WEBINAR: Sustainable Water Management Practices for LAs

WEBINAR: Sustainable Water Management Practices for LAs


Join us for this national webinar on sustainable water management practices for landscape architects presented by ACO.  This webinar will feature a case study of a project on the NSW Central Coast presented by Mark Liebman, Director of Sustainability Workshop.  

Deciding how stormwater is managed can have lasting effects on a project’s success.

Water Sensitive Urban Design (WSUD) aims to improve the ability of urban environments to capture, treat and reuse stormwater before it has the chance to overburden existing systems and pollute and degrade our creeks and rivers.

Treating stormwater ‘at the source’ is a fundamental necessity for protecting our water supply, preserving natural ecosystems and replenishing the natural water table. By removing contaminants and pollutants at the point where water is collected, we can minimise the release of harmful pollutants into the environment. 

To achieve this, underground temporary stormwater storage has become vital to consider not only for stormwater detention (OSDs) but increasingly for stormwater reuse (retention) and infiltration.

This presentation is about geocellular stormwater management. A method successfully used in applications across all construction environments as a standalone solution or as part of a WSUD scheme, both in private and in public urban spaces.

Join industry experts as they explore the reason why underground stormwater management has become so important. We will discover a recent case study where Central Coast Council, NSW elected to treat stormwater directly ‘at the source’ compared with the conventional approach for an ‘end of pipe’ design.

Key messages:

  • Type of plastic tanks, legislation and standards
  • Structural, storage capacity & System versatility
  • Geomembranes, geotextile wraps 
  • Access, inspection, logistics & site-specific topics
  • Natural water balance v. urban water balance v. WSUD water balance
  • Infiltration a solution to the urban stream syndrome
  • Sydney Avenue, Umina Beach case study

This CPD course is suitable for all landscape architects, urban planners and designers. You do not need to be an AILA member to attend.

The event will be held 12pm - 1pm AEST.
