Side-Slope Pumps Replace Crusty Submersibles

A large cylindrical top-head drive pump lies on its side in an open grassy area. Several pipes extend from the pump, which seems to be disconnected from its original setup. A wooden stake and additional piping are visible nearby. The sky is partly cloudy.

After Hot, Aging Landfill Adds Gas System, Blackhawk Side-Slopes Take Over for Crusty Submersibles

A large, older landfill in a Southern state was baffled by significant changes in its operating characteristics after installing a landfill gas system.

The conscientiously well-run site, opened more than 20 years ago, always has been challenging — extremely harsh, hot and highly volatile. The regional gas manager called it more than a typical landfill, with high variability and breadth in the stream of accepted waste — 40-50 percent trash, 10 percent construction debris, plus significant amounts of industrial waste, bio solids, sludges, solidified liquids, offset products, ash and heavy metals. Industrial waste and fill are used as cover. There is little oxygen and no leachate fingerprint, the manager says.

HORIZONTAL SOLAR PUMPS DEWATER CANYON WELLS

A solar panel is mounted on a metallic frame on a dirt hill. Nearby, a large, green pipe partially buried in the ground is connected to a top-head drive pump in a metal box. A smaller metal cage-like structure on the ground houses electrical equipment.

INNOVATIVE PUMPING OFFERS HORIZONTAL GAS PIPE DEWATERING SOLUTIONS

Company to dewater remote gas wells no longer served
by electric or pneumatic power.

The closed Class D site includes 6-inch vertical wells
to depths of 100 feet with a 1¼-inch gas discharge.
More challenging has been dewatering near-horizontal
side-slope trenches in the closed section of the landfill.
Some customizing and experimenting with Blackhawk
Apollo™ solar piston pumps have been most effective.
