New Oil Water Separator for Rye Brook DPW!
It was a bit chilly this morning when we arrived on site at the Rye Brook DPW garage on West William Street. As the representative for Terre Hill Stormwater Systems, we wanted to be on site for the delivery. One particular word comes to mind.... BURRRRRRR. Yes, folks, it was COLD!!!!
The trucker was already on site and preparing the unit for easy off-loading from the truck.

| See all of the white stuff? At this point, it has been so cold is solid ICE!!! |
 |
| The yellow color is a special liner that will protect the box. |
 |
| Here it is.... the oil/water separator and the lid. This unit will be installed in the ground in the next few days. |

Warren County, NY SWCD installs TerreKleen hydrodynamic separator to improve stormwater runoff at AAA rated, historically important, Halfway Brook, Queensbury, NY
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! PS - here is a link to project details prepared by Warren County Soil and Water Conservation District |

Stormwater Cleanout - Confined Space Entry NOT REQUIRED
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
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. |
