Proposed amendments to FNQROC Development Manual (Water and Waste Water Sections only)

Presented by: Darlene Irvine, FNQROC Executive Officer

• 1. Welcome and Introductions
• 2. Overview of amendments to the manual

(Water and Sewer only)

• 3. CTM Code presentation - CRC
• 4. Focus in on areas / sections of interest
• 5. Amendments to Standard Drawings

• Search function is included on the FNQROC website
• New PDF versions will have hyperlinked table of contents
• Removed ‘Operational Works’ to limit confusion and referred to Planning Act

definition of ‘development’ in the user guide.

• While we’ve recommended to link the operational checklist I believe this will

go as IDAS Form 6 does this.

• Council may request (during the assessment) the digital ACAD file of the

water and sewerage reticulation drawings

• Documents to be provided prior to Pre-Start:
• Copy of ‘For construction’ drawings
• Pavement Design
• As Constructed submission; included DWG file
• Early plan sealing requests will only be considered for those stages of

development nominated in the development plan. Parts of a stage will not be considered for early plan approval.

• Appendix P – reduced requirement for as constructed attributes and split

into compulsory and only required if differed to FNQROC specs

• Replaced reference to WSA with CTM Water Alliance Design and

Construction Code

• CTM Code referenced in the manual
• CRC only – changes to Average Daily consumption – from 500 to 400 L/EP/D
• Adopted the Darcy-Weisback method over the Hazen-Williams method
• Creek crossings included in design Criteria:
• Ck crossings are to be in DICL or PE
• Arborist report to assess the risk associated with trees within 10m either side of the

water main alignment.

• New section for building over or near water infrastructure
• Marker balls to be used where water reticulation is laid on non-standard

alignment

• All irrigation connections to councils water network must be completed by

council at the developers cost. (if permitted, an approved subcontractor with council supervision)

• Pump Stations – at councils discretion - the provision of a three phase inlet

to allow the connection of a mobile generator unit.

• Factory acceptance testing is to be undertaken and the designer is to

arrange a suitable time and date with Council for testing before the switchboard is installed at site.

• Amendments made to CRC local government specific – D6.17 clause

removed.

• Incorporation of CTM
• Vacuum and pressure sewer schemes are still considered unconventional

infrastructure

• New section added for building over or near sewerage infrastructure
• Amendments made to value in table 7.2, and 7.3
• Property connections into maintenance shafts are not permitted unless in

circumstances approved by council

• On-site sewerage – new clause – the min separation distance between on-

site facilities and water mains is to be 10 meters.

• D7.16 General – new clause – where the calculated C1 value is less than 3.5

the pump operation mode is to be duty/assist. 3.5 and greater – is to be duty/standby – needs to be confirmed with Council.

• Well washers not required for CRC
• The requirements of fencing of pump stations is to be confirmed with

council.

• Standby generator is to be contained within a roof structure and wording to

include three phase inlet at council discretion.

• We ask that the design of the pump station considers measures to prevent

damage from vandals and restrict un-authorised access

• Factory acceptance testing with council before the switchboard is installed

at site.

• Table 7.14 – pump motor drive design parameters have been amended, a

new item related to sizing of overflow pipe added and we’ve replaced Hazen Williams formula with Darcey-Weisbach formula

• Variable frequency drives should be considered for pump stations that

discharge into a common rising main.

• Table 7.15 – replaced Hazen Williams formula with Darcey-Weisbach

formula

• Appendix A – contains addendums to the CTM Code
• Appendix B – contains addendums to WSA Code
• Amendments to CRC local government specific – deleted clauses D7.13 and

D7.25

• CTM Alliance Water Service Design and Construction Code incorporated
• Reference documents – WSA 2002 version of Dual Water Supply Systems
• Included reference to a number of AS
• Included stainless steel as a material
• Clarification re ductile iron
• Included the ability to use reglass material

• CTM Alliance incorporated
• Included ability to use reglass in bedding
• Included WSA construction tolerances
• Appendix A – references to SEQ Standard drawings
• CRC Local Government specific – delete clauses S6.03, S6.21, S6.23

• 43 standard drawings amended or new – available for viewing

• Reminder – we take submissions to amend the manual at any time – these

are collated for each review.

• Submission on the proposed amendments are due 22 September –

d.irvine@fnqroc.qld.gov.au

• Seeking legal advice to make the review process quicker and simpler.

Hand over to CRC re CTM code.
