TerreKleen hydrodynamic separator now improving stormwater runoff at Waccabuc, NY

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.

Wanted to post a few last pictures so you can see how the installation was completed:

Off the truck, the crane is moving the TerreKleen into position.
Easy does it!  TerreKleen is gently lowered into the hole

Improving Stormwater runoff at Ausable River, in a NYS DOT right of way- 3 part post

Wilmington, NY.  The Ausable River in the Adirondack Mountains in upstate New York is known for its world-class trout fishing.

This is the site of our first TerreKleen hydrodynamic separator installation in upstate NY.  The TerreKleen hydrodynamic separator is being installed to capture sediment, trash, oils and debris and prevent its flow into the Ausable River.  

This project is a collaborative effort between Essex County Soil and Water Conservation District and NYSDOT.  The installation of the TerreKleen is in a NYSDOT right of way.

This is a picture of the Ausable River from the site.

Difficult installation site conditions include:
Re-routing traffic on this section of Route 86 until installation complete, small site footprint, excessive low hanging power lines.

This is a look at sediment on this site.

This is an overview of the site as the TerreKleen 
arrives.  This part of Route 86 has been closed for installation.
