<p>The present invention relates to a cooling apparatus and method wherein a supply sump and turbine are below grade. Water cooled from an above grade cooling tower fan and fill flows into the supply sump and is pumped though below grade pipes into a facility. Heat rejected water from the facility then flows through below grade pipes into a below grade collector sump. A collector sump pump pumps the heat rejected water above grade into a nozzle and back into the fill to be cooled. The present invention is contructed such that water is not idle in any above grade component. Accordingly, the risk of water freezing within the above grade components is drastically reduced. Moreover, the heat rejection water can by-pass all above grade components and travel directly into the supply sump in the event of reduced load from the facility.</p> |
