Flowlex Civil & Plumbing provides licensed installation and service for storm drainage, septic systems, and grease trap infrastructure throughout South Florida. Every project is permitted correctly, engineered to code, and completed without a callback.
Every project is scoped, permitted, and inspected under a single contractor — eliminating the need to coordinate separate providers for drainage, septic, and grease trap work.
We design and install catch basins, area drains, and underground piping systems that manage stormwater runoff and protect your property from flooding.
Flowlex installs, repairs, and maintains septic systems engineered for South Florida's high water table, with proper permitting and inspection at every stage.
SPEC 03
From under-sink units to full in-ground interceptors, we size and install grease trap systems that keep commercial kitchens code-compliant.
Our team evaluates the property, reviews site access and soil conditions, and determines the appropriate system for your project.
We prepare and submit all required permitting documentation with the local jurisdiction on your behalf.
A licensed crew completes the installation with properly sized equipment, leaving the site clean at the end of each day.
We coordinate and attend the final inspection to ensure the project closes out correctly the first time.
Flowlex Fleet
Most of our work is installed below ground, where it cannot easily be corrected after the fact. Every project is approached with that standard in mind.
Every project is permitted through the proper channels and completed under a valid inspection — not an informal agreement.
Systems are engineered and sized for local soil and groundwater conditions, not a generic specification.
Storm drainage, septic, and grease trap work are managed by a single contractor, with one point of contact and one project schedule.
