25 Kauri St, Cooroy                                                      360 Civil Consulting Pty Ltd


corner of the lot and connects to a sewer reticulation main on Olivine St on the opposite
side to the development site.

The north-eastern corner of the lot is the high point of the lot and achieving a connection
into this sewer would not be achievable without significant fill occurring over the site. It is
not proposed to connect into this sewer reticulation main.

Achieving a sewer connection to the Olivine St sewer reticulation main would also result in
additional fill over the site.

The preferred connection for the site is a new sewer connection via an extension of the
sewer reticulation main from Agate St to the north-western corner of the development site.
This proposed sewer alignment is indicatively shown on 360 Civil Consulting Drawings P01
and P02.

The development will be serviced via a new 150mm dia house connection branch from this
new 150mm dia sewer reticulation main.

A review of Unitywater’s Netserv Plan Planning Assumptions Mapping indicates that the lot
has an ultimate development allowance of 30.97EP which is anticipated to be sufficient to
service the proposed 17 unit development.

An application to Unitywater for the sewer reticulation extension and new house
connection branch will be required.

    13. Water Connection and Fire Hydrant Location
The Dial Before You Dig water infrastructure plan for the development site is contained in
Appendix C. There is an existing 300mm dia AC trunk water main located along the Olivine
St development frontage. There is also an existing 200mm dia AC water reticulation main
along the southern side of Olivine St and an existing 150mm dia water reticulation main
along the western side of Kauri St. The development site has an existing water meter
located halfway along the Olivine St frontage. This water meter will need to be upgraded to
a master meter (by Unitywater) and sub-meters will also be provided for each unit (by the
developer). The existing water service crossing may need to be upgraded to accommodate
the master meter. All costs associated with the water master meter upgrade and sub-meter
installation will be borne by the developer.

There are two fire hydrants on Kauri St opposite the development site and two fire hydrants
on Olivine St opposite the development site. No new fire hydrants are proposed to be
installed external to the site. Internal fire protection requirements will be addressed during
the detailed design stage by the building hydraulics designer.
