Product Description

REVOC Defined Sump Covers use floats and weights to create rainwater collection sumps in the cover and to accomodate changes in water level. The REVOC Defined Sump system is ideal for larger floating cover applications. A defined sump system can be fairly simple, or can be exceptionally complex depending on site conditions. REVOC Defined Sump Covers are used for all floating cover applications including potable water storage, odor control, evaporation control and contamination/dilution protection. A REVOC Defined Sump Cover cover is the most versatile cover system and can be used in any floating cover application especially large ponds, or ponds with an irregular shape. Layfield's REVOC Defined Sump Cover designs, installation techniques, and inspection/maintenance protocols fully meet the requirements of local regulations, such as the AWWA M25 Lining and Floating Cover Guidelines and AWWA California-Nevada Reservoir Floating Cover Guidelines. Layfield designs, installs, and maintains all types of floating covers.
