FILTRATION DETAILS

GENERALALL FILTER MATERIAL SHALL BE TESTED AND A CERTIFICATE PROVIDED FOR CONDUCTIVITY AND STRUCTURE BY A GEOTECHNICAL ENGINEER.

FILTER LAYERTHE FILTER MEDIA SHOULD BE BASED ON NATURAL OR AMENDED NATURAL SOILS OR IT CAN BE ENTIRELY ENGINEERED; IN EITHER CASE, IT CAN BE OF SILICEOUS OR CALCAREOUS ORIGIN. THE MEDIA SHALL HAVE HIGH PERMEABILITY UNDER COMPACTION AND SHALL BE FREE OF RUBBISH, DELETERIOUS MATERIAL, TOXICANTS, DECLARED PLANTS, WEEDS AND SHOULD NOT BE HYDROPHOBIC. THE FILTER MEDIA SHOULD CONTAIN SOME ORGANIC MATTER FOR INCREASED WATER HOLDING CAPACITY BUT BE LOW IN NUTRIENT CONTENT.IN THE CASE OF NATURAL OR AMENDED NATURAL SOILS, THE MEDIA SHOULD BE LOAMY SAND.

THE HYDRAULIC CONDUCTIVITY OF POTENTIAL FILTER MEDIA SHOULD BE MEASURED USING THE ASTM F1815-06 METHOD FOR A TROPICAL ZONE WITH FILTRATION RATE RANGING BETWEEN 100 TO 300mm/hr.

PARTICLE SIZE DISTRIBUTION (PSD) IS OF SECONDARY IMPORTANCE COMPARED WITH HYDRAULIC CONDUCTIVITY. THE FOLLOWING COMPOSITION RANGE (PERCENTAGE W/W) PROVIDES A GUIDE FOR SELECTING AN APPROPRIATE MATERIAL:-

● CLAY SILT <3% (<0.05mm)● VERY FINE 5-30% (0.05 - 0.15mm)● FINE SAND 10-30% (0.15 - 0.25mm)● MEDIUM TO COARSE SAND 40-60% (0.25 - 1.00mm)● COARSE SAND 7-10% (1.00 - 2.00mm)

THE FILTER MEDIA SHOULD BE WELL-GRADED WITH ALL PARTICLE SIZE RANGES PRESENT FROM THE 0.075mm TO THE 4.75mm SIEVE (AS DEFINED BY AS1289.3.6.1 - 1995). THERE SHOULD BE NO GAP IN THE PARTICLE SIZE GRADING, AND THE COMPOSITION SHOULD NOT BE DOMINATED BY A SMALL PARTICLE SIZE RANGE. THIS IS IMPORTANT FOR PREVENTING STRUCTURAL COLLAPSE DUE TO PARTICLE MIGRATION.FILTER MEDIA MUST BE TESTED AND MEET THE FOLLOWING CRITERIA:-

● TOTAL NITROGEN (TN) CONTENT - <1000mg/kg● ORTHOPHOSPHATE (PO ) CONTENT- <80mg/kg● ORGANIC MATTER CONTENT - 3% (w/w)● pH - 5.5-7.5 (pH 1:5 IN WATER)● ELECTRICAL CONDUCTIVITY (EC) <1.2dS/m

FOR INSTALLATION THE FILTER MEDIA SHALL BE LAID IN 250mm LAYER AND BE LIGHTLY COMPACTED DURING INSTALLATION TO PREVENT MIGRATION OF FINE PARTICLES. A SINGLE PASS WITH A VIBRATING PLACE SHOULD BE USED TO COMPACT THE FILTER MEDIA. UNDER NO CIRCUMSTANCE SHALL THE MEDIA BE HEAVILY COMPACTED OR MULTIPLE-PASSES BE MADE.

TOP TRANSITION LAYERTHE TOP 100mm TRANSITION LAYER SHALL CONSIST OF FILTER MEDIA USED IN THE FILTER LAYER AMELIORATED WITH THE FOLLOWING ORGANIC MATTER, FERTILIZER AND TRACE ELEMENTS AS FOLLOWS:-

CONSTITUENT QUANTITY (kg/100m² FILTER AREA)

GRANULATED POULTRY MANURE FINES 50SUPERPHOSPHATE 2MAGNESIUM SULPHATE 3POTASSIUM SULPHATE 2TRACE ELEMENT MIX 1FERTILIZER NPK (16.4.14) 4

TRANSITION LAYERTHE TRANSITION LAYER PREVENTS FILTER MEDIA FROM WASHING INTO THE DRAINAGE LAYER. TRANSITION LAYER MATERIAL SHALL BE A CLEAN, WELL-GRADED SAND MATERIAL CONTAINING <2% FINES.TO AVOID MIGRATION OF THE FILTER MEDIA INTO THE TRANSITION LAYER, THE PARTICLE SIZE DISTRIBUTION OF THE SAND SHOULD BE ASSESSED TO ENSURE IT MEETS 'BRIDGING CRITERIA', THAT IS, THE SMALLEST 15% OF THE SAND PARTICLES BRIDGE WITH THE LARGEST 15% OF THE FILTER MEDIA PARTICLES.

D (TRANSITION LAYER) < 5 x D (FILTER MEDIA)

WHERE: D (TRANSITION LAYER) IS THE 15 PERCENTILE PARTICLE SIZE IN THE TRANSITION LAYER MATERIAL.(ie. 15% OF THE GRAVEL IS SMALLER THAN D mm), AND

D (FILTER MEDIA) IS THE 85 PERCENTILE PARTICLE SIZE IN THE FILTER MEDIA.

DRAINAGE LAYERTHE DRAINAGE LAYER COLLECTS TREATED WATER AT THE BOTTOM OF THE SYSTEM AND CONVEYS IT TO THE UNDER DRAIN PIPES. DRAINAGE LAYER MATERIAL IS TO BE CLEAN, FINE GRAVEL CONSISTING OF 2-5mm WASHED SCREENINGS. BRIDGING CRITERIA SHOULD BE APPLIED TO AVOID MIGRATION OF THE TRANSITION LAYER INTO THE DRAINAGE LAYER.

D (DRAINAGE LAYER) < 5 x D (TRANSITION LAYER)

WHERE: D (DRAINAGE LAYER) IS THE 15 PERCENTILE PARTICLE SIZE IN THE DRAINAGE LAYER MATERIAL.(ie. 15% OF THE GRAVEL IS SMALLER THAN D mm), AND

D (TRANSITION LAYER) IS THE 85 PERCENTILE PARTICLE SIZE IN THE TRANSITION LAYER MATERIAL.

UNDER DRAIN PIPESTHE PERFORATIONS IN THE UNDER DRAIN PIPES SHALL BE SMALL ENOUGH THAT THE DRAINAGE LAYER CANNOT FALL INTO THE PIPES. THE D (DRAINAGE LAYER) IS GREATER THAT THE PIPE PERFORATION DIAMETER.

GEO-TEXTILE FABRICSGEO-TEXTILE FABRICS ARE NOT RECOMMENDED FOR USE BETWEEN LAYERS IN THE BIO-FILTRATION SYSTEM DUE TO THE RISK OF CLOGGING. AN OPEN-WEAVE SHADE CLOTH SHALL BE PLACED BETWEEN THE TRANSITION LAYER AND THE DRAINAGE LAYER TO HELP REDUCE THE DOWNWARD MIGRATION OF SMALLER PARTICLES. THE BASE AND SIDES SHALL BE LINED WITH A GEO-TEXTILE FILTER FABRIC TO PREVENT CONTAMINATION OF THE FILTRATION SYSTEM.

465 Appeals about decisions relating to extensions for approvals

(1) For a development approval given for a development application, a person to whom a

notice is given under section 389, other than a notice for a decision under section 386(2), may appeal to the court against the decision in the notice.
