If you need trenching and installation for underground utilities, call on Cook Engineering in Northern California. We have installed hundreds of miles of water, gas, sanitary sewer, and drainage pipeline. Our crews also will perform excavation for electrical and communication conduits.

In addition, other underground utilities we install are pre-cast and cast-in-place. Structures used for septic tanks, utility access holes, drainage inlets, stormceptors, storm drain clarification, and detention systems, sanitary sewer vaults, restaurant grease traps, and culverts.
