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.
