Method and apparatus for controlling the discharge or continuous bleed-off of cooling water of evaporative coolers and cooling towers includes a container for receiving water from the cooling water system via a float valve operated float valve. An orifice at the bottom of the container allows water to flow to a device for eliminating suction effects or depression caused by the hydrostatic head of water below the container and a cleaning device, operated by movement of the float valve keeps the orifice clean.
