Tesla Hydroelectric Regulating Reservoir Liner -

Material Type: 36 mil Hypalon Geomembrane
Size: 800,000 sq. ft.

Project:
A large impoundment,Tesla Regulating Reservoir is an earthen dam designed to regulate water levels for hydroelectric production.

Challenge:
 This project involved the fabrication and installation of 2 million sq. ft. of geotextile, geocomposite, and geomembrane. The project presented challenges in its long steep slopes and vast lineal feet of mechanical attachment.

The successful installation and subsequent performance of our lining system, inspected each year since its completion in 1996, remains functioning as designed and intended, serving its community.

Material:

The geosynthetic design was an 8 ounce Non-woven geotextile underlayment under the entire lining system, with a single sided composite drainage net along the face of the dam and approximately 1/2 way out into the reservoir. These products were then overlain with a 36 mil Reinforced Hypalon geomembrane.

Geosynthetic materials build a better project at a better price calculated over the long haul — including the savings resulting from less maintenance and reworking.

Panel Layout:

This project involved the fabrication and installation of 2 million sq. ft. of geotextile, geocomposite, and geomembrane. Long steep slopes (ranging from 130' to 190') and 7,000 lineal feet of mechanical attachments added to its complexity.

Due to the large fabricated panels, CLI used a 25-man installation crew. All materials were laid out on CAD and each panel was labeled by location and date of fabrication for efficient deployment.

Project completion - on time and budget.
