The patented rotary weir functions as a continuous high volume surface skimmer, providing water quality benefits while connecting to pipes up to 24".  Both economical and mechanically reliable the rotary weir is also the perfect device to use when measured flow rates are necessary.

Water level control with accuracy to the fraction of an inch combined with fully customizable drawdown parameters makes this freestanding device one of the most versatile water control tools available. Modular design allows the rotary weir to be custom fitted to each pond based on managed pond depth, maximum overflow depth, and desired flow capacity.
