Summary

Forty-one of the 59 harbour swimming sites complied 100% with Beachwatch criteria for faecal coliforms and enterococci during the 2008–2009 summer season (Figure 20 and Figure 21). These results are among the best ever recorded, just behind summer 2006–2007, when 43 harbour beaches complied 100%, and summer 2005–2006, when 51 harbour beaches complied 100%.

Results for summer 2008–2009 were a vast improvement on summer 2007–2008, when extreme wet weather conditions resulted in only ten harbour swimming sites complying 100%.

With a return to average rainfall in summer 2008–2009, improvements in water quality were recorded at 47 swimming sites. Compliance increased for one or both indicators at:

  • Salt Pan Cove Baths, Winji Jimmi Bay, South Scotland Island and Elvina Bay in Pittwater
  • Little Sirius Cove, Clifton Gardens, Redleaf Pool, Rose Bay Beach, Parsley Bay, Watsons Bay, Forty Baskets Pool, Manly Cove, Little Manly Cove, Davidson Reserve, Gurney Crescent Baths, Sangrado Baths, Northbridge Baths, Clontarf Pool, Chinamans Beach, Edwards Beach, Balmoral Baths, Tambourine Bay, Woodford Bay, Woolwich Baths, Cabarita Beach, Henley Baths, Chiswick Baths, Dawn Fraser Pool and Greenwich Baths in Sydney Harbour

Enterococci compliance increased at Cabarita Beach (32 percentage points), Henley and Chiswick Baths (23 percentage points), Dawn Fraser Pool (19 percentage points) and Greenwich Baths (16 percentage points).

Lower Georges River

Faecal coliform compliance

Two of the six lower Georges River swimming sites recorded 100% compliance with Beachwatch criteria for faecal coliforms during summer 2008–2009 (Figure21). High compliance was also recorded at Como Baths (97%), Oatley Bay Baths (94%), Sandringham Baths (94%) and Jew Fish Bay Baths (91%).

 

Improvements in faecal coliform compliance from the previous summer season were recorded across all sites in the lower Georges River.

Enterococci compliance

Dolls Point Baths in the lower Georges River recorded 100% compliance with Beachwatch criteria for enterococci during summer 2008–2009, an improvement of nine percentage points from the previous summer season (Figure21). Good compliance was also recorded at Sandringham Baths (94%).

Carss Point Baths improved by 29 percentage points from the previous summer season to reach 88% compliance. Como Baths remained at 84% compliance, the same as in the previous season.

 

Although a fall in compliance (three percentage points) was recorded at Jew Fish Bay Baths, the site still complied well (84%) with enterococci criteria. Lowest compliance (69%) was recorded at Oatley Bay Baths, a fall of three percentage points from the previous summer season.

Botany Bay

Faecal coliform compliance

Five of the nine Botany Bay swimming sites recorded 100% compliance with Beachwatch faecal coliform criteria (Figure21). The exceptions were Brighton-le-Sands, Kyeemagh Baths and Frenchmans Bay which also recorded high compliances of 97%, 97% and 91% respectively.

 

Improvements in faecal coliform compliance were recorded at six sites in Botany Bay. These were Frenchmans Bay (19 percentage points), Kyeemagh Baths and Ramsgate Baths (13 percentage points each), Monterey Baths and Silver Beach (12 percentage points each) and Brighton-le-Sands (nine percentage points).

 

Access to Foreshores Beach was limited during summer 2008–2009 owing to construction works at the site. As a consequence compliance with faecal coliform criteria could not be calculated because an insufficient number of samples was collected within the required period.

Enterococci compliance

Four of the nine Botany Bay swimming sites recorded 100% compliance with Beachwatch enterococci criteria (Figure21). High compliance was also recorded at Ramsgate Baths (94%) and Brighton-le-Sands (97%), a decline of six and three percentage points respectively from the previous summer season.

 

Enterococci compliance improved by nine percentage points at Yarra Bay to 75%, and by 22 percentage points at Frenchmans Bay to 78%, from the previous summer season.

 

Access to Foreshores Beach was limited during summer 2008–2009 due to construction works at the site. As a consequence compliance with enterococci criteria could not be calculated because an insufficient number of samples was collected within the required period.

Port Hacking

Faecal coliform compliance

All five Port Hacking swimming sites recorded 100% compliance with Beachwatch faecal coliform criteria during summer 2008–2009 (Figure21).

 

Improvements in faecal coliform compliance were recorded at four sites in Port Hacking. These were Gymea Bay Baths (25 percentage points), Gunnamatta Bay Baths (19 percentage points), Lilli Pilli Bay Baths (12 percentage points each) and Horden Beach (nine percentage points).

Three of five swimming sites in Port Hacking recorded 100% compliance with enterococci criteria during summer 2008–2009. Gymea Bay Baths and Horden Beach also recorded good compliance with 94% and 97% respectively.

 

Improvements in enterococci compliance were recorded at three sites in Port Hacking. These were Gymea Bay Baths, up by 28 percentage points, and Gunnamatta Bay Baths and Hordens Beach, both with an increase of six percentage points.

Plans for improvement

Sewage overflows – SewerFix

Sydney Water is required by DECCW Environment Protection Licence conditions to manage sewerage treatment systems efficiently, in order to protect and minimise harm to the environment and public health. The licences aim to minimise the frequency and volume of overflows and sewage treatment plant bypasses by identifying limits and targets for sewage overflows as well as measures to require further overflow abatement.

 

Details on SewerFix, Sydney Water’s 20-year program for maintaining and improving the sewer system, are presented in Chapter 2.

Stormwater

From 2006 to 2008 the Environmental Trust provided over $19.8 million for 26 projects to improve the condition of degraded urban waterways through rehabilitation and restoration activities. Grant funding was made available by the NSW Government’s Environmental Trust Urban Sustainability Program, through the Urban Sustainability Major Projects and Urban Waterways Initiative. Grant funding is targeted at local councils working with the community and business to protect and improve the urban environment. Priority catchment areas for the Urban Waterways funding stream include the Cooks River, Georges River and Sydney Harbour.

 

The projects implemented include initiatives such as stormwater reuse schemes, water-sensitive urban design, and activities to restore streams and creeks in various local government areas, thus improving local water quality and overall catchment health. These projects have also included the implementation of education and engagement programs to maintain the health of urban catchments.

 

The NSW Government’s Urban Stormwater Program was established in 1997 and concluded in 2006. A total of $82 million in seed funding was provided to address stormwater quality hotpots and to give the stormwater industry and stormwater managers opportunity to develop new ways of addressing poor stormwater quality and ameliorating its impact on receiving waters.

 

The major outcomes of the NSW Government’s Urban Sustainability Program, Diffuse Source Water Pollution Strategy and Urban Stormwater Program, together with details of Sydney Water’s investment in stormwater improvement are presented in Chapter 2.
