Glenample Hydro Electric Company | Glenample Hydro Scheme

egeplast PE100 Black Pipe | Transition Pieces | Fabricated Fittings

Requirements

A Government initiative to generate sustainable power for residential properties, the Glenample hydro-electric power generation scheme was built in the Trossachs National Park at Lochernhead. The Glenample Hydro Electric Company and principal contractor, Green Cat Contracting needed a robust PE pipe system which could transport rainwater down the hills around Loch Lomond to a turbine and power generation unit, and withstand the high water pressures involved. egeplast UK was asked to recommend and supply a suitable pipe system via merchant Keyline Civils Specialist.

Solution

egeplast UK supplied 1.64km of its black PE100, high density polyethylene pipe and fabricated fittings. Lightweight but highly durable, egeplast Black PE100 pipe, also known as egelen pipe, was supplied in multiple diameters and lengths.

PE100 pipe provided comprised 450mm OD SDR21 Black PE100 pipe, 450mm OD SDR17 Black PE100 pipe and 450mm OD SDR13.6 and SDR11 Black PE100 pipe in 12 metre lengths plus 500mm OD SDR9 PE100 Black pipe in 13.5 metre lengths and 500mm OD SDR9 PE100 Black pipe in 6 metre lengths. Multiple transition pieces enabling the connection of pipe with one SDR rating to pipe with another were also supplied.

Factors effecting the pipe spec included external forces such as the weight of soil and turf around the pipe, long term durability and, because pipe would be transported by helicopter across and to the installation at the top of the hill, pipe weight.

Outcome

Working with Green Cat Contracting and Keyline Civils Specialist, egeplast UK successfully completed the project for this important hydroelectric power generation scheme.
