We know our audience is well educated about stormwater filtration systems, when regulation calls for them, and how they should be used and installed. But every year at trade shows and lunch and learn presentations, we are surprised to find out how many engineers don’t know about some benefits offered by the Aqua-Filter.
Here are a few to check out.
1. If it’s installed in the USA, it’s built in the USA. That’s right; the Aqua-Filter is built at home, as close to the installation state as possible. This allows us to deliver the product faster and more cost efficiently.
2. Installing the Aqua-Filter doesn’t require a crane. The modular construction and lightweight but durable materials mean skipping the high cost of a crane.
3. As a bonus, the installation doesn’t require special sealants for piping connections.
4. Each unit includes lifting supports and stub-outs for the inlet and outlet piping to allow for quick and simple connections.
5. A dual process, with vortex separation removing larger pollutants prior to the water reaching the filtration chamber, extends the life of the filter media and reduces maintenance requirements.
6. Independent validation should always be considered. Options include the new Total Phosphorus Removal Credit from the Virginia Department of Environmental Quality, along with NJDEP certification and NJCAT verification. The Aqua-Filter has independent field test verification and total Phosphorus Removal Credit from Virginia.
7. What storage is included for sediment? What about oil and debris? This number can help you consider the long-term cost of maintenance. The Aqua-Filter has sediment storage of up to 310 ft3 and oil and debris storage up to 1,900 gallons.
8. The Aqua-Filter works with the only EPA registered filter media for stormwater treatment. PathShield filter media offers a new approach to water treatment by killing bacteria when it comes into contact with filter media granules. The filter media is stable, non-toxic, not consumed, non-corrosive, requires no power source to kill bacteria, and is not affected by temperature changes.
9. The Aqua-Filter can be customized to work with your project. You can start with our project and system design tool at or call us to speak with our experienced, technical team of experts.

When considering a stormwater filtration system, engineers have an array of choices. So, it’s important to first consider these short and long-term outcomes and options when drafting a project’s specifications.
1. What flow rates are available with the system? This can vary widely. At first glance it may appear that the highest flow rate is the best; after all, it can better handle high water rates in storms and floods. However, it’s not that simple, which leads us to the next question.
2. 80 percent removal of what? Too often, stormwater filtration systems are not tested consistently, lacking apples to apples comparisons. This leads to challenges for engineers trying to meet regulations that can differ broadly across the country. The specs may state that a filtration device meets the 80% removal rate, but if lab testing relied on a larger particle size than another system, you might not be getting the whole picture. Make sure you ask about the particle size that was used in the product’s testing to confirm that it meets your desired filtration expectations. Don’t skip out on quality just to achieve a higher flow rate.
3. What field tests were used? Best-case scenario is to select a product that has been tested by a third party, outside the lab under real world conditions. Stormwater runoff contains all sorts of material from tree branches, to sediment to car oil. Product performance can’t truly be measured by lab testing alone.
4. What are the installation requirements? Engineers walk a tightrope while juggling installation timelines, client demands and budgets. Ask early about what equipment will be required for installation, especially if special circumstances exist. Will shipping require road closures? How long until it is ready? What about backfilling?
5. What are the storage capabilities? Compare the sediment storage as well as the oil and debris storage, then consider what this means for maintenance and long-term life of the equipment. Can your client save more over 5 years by investing now?
6. What filter media options are available to my client? Take the time to ask extra questions about the filter media, how easy is it to use, what filter options are available for site-specific contaminants of concern, and how often it requires replacement.
By analyzing the stormwater filtration system up front, engineers can bring added value to their clients by helping address concerns before they happen, and helping achieve progressive stormwater management for the long term.
