area features, it is recommended by PROTECTOR that there is a mandatory inspection after 1 month of use after installation to determine the amount of capture of gross pollutants and sediments and determination of regularity of maintenance can be taken from this.
As previously stated, any form of weather conditions outside the norm of which the specific is design fall, be it high rainfall or heavy storm conditions, an immediate inspection is recommended.
NB: when maintenance is conducted on the GROSS POLLUTANT TRAP system, ensure that all Workplace health and Safety precautions and directions are adhered to and the Confined space Regulations are carefully followed when required.
The cleaning and maintenance procedure is simple, requiring removal of the access cover and inserting a suction hose into the chamber, recommended use of a vacuum loader truck. Remove all forms of refuse and debris before entering the chamber. Always ensure cleaning is begun from the inlet side of the chamber and ensure carefully resecuring of the access cover when completed.
Specific maintenance procedures of each aspect of the stormwater treatment system is outlined below. All maintenance must be carried out by some authorised personnel and all OH and S regulations and confined space regulations must be strictly followed.
1. Remove access manway carefully and safely.
2. Using a vacuum or hose truck, insert a suction hose into the chamber. Remove all forms of refuse, silt and debris before entering the chamber. Always ensure cleaning is begun from the inlet side of the chamber and ensure carefully resecuring of the access cover when completed.
1. Gross Collector – Remove all sediment, gross pollutants and anything other trash that can restrict water flow.
2. Trash screen – ensure that all clogging is removed, and that water can flow without obstacle through the trash screen
3. Bypass channel – clean out all sediment that may have entered the bypass.
4. Dropper pipe and Riser Tube – ensure clogging has not occurred and that free flow is possible.
5. Silt Chamber – Use that vacuum truck and hose to remove all sedimentation at the bottom of the GROSS POLLUTANT TRAP
