Subject: SR356224 - 79 Taranaki Road - Consent Notes Rev A
Hi Peter
Please find attached revised drainage notes for the resource consent - correcting the equivalent number of properties and clarifying the WW options.
WWL have confirmed that there are no capital works planned to upgrade the WW mains in the vicinity of 79 Taranaki Road.
As mentioned previously the capacity assessment is based on the receiving WW main 150mm dia. Capacity issues would still exist if the WW main were 225mm dia. The actual size of the main requires confirmation on site. I will get this confirmed.
To facilitate the WW discharge the applicant will either need to:
· Upsize the offsite WW network sufficient to accommodate the increase in WW flows – the length of the upsize would need to be confirmed.
· Store WW flows on site and pump out during off peak periods.
I’m happy to discuss this further with the applicant if that helps them to confirm a way forward.
Cheers

Hi Peter
We spoke Friday regarding this one.
I’ve spoken with Sheryl this morning (via email). She has confirmed that:
· Further investigations are required to confirm the extent of the WW capacity issue and how this would be resolved.
· The developer is required to mitigate the impact of the increase in WW discharge, depending on the outcome of the investigation this might mean upsizing a length of undersize WW main or onsite WW storage with pumped discharge.
· Given the location of the proposed development an off-site solution might be complicated / costly to achieve and the applicant is advised to allow for WW storage and pumping.
The notes attach simply state that the system is under capacity and that mitigation works will be required.
Cheers
