STORMWATER DRAINAGE PLANSCALE 1:200

SITE DATA:

SITE CLASSIFICATION = TO BE CONFIRMEDGROUND WATER TABLE = OVER 2.5m BELOW EXISTING GROUND LEVELSOIL PERMEABILITY = 2 m/day (TO BE CONFIRMED)

GENERAL NOTES:1. DATUM IS LOCAL AND TO BE VERIFIED ON SITE.2. CHECK ALL DIMENSIONS ON SITE. READ ALL ENGINEERING DRAWINGS IN

CONJUNCTION WITH ARCHITECTURAL & SURVEY DRAWINGS. ANY DISCREPANCIESBETWEEN ENGINEERING DRAWINGS AND ARCHITECTURAL DRAWINGS SHALL BECONFIRMED PRIOR TO COMMENCING CONSTRUCTION. DO NOT SCALE FROM THESEDRAWINGS.

3. ALL WORK TO BE IN ACCORDANCE WITH "AS3500-2003 PLUMBING & DRAINAGE", THE"BUILDING CODE OF AUSTRALIA" AND THE LOCAL AUTHORITY'S STANDARDSPECIFICATIONS.

4. LOT CONNECTION PIT (WHEN APPLICABLE) TO LOCAL AUTHORITY SPECIFICATIONS.5. WHERE MANHOLES ARE LOCATED IN THE AREAS SUBJECT TO VEHICULAR LOADING,

STANDARD TRAFFICABLE LIDS ARE TO BE INSTALLED & BASED TO BUILDER'S DETAIL.6. ALL DRAINAGE PIPEWORK SHALL BE PVC CLASS HD STORMWATER, UNLESS WHERE

LOCATED UNDERNEATH ANY STRUCTURES PIPEWORK SHALL BE PVC SEWER CLASS SN8.7. ALIGNMENT OF PIPES SHALL BE AS SHOWN ON THE PLAN & SHALL BE TO THE PIPE OR

MANHOLE CENTRELINE.8. BEFORE CONSTRUCTION COMMENCES, THE CONTRACTOR SHALL:

A. CHECK ON SITE THE LOCATION OF THE EXISTING SERVICES WITH THEAPPROPRIATE AUTHORITY. ENSURE PROPOSED STORMWATER PIPE DOES NOTCLASH WITH ANY EXISTING SERVICES.

B. ARRANGE FOR THE LOCATION AND THE LEVEL OF THE CONNECTION POINT TOEXISTING STORMWATER MANHOLE TO BE VERIFIED BY A SURVEYOR.

C. CONFIRM THAT BOUNDARY PEGS OR OTHER SURVEY REFERENCE POINTS TO BEUSED IN SETTING OUT OF THE PROJECT ARE LOCATED IN THE CORRECTPOSITIONS.

D. ENSURE A PERMIT & REINSTATEMENT SPECIFICATIONS ARE OBTAINED FROM THELOCAL AUTHORITY IF EXCAVATION WILL BE IN A ROAD RESERVE OR RIGHT OFWAY.

E. ENSURE ALL DETAILS HAVE BEEN CHECKED AND THAT NO DISCREPANCIES EXIST.ALL QUERIES AND DISCREPANCIES ARE TO BE RESOLVED PRIOR TOCOMMENCING WORKS.

11. ALL EXCAVATIONS SHALL BE SECURED & MADE SAFE IN ACCORDANCE WITHREQUIREMENTS OF THE OCCUPATIONAL SAFETY & HEALTH ACT OF 1984, THEOCCUPATIONAL SAFETY & HEALTH REGULATION 1996 & OF ANY RELEVANTREGULATORY BODY.

12. PROPERTIES WHICH HAVE BEEN EXCAVATED SHALL BE RETURNED TO AT LEAST ASIMILAR CONDITION TO THAT WHICH EXISTED PRIOR TO CONSTRUCTION.

13. TRENCH BACKFILL SHALL BE CLEAN GRANULAR MATERIAL, COMPACTED TO A LEVELNOT LESS THAN THAT OF THE SURROUNDING UNDISTURBED GROUND, FOR THE FULLDEPTH OF EXCAVATION. BACKFILL UNDER ROADS SHALL BE COMPACTED TO THEREQUIREMENTS OF THE LOCAL AUTHORITY.

14. ALL CONNECTION INTO EXISTING LOCAL AUTHORITY STORMWATER ARE TO BECARRIED OUT BY THE CONTRACTOR TO LOCAL AUTHORITY SPECIFICATIONS.

15. THIS STORM WATER DESIGN IS TO BE READ IN CONJUNCTION WITH THE BUILDER'SARCHITECTURAL DRAWINGS (PARTIALLY REPRODUCED HERE).

16. CLIENT IS TO ENSURE LOCAL AUTHORITY HAVE APPROVED THESE DRAWINGS BEFOREBEING ISSUED FOR PRICING, TENDER & CONSTRUCTION.
