Hi Ken,

Thanks for your email.

In regards to the connection across Tamaki Road, Healthy Waters’ preference would be to redirect the existing DN225line and catchpit lead that cross Tamaki Drive so as to minimise the number of road crossings, if this is feasible. If this isdone, we request that the abandoned pipe is filled with grout and shown as abandoned on the Council GIS.

Otherwise, no further comments from me.

Many thanks,

Hi David and Sophie

Thank you for the feedback.

My comments as follows:

Item 1We do not seek HW’s approval as such however we do seek acknowledgement that our stormwater disposal andmanagement proposal is on the right track.

Item 2Flooding and coastal inundation has been dealt with separately by Tonkin and Taylor although I am not sure who theyhave been dealing with at Council. Perhaps Scott can assist in this regard.

Item 3We have proposed the new DN450 stormwater connection across Tamaki Drive for the following reasons:

1. It will provide the deepest point of connection and therefore provide the best level of service to the proposedbuilding.

2. It is anticipated that it will be able to be construction using trenchless methods thereby minimising thedisruption that excavating across Tamaki Drive would otherwise cause.

3. It will reduce the load on the existing upstream systems to the maximum extent.4. There is also potential to redirect the existing DN225 line and catchpit lead that cross Tamaki Drive so as to

minimise the number of road crossings.

I would be more than happy to meet to discuss this matter further.

Hi Ken,

Attached is Sophie’s review of the proposal.Sorry for the delay, I hadn’t had a chance to have a look through it.

Sophie has a question regarding the proposed new line at the bottom of the memo.

Further to note about the site, which was not addressed in the memo, is that it is within a 50 ARI coastal inundationevent. Look through TR2016-017 Coastal Inundation by Storm-tides and Waves in the Auckland Region for the waterlevels.

Yet another two weeks gone by and still no response re stormwater.Do you realise that our request for advice was made on 14 December last year. Please explain the delays.

Hi Ken,

Attached is WaterCares review of the proposed development. Note, they have conditioned that the pipe be upgraded atthe cost of the developer.

Unfortunately this appears to be WaterCare’s final decision. Council cannot be of much help with altering their decisionand it might be best to arrange a meeting with them in person to discuss this further.

Sophie will get back to us soon regarding the stormwater situation and what you are proposing.

Hi David/James

We have no intention of upgrading any infrastructure that we are not directly responsible for.

The wastewater line in question appears to be already quite overloaded and we will be adding to it only very slightly sowe are only responsible for our fair share at most.

Hi David,

I am not aware of any upgrading plan for that.

Since I could not see any overflow recorded near that section for the past a few years, I doubt upgrading of the sectioncan be in the high priority list.

However, applicant can contact with WSL planning team if they want.

Thanks James,

Just with regards to the capacity of the line. Are there upgrades planned for the line or should the applicant upgrade theline themselves?

Hi David,

We have checked flow capacity again for that 150mm sewer section between MH (ID: 514580) and MH (ID: 514581)along Atkin Avenue.

Based on applicant’s calculation, the existing 111 dwellings contribute PWWF 7.63 L/s into Line 1. The additional flows,from existing 40+ dwellings downstream Line 1 can contribute approximately PWWF 2.5 L/s. This will make the existingcombined flow of PWWF >10 L/s.

The proposed new addition of 96 units will add another PWWF 6.88 L/s. So, post development will require over 16 L/s ofcapacity to this section.

However, based on the available grade of this 150mm section, the maximum PWWF capacity is around between 9-10L/s.

Therefore, it is well over this line’s capacity.

Kind regards,

Hi James,

Did I forward the below email to you already? I’m so sure I did but the past is becoming very hazy.

Further, here is an update from the applicant on 23/01“The following is an assessment of the hydraulic effects that the proposed development will have on the subjectwastewater line:

8

Increase in PWWF = 4.06 l/sIncrease in hydraulic gradient = 0.072% (based on DN150 pipe, k = 1.5mm)Increase in upstream head depth = 18mm (based on pipe reach length = 25.0m)

This demonstrates that the effects of the proposed development will be minimal, irrespective of current performance ofthe subject line. That is, the increase in the height of the upstream hydraulic grade line by only 18mm is extremelyunlikely to unduly worsen the existing situation.

I trust that this will satisfactorily address WSL’s concerns on this matter.“

Hi David

Thanks for the feedback but it seems a bit unfair that WSL expect us to do region wide assessments of its owninfrastructure which it should already know as a utility network operator.

It also seems obvious that the additional 4 l/s that the proposed development will generate will be insignificantcompared to the existing flows generated by the much larger catchment of the line in question. This also means that ifthe line is already under capacity, which I suspect it is, then who will be responsible for upgrading it.

Otherwise, could you please check to see if WSL has any information on the line, particularly its gradient. If not then wewill need to undertake a field survey which will be very costly because of the temporary traffic control requirementedand present an otherwise avoidable H&S risk.

Your assistance with this matter is much appreciated.

Hi Ken,

Just heard back from WaterCare, nothing from HW yet.

“I have done an initial check on this application.

What we are concerned is further downstream along Atkin Avenue, the sewer section is highlighted as per the attachedsheet.

With the flows coming from upstream of MH (GIS ID: 514580) from north direction, plus the total projected flow coming throughLine 1 (as stated in Appendix B, Preliminary Water & Wastewater Report), the short 150mm section between MH (GIS ID: 514580)and MH (GIS ID: 514581) can be a capacity constraint.

For this, we need applicant to do a catchment suttee to include flows coming from the upstream of MH (GIS ID: 514580) from northdirection.

Kind regards,


“

Hi Scott

As discussed at our meeting in October please find attached preliminary Stormwater and Water & Wastewater Reportssupplied with a view to obtaining pre-approval, in principle, from you, Healthy Waters, and Watercare Services for theseaspects of the proposed development.

The preliminary findings of the reports are that the local infrastructure has sufficient capacity to service the proposeddevelopment however we also wanting to establish if there are any wider capacity, or other, issues that could undulyaffect it.

I would be more than happy to attend meetings and or provide any further information to facilitate this matter.
