GEOTEXTILE INLET FILTER CONSTRUCTION NOTES

1. FABRICATE A SEDIMENT BARRIER FROM GEOTEXTILE.

2. FOLLOW DETAIL FOR SEDIMENT FENCE FOR GEOFABRIC
INSTALLATION. REDUCE PICKET SPACINGS TO 1m CENTRES.

3. DO NOT COVER THE INLET WITH GEOTEXTILE UNLESS THE
DESIGN IS ADEQUATE TO ALLOW FOR ALL WATERS TO
BYPASS IT.

CLEAN /DIRTY DIVERSION DRAINS

DIVERSION DRAIN CONSTRUCTION NOTES

1. REMOVE ANY ROCKS, CLODS, STICKS OR GRASS FROM THE SURFACE BEFORE LAYING PLASTIC.

2. ENSURE THAT TOPSOIL IS AT LEAST 75mm _ DEEP.

3. ENSURE PLASTIC WILL BE CONTINUOUSLY IN CONTACT WITH THE SOIL BY GRADING THE SURFACE
CAREFULLY FIRST.

4. LAY FABRIC IN "SHINGLE FASHION”, WITH THE END OF EACH UPSTREAM ROLL OVERLAPPING THOSE
DOWNSTREAM. ENSURE EACH ROLL IS ANCHORED PROPERLY AT ITS UPSLOPE END.

5. ENSURE FULL WIDTH OF FLOW CHANNEL IS COVERED BY THE PLASTIC.

CONSTRUCTION NOTES

1. FABRICATE A SLEEVE FROM GEOTEXTILE OR WIRE MESH
LONGER THAN THE LENGTH OF THE INLET PIT AND FILL
WITH 25mm TO SOmm GRAVEL.

2. FORM AN ELLIPTICAL CROSS—SECIRCUITION APPROX. 150mm
HIGH, 400mm WIDE.

3. PLACE THE FILTER AT OPENING LEAVING AT LEAST
100mm BETWEEN KERB INLET AND SLEEVE. MAINTAIN
OPENING WITH SPACER BLOCKS.

4. FORM A SEAL WITH KERB TO PREVENT SEDIMENT
BYPASS.

5. SANDBAGS FILLED WITH GRAVEL CAN SUBSTITUTE FOR
THE MESH OR GEOTEXTILE PROVIDED THEY ARE PLACED
SO THAT THEY FIRMLY ABUT EACH OTHER AND
SEDIMENT LADEN WATERS CANNOT PASS BETWEEN.

sSEDIMENT FENCE CONSTRUCTION NOTES
1. CONSTRUCTION SEDIMENT FENCES AS CLOSE AS

POSSIBLE TO BEING PARALLEL TO THE CONTOURS OF THE

SITE, BUT WITH SMALL RETURNS. THE CATCHMENT AREA
SHOULD BE SMALL ENOUGH TO LIMIT WATER FLOW IF
CONCENTRATED AT ONE POINT.

2. CUT A 150-—mm DEEP TRENCH ALONG THE UPSLOPE
LINE OF THE FENCE FOR THE BOTTOM OF THE FABRIC TO
BE ENTRENCHED.

3. DRIVE TIMBER STAKES INTO GROUND AT 2.5m

INTERVALS (MAX) AT THE DOWNSLOPE EDGE OF THE TREN

4. FIX SELF—SUPPORTING GEOTEXTILE TO THE UPSLOPE
SIDE OF THE POSTS ENSURING IT GOES TO THE BASE OF
THE TRENCH. FIX THE GEOTEXTILE WITH WIRE RECOMMEND
BY THE MANUFACTURER. THE USE OF SHADE CLOTH FOR
THIS PURPOSE IS NOT SATISFACTORY.

5. JOIN SECTIONS OF THE FABRIC AT A SUPPORT POST
WITH A 150mm OVERLAP.

6. BACKFILL THE TRENCH OVER THE BASE OF THE FABRI
AND COMPACT IT THOROUGHLY OVER THE GEOTEXTILE.
