About
Murphy Cormier General Contractor Inc. has been designing, installing, and maintaining commercial sewer systems in Lake Charles, LA since 1971 — over 55 years of continuous operation serving the Cajun Coast region. Founded on the patented Hoot Sewer System technology invented by Murphy Cormier himself, the company has built a reputation as a regional leader in eco-friendly, low-pollution sewer infrastructure. For facility managers and property owners overseeing commercial assets in Lake Charles and surrounding Southwest Louisiana, that longevity translates directly into deep local code knowledge and proven field experience across a wide range of project scales.
The company's commercial capabilities are substantial: their precast production facility can yield up to 25,000 gallons of treatment capacity per workday, and they engineer systems rated to handle flows up to 2 million gallons per day — a scale relevant to industrial facilities, large multifamily complexes, warehouse and distribution centers, and institutional campuses. Commercial sewer system design and construction is a core offering, with each project customized to the client's operational footprint.
For ongoing facility maintenance, Murphy Cormier offers scheduled grease and sewer pumping services, including the option to establish a recurring pump-out schedule — a practical solution for retail properties, food-service tenants, and mixed-use buildings where grease interceptor compliance and sewer system performance are non-negotiable. Their vacuum truck services support drain and sewer maintenance needs across commercial and industrial sites. The team also handles system repairs, component replacements, and custom precast concrete work for specialized infrastructure requirements.
Property managers and general contractors in the Lake Charles metro looking for a commercial sewer specialist with deep regional roots, scalable engineering capacity, and a documented environmental compliance focus will find Murphy Cormier a well-established partner for both new construction and ongoing facility maintenance.
