Clearing the Way - Access into Shannon Creek Storage Site

Image date: 18th May 2006 & 22nd May 2006

Clearing of the 4.5km new section of access road, off Shannondale Road, into the Shannon Creek Storage site is underway. Contractors Vemco Pty Ltd are undertaking the work for North Coast Water, a business unit of Clarence Valley Council.

Clarence Valley Council in May this year accepted a tender by Leighton Contractors Pty Ltd, for construction of the 30,000 megalitre storage at Shannon Creek and associated work (including the storage, access road and power supply substation) - this major construction work is expected to commence in July this year, following approval by the Minister for Utilities to the award of the contract. This final stage of the Clarence Valley & Coffs Harbour Regional Water Supply Project construction is scheduled for completion in 2009. When filled, the storage will secure the water supplies for the Clarence Valley and Coffs Harbour areas on the north coast of NSW.

Dry times in the Clarence River at Carnham during the 1994 drought in the Clarence Valley

Dry times in the Clarence River at Carnham during the 1994 drought in the Clarence Valley

Image Date: 1994

Currently the water supply to the Clarence Valley has no significant storage capability and water is drawn from the Nymboida River on a continuous basis. Water from a weir on the Nymboida River is used for the operation of a hydro-power station (by Country Energy) and for water supply to the Clarence Valley (by North Coast Water). Water is piped from Nymboida to a 100 megalitre storage at Rushforth Road, South Grafton, where it is chlorinated and flouridated and then distributed to Clarence Valley consumers.

Water supply security during drought periods will be achieved by construction of a 30,000 megalitre storage at Shannon Creek, as part of the Clarence Valley & Coffs Harbour Regional Water Supply Project.

Community consultation has played an important role in the development of the Clarence Valley & Coffs Harbour Regional Water Supply Project. Five notable outcomes include:

  • A more comprehensive investigation into alternative water sources, including rainwater tanks and desalination;
  • A 20% reduction in the design water demands;
  • Introduction of the Regional Water Efficiency Program;
  • Relocation of the original dam site from Kangaroo Creek to Shannon Creek; and
  • A changed Project design horizon from 2046 to 2021, to facilitate the earlier introduction of applicable future technological advances in alternative water sources and possible changes to community attitudes to potable effluent re-use

Kangaroo Creek was initially the preferred site for a regional storage, prior to adoption of the Shannon Creek Storage site in July 1997. Due to environmental, economic, heritage and social considerations, the Shannon Creek site was selected as a more suitable storage site and is now one of the major components of the Regional Water Supply Project.

The Aboriginal community has been actively involved in the development of the Project, and is continuing participation through the Project's Aboriginal Liaison Committee.

Investigations into ways to augment the Clarence Valley and Coffs Harbour water supplies have been underway for more than a decade. Following many years of research by the Councils in the Clarence Valley and Coffs Harbour, in 1994 the Councils signed a Memorandum of Understanding agreeing to investigate a regional water supply scheme. North Coast Water (then known as Lower Clarence County Council - LCCC) undertook the co-ordination role and in 1995 Coffs Harbour City Council became a member of the LCCC. Comprehensive investigations and community consultation proceeded and in July 1997 the regional scheme including a new 30,000 megalitre storage at Shannon Creek (9km west of Coutts Crossing) and Approx. 90km of proposed underground pipeline, was adopted. In March 2000, after an extensive approvals process, NCW made the "Determination" decision agreeing to proceed with construction of the Project.

The Clarence Valley and Coffs Harbour Regional Water Supply Project will provide a secure bulk water supply to the region extending from Iluka in the north to Sawtell in the south, on the NSW North Coast.

Image Date: 23rd September 1999

An independent Environmental Commission of Inquiry for the Clarence Valley & Coffs Harbour Regional Water Supply Project was called by the project proponent (Lower Clarence County Council - North Coast Water). The Commission of Inquiry was conducted by Commissioner William Train in Grafton during August and September 1999.

Extract from the Commission of Inquiry Report Dec. 1999 (Executive Summary, p viii): "On weighing and balancing the evidence before the Inquiry the Commission is satisfied that the Regional Water Supply Project proposed by the Lower Clarence County Council has significant benefits for security of supply for the Clarence Valley and Coffs Harbour. The proposal provides a low cost supply which will have low flow protection benefits for the riverine systems of the Orara and Nymboida Rivers. Subject to the conditions recommended environmental concerns are not such as to preclude the Lower Clarence County Council determining to grant development consent."

Karangi Dam, Coffs Harbour's water supply

Image Date: 22 February 1999

Both the Clarence Valley and Coffs Harbour have water supply security problems expected to worsen as development continues, and the need to protect the health of the Nymboida and Orara Rivers is now recognised.

Coffs Harbour's primary source of water supply is the Orara River. Water is drawn by Coffs Harbour City Council, from the Orara River at Cochrane's Pool and pumped to the 5,600 megalitre Karangi Dam. Water from Karangi Dam is chlorinated and distributed to coastal developments from Sawtell in the south to Corindi to the north. During periods of low flow in the Orara River pumping is stopped and the water supply is drawn solely from Karangi Dam. These current arrangements are not able to supply the annual water needs of the Coffs Harbour area without frequent restrictions (every 2-3 years).

The Clarence Valley & Coffs Harbour Regional Water Supply is designed to service the Clarence Valley and Coffs Harbour to at least 2021 using existing sources at the Nymboida and Orara Rivers. The Project will provide a secure bulk water supply for the region and includes approx 90km of pipeline linking the Nymboida River, Shannon Creek Storage, Rushforth Road Reservoir at South Grafton and Karangi Dam at Coffs Harbour.

Shannon Creek Storage area

Shannon Creek Storage area

Since Eurpoean settlement, the Shannon Creek Storage site has been extensively cleared by grazing and agricultural activities over a prolonged period. Consequently, a high proportion of the understorey and ground cover vegetation has already been removed.

There are large areas of comparable or better quality habitat for all subject flora and fauna species outside the disturbance area of the new storage, and compensatory habitat is included in the project planning. Therefore, although direct impacts will arise from clearing for the storage, they are not predicted to cause populations of any species to become extinct in the study area.
