What is Stormwater Pollution?

When it rains, water system flows from your roof, yard, and course into the gutter and down the drain. The stormwater drain motorcarries this water into Lake Macquarie, wetlands, lagoons and the ocean along with either the deposit, folderol, grass clippings, caress faeces, chemicals and fertiliser it collects along the way. The result is stormwater pollution. tolerate circumscribed 20-AUG-2009 What impact is stormwater pollution having on Lake Macquarie? Volumes of stormwater in urban argonas develop increase up to 40 times above natural levels due to the change magnitude atomic number 18a of impervious surfaces such as rooves, roads, and driveways.The increase in sight causes our creeks to rise higher and flow faster, eroding the banks and bed of the creek carrying change magnitude sediment and nutrients into the Lake. It is estimated 57,000 tonnes of sediment is washed into the Lake all(prenominal) year, nine times more than when the Lake was surrounded by bushland. We all live in a water catchment and our every-day activities affect the quality of the Lake and ocean. When many people carry out the analogous activity, the cumulative effect plunder be great.For example, the 45,000 pet dogs in Lake Macquarie force about 9 tonnes of faeces every day. The impacts of stormwater runoff may take the loss of recreational amenity, the destruction of seagrass beds and aquatic habitat, and the growth of algal blooms. Last Modified 20-AUG-2009 What is the Lake Macquarie Stormwater Management externalize? The Lake Macquarie Stormwater Management Plan (SMP) was prepared in 1999 in response to a directive issued to all NSW Councils by the environment Protection Authority.The SMP provides a framework for improved stormwater management and establishes opportunities to promote reconciling action by Council, stormwater managers and the community. It outlines planning and strategy measures such as requiring modern developments to come down the flow of sto rmwater off their sites. It sets out specific works that are required to stop erosion and water pollution, such as the plait of stormwater quality devices (SQIDs) around the Lake. It sets out monitoring programs to measure the amount and do of stormwater pollution and the effectiveness of management programs.Education of the community to increase their sense of the issues and to change behaviour is the fourth element of the SMP. Many actions in the SMP fork up already been implemented. In 2004 the remaining actions were reviewed and incorporated in the Lake Macquarie Environmental exploit Plan.

Stormwater issues were identified through a community workshop, catchment audit, and Councils estuary management program.They acknowledge Environmental Issues Elevated nutrient levels particularly in foreshore areas Elevated levels of bacterial pollution particularly after rainfall Increased loads of sediment causing plumes of dirty water after storms Accelerated catchment erosion particularly in creeks and foreshore areas Loss of habitat values due to impacts on seagrass and bushland environments Discharge of environmental pollutants arising from industrial and commercial premises Litter pollution mainly spy in creeks and foreshore areas.Aesthetic values of the stormwater system amenity of concrete stormwater devices is in the main low Community understanding of stormwater issues changes in attitudes and behaviours are required to reduce stormwater pollution Managerial Issues Ad-hoc approach to stormwater management consistent standards and policies required wishing of defined objectives for stormwater management targets need to be established Stormwater system ground on hard engineering designs and end-of-pipe solutions source control and soft engineering options need to be implemented as a pr iority.Last Modified 11-NOV-2010 How has the Stormwater Management Plan be implemented? Council, State, and Federal Governments have spent more than $1million each year since the SMP was adopted building stormwater quality improvement devices (SQIDs) and erosion controls. appoint winning projects such as the Salts Bay Save the rain downforest from the Rain project have provided examples of how residents and Council can install sustainable stormwater systems. The new information Control Plan 1 requires new developments to catch and treat stormwater on site.Stormwater management is a responsibility shared by everyone who lives, works or plays in the Lake Macquarie catchment. The community has an important role to play in the death penalty of the Plan. This may involve changing everyday behaviours to reduce the potential for stormwater pollution, for example, by reducing fertiliser use when tending. As well, government and non-government authorities have a key role to play includi ng Council, Hunter Water sens (HWC), Roads and Traffic Authority (RTA), and Wyong Shire Council.Last Modified 20-AUG-2009 What can you do to encumber stormwater pollution? We can all help to prevent stormwater pollution by preventing pollutants from entering the stormwater system. At home Wash your car on the grass and use a small amount of detergent or none at all. Dispose of unwanted paints responsibly at an approved collection point for proper disposal. Place used readying rock oil in a carton or jar and cast off of when full in garbage bin. Take used motor oil to service station that collects it for recycle purposes.Make sure litter cannot spoil out or fall out of garbage bins or recycling containers. In the garden Reduce use of garden fertilisers and ensure they do not runoff into gutters or drains. Collect and properly dispose of pet droppings down the toilet or put them in the garden. batten down that you have good grass cover in your yard to prevent soil being washed into the stormwater system. Create a worm rise and compost your grass clippings and garden cuttings. Handweed or mulch to control widows weeds rather than using chemicals. Incorporate safe pest control into your garden practices.At work Reduce, reuse and recycle waste products from your office including paper, take out cartons, glass, aluminium and vegetable scraps. In the neighbourhood Help protect and mend natural wetland areas. Help protect and repair foreshore and riparian (creek-bank) areas. Put your rubbish in garbage bins provided or take it home when you are bushwalking, picnicing or at the beach. Get involved with a Landcare or Coastcare group and make pass the weekend with friends restoring native vegetation in riparian lands, wetlands and beach dunes.
