Abstract

A membrane cover is mounted at the surface of a wastewater reservoir. T he membrane cover has a flexible buoyant impermeable membrane affixed to the perimeter walls of the reservoir and loosely laid over the wastewater level inside the reservoir. An array of weight lines is anchored to the perimeter walls and is loosely laid over the impermeable membrane. The array of weight lines defines a rectangular herringbone pattern. An array of drains is also provided. Each drain is disposed along one of the lateral weight lines. The membrane cover also comprises an array of troughs formed therein under the array of weight lines. A water ballast having the continuous herringbone pattern is contained within the troughs. Because of this water ballast, the membrane cover is kept taut and stable during a rainstorm and a surface thereof exposed to uplifting wind forces is minimized.
