ISSZT (In Situ Saturated Zone Technology) for Unlined Landfills

Click for full size image

In Situ Saturated Zone Technology (ISSZT) is a patented technique which is used to lower the groundwater -- without pumping - in order to create an unsaturated condition within and beneath an existing unlined landfill.

Its low capital and operating cost is an attractive alternative to existing groundwater removal and treatment.

Many of these unlined landfills - whether abandoned or undergoing active remediation - already have installed caps and/or perimeter barriers. These are the major capital cost components of the ISSZT system when used for containment.
