wastewater disposal and water supply preliminary report woodlane

1. PROJECT APPRECIATION
1.1 INTRODUCTION
The Woodlane wastewater disposal and water supply schemes were originally
proposed to be constructed by Mr Desmond Murray and Pat Wynne as part of
their residential sub-division development with development act approvals
obtained from The Rural City of Murray Bridge in April 1997. The schemes
were commissioned in 2001. The schemes were then handed over to The
Rural City of Murray Bridge, serving 40 new residential properties and 19 preexisting
shacks. The schemes were developed along the Murray River
immediately above the 1956 flood level. The land was previously utilised as an
orange orchard.
Copies of the Development Act Approvals (development number 415/240/96)
issued by Council are attached in Appendix F for reference.
The consultant engaged to undertake the project was Secon Consulting
Engineers (former Hutt Pike and Associates), with Robert C. Frazer and
Associates Consulting Engineers as the Civil Engineer. Norman Waterhouse
was engaged by Council to be their legal solicitor for this project.
The Woodlane wastewater scheme consists of two separate collection
networks. One services the new housing development along North Bokara
Road and Woodlane Drive, which comprises a network of gravity drains with a
connection point provided to each property within the scheme limits. There are
no on-site septic tanks within the sub-division and all sewage gravitates directly
to a single pump station at a low point in the system along North Bokara Road
in front of Lot 34. It is then pumped through a rising main to a wastewater
treatment plant approximately 1.3km south of the development at Lot 50
Woodlane Drive Hd Mobilong at about 53m AHD. Treated effluent from the
plant is then disposed of on a nearby woodlot.
The other network services the existing (as at 1997) shacks closer to the river
along Mathews Court with a connection point provided to each shack,
bypassing the existing septic tanks. The effluent gravitates directly to a second
pump station along Mathews Court near Lot 11, from where it is pumped
through a separate rising main to the sub-division pump station.
