Managing water resources efficiently is critical for towns, cities and communities all over New Zealand.

WSP plays a key role in supporting those who manage water supply and treatment plants, to manage them effectively for the benefit of everyone who depends on them.

Many of our water asset management projects have been recognised nationally and internationally. We have presented papers at conferences in New Zealand and overseas, and various publications and manuals have featured our work as case studies.

We are committed to the industry and have built an excellent reputation. We are active promoters of best practice in the water management sector and sit on industry boards and forums, and have a strong profile at water resource management conferences.

Our experience in New Zealand

We offer a full range of disciplines to support water asset management, including:

  • 30–year planning – and consultation for infrastructure assets
  • Policy advice – rationalisation of business structures, district and regional plan input, and structure plan input.
  • Levels of service – setting and monitoring KPIs, benchmarking and gap analysis.
  • Compliance - programming, monitoring drinking, waste and stormwater, reporting.
  • Non asset solutions – demand management and forecasting, leak detection, inflow and infiltration, water conservation and reuse.
  • Asset and operational performance – treatment plant performance, maintenance planning, skill gap assessment, manuals and SOPs.
  • Resilience planning and emergency preparedness – CCTV, condition assessment, testing, reporting and management, extending asset life, pipe refurbishment, pressure management.
  • Financial – valuation, tariffs, development contributions, programming and funding.
  • Asset data – asset management systems, data management system operation, GIS.
  • Procurement – procurement strategies and contracts, contractor and supplier management, performance contracts, customer service reviews, establishing customer care, and subsidy applications.
  • Modelling – water, wastewater and stormwater.
  • Documents – asset and activity plans, standards, codes and specifications.
  • Environmental management – biosolids and sludge management, trade waste management and bylaws, carbon and water footprints.



How WSP Helps Clients Tackle Asset Management Challenges for the Water Industry

WSP draws on decades of experience, with core elements of our successful implementation of asset management plans and programs including helping clients to build strategic foundations, to establish service levels and performance baselines, and to develop realistic and integrated capital and financial plans.

Our expert team includes authors of and key contributors to international guidelines and best practice development, including the International Standard for Asset Management Systems and ISO 55001: 2014. Given the multiple services available within our asset management program, WSP is well positioned to address specific pain points in water, wastewater and stormwater system management. We can help clients capture and analyze data about the assets themselves—their condition, location and real value—and help them make smarter, more cost-effective decisions to better understand their largest risks and avoid critical failures within their water infrastructure.

WSP’s comprehensive know-how within the water, wastewater and storm water sectors gives us unrivalled forecasting abilities that help optimize investment, bring cost and service level benefits, and maximize asset longevity and value. We have led implementations around the world, and have developed roadmaps on how to improve the asset management of water and wastewater systems through changing processes, developing staff and investing in technology.

For Northern Ireland Water (NI Water), a state-owned provider of water and sewerage services in North Ireland, we developed a robust risk and consequence model to target, prioritize and increase the timing and efficiency of capital maintenance interventions in the trunk main network.

We assessed financial, hydraulic, water quality, environmental and social criteria to develop statistical frequency-of-failure models, and derived an overall consequence score. Intervention works were subsequently prioritized and justified for the 3,000 km trunk and strategic water main network based on likelihood and severity of failure. The model gives NI Water unprecedented visibility of the mains most in need of intervention/mitigation and improves the risk management and resilience of the system.

In another instance, WSP assisted VA SYD, an umbrella organization formed by four municipalities in southern Sweden serving 400,000 inhabitants. Swedish municipalities are responsible for supplying populations with water and wastewater services. Sweden’s water tariff structure focuses on central tenets such as fairness and prime cost principle, where benefactors of water and wastewater services should pay no more than what is fair and equitable, and the gross revenue derived from tariffs should not exceed the utility’s total expenditure. As member municipalities differ greatly in population, rate of urbanization, density and water situation, as well as in tariff structures and water rates, WSP acted as a process leader, helping VA SYD unify its structures to best meet the overarching goal of fairness and equitability while still following the prime cost principle in each municipality.

In Australia, WSP was commissioned by Sydney Water Corporation (SWC) as one of three suppliers to assess the condition of its critical water main and sewer rising main assets. The total program of works was initially planned to be delivered by June 2016, with around 350 km of pipeline inspections. The program was extended to June 2017 and included more pipelines for inspection. The Pipeline Condition Assessment Program will provide SWC with information that will allow them to better manage their infrastructure in the future.

For South West Water, a provider of water and sewerage in the UK, WSP helped develop a vision, policy and asset strategy for best practice asset management and a roadmap on its implementation. WSP rewrote the existing draft asset management policy in alignment with the corporate vision and policies that were identified. Our team then facilitated workshops to identify the stakeholders affected by the asset management process and goals, and to generate components that made up “good asset management.”

The results of the workshop were used to refine the asset management policies and write a set of asset management strategies. The tasks to implement the strategy were further developed into a detailed three-year program of improvements that would lead to achievement of the vision and strategy.
