Repairs needed at city's sewage lagoon

A million dollar liner at one of the city's sewage lagoon started to bubble and tear in recent weeks.

City engineers expect to start repairs at one of the local sewage lagoons in coming weeks after the pond's protective covering started to bubble and tear.

Located south of Mountain Home off South 5th West Street, problems at the lagoon were first reported in mid-August and continued to worsen, according to Public Works Director Wayne Shepherd.

The issue concerns a plastic liner at the bottom of the 60-acre pond, which keeps treated waste water from leeching into the ground. Composed of thick high-density polyethylene, pockets of methane gas started to form beneath the ground and sections of the liner along the pond's eastern wall. Like a balloon filled with helium, the excess gas caused the material to bubble, lifting it seven feet to the water's surface.
