Why LID / Green Stormwater Infrastructure?

In 2005, while most of the development and engineering community in Houston Texas had their doubts, Convergent Water Technologies set out to prove that Low Impact Development could do for the community what no other stormwater management approach could; reduce flood risk, improve stormwater quality and lower overall cost of development.  Since then, we have traveled the country teaching others the discoveries and lesson’s we have learned along the way, pushing forward a new style of Low Impact Development that focuses on high performing, multifunctional systems as opposed to unproven prescriptive design.  We call this Multifunctional Stormwater Design.

While developing Multifunctional Stormwater Design with our partners and early adopters, we used developers and municipalities as our guiding light, or North Star, in our pursuit, knowing that in order to get their full buy-in, we would need to understand what was most important to them. So, why would a developer or municipality ever want to use Multifunctional Stormwater Design?

  • Lower Upfront Construction Cost
  • Increased Lot Yield
  • Lower Long-Term Maintenance Costs
  • No Design / Construction Delays

While the rest of the country was focused on water quality, we were focused on water management.  While the rest of the country focused on treating one inch of rainfall, we were pushing the limits and learning how to manage the largest storms.  We believed that if we could make Multifunctional Stormwater Design work in a place like Houston Texas, we could make it work anywhere.  Why?

  • Clay Soils = Very Little Infiltration
  • Shallow Outfalls = Many Roadside Ditches
  • Intense Rains = 2016 Tax Day Flood 16 inches in 12 Hours
  • Extended Rains = 2017 Hurricane Harvey 40”+ in 60 hours
  • High Annual Average Rainfall = 54” Annually
  • Flat Coastal Prairie
  • Could there be a better place to prove LID Works?

Since 2005, the team at Convergent Water Technologies and it’s partners around the country have dedicated their work to both the big discoveries and the small, that have drastically improved the performance and reliability of Low Impact Development.  Collectively, they have been compiled here on this site, so that you may take advantage of the knowledge that has come from our success as failures.
