Typical 3 or 7-Channel CMT Installation using
layers of bentonite and sand backfilled from surface.

The 403 CMT® Multilevel System provides the simplicity and low cost of a bundle-type installation, with the benefits of backfilling or sealing around a single tube, with no joints.

The CMT System uses continuous polyethylene multichannel tubing which is custom-built on site with screened intervals at desired sampling zones. CMT Systems are inexpensive and easy to install. In-field design flexibility allows the number of monitoring ports, port locations, and monitoring strategy to be finalized right on site.

Monitor up to 7 discrete zones in the 1.7" (43 mm) System and 3 zones in the narrow 1.1" (28 mm) System. Reliable seals and sand packs can be placed using standard backfill methods, or using sand and bentonite cartridges on the 3-Channel System.

Water levels can be accurately established and samples taken using small diameter portable equipment available from Solinst. Wellhead seals are also available to allow vapor sampling.


Solinst offers no-charge virtual CMT training that provides both instruction and hands-on demonstration for CMT construction and installation. Individuals who participate and complete the course in person or online are "Trained CMT Contractors" and can be listed on the Solinst website.
