DRAINAGE NOTES: CONCRETE TO BE 20mm NOM AGGREGATE AND HAVE A MINIMUM COMPRESSIVE STRENGTH AT 28 DAYS OF 20MPa FOR INSITU BASE AND 40MPa FOR PRECAST UNITS.

2. STEP IRONS TO BE INSTALLED IN PITS WHERE THE DEPTH FROM COVER TO TOP OF BASE EXCEDS 600mm

J IN HIGH GROUND WATER AREAS THE BASE AND PIT MUST BE SEALED AND BENCHED

4 SUBGRADE TO BASE TO BE COMPACTED TO 95% M.M.D.D PRIOR TO PLACING OF BASE

5 BACKFILL SURROUNDING PIT TO BE TO 95% M.MO.D

6. ALL PITS TO HAVE A WEEP HOLE IN ACCORDANCE WITH TABLE B, UNLESS IN HIGH GROUND WATER AREAS, SEE NOTE l

7 ALL PITS TO BE TRAPPED WITH MINIMUM 300mm DEPTH BELOW PIPE INVERT_

8. KERBS OTHER THAN MOUNTABLE AS SHOWN TO BE SIMILARLY TREATED BY MAINTAINING WIDTH AROUND SWEEPS AND GRADING DOWN TO COVER TOP OF FRAME

9_ PIPES TO BE FINISHED FLUSH WITH INSIDE OF LINER AND MADE GOOD WITH MORT AR

10 FOR DOUBLE SIDE ENTRY PITS AT LOW POINTS USE OPPOSING LEFT ANO RIGHT HAND DEFLECTORS SO AS TO INTERCEPT FLOW FROM BOTH DIRECTIONS

11 FDR SINGLE SIDE ENTRY PITS AT LOW POINTS USE FLAT APRON IN LIEU OF DEFLECTION SLAB.

12 PIPE SETOUT LINE CORRESPONDS WITH SETOUT DIMENSIONS FROM ROAD RESERVE BOUNDARY AS SHOWN ON DRAINAGE LAYOUT DRAWINGS
