At APM & Associates, we understand that water and wastewater treatment plants play an integral role in our city’s health and well-being. We have a history of designing and restoring pump stations and other treatment plant structures with an unyielding commitment to safety and sustainability (quality, current safety policies and cost-effectiveness.  We strive to deliver cost-effective projects every step of the way, from the design, to the construction, to the start-up, to – perhaps most importantly – the continued management, and operation and maintenance of the plant.

Since our inception, APM has provided exceptional design services for the upgrading and rehabilitation of pipeline systems throughout the State of Texas. In fact, a significant portion of our business can be attributed to the pipeline design contracts that we have worked on. We understand that conventionally the designs were open cut construction, but we understand that with ever increasing need to be cost effective with public funds and the indirect cost of open cut, that we must look at every alternative to the design to ensure the most effective designs are being proposed.
