SBuilt-in flexibility makes Ovivo’s FlexScour® underdrains an ideal choice for retrofits. The FlexScour underdrain was originally developed as a retrofit system that would be sufficiently flexible to accommodate any existing pipework and tank arrangements without compromising efficient flow management. FlexScour underdrains do not require false floors – they are an anchored system, not a grouted system. This ensures rapid, straightforward installation, ideal for rehabilitating older filters.
The low, five inch high laterals also allow for extra filter media depth (meeting today’s most stringent effluent quality standards) and clearance for air-scour bed expansion without raising the launder elevation.
