Services / Environmental



We provide leading technical services in the fields of stormwater treatment, hydraulic modelling, localised flood analysis and Integrated Water Management (IWM).  Our aim is to facilitate sustainable management of water,  reduce impacts on the environment from the development and construction industries whilst achieving acceptable social and economic outcomes.

Stormwater Management and Integrated Water Management (IWM)

Stormwater management is necessary to mitigate impacts from development on the health of downstream waterways and also to control adverse drainage impacts to upstream, downstream or adjoining properties.  Our stormwater management services range from small development works to feasibility studies and designs for major catchments incorporating best practice water sensitive urban design.

Overland flow, flood analysis and hydraulic modelling

Westera Partners provides flood reporting on various scales from single residential lots to river stream analysis and hydraulic structures design Often the purpose of flood reporting is to determine building floor levels and to identify any impacts to upstream or downstream or adjoining properties from potential developments. We pride ourselves on accuracy of reporting and apply great emphasis on developing cost effective solutions to flood affected developments. Our flood related services include: 
  • One- dimensional river hydraulics modelling 
  • Overland flow flood studies 
  • Major hydraulic structures design including large culverts 
  • Risk assessments

Risk Assessment

Risk assessment is a necessary tool which can be applied when developing master plans for large scale development and also when identifying project concepts for small scale developments.  Legislation also requires a more integrated whole of life risk based approach to safety in design on all projects over $250,000.  Westera Partners combined expertise in the structural, civil and environmental fields enables detailed master planning of large scale developments in relation to water supply, wastewater network, stormwater management, and civil infrastructure including roads, bridges and culverts.  Risk assessment is often teamed with multi-criteria analysis to identify options able to best meet the desired triple bottom line.
