  • What is a swale? Definition, purpose, and how it works.

    Swales are a common sustainable drainage feature that provides a simple and effective way to manage stormwater runoff. They are commonly used along roads, parking lots, developments, and other areas where rain falling on hard surfaces needs somewhere to go. A swale is a shallow channel or depression designed to collect, slow, and convey stormwater…

  • How does InfoDrainage compare to HydroCAD, TR-20 & TR-55?

    In stormwater management and drainage design, selecting the right software is not just about features. It’s about how well a tool fits the way engineers actually work. Tools like HydroCAD, TR-20, and TR-55 have long been used for runoff calculations based on established hydrology methods. At the same time, newer tools like InfoDrainage are expanding…

  • What is an infiltration trench and how does it work?

    Infiltration trenches are a common feature of Sustainable Drainage Systems (SuDS) and are widely used in urban drainage design to manage stormwater and rainwater runoff, as well as promote sustainable drainage practices. As the world’s drainage challenges grow, designers are constantly looking for new ways to handle stormwater. Commonly known as stormwater controls (SWCs), a…

  • How ISG got their InfoWorks ICM software models FEMA approved

    The City of Brookings in South Dakota, like many other inland US cities, is struggling with increased amounts and instances of flooding. They enlisted ISG, a nationally recognized, 100% employee-owned, multi-disciplinary architecture, engineering, environmental, and planning firm to help them update the city’s master drainage plan, which hadn’t been revised in 15 years. ISG’s Jacob…

  • The path to digital transformation in water infrastructure is becoming more clear

    The water industry is undergoing a state of rapid change, which will only speed up as the climate shifts. GHD research estimates that droughts, floods and storms could wipe $5.6 trillion from the GDP of world’s top economies by 2050. Are we prepared as an industry for the challenges that are unfolding? Way back in…

  • AMP8 opportunities: Biodiversity Net Gain requirements will give SuDS a big boost

    One of the most important things UK water regulator Ofwat wants to see water companies use AMP8 funding to achieve is elevating the importance of Biodiversity Net Gain (BNG). We wrote about it in our latest white paper ‘AMP8’s unprecedented opportunities’, part of which we’re excerpting here. A change that makes society better is one…

  • AMP8 opportunities: Solving the UK’s CSO problems with hydraulic modelling

    The recent AMP8 funding cycle is perhaps the best chance for water providers to secure funding for changing the way they monitor and solve for CSOs. We’ve written about it in our new white paper, AMP8’s unprecedented opportunities, a portion of which we’re excerpting here on the One Water Blog. How software can help manage…

  • Harnessing the power of InfoDrainage in Canada: regional and customizable settings

    As urban areas continue to expand and our drainage infrastructure continues to be pushed to the limits, managing stormwater and urban drainage with old methods has become untenable. This isn’t just a regional problem, but a global one. Our teams often get asked, “Does InfoDrainage work in my country/region?” Generally speaking, the answer is going…
