Fountain Vault

Construction of the new Electric Fountain vault began in January after a delay caused by the holiday snow storms. The foundation slab is 3 1/2 feet thick and the outer walls, like the original, are battered with a taper from two feet thick at the base to one foot thick at the top. The vault deck, which holds all of the water feature manifolds and nozzles, is sixteen inches thick and the parapet wall, which hides all this plumbing from view, is one foot thick.

Fountain Deck

The new Electric Fountain duplicates the original 12 water displays but will use modern plumbing techniques to distribute the water to the nozzles. Both water pipes and electrical conduits penetrate the roof of the new fountain vault to service the nozzles and lights on the fountain deck. When the fountain is in operation, the vault deck is flooded to a depth of 30 inches behind a parapet wall.

Colin Goodrich (Hobbs Architectural Fountains) and Gary Coffey (Concrete Works of Colorado) hold one of the 2" steel water pipes that will be embedded into the fountain vault roof.

Sixteen inches of concrete will be poured on this wooden form after the re-bar is installed and the precision placement of these pipes is confirmed. The manifolds holding the individual nozzles will attach to these pipes.

The concrete for the deck is being poured in these pictures. A hose from a concrete pumping truck allows the concrete to be fed from above so that it may be directed to flow in all areas of the deck.

A vibrator is used to get the concrete to flow into the spaces between the re-bar and around the embedded water and electrical supply pipes.

Parapet Wall

The last concrete pour was for the parapet wall, which hides the fountain plumbing from being seen from shore. When the fountain is in operation, a pool of water is formed behind the wall to provide a stilling basin and cooling for the fountain lights. The water falling back on the fountain deck spills over a weir on the east side of the fountain back into the lake.

PVC pipe was cut in half to form the bullnose ornamentation around the outside of the parapet wall.
The multi-layer pier cap was formed as part of the parapet wall. It provides the base for the ball finials.
With the forms removed, all of the details of the vault and parapet walls can be seen. A thin horizontal line shows where the vault walls join the 16 thick deck. The rectangular openings at the base of the parapet wall allow the fountain deck to drain back into the lake when the fountain is shut off.

The twelve ball finials on the piers disappeared from the old fountain some time in the 1930s. One of them was spotted in the mud when the lake was drained. The new ones were made to match the originals.

The entire fountain vault structure was coated with a waterproofing membrane, sprayed on at high pressure. The color turned from white to yellow with exposure to sunlight, matching the shade of the original fountain paint. This photo was taken on May 18, 2007, just before the water flowed back into Ferril Lake for the first time in 7 months.
