Before installing your tank:

• Ensure you have Building Regulation approval
• Ensure you have conducted a percolation test and that ground porosity is suitable
• Inspect the tank for any damage prior to installation. Our tanks have been fully tested before dispatch from the factory, and once installed, Klargester cannot accept claims for damage
• Check that you have the correct invert drain depth (neck height) of the tank – a label indicates the maximum permissible depth
• Ensure a de-sludging tanker will be able to access the tank
• Check the orientation and heights of the inlets and outlets
• Check that the tank is suitable for its application – septic tanks and cesspools should not be used for silage effluent, chemical toilet waste or any other chemicals

Do:

• Use the correct backfill material
• Site the tank at the furthest practical location from habitable dwellings. Most building regulations recommend a minimum of 15m, whereas some require 25m.
• Fit the correct cover and frame for the tank, and ensure it is adequate for the site (standard cover for pedestrian duty, or heavy duty if large vehicles will be travelling over the site)
• Consider any ventilation arrangements
• Consider drainage falls, generally 1 in 60/70 between the house and tank, and maximum 1 in 200 for the irrigation system
• Lift the tank using ropes or slings through both of the shackles fitted either side of the neck

Do Not:

• Subject the tank to impact or contact with sharp edges
• Add neck extensions to the tank, or build a brick manhole above the tank neck (as this increases the burial depth of the tank). We do not recommend extending the neck of the tank under any circumstances
• Install the tank deeper than the depth that the fitted neck will allow
• Install in trafficked areas without a suitable backfill design
• Site the tank so that it is subjected to excess ground pressure or applied loads such as may be generated by the proximity of vehicular traffic
• Lift using only one of the shackles
• Fill an unsupported tank
