By now, you’ve probably heard of triple bottom line accounting, a full cost accounting approach considering the economic, environmental and social impacts of a decision or more poetically, the three P’s: people, planet and profit. In the stormwater infrastructure planning world, as in many other urban planning arenas, this approach is gaining

 This short video explains how rainwater harvesting is a logical and feasible approach to managing stormwater runoff, citing example usage for a typical commercial office building.Current engineering practice divides management of drinking water, stormwater, and wastewater. A typical commercial office building may average 3.1 million gallons of

This patented technology is employed by the Stormwater Management StormFilter in order to prevent surface blinding, ensure use of all media, and prolong cartridge life. In principal, the system siphons stormwater runoff through its cartridge.First, stormwater enters a StormFilter cartridge, percolates horizontally through the cartridge’s filter

As an industry, we’ve acquired a vast amount of knowledge about stormwater, its adverse impacts, and the best management practices (BMPs) implemented to mitigate them. However, the spirited debate with regard to whether the field or the laboratory is the best arena for evaluating BMP performance refuses to yield to consensus. Here are some of the

Filtration CharacteristicsMedia Surface AreaFiltration flow rates are typically expressed as a surface area specific operating rate such as gallons per minute per square foot (gpm/ft2) of surface area. Lower specific operating rates translate to better performance and longer maintenance cycles. Specific operating rates higher than 2 gpm/ft2 of

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

Stormwater management is a broad topic, significant to us all.   It is important for the environment, there are endless regulations to abide by, an ever-expanding portfolio of products to choose from, budgets to meet and many opinions to consider. This is why we created The Stormwater Blog.At Contech, we have experts who have been in the stormwater

Filtering stormwater is an effective way to remove the most challenging pollutants from urban runoff - including fine solids, soluble heavy metals, and total nutrients. Though the physics of filtration are the same, there are many variables to consider when designing a stormwater filtration system. It’s important when designing a filter treatment

All stormwater BMP’s will require maintenance at some time or time interval. Long-term maintenance costs and maintainability are very important considerations. Here are some other things you should consider when discussing maintenance of your stormwater filtration system.1. Evaluate availability of maintenance contracting. It is the nature of
