Wessler Engineering FacebookIndustrial | Wessler Engineering


Local, state and federal regulations for industries are constantly changing. At Wessler Engineering, we work with industries to prepare the plans and permits required to comply with these regulations. In addition to the need for compliance assistance or site development for facility expansion, industries are also likely to need wastewater treatment, new or upgraded electrical systems, and an emergency action plan. Additionally, many industries are making a push to become more sustainable and environmentally friendly.

We are able to assist our industrial clients by preparing plans and reports, providing hazardous waste training, conducting routine audits and inspections, designing site development improvements, wastewater and sewer system upgrades, and new or upgraded power, lighting, and control systems. Whatever the solution, we work to complete each project successfully, on budget, and on time.
