DYK Incorporated - Prestressed Concrete Tanks

Because it's a good thing if neighbors ask "What water tank?"

Sensitivity to site design is one DYK's top priorities. DYK has built tanks on nearly every type of terrain from hilltops to flatlands and uses many techniques to reduce the tank's visual impact. These techniques include partial to full burial and architectural disguise. Our full burial means your tank completely disappears from view and allows for multi-use land options (so we can build playgrounds, gardens, cul-de-sacs or landscape on top of it!).


This 3.0-MG tank uses a paint scheme of arches and a parapet roof to help liven the tank's appearance. Inspiration for this treatment came from a nearby mission.		These two 0.75-MG flow equalization basins have been textured with horizontal grooves to help break up the flat appearance of the wall.

Architecturally disguising tanks reduces the visual impact of above grade tanks.

Although unadorned, above grade DYK tanks look good, through the years we have used a variety of architectural treatments to help reduce their visual impact. This ranges from a simple two-tone paint application to an external system with precast textured panels.

Wherever possible we design and integrate the architectural treatment to provide the maximum durability and the lowest possible maintenance.


Adding raised pilasters and arches to the wall surface has enhanced this 2.25-MG tank in Daly City. This tank is also built into a hillside. Using differential backfill on the tank allows minimum excavation and when complete seems more a part of the landscape.		This tank has been fully buried, but the roof left exposed. This minimizes the cost of the roof and from ground level eliminates all visual clues that a tank is there.


Here a tank was fully buried. A tennis court was installed on top to further disguise the tank and provide a recreational area for the community.		This tank is completely buried with a playground built on top. The community benefits not only from water storage, but has a new park to boot!


This tank is fully buried with a park on top. The landscaping and concrete walks in the park reflect the circular shape of the tank beneath.		To visually replace an existing open reservoir this 10.0 MG tank is completely buried with a reflecting pond on top. The pond is extensively landscaped and even includes a series of waterfalls.
