Drainage Runoff Rates


When embarking on a large construction project, whether building a new housing estate or a multi-story car park, it’s vital that rainwater drainage runoff rates are predicted and accounted for. Here at Express Drainage Solutions, we will consult with your project managers and conduct surveys to establish key crucial information, including: 

  • Assessing your entire site’s predicted runoff rates 
  • Deciding the size of attenuation storage tanks
  • Carrying out the drainage works in line with our surveys 

As leading drainage experts for London and beyond, our consultants will handle drainage needs for the most complex of projects, accurately calculating Greenfield runoff rates to inform our designs, and installing the systems ourselves to ensure quality-assured standards. 

For further information regarding our extensive services, please contact us today. We’ll be glad to discuss your project needs in more detail.
