Specialists across the water cycle - From source to tap

Our water specialists provide collaborative design and advisory services for wastewater, storm water and water treatment projects for urban and rural environments. With water scarcity an ever-present consideration, our project teams strive for the efficient use of natural resources and sustainable solutions.

Cherishing water so that our people, communities and environment continue to flourish. Water is the world’s most precious resource. The world’s water is coming under increasing pressure due to rapid urbanisation, food production challenges, aging infrastructure and climate change. WSP Opus’ specialists facilitate management of the entire water lifecycle from source to tap and return to the environment. We provide services for water and wastewater conveyance and treatment, water resources and flood risk management, water for agriculture, water asset management and for hydropower generation.

Our services are Future Ready. Our services enable communities and businesses to use water in ways that balance social, economic, environmental and cultural considerations to protect our natural water environments and water resources. We challenge the status quo to deliver infrastructure that is ready for the changes and challenges that our world faces now and into the future. Enhancing the environment and ensuring safe, productive water for future generations.

Our client centric approach considers the full asset lifecycle from front-end planning, environmental assessment, design, operation through to renewal to drive outcomes for our clients, their customers and communities. WSP’s global reach allows us to draw on international water experts across New Zealand, Australia, the Americas and Europe to bring different ideas to our clients and to develop innovative solutions.


We understand water, we design the infrastructure to access and use it and we train our clients in how to use and optimise our solutions.   

Our suite of services includes asset design to implementation, and ongoing management for both urban and rural storm water, wastewater and water supply projects.


Our team has forged a global reputation for smart and sustainable water supply, treatment and asset management.

We draw knowledge and resources from our global team to provide creative water management solutions. Our team collaborates to deliver effective cost savings, longer facility life and more efficient service.

We can help your organisation or business to use precious water resources efficiently, through demand planning and forecasting, system design and operational planning. Our work in the water sector has three key areas: water asset management, urban water, and productive water. 

Water asset management is about ensuring a sustainable supply of clean water and associated services. Unexpected costs, poor performance and inequitable burdens on future generations can be prevented if asset management planning is given the same priority as initial capital investment. This is our forte. We provide advanced asset management tools and deep analysis for all parts of the water asset cycle. We have a number of highly skilled engineers, environmental scientists and other specialist staff working in the water sector, to help with concept design, contract administration, construction supervision and on-site commissioning.

Urban water expertise encapsulates process engineering for water treatment and wastewater treatment plants; pipes, pumps and tanks that deliver water to our towns and cities; and urban stormwater and drainage. We have a long history of designing stormwater systems for municipal and highway environments, and catchment management plans that make sure urban drainage works as it should.

Our productive water capabilities encompass irrigation, water resource sciences, flood management and hydraulic engineering associated with river catchments, coastal environs and hydropower facilities.
