Three Components of Infiltration System DesignCommon infiltration practices include drywells, bioretention, permeable pavement, infiltration trenches, infiltration basins, and subsurface infiltration galleries. Regardless of their form, all infiltration systems have three primary components: storage, treatment, and infiltration.1. StorageRetention

It’s that time of year again - temperatures have dropped below freezing, and the wintery weather has blown in. Departments of Transportation, state, local and city road crews are being kept on their toes, applying roadway treatments and safe passage for all of us. It is estimated that the US spends approximately $2.3 billion annually to keep highways free of snow and ice, and roughly 20% of transportation department budgets goes toward winter road maintenance.

Factors Impacting Rainwater Harvesting ROI When you mention a commercial rainwater harvesting system (RWH) to an engineer, developer or owner, one of the first questions you get is “what’s the ROI?” Return on Investment and Net Present Value vary widely depending on specific project variables and there is no one correct answer.  The three largest

Historically, underground infiltration beds have been laid out in either square or rectangular shapes, sometimes far away from where the actual rain drops fall. These large systems are typically fed by a series of upstream catch basins and conveyance pipes. Several factors contribute to site layout, but mostly it simplifies the hydrologic and

The Low Impact Development (LID) approach to site development and stormwater management is rapidly becoming the required design approach in many areas of the United States.The basic principle is to use nature as a model and manage rainfall at the source. This is accomplished through sequenced implementation of runoff prevention strategies, runoff

An increasing challenge that we see with our customers is balancing water quality with water quantity. Conventional design would be to use an in ground detention pond. But, if this is not an option, whether the owner does not want the aesthetics of a pond, the land needs to be used for parking, or you have a layer of clay soil that makes

If more than one type of infiltration system meets your project requirements, your decision may be cost driven. It’s important to maximize the storage efficiency in the available space at the lowest possible cost.Underground, Open-Bottomed Chambers This example highlights the need to evaluate multiple options and configurations to find the most

1. IrrigationIrrigation is the most common application for harvested water. Treatment requirements are lower, which makes the harvesting system simpler, and the demand can quickly drain the cistern to make room for the next storm event. However, relying solely on irrigation for net-annual runoff reduction is rarely enough. In most locations, there

Water is necessary for economic growth, a healthy environment and vibrant communities for future generations. With gridlock in Washington and broken budgets at all levels of government, it may not seem like the right time to make broad changes in water management policy. But change is happening and the catalyst for that change is stormwater
