PROJECT #1: Reimagining Water Features for Functional Stormwater Management - Introducing VHA Integrated Water Feature Storm System (IWSS)

PROJECT #2: Upcoming and Stay Tuned!

As cities confront the dual challenges of climate-driven stormwater management and responsible water use, traditional approaches increasingly rely on costly, space-intensive underground infrastructure that treats rainwater solely as a regulatory burden. This article introduces the Integrated Water Feature Storm System (IWSS) developed by Vincent Helton & Associates (VHA) — a dual-purpose, above-ground solution that transforms architectural water features into functional stormwater infrastructure.

Building on more than four decades of expertise in mechanical and architectural water systems, IWSS integrates automated controls, stormwater detention, and biofiltration directly into the design of decorative water features. During dry periods, the system operates as a conventional recirculating water feature, delivering aesthetic, acoustic, and microclimate benefits. During wet periods, it seamlessly transitions to capture, detain, and gradually release stormwater in compliance with municipal rainwater management criteria, reducing peak flows and minimizing reliance on underground detention tanks.

Through built and operational projects in Vancouver and the Lower Mainland, IWSS demonstrates how stormwater management and placemaking can coexist and reinforce one another. By reimagining water features as active participants in urban infrastructure, this approach converts regulatory requirements into visible, experiential, and sustainable design assets—setting a new benchmark for climate-resilient urban development.
