Vertebrae™ Optimized Construction

Our Vertebrae™ designs have several unique characteristics.

Well Construction Specifications +

Vertebrae™ well segments (screened sections or well sections) are composed of unique materials that allow pre-fabrication and flexibility and are Patented with additional Patents Pending. The well materials perform better than traditional well materials. For instance, our well screens are generally 1 inch nominal but have nearly a 60 slot opening. This equates to 5 sq in per foot open area, which is 7 times that of 3 inch longitudinally slotted screen and 3 times more than 1 inch 10 slot well screen. The wells are generally covered in a geotextile providing the optimum multipurpose design.

The risers and tubing is placed in a sleeve (an outer conduit). This is also HDPE and allows quick installation, protection from damage, and one of the greatest features; protection from occlusion. Combined with the large open area, Vertebrae™ wells develop faster than any other wells.

We also design with 1.25, 1.5, and 2 inch nominal segments for vapor extraction and other custom designs.  In many instances we have data feedback indicating these larger screen diameters were unnecessary due to the excellent characteristics of the 1 inch Vertebrae™ segments.

Risers or conveyance tubing is composed of High Density Polyethylene (HDPE) tubing. This tubing is durable, flexible, chemical resistant to most contaminants and reagents as well as ozone. The rated pressures are similar to the sch 40 piping commonly used in the industry. In some instances, alternative tubing is available (ie. Teflon for Ozone).

How many wells can you get in a sleeve?

That is the bases for the design. We design to optimize the amount of control, while keeping the bore and installation as low key as possible. The table below shows some of the various packing limitations (note not all tubing sizes are stocked).
