Thanks Sarah, Hywel

Hi Sarah, based on 2012 COP the 150mm pipe work downstream of this site is undersized. It would be a good idea to get Kevin to confirm the pipe sizes in this part of the network. Notwithstanding 225mm pipework is also undersized.

Hi Hywel
David Wilson suggested I contacted you about this site – he seems to think you might have a WW model for this area.
I’m looking at this RC for Sheryl Barker, The site is 79 Taranaki Street. The site and existing WW discharge lateral are showing on the attached GIS extract.
The applicant is proposing to convert 5 floors of office to ‘residential’ accommodation.
Pre Development
The current office floor plans show 2 ‘toilet’ areas per floor with a total of 4 urinals, 7 basins, 7 toilets, and 2 cleaners sinks – so not much. Office floor area (including the toilet space) is 841m2 over 6 floors (one floor will remain as office after the conversion) giving a total floor area of 5046m2.
Post Development
1 floor will remain as office – 841m2.
5 floors will be converted to ‘residential’. This is however high density 1 to 3 bedroom appartments.
Floors 1 – 4 will have 25 beds, 14 bathrooms and 14 kitchen units - I haven’t looked at flows but if you took beds alone this would be equivalent to 8 x 3 bedroom houses.
Floor 5 will have 8 beds, 9 bathrooms and 2 kitchen units – so again based on number of beds – 3 x 3 bedroom houses.
So expecting quite a significant increase in off-site WW discharge.
Is it possible to check if this will cause any capacity issues.
Please feel free to get back to me if you need any further information.
Thanks
Zeean Brydon. Associate Engineer
