Autumn outlook

The Bureau of Meteorology (BOM) predicts equal chances of above and below median rainfall for most of Queensland, with 56% chance of totals exceeding 320 mm for the three-month period in the Sunshine Coast region. Above median maximum temperatures are very likely. High intensity rainfall events and storms are still possible. This means you need to make sure your site is prepared for storms and predicted rainfall.

Small building sites

Erosion and sediment control is not just for large development sites!

Residential building sites can wash pollutants into the surrounding environment. This includes soil (earth), concrete wash out waste, plaster wash, and general rubbish, polystyrene and food packaging. This pollution can damage ecosystems and reduces water quality impacting recreational activities. It can also block drains and bio retention basins, causing flooding. 

The same law applies to small residential building site with fines of up to $11,610.
(Environmental Protection Act 1994 440GZ)

To help you get your site right we have recently updated our factsheets and checklists.

These are our top tips on how you can protect our waterways and increase compliance:
  • Prevent Erosion - Keep disturbed and exposed soil covered with turf or landscaping and cover your stockpiles.
  • Control Drainage – Install temporary or permanent downpipes as soon as practicable to minimise runoff
  • Capture Sediment – Install adequate controls to ensure no sediment and site runoff leaves your site (for example, sediment fence). Install stable site entry/exit (for example, rock pad from the kerb to the slab to prevent workers and vehicles from dirt tracking offsite.
  • Stop the litter - Ensure site litter and waste is disposed of appropriately (for example, in a skip bin). Ensure waste that is easily wind dispersed is covered and do not overfill bins.
  • Waffle pods: Secure waffle pods so they cannot be blown off site and remove excess waffle pods as soon as practicable.

Builders Breakfast Aura 8 May 2024

 
To launch our updated factsheets, we are having a Builders Breakfast event in Baringa.  

Join the Construction Management and Waterways Protection Team along with colleagues from the Environment team and Healthy Land and Water  team over a sausage sizzle.

Find out about best practice erosion and sediment control and how to comply with requirements in the Sunshine Coast region.  

Managing concrete on Building Sites

Concrete and plaster runoff can be very harmful to the environment and needs to be contained.  The high pH levels, and additional chemicals may cause fish kills, impact ecosystems, and contaminate waterways as well as impacting the effectiveness of Bioretention Basins and Tree Pits resulting in flooding.
One bucket of concrete wastewater washed down a stormwater drain can wipe out hundreds of fish, with some streams and rivers taking more than a decade to recover from a single pollution incident.  

Top tips for managing concrete wash on building sites:
  • Keep excess water away
  • Wash concrete trucks and pump out trucks at a licensed facility
  • Capture or divert runoff into a sealed trench-like system, lined with geofabric or other filter media, away from drainage lines.
  • Ensure runoff is disposed of at a licenced facility for treatment. Do not let it wash down the roadside gutter or stormwater drains.
  • Dispose of excess concrete away from drainage lines and into a designated sump, bunded area, waste bags or large container (for example, IBC).
  • Use on-site waste removal such as a sucker truck or send back to the supplier for re-use.
