One Water

We think differently about water. As global supply and demand for water intensifies, solving the world’s most complex water challenges demands different thinking – and that’s where we come in.


Water is one natural resource we all share. It’s used in every industry and the demand for it is only increasing as global population soars, precipitation patterns change and competition for water resources intensifies.

What if we showed you how, with a “One Water” mentality, we’re giving communities, industries and regions the resource they need to flourish and expand?

Jacobs is working with our clients to focus on adaptable, resilience-based planning and embracing a more integrated approach to water management called?One Water.

One Water integrates the planning, implementation, and operations of the built and natural water cycle. It provides a structured approach for considering and optimizing the complete water cycle including surface water, groundwater, desalination, stormwater and flood management, conveyance, wastewater, reuse and environmental flows. It goes beyond the water utility to balance the water-energy-food nexus and the wider community of water users.

One Water engages the full range of affected stakeholders, communities, businesses and the environment.?Forward-thinking cities and water utilities are taking a more integrated approach to water system challenges, working across silos to bring together the many stakeholders required to deliver future water sustainability. This starts with inclusive, engaged planning, considering the whole water cycle and the needs of all those who influence or are influenced by water resources.

Getting started

How does the One Water lens fit your community?

The underlying goals, objectives, and principles of One Water are similar for each community. Implementation of the approach is customized to address your unique attributes, environment, and economic conditions. Whether you are a single service provider (water, stormwater, wastewater,) or a multiple service provider, One Water will provide you unrealized value. Jacobs’ clients have recognized the following value with using the One Water approach.

  • Recognizing the circularity of local economies and finding opportunities for successful public-private partnerships.
  • Consolidating policies and ordinances that benefit multiple utility services while supporting economic growth and redevelopment.
  • Establishing measurable short-term and long-term goals applicable to local and regional comprehensive plans.
  • Determining trigger points for future actions and investments associated with climate adaptation and resilience.
  • Repurposing traditional waste as a valued resource (such as using biosolids to produce energy or using reclaimed water to augment potable water supplies.)
  • Incorporating innovation and lessons learned from other One Water initiatives.
  • Calgary downtown over water
    One Calgary, One Water

    Working with the City of Calgary's water utility, Jacobs is evaluating potential impacts of drought on various systems as part of the “One Calgary, One Water” framework. In addition to assessing infrastructure systems for Canada's third largest city – water supply and distribution; wastewater collection and treatment; stormwater and green infrastructure – the team assessed the vulnerability of meeting municipal agricultural and environmental demands; utility financial and governance systems, customer and community systems; and the broader regional community. Strategies to mitigate critical risks are being developed and prioritized for near-, mid-and long-term actions.

  • Engineers at a wastewater plant
    St. Petersburg, Florida

    Jacobs is working with the City to develop a capital program that addresses St. Petersburg's challenges today and into the future – including utilizing stormwater as a resource. A One Water, consolidated and integrated approach will result in cost savings from economies of scale as well as regional collaboration opportunities. One Water is a sustainable approach to long-term utility planning that considers the potential impacts resulting from climate change; salt water intrusion; infiltration and inflow; clean energy usage; greenhouse gas reduction; regional construction coordination; and mitigation of surface water impacts. It requires the City to rethink how capital priorities are set. Utility systems cannot be considered in silos any longer.

  • Sustainable Water Initiative for Tomorrow (SWIFT)
    Sustainable Water Initiative for Tomorrow

    The coastal region of Virginia is one of the U.S.’s regions most at-risk of devastating climate variability effects such as storm surge flooding and sea level rise.


  • Tuas Nexus rendering

    Singapore’s Public Utilities Board (PUB) and Jacobs turned water vulnerability into an international model for water management that extends across all facets of the water cycle.

“A one water approach opens our teams to view all water as a resource, not as stormwater, wastewater, drinking water or water for industry but as one water; we really start to innovate when we engage with digital, health or the environment teams. From the largest water supply project in California to overflow control in London to total water management in Singapore, with a one water mindset, our teams work to protect and give communities, industries and regions access to the resource they need to flourish and expand.”
