Improving Stormwater at N. Lake Carmel with a second installation of the TerreKleen

All Equipment in the shoulder
Very Tight Work Area

It has been an exciting August with our second TerreKleen installation at North Lake Carmel, NY.  Again, the worksite is incredibly small.  All of the heavy duty earth moving equipment barely fits in the road shoulder.  It is important to keep the traffic moving. 

TK09 - 9 cells for particle separation
Don't blink!  (Left) 
The TerreKleen is in place before you know it!  

This is the picture of a smallest TerreKleen unit, the TerreKleen09.  

The 09 represents the number of cells created by the stacked inclined plates for particle separation.  This unit will capture sediment, trash, debris and oils.  

Confirming the TK09 is level
Next step... 

double checking that the TerreKleen has been installed and is level in the hole.

It is important that the gravel in the bottom of the hole provides a level surface for the TerreKleen to sit on.

The crane is moves the lid onto the open TerreKleen.  The top is designed to fit on top of the open TerreKleen.  It takes just a few minutes until the lid is in place.

The installation is complete.  In less than an hour, the large equipment is leaving the site and the TerreKleen is in place ready to do its job.

Hydrodynamic Separator - TerreKleen 45 is now capturing sediment, trash and debris at N. Lake Carmel, NY

This was a very exciting day!  The effectiveness of the TerreKleen hydrodynamic separator for capturing sediment, trash and debris is well known and these units are widely used in VA, MD, PA, NJ and DE.  As the representative for TerreHill Stormwater Systems in New York and New England, was  thrilled to see our first installation of a TerreKleen in New York State!  What made this day even more exciting is that the unit is a TK45 - the largest unit we have ever seen installed.

 This is a picture of the jobsite.  The N. Lake Carmel community is mainly residential, however, there is A LOT of traffic.  I took this picture to give you an idea of how small the work area is.  A shoring box is hidden behind the orange netting - this is where the TerreKleen is going to be installed.

This picture is looking down into the hole that has been dug for the TerreKleen.  It is important that the gravel in the bottom is level.  Since this is a lakeside community, there is a high water table and you can see that some mud has creeped into the hole.  The mud will be cleaned before the TerreKleen is positioned in place.


 This image shows the base of the TerreKleen as it is being maneuvered into place.  It just takes the crane operator a few minutes to lift the base off the flatbed truck and position the base in the hole.  

This is the base of the TerreKleen.  You can see the manifold system (white bars and red hose on the left side of the unit) are designed to assist in cleaning the unit.  Notice the white socks on the right side of the unit designed to collect oil.

Next, the middle section or "riser", is positioned into place with the crane.  This picture shows the stacked inclined plates on the left side of the unit.  This is where all of the fine particle separation takes place.  Stacked inclined plate technology was developed in 1905 and has been widely used in the drinking water industry around the world ever since.  The Terrekleen merely adapts this proven technology and widely accepted engineering practice for the storm water industry.  The riser is made to fit ontop of the base.  It takes just a few minutes to get this piece into place.
The lid is placed on top of the TerreKleen.  This lid incorporates 3 manhole covers for cleanout as well as a catch basin grate.  This unit will function as the last catch basin in the line and will provide 3 other access points to aid in cleanout.

This TerreKleen unit was installed in about an hour.  The TerreKleen will contain trash, oil and sediments until the units are cleaned out.  No scour or re-suspension of collected material happens because of the design of the TerreKleen.

Stay tuned - we have an additional installation in North Lake Carmel that will be posting shortly.  We are excited to help keep North Lake Carmel clean!

TerreKleen Hydrodynamic Separator installation in Kent, NY at N. Lake Carmel this week!

Coming up this week... the installation of a TerreKleen TK45 hydrodynamic separator in Kent, NY at North Lake Carmel!  Took the day Friday to visit the installation site in Kent, NY.  

The TerreKleen being installed is going to capture trash, sediment, oils, and prevent them from traveling into North Lake Carmel.    

TK45 is capable of treating large flows and will improve the water quality that flows into North Lake Carmel.  Stay tuned for installation pictures later this week!
