  • Our essential guide to the CIRIA 753 SuDS manual for water management

    If you’re a drainage designer in the UK, you probably already know about the CIRIA SuDS manual: To help our customers interpret these guidelines, we’ve created “A Guide to Representing SuDS in InfoDrainage”, which explains all of the settings and options in the software that can help you meet the recommendations of the CIRIA manual.…


  • The role of ponds and infiltration basins in sustainable drainage design

    Ponds and infiltration basins are two of the most effective strategies in sustainable drainage design, offering multiple benefits beyond simple stormwater control. By capturing runoff from impervious surfaces and either storing it for gradual release or allowing it to soak back into the ground, these systems reduce flood risks, improve water quality, and recharge groundwater…

    What are soakaways and how should they be designed?

    Evolving weather patterns and increasing rainfall lead to water and drainage challenges for homes, businesses, and infrastructure. Developers must incorporate drainage systems in their planning that can solve current water challenges and meet tomorrow’s unknown water management needs. Soakaways can create safer, more resilient communities while protecting the environment. What are soakaways? Soakaways reduce the…


  • illustration of sustainable drainage project. The image shows a bioswale, which is a landscaped feature designed to manage stormwater runoff and promote groundwater recharge. The bioswale includes a variety of plants and grasses that help filter pollutants from the water. The area is green and lush, with various types of vegetation interspersed throughout. The ground has a gentle slope directing water flow toward the plants, which aids in natural water purification and absorption. The setting appears to be part of an urban or suburban environment, with some paved surfaces visible nearby.

    Smart City SuDS: How I built a practical toolbox for evaluating bioswales

    We are pleased to spotlight guest author Mariya Bodylevskaya, who discovered InfoDrainage in the course of her studies around sustainable drainage at HFT Stuttgart. She shares her experience building a framework for better understanding and evaluating the performance of bioswales in urban environments. For several years, I have studied the topic of Sustainable Drainage Systems…


  • What is a bioretention system and how does it help control stormwater runoff?

    Bioretention is a stormwater management practice that harnesses natural processes to treat and manage stormwater runoff from impervious surfaces such as rooftops, driveways, and parking lots. If you live in a city, you may have seen many of these types of systems. By utilizing a combination of vegetation, soil, and beneficial microorganisms, bioretention systems capture,…


  • Do you need a Rainwater Management Plan? This Irish manual provides excellent guidance.

    Anthony McCloy is the managing director of McCloy Consulting and regularly speaks at conferences and seminars, provides university lectures, delivers national SuDS training workshops and has recently contributed to Ireland’s Rainwater Management Plans: Guidance for Local Authorities. Does your municipality need an RMP – a Rainwater Management Plan? In the UK, there are lots of…


  • How does cellular storage work for stormwater control?

    Certain stormwater controls are designed in ways that effectively divert water away from a site – but not cellular storage systems. Sometimes also called geocellular systems, geocellular attenuation tanks, or soakaway tanks, these Sustainable Drainage Systems (SuDS – aka LIDs/BMPs/WSUDs) capture stormwater in large underground containers for slow release. But why utilize a stormwater control…


  • The benefits of porous pavement in drainage design

    Sometimes called permeable pavement, porous pavement is an innovative and environmentally friendly approach to managing stormwater runoff in urban areas. As cities have grown, the sheer number of impermeable surfaces like roads, parking lots, and sidewalks has only increased, leaving traditional drainage systems struggling to cope with the volume of runoff. It leads to increased…


  • How do swales work? Understanding what a swale is and how they should be designed.

    Swales are essential components in modern drainage design and play a significant role in managing stormwater runoff, rainwater runoff, and promoting sustainable drainage practices. These shallow, vegetated channels are designed to slow down, capture, and filter stormwater by controlling the flow of water through the swale, reducing the risk of flooding and improving water quality.…


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

    As the world’s drainage challenges grow, designers are constantly looking for new ways to handle stormwater. Commonly known as stormwater controls (SWCs), a subset of sustainable drainage systems, known as SuDS (LIDs/BMPs/WSUDs), have grown popular globally. SuDS work with nature, rather than against, and can be seen as more sustainable means of handling stormwater inflow…
