In 2002, Lake Merced Golf Club (along with two other clubs in the vicinity) entered into an agreement with the City of Daly City to begin using tertiary-treated waste water in combination with fresh water from the Club's private wells for the irrigation of the golf course.

In response to this agreement, DBD Structures was engaged by the Club to design, permit and construct a revolutionary new water tank and pump station to store, mix and pump, this blended water well/tertiary water into the course's irrigation system.

The 16 foot high walls of the reinforced, cast in place concrete water tank are founded below grade. The water tank has a center wall, allowing the separate storage of equal amounts of well water and tertiary-treated waste water. The roof of the water tank and pumphouse enclosure were custom designed and manufactured by Star Building Systems. All structural members supporting the water tank roof are galvanized, including the 82 foot long support beams.

The pump station consists of two sets of pumps, one set for well water and the other set for tertiary water, which automatically supply variable ratios of mixed well water and tertiary water to the course?s irrigation system. The operating system for the pump station is automatically controlled by Lake Merced Golf Club's irrigation control software which is located remotely.

The design of the system includes overflow piping which drains to a 500,000 gallon emergency retention pond which is located on Club property.
