Water is our most precious resource

How can current and future generations protect this precious resource and use it sustainably?

One answer is to establish water stewardship strategies that anticipate, manage, and mitigate the potentially detrimental impact of water usage by a more closely-knit network of stakeholders.

Urbanisation, dietary and lifestyle changes are accelerating the water demand.  At the same time, water loss through leakage, mainly due to ageing infrastructure, is a significant issue in the developed and developing world.

Governments and companies embracing water stewardship practices and focusing on sustainable water management are increasing.  Water and sewerage companies worldwide are coming under pressure to do more with less, putting operational efficiency measures at the top of their agenda.

Companies that adopt water stewardship strategies should anticipate, manage, and mitigate risks such as increasing water costs, changing the regulatory landscape, or disrupting physical supplies.

Think global, act local

Communities must now deal with the impact of climate change, extreme weather patterns, population and economic growth, and ageing water and wastewater systems.

Some regions will see more flash floods with devastating consequences on human life, businesses, and infrastructure.  At the same time, in parts of the world, droughts may set in and become more prolonged, such as the droughts experienced in California in recent years.

Warmer weather will increase water demand, rising sea levels, and adverse weather patterns, resulting in significant societal changes, such as large-scale human migration.

We can advise on sustainable management techniques to protect water cycles and reduce the impact of human activity, optimising water and wastewater provision and consumption.

Emergency management planning and response

Our extensive experience providing support at flood incident control centres enables us to offer valuable insight to emergency managers in the form of information from our flood forecasting software.  Our assessments can advise on likely flood impacts on critical infrastructure such as roads and prepare flood warning communications. It can also be integrated with our planning model or used to inform traditional timeline assessments.

Our approach

Shared standards

We employ the personal integrity and technical expertise that underpin good environmental outcomes and defensible decisions.

Better data

We collect and analyse data efficiently, using it to fuel our environmental assessments, analyses, and proprietary modelling systems to deliver actionable insight.

Clear communications

We understand and speak to the different agendas of your stakeholders and keep you fully informed on progress.


Our credibility within the industry and reputation with regulators add weight to the submissions we make on your behalf.

Systems framework for water and environment

A key element in designing environmental monitoring programmes is determining thresholds, beyond which there is a risk of unacceptable ecological impact. Our expert knowledge and extensive experience mean we understand and identify ecological cause and effect pathways to help you set the suitable threshold.

Some examples of thresholds and associated sectors that we work for include:


  • Sediment infauna - based on organic carbon deposition rates
  • Phase-shifts from coral to macroalgal dominated communities – based on biologically available nitrogen

      Desalination and wastewater outlets

  • Coastal macroalgal and marine plant communities - based on biochemical signatures and community composition
  • Physicochemical triggers such as salinity, nutrient and temperature (loads and concentration)


  • Sediment and light thresholds for benthic communities such as seagrass, corals and spawning fish
