Water Tanks

While not entirely historical, Walnut Country features two water tanks that provide water and its pressure to hydrate the acres of landscape that keep our community so beautiful throughout the year.

One water tank is located in the center of the Greenbelt, just south of the lower tennis courts. The second water tank is located on South Larwin Avenue across the street from River Ash Court and Stone Canyon Court.

Weeping/Leaking Water Tanks?

The water tanks will probably leak, also called weep, for the foreseeable future. The tank is made of thick redwood planks that are held together with the metal bands that surround the tank. The planks are not joined to each other in any other way.

The tank is filled with water from the well right next to it, and the water is used to irrigate the Greenbelt. Different sections of the Greenbelt are watered every night except Tuesday, because on Wednesday the grass is mowed and needs to be dry.

As a result, the tank never gets more than half full (the well pump operates 24/7), except on Wednesday. From Thursday to Tuesday, the top half or so of the tank remains dry and the redwood shrinks as a result. When the tank begins to fill on Tuesday night, water will leak from the spaces between the dry, shrunken planks until those planks absorb enough water to expand and seal. This is a natural process of redwood tanks. Most of the water weeped is then absorbed back into the ground from which it came.

Greenbelt Water Tank


SmokeStack Memorial

The Cowell Smokestack was removed on June 15, 2009. The Smokestack was built as part of the Cowell Cement plant in 1936 to replace eight smaller stacks; this smokestack reached 235 feet. The Smokestack was actually a cement stack designed to ensure cement dust would be spread far from the surrounding farmland.

Fondly recalled as a landmark for pilots landing at Buchanan Airport and locals to know that they are almost home, the Smokestack was removed because it had become a safety hazard with falling cement and a major earthquake danger.

In the Smokestack’s place is a memorial in the Greenbelt.
