5D Tech Saves $400 Million in Water Project Breakthrough

Trending Innovators | 8 August 2025

In a milestone for smart infrastructure, the EchoWater Project: one of the largest wastewater treatment efforts in the United States, has saved an estimated $400 million by adopting 5D Building Information Modelling ling (BIM) technology. This innovation not only revolutionised project management but also set a new benchmark for efficiency and sustainability in public works.

The project, led by the Sacramento Regional County Sanitation District (SRCSD), combines advanced modelling, real-time cost forecasting, and water optimisation to overhaul its wastewater treatment facilities. EchoWater aims to improve water quality flowing into the Sacramento River, in line with California’s ambitious environmental standards.

What Is 5D Technology?

5D BIM expands upon traditional 3D modelling by integrating time (4D) and cost (5D) dimensions into the digital planning process. For EchoWater, this meant every component such as pipes, valves, concrete, wiring were digitally modelled with a live connection to scheduling and budget metrics.

This allowed engineers, contractors, and regulators to visualise the entire project lifecycle before breaking ground, minimising risks, rework, and costly delays. The real-time collaboration between various stakeholders significantly streamlined communication and improved decision-making throughout construction.

Results That Matter

• $400 million in cost savings

  
  

• Significantly reduced water waste

  
  

• Accelerated project timelines

  
  

• Improved environmental outcomes

  
  

By shifting from static blueprints to a dynamic digital twin of the treatment plant, the team was able to identify redundant processes, optimise resource allocation, and dramatically lower unforeseen expenses.

Why It Matters

With infrastructure spending under constant scrutiny, the EchoWater case is a compelling proof of concept for government-led digital transformation. It highlights how embracing smart technology can lead to real financial, operational, and environmental gains.

As municipalities across the globe look to modernise ageing water systems, EchoWater may well become the blueprint for a new era in public utility projects, where data, design, and discipline converge.
