Trash control - an $11.5 billion dollar problem and a major contaminant for stormwater

Stormwater contaminants are, for the most part, usually the same. The issues that we typically see in our business center on: heavy metals, hydrocarbons, phosphorous, and sediment loading. Another MAJOR issue our clients have is TRASH CONTROL.

It might not be an issue that you have thought about, but I spent some time this afternoon looking to see if anyone had calculated the amount of trash and debris that finds its way into Long Island Sound. While I didn't find information specifically targeted for Long Island Sound, I did find a nation-wide study funded by the non-profit organization, Keep America Beautiful, detailing the volume of trash/litter found in the US, the toll it takes on the American economy and behaviors that contribute to littering. The results of their survey were released on December 3, 2009.

Some shocking key findings from their report:

Litter conservatively costs our nation $11.5 billion per year. These are direct costs, including cleanup and prevention programs, and are carried largely by businesses and taxpayers. Not included in this figure are significant indirect costs:

• Decreased property values. 93% of homeowners, 55% of real estate agents and 90% of property appraisers surveyed stated that a littered neighborhood would decrease their assessment of a home’s value
• "Opportunity Costs” such as decreased commerce and tourism in blighted areas
• Health effects and related costs of littered environments

The study concludes that at least 51.2 billion pieces of litter are left on roadways in the U.S.; an average of 6,729 pieces of litter per mile.

Cigarette butts comprise 38% of all items littered on the highways, streets, parks and playgrounds (in urban, suburban and rural areas of America).

The Keep America Beautiful Report detailed littering behaviors, identified factors that encouraged littering and made suggestions on how to reduce litter. I think it is an important report and encourage you to read their findings in full. For executive summary and full report, click here.

More on trash control tomorrow.

Easy retrofit solution for stormwater systems and trash control

One of our municipal clients here in CT contacted us one day because he was often called by a local resident with complaints about trash, bottles, cans and other debris which had been thrown out car windows and would travel through the storm water system and end up in this resident's wetlands/backyard. The area is more of a suburban almost rural area, so you can imagine that all of this trash was even more visible and a real eyesore to anyone driving by. The resident was just plain tired of cleaning up after everyone else and the town needed a long term solution, extremely low maintenance solution to correct the problem. What could we suggest?

After a quick survey of the area, we saw the offending storm structure and realized the best alternative in this case would be our self-cleaning, stainless steel, wedgewire screen and orifice place.

If you are not familiar with wedgewire screens, they are very cool and have a wide range of applications - not only as trash and debris screens at hydro plants around the world, but also as fish exclusion in ponds/streams and another common use is in detention ponds to prevent trash/debris and small animals from getting into the system.

In this case, sediment, trash and debris would be prevented from entering the system, yet water could still flow through the system at high flow rates. It was an easy fix for this problem and the complaints stopped!

The top picture shows the screen after the first major rain storm. You can see the leaves stuck to the screen. When the system dries out, the leaves will fall off. The system is constantly working.

The picture of the red grate is the top of the structure and if the water gets high enough, it will flow into the system this way.

Our screens are highly engineered and designed for site specific applications.

Stormwater vault installation to improve storm water runoff that goes into Long Island Sound

We had our second installation of the TerreKleen Water Quality Treatment Vault get installed in Stamford this week.

The TerreKleen is unique in that this hydrodynamic separator utilizes stacked inclined plates to assist sediment to fall out. The first chamber is designed to capture large sediment, trash/debris, and contain oil. The second chamber contains stacked inclined plates. Stacked inclined plates have been widely used in the drinking water industry for the past 80 years. This technology has been adapted to the storm water industry.

The installation went smoothly and quickly. Here are a few pics...

This picture shows the hole where it will be installed. The markings show the positioning where the unit will go.



TerreKleen is made of 3 pieces. The TerreKleen is assembled in-place as each piece stacks on top of each other.

In this picture, you see the "working section" of the TerreKleen hoisted off the flat bed truck with a crane. The first section of the installation is getting positioned over the hole and being aligned for installation.

The site is being re-developed. The building behind will be re-furbished.

The second section, the riser, has been lifted off the tractor trailer and is getting positioned into place. It will install directly on top of the first section. Each of the three sections are designed to "interlock" together.

The lines attached to the crane's lifting chains assist in the alignment.






The riser section installs very quickly right on top of the working part of the TerreKleen.

TerreKleen can be easily sized for any size project. The installation is the same for any unit. While this picture shows the smallest TerreKleen unit (approx. 4'W X 6'L in size), available, TerreKleen is easily sized for any size project. No matter the size of the project, the TerreKleen takes advantage of the efficiency of the stacked inclined plates to maximize sedimentation surface area in the smallest unit footprint.

One more piece and the installation will be done.






Better not blink, the top is quickly installed!

This client requested manhole covers for the top. Other clients prefer manhole grates.










Installation complete and lifting rings are removed. Contractor will connect all of the inlet and outlet pipes and backfill around the unit. Then, unit is ready to work.

If you have any questions about this installation or any of the other storm water products in our line, give us a call. Click here to get to our website.

Cleaner storm water in 45 minutes! (The quick and easy installation of a hydrodynamic separator)

Our first hydrodynamic separator (water quality treatment vault) was installed yesterday in Stamford, CT. This separator will capture trash, sediment, debris and also contain oil.
The TerreKleen is a modular system that installs in about 45 minutes. Here are some pictures showing the installation.

The unit arrived on site via flatbed truck at about 8AM. The crane arrived shortly after. Setting up the crane and final site preparations took about an hour. Around 9AM, the crew started to prepare the unit for installation by attaching these hooks to the TerreKleen. They used these hooks to secure the first section.














The crew wants to get this unit installed as quickly as possible. The installation site is in a tidal area and the tide is starting to come in. The crane operator lifts the TerreKleen off the truck and moves it toward the hole where it is getting installed. The ropes will assist in guiding the unit.

The working part of the TerreKleen is successfully installed. As you can see, the TerreKleen is a two chamber system.
The first chamber (near side) is designed to capture: sediment, trash, debris and will contain oil.
The second chamber (far side) houses the stacked inclined plates. Stacked inclined plates have been widely used in the potable drinking water industry for the past 80 years. Their use give the TerreKleen the largest sedimentation surface area in the smallest area footprint. Once sediment is captured in the second chamber, they will not re-suspend regardless of flow rate.



















In a few minutes, the riser is installed and we can move on to the final piece.















A few more minutes and the top is positioned for installation.














45 minutes later.....TerreKleen hydrodynamic separator installation is complete! All that is left now is to hook up the pipes and back fill around the unit.

More projects are planned. We will keep you posted.
