Water is one natural resource we all share. It connects us all — and it affects us all.
Within and across watershed and community boundaries, our clients are tackling complex challenges as they look to sustainably, equitably and safely manage their water resources. Addressing these challenges requires integrated solutions specific to the regional watershed that are beneficial to local communities and rooted in the context of the global water cycle.

“At Jacobs, we recognize water’s role in the natural cycles of our planet; its connections to land, food, and energy; and perhaps most importantly, its influence on our cities, our societies, and our cultures. We use this perspective to help our clients implement integrated solutions to solve the most pressing water management challenges.”
What if we showed you how, with a “OneWater” approach, we’re giving communities, industries and regions the resource they need to flourish and grow?
OneWater is an integrated and collaborative approach to understanding and solving complex water challenges — not only those that we face today, but also those we will face tomorrow.
The OneWater landscape includes water sources — for example, streams, rivers, lakes, seas, and oceans — and water users, which includes all of us as well as the flora and fauna that need water to survive. In every location on earth, water cycles endlessly between water sources and users.
At Jacobs, we focus on optimizing the planning, implementation and operations of the complete water cycle, including surface water, groundwater, desalination, stormwater and flood management, conveyance, wastewater, reuse and environmental flows. We also work with clients and communities to identify and show how water challenges are connected across the landscape.
-
All water has value
We look at the water cycle holistically to discover what makes each watershed, each community and each water-related challenge unique.
-
Water challenges are interconnected
We recognize water’s connections to land, food and energy to solve complex water management and community challenges, not only those we face today, but also those we will face tomorrow.
-
Water solutions must be sustainable, inclusive and equitable
We focus on inclusive planning, considering the needs of all those who influence or are influenced by water, and prioritizing solutions that benefit people, the environment and the economy.
How do OneWater approaches benefit your community?
- Engaging the full range of community stakeholders, including customers, businesses and public officials, to find opportunities for successful partnerships and promote social equity.
- Identifying future actions and investments focused on climate adaptation and resilience, including tackling water scarcity and urban flooding with integrated water management practices.
- Incorporating Jacobs’ domain-driven innovation and technology, including Digital OneWater — our integrated ecosystem of data-enabled solutions.
- Prioritizing solutions that promote local workforce development, provide meaningful co-benefits and minimize community impacts.
- Recognizing the circularity of local economies and repurposing traditional waste as a valued resource (such as using biosolids to produce energy, using reclaimed water to augment potable water supplies, or integrating stormwater in functional landscapes.)
- 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 community plans and priorities.

St. Petersburg, Florida
Jacobs worked 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 OneWater, consolidated and integrated approach will result in cost savings from economies of scale as well as regional collaboration opportunities. OneWater 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.

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, OneWater” 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.

How Singapore Turned its Water Woes into a NEWater Model
Water scarcity isn't a new phenomenon; historical records note water shortages dating as far back as the 1800s. And, since there’s no new water on Earth, we’re drinking the same water dinosaurs did. What if we showed you how Jacobs and Singapore’s PUB turned water scarcity into international successes with an innovative water reuse strategy?

Central Interceptor Largest-Ever Wastewater Project
Central Interceptor, the supersized wastewater tunnel, will play a crucial role in ensuring cleaner waterways for central Auckland, New Zealand.
“A OneWater approach opens our teams to view all water as a resource, not as stormwater, wastewater, drinking water or water for industry but as OneWater; 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 OneWater mindset, our teams work to protect and give communities, industries and regions access to the resource they need to flourish and expand.”
