Stormwater Industry Leading Downspout Filtration from CleanWay

Downspout-building2mb.jpg

If There’s a Mysterious Gap in Your Stormwater Best Management Practices (BMPs): LOOK UP!

When we think of stormwater runoff, we most often look down. That’s where the water is, coursing over paved hardscapes and into inlets, basins and non-specific channeled conveyances. Stormwater is a surface contamination issue, first underfoot and then underground. Right?

Rooftops: A Significant, and Often Overlooked, Source of Stormwater Pollutants and Heavy Metals Runoff

Rooftops often represent a large percentage of an industrial site’s hardscape footprint, as much as 25% or more. They’re also collectors and incubators of a wide range of pollutants and dissolved heavy metals that can impact post-construction stormwater Best Management Practices (BMPs) and National Pollutant Discharge Elimination System (NPDES) industrial and non-industrial permit requirements. It’s not just the dissolved zinc from galvanized rooftop HVAC equipment, moss inhibitors and abrasion resistance coatings that pose a challenge. It’s also environmental deposition of dissolved copper and lead from neighboring properties or nearby roadways where copper is found in brake linings and lead is found in tire weights. When you consider the collection of organic matter, including dead birds, squirrels and insects, a rooftop is often an incubator for viruses and pathogenic bacteria that attach themselves to suspended solids resulting in toxic turbidity.

“Our downspout filtration system is just one of the creative ways we help our industrial and commercial partners meet the challenges of stormwater filtration. In fact, it’s part of a whole suite of stromwater filtration products that we’ve created, patented and are able to adapte for each customers specific needs.”

High Capacity, Dry/Wet Configuration and Verifiable Performance

CleanWay recognized the need for rooftop stormwater and downspout filtration over 20 years ago. As a result, we’ve continuously refined our downspout filtration system (also referred to as roof drain filters, gutter drain filters or rainwater filters) to meet the evolving needs of our customers. Unlike inline options, which require cutting and fitting of the existing downspout, our units are free standing, easily accessible for maintenance and cleaning and incorporate a patented water sampling port for verifiable filtration performance. Two levels of outlet openings allow the unit to be run in either a dry (where vector control is a concern) or wet configuration (to increase removal rates with additional contact time).

“All Surface Filtration”, Maximum Volume and Dual Filtration Sets CleanWay Apart

When you’re investigating a downspout filtration system, consider that our filtration vessel is six (6) to eight (8) times larger in volume than inline systems. Then take into account that our rigid strainer is completely covered by a site-specific absorption media envelop to maximize contact with stormwater runoff — virtually eliminating unfiltered water in high volume bypass scenarios: Here’s how it works: Our absorption media section incorporates a flexible open mesh fabric envelope with a specialized media blend suspended from the support assembly and fitted into the basin so all influent passes through both strainer and filtration media before exiting to the downstream conduit. The combination of gross solids removal via the strainer and the absorption / filtration in the media section virtually eliminates heavy metals, suspended solids, turbidity and other pollutants. Our site-specific filtration elements include:

  1. Rigid Strainer: Trash & Debris (sized to capture particles down to 3.2 mm)
  2. Geotextile Element: Sediment & TSS
  3. Adsorb-It Element: Oil & Hydrocarbons
  4. Vermiculite Media: Dissolved Zinc Only
  5. MetalZorb Media: Dissolved Heavy Metals

“We named our company advisedly; CleanWay Environmental Partners is all about the partnership between the industrial site permit holder, their engineering firm or specifier and CleanWay Environmental. We offer our clients a deep reservoir of applied technology across a wide spectrum of water treatment solutions. If you have a unique water treatment of filtration challenge, we invite your inquiry.”

Steve McInnis, President, CleanWay Environmental Partners

Ease of Installation, Configuration, Maintenance & Testing

Our attractive, non-obtrusive downspout filtration systems are easy to install, simply place it next to your downspout and “plug it in.” Available in standard or custom configurations, our downspout filters fit the side of any building, and can be connected on the right or left side, depending on your site configuration. Because rooftop runoff can contain many different pollutants of concern, we help you to determine the best media blend for your application. For ease of cleaning and filter replacement, the top lid can be locked in an open position so a single operator can service the unit by hand or by Vactor truck. Applications include:

  1. Industrial roofs (including permitted Industrial Users (IU), Significant Industrial Users (SIU), Categorical Industrial Users (CIU)
  2. Commercial roofs
  3. High rise buildings
  4. Parking structures
  5. Mixed use buildings

When the City of Riverside, CA searched for solutions to meet California’s Trash Amendments* for stormwater, they approached CleanWay Environmental Partners to conduct a pilot program for Full Capture Trash Treatment Control Devices. We were singled out based on our long experience and strong reputation nationally for solving stormwater filtration, metals removal and wastewater treatment challenges.

Innovative, Modular Curb Inlet & Drop Inlet Filtration Systems

Our partnership with the City of Riverside specifically addressed the development of innovative, modular Curb Inlet and Drop Inlet Filtration Systems. To meet the rigid California standards, our systems are scalable to meet peak flowrates regardless of inlet size; trap all particles down to the 5mm level; does not bypass trash and eliminates upstream diversion. Unlike other systems, the CleanWay solution maximizes catch basin drainage, depriving mosquitoes of breeding habitat, a critical criteria for certification.

“We strive always to design and manufacture products that are useful, practical and deliver long-lasting utility. It’s been our great privilege to work with the Riverside team, and to join the exclusive list of manufactures with products that meet the rigid California Trash Amendments standards.”
Bridget Garlinghouse, EIT, CleanWay Environmental Partners

Maximum Capacity, Modular & Scalable by Design

The CleanWay systems address several key design considerations: The filtration units perform in heavy commercial and residential use urban environments with high trash volumes and under historically high storm flow rates; they fit curb inlets ranging from 10’ to 30’ in length; and the filtration basins are scalable to manage varying volumes at each existing inlet structure.

Unique Challenges Met & Expectations Exceeded

Significantly, the CleanWay system is comprised entirely of perforated stainless steel that folds flat to fit into the narrow inlet opening — then unfolds inside the existing basin structure to occupy virtually the entire existing catch basin volume. The structural rigidity of our system maintains trash catch basin volume under maximum trash/water loading, unlike flexible mesh systems and other inferior alternatives. An integrated, under curb rail system allows the stainless catch baskets to slide out of the way for access to the existing inlet and basin structure and associated piping for ease of maintenance and repair. Our fold flat design also reduces shipping costs, and resolves storage and delivery-to-site issues.

"This was a perfect opportunity for us to apply the knowledge, problem solving ability and fabrication expertise we've applied to similar non-point pollution and stormwater trash abatement challenges in the Pacific Northwest and beyond for over 20 years. Every project is a chance to innovate and refine our products in collaboration with our municipal, state, industrial and commercial partners, and the Riverside project was an exemplary case in point."

*In 2015, the State Water Board adopted an Amendment to the Water Quality Control Plan for Ocean Waters of California (Ocean Plan) to Control Trash and Part 1 Trash Provision of the Water Quality Control Plan for Inland Surface Waters, Enclosed Bays, and Estuaries (ISWEBE Plan). Together, they are collectively referred to as 'the Trash Amendments'. The project objective for the Trash Amendments is to provide statewide consistency for the Water Boards' regulatory approach to protect aquatic life and public health, and to reduce environmental issues associated with trash in state waters.

How Do Catch Basin Filters and Inserts Work?

CleanWay CatchBasinInsert.JPG

As part of a storm drain system, catch basins—as well as catch basin insertsand filters—prevent the accumulation of standing water and flooding. These features prevent water from pooling on roadways, fields, parking lots, or other surfaces. They also can be used to remove contaminants from stormwater runoff, keeping water sources clean. Below are some things you should know about these systems. 

How Does a Catch Basin Work?

When constructing drainage systems, catch basins must be installed properly to function well. The grate should be even with the surface of the ground and connect to a belowground compartment. Stormwater will run into the compartment below and through the outlet pipe that drains the water.

The number of storm drains, required for efficient drainage depends on how much water can be expected during peak periods. For instance, in areas where snowmelt creates a high amount of water, more basins will be necessary. The slope of the ground and the average amount of rainfall will also affect this number.

What Are Catch Basin Inserts & Filters?

Catch basin inserts are used to capture and retain stormwater pollutants. The inserts use a strainer and catch basin filters to remove debris, including heavy metals, sediments, and trash. This pre-treatment removes contaminants from storm water runoff, meeting environmental standards. They can be inserted retroactively or during initial construction of the system, offering a solution to problems that may otherwise pollute water sources and make your company fail water quality standards. 

If your business or municipality requires these stormwater treatment systems, reach out to CleanWay Environmental Partners in Portland, Oregon. For more than 20 years, we’ve been helping businesses across the nation comply with water quality regulations. Our team of professionals will even show you how to maintain and care for your catch basin inserts and filters.

5 Ways Heavy Metals and Chemicals can Contaminate Stormwater Runoff

DSC_0897.JPG

As rainwater travels down roofs and roads, stormwater runoff mixes with pollutants found on artificial surfaces before flowing into basins, rivers, and lakes. Capable of contaminating drinking water, killing marine life, and destroying natural habitats, stormwater runoff needs to be dealt with properly. With pollution problems on the rise, now is the optimal time for property owners and corporations to prevent pollution through responsible stormwater management. Learn about common sources of contamination below. 

5 Things That Can Pollute Stormwater Runoff

1. Auto Emissions

Car emissions are one of the most common causes of stormwater runoff contamination. For instance, when a leaking car discharges oil onto the street, this fluid can seep into soil or get washed down storm drains. As a result, auto emissions can introduce petrol, diesel, nitrogen, and other toxins into water sources.

2. Rooftop Runoff

When it rains, precipitation flows off of roofs and onto the ground. As water drips down these surfaces, it mingles with aluminum, alloys, and other rooftop sediments. Hazards occur when this tainted stormwater runoff affects the soil and surrounding vegetation.  

3. Septic Systems

When septic systems are not routinely pumped, sewage can build up inside of their pipes. Over time, the pressure caused by this congestion can force waste out of the plumbing and into the streets. This sewage carries bacteria that can seep into nearby bodies of water.

4. Pesticides

Stormwater runoff can also carry herbicides, fertilizers, and pesticides. Although these chemicals are safe for field applications, if they are introduced into new environments by rainwater, they can cause issues for vegetation and animal life. 

5. Waste Disposal

The improper disposal of waste can contaminate stormwater. Rather than recycling, some construction company trucks will discard wood, metals, and other materials down storm drains. Consequently, stormwater runoff can carry trash and debris directly into the ocean.

How Heavy Metals Extraction Solutions Eliminate Zinc From Stormwater

Chemical factory

State and local regulatory agencies require industrial facilities to control the runoff of harmful pollutants from their sites, including lead, mercury, and zinc. While eliminating sources of contamination is ideal, this can be nearly impossible on some industrial sites, which is why stormwater runoff filtration is so important. CleanWay Environmental Partners in Portland, OR, specializes in effective heavy metal extraction products proven to eliminate zinc, which can be especially difficult to remove

Why Zinc Is Difficult to Eliminate

Unlike mercury and other heavy metals, zinc can originate from a wide variety of sources. Galvanized metal coatings on metal roofs and fences, for example, will deteriorate over time, releasing dissolved zinc into stormwater runoff. Forklift tires and evaporated motor oil are also common sources of zinc, so your facility may be exceeding environmental regulations even if you don’t use heavy metals in your manufacturing processes. The number of potential sources makes zinc especially difficult to contain, so heavy metal extraction at the drainage system entry point is often the best approach.

The Dangers of Heavy Metal Contamination

When water is contaminated with heavy metals, it becomes a danger to both the environment and human health. It’s important to take steps to ensure the safety of your company’s runoff water so that you meet environmental code. With MetalZorb, an absorbent filtration medium, heavy metals in runoff water are targeted and removed. CleanWay Environmental Partners, Inc. of Portland, OR offers filtration products that meet EPA and NPDES regulations for removing pollutants from urban and industrial stormwater. Below, our experts share some things you should know about controlling heavy metals. 

What Are Heavy Metals?

Heavy metals are a common byproduct of many industrial activities. While some metals are necessary for a healthy life, such as iron and zinc, others can be dangerous, particularly if someone is frequently exposed to them. Dangerous heavy metals include mercury, arsenic, cadmium, beryllium, lead, and hexavalent chromium. Lesser exposure for civilians can occur through water, food, and air. Industries that use or produce these metals are more likely to create risk through stormwater runoff.

Stormwater pollution occurs when debris, chemicals, sediment or other pollutants from urban areas and construction sites get washed into storm drains and flows directly into water bodies. Uncontrolled stormwater discharges containing heavy metals from factories can pose significant threats to public health and the environment.

Why Are Heavy Metals Dangerous?

Long-term exposure to low levels of heavy metals can occur in industrial workplaces. This exposure sometimes leads to chronic heavy metal poisoning, which is difficult to treat when identified. Symptoms such as headaches, muscle, and joint pains, and weakness can occur. Too much contact with heavy metals can be detrimental to human health, and in some cases lead to death.

Additionally, The Clean Water Act requires that industrial facilities, construction sites, and municipal separate storm sewer systems have measures in place to prevent stormwater from being discharged with heavy metals into nearby waterways. Violation of EPA regulations can lead to very costly legal fees and fines.
