2 David Low Way - Attachment 3 - Civil Engineering Assessment - Sheehy 10-8-17

2.7      Water

Unitywater provided a Services Advice Notice in February 2016 (SAN number 2016006791)
and advised that the proposed development is within Unitywater’s water supply connection
area and has a current service connection to the existing properties. Any changes required to
this service must be carried out at no cost to Unitywater.
Unitywater advised that watermains shall be provided along the full frontage of the
development site to ensure that mains extensions can occur without disturbing developed
footpath and the need for approval for works in roads. No future connection areas are identified
on the Unitywater Connections Policy 2016 Water Connection Area maps on the east side of
David Low Way south of the proposed development site to require further extension of the
water main. The extent of the proposed water main is therefore compliant with Untiywater
requirements.
The existing water connection is serviced from a 250mm diameter trunk water main located
within the gully of Burgess Creek. There is also a 250mm trunk watermain located at the
frontage of the development site within David Low Way. These Unitywater services are
identified on the Detailed Infrastructure Mapping included in Appendix E.
It is proposed to provide a new water reticulation main from the existing 250mm AC trunk
watermain in David Low Way and extend this along the full frontage of the development site
within the road reserve at an offset to the boundary to comply with Unitywater requirements
(1.5m). Each property will have a dedicated connection and water meter located within the
property boundary for future connection to the building. Individual crossings of the proposed
10m buffer area to the front of the site designated as the Covenant Areas P, Q, R, S, T and U
will be required. Connection can either be made to the building envelopes or left at the
boundary with provision made under the driveway for future connection when final building
development is approved.
The initial assessment has identified the feasible location and routing for the watermain
required to service the development site and is expected that a 100mm diameter PE reticulation
main will be required to service the properties. The initial assessment has also identified there
will be a need for an additional Fire Hydrant within the reticulation watermain to meet
requirements for firefighting within the development.
The proposed indicative watermain service is indicated on the General Layout and Services
Plan in Appendix B. No further formal discussion has been held with Unitywater in addition
to the Service Advice Notice received and a network analysis will be required to confirm
sufficient capacity is available within the existing system. The proposed development site lies
within the Unitywater Demand Projection Catchment for Sunshine Beach and has a current
water connection.

2.8      Electrical & Telecommunications Services

As the Electrical and Telecommunication Service providers are retail service providers, they
will upon request (and payment of charges where necessary) provide pipe, pits and cable to
service the proposed development site. Therefore, adequate servicing can be provided to the
proposed development site.
