Anaerobic systems incorporate the use of flexible membrane covers to collect methane gas. This methane gas is collected from around the perimeter via a perforated piping system and then processed in either flaring or co-generation. Specially designed weights and floats are attached to the cover membrane, which cause the horizontal ‘planes’ or ‘plates’ of the cover to be under tension in two directions. This tension eliminates slack in the cover, providing necessary stability across the surface, as well as clear drainage. Besides providing tension, the weights and floats define the precise location and size of rainwater sumps. At the bottom of the sumps, automatic submersible pumps are placed to discharge rainwater from the cover to wastewater outside the lagoon basin.
