NASA Space Shuttle launch - Friday, July 8th!

2011-07-07T00:59:00.001-04:00

I was really excited to hear from a high school friend of mine today advising me that she had been selected and awarded one of 150 tickets to attend the NASA space shuttle launch that is scheduled for Friday, July 8th (Sat or Sun if the weather is bad).

My friend, a Connecticut teacher, is very enthusiastic, a great role model and motivator for any student. She will be given a "behind the scenes" tour of NASA tomorrow and will be observing the launch on Friday -3 miles from the launch pad (where the count-down clock is located). She is documenting her tour and the launch on her blog. The whole thing is very exciting! Here is the link to her blog: http://www.researchameleon.com/

Check it out!!!

US Government releases report detailing climate change impacts on water resources

2011-04-27T08:12:00.001-04:00

WASHINGTON, D.C. – Secretary of the Interior Ken Salazar today released a report that assesses climate change risks and how these risks could impact water operations, hydropower, flood control, and fish and wildlife in the western United States. The report to Congress, prepared by Interior’s Bureau of Reclamation, represents the first consistent and coordinated assessment of risks to future water supplies across eight major Reclamation river basins, including the Colorado, Rio Grande and Missouri river basins.
“Water is the lifeblood of our communities, rural and urban economies, and our environment,” said Secretary Salazar, “and small changes in water supplies or the timing of precipitation can have a big impact on all of us. This report provides the foundation for understanding the long-term impacts of climate change on Western water supplies and will help us identify and implement appropriate mitigation and adaptation strategies for sustainable water resource management.”
The report, which responds to requirements under the SECURE Water Act of 2009, shows several increased risks to western United States water resources during the 21st century. Specific projections include:

a temperature increase of 5-7 degrees Fahrenheit;

a precipitation increase over the northwestern and north-central portions of the western United States and a decrease over the southwestern and south-central areas;

a decrease for almost all of the April 1st snowpack, a standard benchmark measurement used to project river basin runoff; and

an 8 to 20 percent decrease in average annual stream flow in several river basins, including the Colorado, the Rio Grande, and the San Joaquin.

The report notes that projected changes in temperature and precipitation are likely to impact the timing and quantity of stream flows in all western basins, which could impact water available to farms and cities, hydropower generation, fish and wildlife, and other uses such as recreation.
"Impacts to water are on the leading edge of global climate change, and these changes pose a significant challenge and risk to adequate water supplies, which are critical for the health, economy, and ecology of the United States," added Reclamation Commissioner Mike Connor.Reclamation is already working with stakeholders across the West to achieve a sustainable water strategy to meet our nation's water needs. Through the WaterSMART Basin Studies Program, Reclamation is developing and evaluating options for meeting future water demands in river basins where water supply and demand imbalances exist or are projected.

Reclamation is also continuing to implement actions to mitigate and adapt to changing climate. For example, at Hoover Dam, new wide head range turbines are being installed that will allow more efficient power generation over a wider range of lake levels than existing turbines. In addition, through the WaterSMART program, Reclamation continues to work with water users across the West to implement conservation and recycling measures and promote the efficient use of finite water resources. The Department of the Interior has also established Landscape Conservation Cooperatives and Climate Science Centers to help assess vulnerabilities to the natural and cultural resources management by the Department, and spearhead activities to adapt to the stresses of climate change.
“The WaterSMART program provides a strong foundation for the Department’s efforts to improve water conservation and help water-resource managers make sound decisions about water use,” said Assistant Secretary of the Interior for Water and Science, Anne Castle. “As climate change adds to the challenges we face in managing our water supply, meaningful engagement between the River Basin states and the Department of the Interior will continue to be essential.”
To develop the report, Reclamation used original research and a literature synthesis of existing peer-reviewed studies. Projections of future temperature and precipitation are based on multiple climate models and various projections of future greenhouse gas emissions, technological advancements, and global population estimates. Reclamation will develop future reports to Congress under the authorities of the SECURE Water Act that will build upon the level of information currently available and the rapidly developing science to address how changes in supply and demands will impact water management.
The Bureau of Reclamation is the largest wholesaler of water in the country, providing water to more than 31 million people and to one out of five Western farmers for irrigation of more than 10 million acres of farmland. Reclamation is also the second largest producer of hydroelectric power in the western United States with 58 power plants generating nearly a billion dollars in power revenues and producing enough electricity to serve 3.5 million homes.
The SECURE Water Act Report, with fact sheets highlighting climate challenges and impacts in the eight western river basins, is available online at http://www.usbr.gov/climate.
More information about Reclamation’s WaterSMART program is available at http://www.usbr.gov/WaterSMART/.

TerreKleen Low Impact Development Protector

2011-04-26T21:11:00.003-04:00

Putting in a rain garden? Worried about sediment, trash, debris, or oils getting into and blinding your rain garden? Perhaps you would consider installing our newest product, the TerreKleen LID Protector.

The TerreKleen LID protector was designed in response to concerns of several of our large city clients who are installing rain gardens. Their concerns include: cost, ease of maintenance, sediment, debris, and oils getting into their rain gardens, blinding the rain gardens and killing the plants. In response to concerns about budget and lack of manpower, the TerreKleen LID protector was designed.

This small vault system was designed to capture sediment, trash, debris, and oils, and as a shallow vault, a central maintenance location makes makes $en$e and can easily be performed with a shovel.

TerreKleen LID Protector

Lengthen the life of your rain garden! If you are interested in learning more about the TerreKleen LID protector, give us a call!

EPA Asks for public comment on new proposed permit for stormwater runoff from construction activities

2011-04-24T19:37:00.000-04:00

If you have an opinion about the new EPA proposed permit for stormwater runoff, please contact the EPA. Here is a fact sheet regarding the new proposed permit including instructions on how to comment. If you do have a comment, better get on it soon as there is a 60 day time limitation from the publish date in the Federal Register and I am not totally sure when that was.

TerreKleen hydrodynamic separator installed at Eastchester DPW Yard - TK27

2011-04-20T20:52:00.003-04:00

All of the action started at about
9:00 AM yesterday morning
at the Eastchester, NY DPW yard. Here is the
TerreKleen ready for installation.

The hole where the TerreKleen is being
installed is already prepared.

This is the base which installed quickly.
The white pipes and red hose
are the manifold system. Confined Space
Entry is NOT required on the TerreKleen. This
will mean a significant short and long term
cost savings.

This is the mid-section. Tight installation
since the TerreKleen had to fit right up
against the outlet pipe. The left
side of the unit is the primary chamber
where large sediments, trash and oil
will be contained. The plates on
the right side of this picture shows
the stacked inclined plates where
small sediments will settle out.

The riser is on in no time.

The top stacks in no time.
Total installation time: approximately 1 hour.

The Cost of Nitrogen Pollution on the European Economy

2011-04-13T09:25:00.000-04:00

A first ever report (ENA - European Nitrogen Assessment) was just released outlining the cost of nitrogen pollution on the European Union's Economy.

The study carried out by 200 experts from 21 countries and 89 organizations estimates that nitrogen pollution costs Europe between USD 101 Billion - 461.7 Billion per year or USD 212.00 and USD 1,062.00 per person per annum. These costs are more than double the income gained from using nitrogen fertilizers in European agriculture.

The report also details a number of key assessments of nitrogen pollution including:
Nitrates cause toxic algal blooms and dead zones especially in the North, Adriatic and Baltic Seas and along the West Coast of France in Brittany.
AND
at least ten million people in Europe are potentially exposed to drinking water with nitrate levels above recommended levels.

The study also states that at least half the world's population is dependent on food that is grown with nitrogen based fertilizers but that the environmental costs of nitrogen pollution to Europe are very high and that the benefits of nitrogen abatement achieved by applying and using fertilizers more efficiently and reducing meat consumption outweigh the costs of other options.

Reduce, Reuse, Recycle - it is time to think of roof runoff as an asset. Discounted Rainbarrel Program - sponsored by Aquarion, Connecticut

2011-04-12T10:04:00.000-04:00

Reduce, Reuse, Recycle - it is time to think of roof runoff as an asset.

I was just looking at the USGS seasonal drought predictions. It is eye opening to look at the map of the US and notice the large red and yellow sections which anticipate drought conditions persisting and intensifying in a large part of the south - through June.

We, in the Northeast, are very lucky to have had a lot of snow this winter and it seems right now we are in a good position with our water resources for the next several months. However, we really do not know what is ahead. Why not take this opportunity to maximize your water resources by investing in a rain barrel for your home?

Aquarion Water is sponsoring again this year a discount rainbarrel program. The rain barrels are designed to hold 55 or 60 gallons of water, they attach directly to your down-spout and fill automatically when it rains. They even come with brass attachments, a hose and a screen which prevents insects from making your rainbarrel their home.

Captured rain can be used for lawn watering and car washing or other outdoor chores. It really is baffling to understand why one would need treated water for these activities. In fact, I think my garden grows better with roof runoff!

Here is the link to Aquarion's rainbarrel program
You must order by May 31st for pick-up in Trumbull, CT on June 4th.

It is time for smart water

2011-04-11T14:59:00.000-04:00

I was listening to WNPR radio show "Fresh Air" this morning and heard Terri Gross' interview of Charles Fishman the author of a new book called The Big Thirst, The Secret Life and Turbulent Future of Water. I had to agree with Mr. Fishman's point of view that the golden age of water (defined as: cheap, abundant and safe water) is coming to an end here in the US and that it is time to get creative on ways to save and re-use this limited natural resource as well as take a fresh look at ways to maximize our water resources for the future.

Especially interesting to me were several examples of US cities and industry who have focused on stretching their water resources:

1- City of Las Vegas, NV - Homeowners are incentivized to remove their turf lawns to the tune of $40,000/acre because it is cheaper to pay the homeowner to remove their lawn and re-plant using xeriscaping (native plants that use minimal water resources) than it is to capture and treat for re-use water that would be used for lawn watering in a city that was built in a dessert.

2- Orlando, FL - 25 years ago, Orlando, Florida mandated a that gray water systems be installed in new construction. Orlando uses almost as much gray water as potable water, but have not had to pay to treat the gray water that is used for lawn watering and car washing.

3- IBM Corporation - Vermont. Over the past 10 years, IBM evaluated their factory building and costs associated with heating/air conditioning systems. After careful study, they re-plumbed their building to maximize the efficiency of their manufacturing process by coordinating the needs of the building and manufacturing processes with change in water temperatures as the water flows through the building. The money they have saved by re-plumbing their building adds to their ability for their products to be competitive.

It is time to take a fresh look at how we do things so that we can maximize our water resources.

Superbug (NDM-1) spreads in Delhi sewers

2011-04-08T13:09:00.001-04:00

Scary! Just when you thought it wasn't safe to go in the water! A report published yesterday warns of a newly discovered bacterial resistant gene (NDM-1) has been found in drinking water, sewers and puddles in Delhi, India. This new superbug invades other bacteria including cholera and dysentery and can readily jump to other bacteria. Last ditch anti-biotic treatments will not work against bacteria with the NDM-1 gene.

Honestly, the implications of this are pretty SCARY. It seems a number of patients from UK that sought medical treatment in India, Bangladesh and Pakistan returned with this superbug.

Current stormwater projects and applications

2011-04-05T15:32:00.000-04:00

Was thinking back over the past year and about the projects that we have worked on and what is ahead. Just thought this was interesting to consider what types of projects we work on, their diversity and why our clients choose our systems. These were just a few that came to mind.

TerreKleen - hydrodynamic separator
Probably one of the most unique projects we worked on was for a condo complex in New York. This client needed a hydrodynamic separator to be installed in their existing parking structure. Since there was no room for a crane, we built the whole unit from marine grade aluminum and put it in place. Since this condo complex was located in an urban area, they really were concerned about losing parking availability. Our unit fit in nicely into their parking garage and at the most, they only lost 1 parking spot. (I believe if one drove a very small car they could still fit in the spot)
TerreKleen offers a lot of flexibility. We design to meet the goals of your project (you do not need to design your project to meet the goals of the TerreKleen)

TerreBox - stormwater detention / rain harvesting system
One project that we are currently working on is for a University. They are going to be re-developing part of their campus and in going for LEED Gold, they are planning the installation of a geo-thermal heating system as well as and capturing all roof runoff for re-use. The TerreBox is a natural solution in this application.

TerreBox is a modular system, so the client can easily design the storage they need.
As a system that installs quickly and is HS-25 load rated, TerreBox is well suited for a site where large infrastructure/major buildings are going up.
Work on the rest of the site will be able to continue with minimal interruption.
TerreBox offers a patented water-tight seal. This will prevent the roof runoff from contaminating the geo-thermal system.

TerreArch - stormwater infiltration - patented stormwater arch system

A major portion of projects we see need infiltration. Another school project that we are working on is re-developing their parking lots. Part of their plans include the installation of two infiltration bays. Our systems will fit well in this application because:

Our systems arrive on-site as HS-25 load rated. They are not dependent on work crews to achieve the HS-25 load rating. They are built to easily handle the bus, truck, car traffic at a busy school facility.
TerreArch arrives just in time - there is no need for storage, staging, re-staging and there are no small parts to put together, break or lose.
TerreArch installs quickly - the contractor can install, backfill and cover up to 50,000 cubic feet of stormwater storage in one day. Work on the rest of the site can continue with minimal interruption.
Available as 26" or 48" arches, it is easy to design and install these systems.

Warren County, NY SWCD installs TerreKleen hydrodynamic separator to improve stormwater runoff at AAA rated, historically important, Halfway Brook, Queensbury, NY

2011-01-21T11:32:00.003-05:00

We LOVE what we do because we:
1) Really help our clients improve stormwater runoff
2) What we do has a long term impact on improving water quality
It means a lot to have this opportunity.

During the summer of 2009, we were invited to make a site visit and compete against other hydrodynamic separator units for a high profile project to improve the stormwater runoff that flows into Halfway Brook in Queensbury, NY. Queensbury is located in Warren County, which is located on the edge of a 6 MILLION ACRE Adirondack State Park.

This particular site was selected because:
1- The Warren County SWCD wanted to have the largest impact on improving stormwater and this outfall is the largest in the County
2- A large surrounding commercial area of 106 of impervious surface drains into Halfway Brook at this point.
3- Halfway Brook is a historically important Brook
4- Halfway Brook is a AAA rated Trout Brook
5- Brook trout need cold clean water to thrive
6- Site is upstream from a popular public park

The site constraints were very difficult:
1- The site had a very small footprint
2- A 12" gas main ran through the property
3- Other utilities ran through the property
4- Unit would have to go RIGHT NEXT to the brook, so there is a high water table
5- Runoff from a large commercial area (106 acres of impervious surface) enters the brook at this location
6- Site is right along side a major state route - with lots of traffic
7- The property owner agreed to help at great inconvenience to himself and his going business
8- The site had previously been a gas station - leaky tanks contaminated the site and it had undergone cleanup

The best option at this site would be a hydrodynamic separator. Water could flow down to toward the brook and through the hydrodynamic separator. We demonstrated how the TerreKleen works:

1- Water enters the primary chamber where oils, sediment, trash are collected
2- The water then flows through a screen into the secondary chamber and onto the TerreKleen's stacked inclined plates
3- The water enters the secondary chamber near the bottom of the plates as the water rises the stacked inclined plates help finer sediments fall out
4- Once collected, there is no scour or re-suspension and so the material is permanently collected
5- Maintenance is easy - NO CONFINED SPACE ENTRY is required and most maintenance is completed with a vac truck in about an hour
6- What is really cool is to realize that the stacked inclined plate technology is technology that has been used to separate particles from drinking water since 1905. One would think that if there were a better way to separate particles from water, the drinking water industry would have gone with it. This technology is still widely used and its effectiveness is well known by engineers. The TerreKleen simply adapts this technology to efficiently remove sediments from stormwater.

Details on the TerreKleen:
Each TerreKleen is custom manufactured for each site. We look at flow rates, particle size removal objectives and where the pipes are coming in and manufacture the TK for specific site)
This site has a TK63 - which is our largest unit
TK63 Structure size is: 16.5' X 7' (115.5 ft2)
TK63 offers 403 ft2 Settling Surface Area
The Settling Surface Area per Structure Ft 2 for the TK63 is 349%
*(Please read ft2 as "foot squared - I cannot figure out how to superscript the 2 - thank you)

Here are a few pics:

Just cool to see part of the unit on the ride
up to the site. The weather is sub-optimal

You can see the site here - RIGHT NEXT TO
THE BROOK. The guys told me that brook
trout are always seen right here at the outfall.

The hole has been pre-dug and prepared
for the TerreKleen. The crane is in place and
ready to go. Trucker backs in to
start off-loading the base of the TerreKleen.

Here is the base - in place
This shows the manifold system
which allows the TerreKleen to
be cleaned from the curb.

Here is the middle section of the
TerreKleen getting installed.
This is our largest unit and
these plates will help all of the
fine sediments settle out.

Two hours later and
3 lifts by the crane,
the TerreKleen is in place and ready to work

The TerreKleen is the BEST option at this site.

Not only does TerreKleen maximize the

sedimentation in the smallest footprint, but

the easy maintenance/cleanout will significantly

help keep both short and long-term

maintenance costs to a minimum.

What a great day!

Stormwater Cleanout - Confined Space Entry NOT REQUIRED

2011-01-17T08:46:00.000-05:00

When we talk about stormwater with our clients, one of the most important things we discuss about is The "M" Word... MAINTENANCE. Since we know how time and money intensive maintenance of stormwater systems can be, we try to recommend the most effective stormwater solution with the least maintenance required.

In early January we had installed our second TerreKleen hydodynamic separator in Waccabuc in Westchester County, NY. The first unit had been installed in September. Since we have had lots of snow here in the Northeast this Winter, the first unit was buried in a snow bank, but we were able to "pop the lids" and see how the system was working:

Even though there is snow all over up-top, you can see
once we "popped the lids" that the water is still flowing
through the unit. See trash and debris that has been
collected in the primary chamber.

This is a picture of the secondary chamber. You can see
the plates where finer sediment settles out. See the red hose?
The red hose clips to the top of the unit. The vac truck
operator can energize our manifold system at the bottom
of the unit to re-suspend the sludge blanket.
CONFINED SPACE ENTRY NOT NEEDED for cleanout.

TerreKleen 02 installed to capture sediment and improve stormwater runoff

2011-01-12T22:41:00.000-05:00

A GREAT KICK-OFF FOR 2011! Even though it was a bit cold, it was a great day to be outside and see our first Terre Kleen hydrodynamic separator of 2011 installed!

We are on-site at 7:00 AM and the trucker has already arrived. TerreKleen arrives pre-assembled and ready to install. This makes installation easy.

TerreKleen is quickly off the truck and installing in the hole the contractor has prepared.

The conseal (black strip) is quickly applied. We are now ready to install the riser section.

Riser is being installed

TerreKleen installed!!!

The primary contaminant at this site is sediment. The TK02 is a smaller TerreKleen unit. The size of the TerreKleen for each site is chosen based on flow rates and the sediment particle size that client needs to capture. After pipes are connected and manhole covers put in place, TerreKleen will be fully functioning and will immediately start to work.

TerreKleen hydrodynamic separator approved by The MDC - Hartford, CT

2010-10-27T14:10:00.000-04:00

Attention:

Engineers, Contractors and Owners in

Bloomfield, East Hartford, Hartford, Newington, Rocky Hill, West Hartford, Wethersfield and Windsor, CT!

The TerreKleen hydrodynamic separator has been approved by The MDC for use in projects located within the MDC's jurisdiction. Here is a link to their confirmation letter.

TerreKleen will capture sediment, trash, debris, oils, it installs quickly and there is no scour or re-suspension of collected material. Cleanout is easy and does not require confined space entry. This is a significant short and long-term savings.

Let us know if we can assist with any design and sizing issues!

TerreKleen hydrodynamic separator now improving stormwater runoff at Waccabuc, NY

2010-09-18T13:29:00.004-04:00

It was a beautiful day in Waccabuc, Westchester County, NY. Getting the TerreKleen installed at this site has been a long term project and finally, this past Thursday was the day. The day of our first of two installations at this site. We arrived at about 8 AM and the TerreKleen was already on site.

The installation site was right on the edge of a large open field. Here is a picture of the hole that has been prepared for installation. The contractor had done a lot of work prepping the installation site the day prior so for the most part, upon arrival, the unit is ready to be installed.

Contractor makes some final checks and adjustments, re-confirms the gravel bed is level and cleans out some mud that has accumulated overnight. When everything is confirmed ready for installation, the TerreKleen is lifted off the truck and manipulated into place.

Here is the TerreKleen getting installed into place. A crane easily lifts the unit into place. The TerreKleen arrives fully assembled eliminating any additional work that needs to be done on site.

Here is the riser getting installed. Again, it is a very easy operation - the crane simply lifts the riser and installs it on top of the base of the TerreKleen.

TerreKleens install quickly as they are designed to assemble on-site with each section manufactured to fit on top of each other.

In about an hour, the TerreKleen is installed and ready to work. It will remove sediments, trash, debris and oils.

For more information about the TerreKleen or if we can assist you with information about hydrodynamic separators, please contact us at www.stormwaterworks.com

Meet us at these upcoming stormwater tradeshows!
