Environmental Engineering


W. Kevin Walker, P.E. provides expert site investigation for design of on-site waste-water disposal (septic) systems in the State of Arizona and Mr. Walker can design both conventional (gravity-flow) septic systems and alternative systems (required by law for sites where unsuitable conditions do not allow for design conventional septic systems).

Further, W. Kevin Walker, P.E. is one of the few engineering companies in Southern Arizona to provide soils reports for foundation design and comprehensive septic system designs for the same project. This results in reduced costs to the client due to the efficient use of only one site investigation program that supports both foundation engineering and septic system designs.
W. K. Walker, P.E. also provides consulting services for the design of projects adjacent to known flood-prone areas.
