Market Introduction

Access where the facility can't.

Zion Marine has held a multi-year diving services contract with DeKalb County, Georgia for ten years. Public infrastructure, water systems, dams, bridges, ports, holds its most consequential conditions below the waterline, and public owners need those conditions documented to procurement and safety standards. Zion Marine provides the underwater access to inspect, document and repair submerged components for federal, state and municipal owners, with the registrations and reporting public procurement requires.

public owners on our project list: U.S. Army Corps of Engineers, Georgia DOT, City of Tuscaloosa, City of Orlando and JEA.

Common challenges

What we're usually called in for.

The operational conditions that lead an owner to call.

Strict safety & regulatory compliance

Federal scopes require strict adherence to USACE EM 385-1-1 and ADCI standards. We plan and document operations to those requirements.

Formal contracting & documentation

Public procurement requires verified registrations, bonding and standardized reporting. We provide the documentation procurement officers need.

Inspection requirements

Public infrastructure owners face regulatory and condition-rating inspection requirements. We deliver reports that meet those standards.

Unknown submerged conditions

Public assets are often long uninspected. We provide the condition assessment owners and engineers need for planning and funding.

Emergency & failure response

Public infrastructure failures, blocked intakes, failed gates, need a compliant response. We mobilize to the condition.

Prime contractor support

Public projects often run through prime contractors. We support primes with the diving scope, documentation and safety records they require.

Dams

R.M. Clayton Water Plant Improvements

Owner: City of Atlanta · Levee: U.S. Army Corps of Engineers · GC: Astra Group · Atlanta, Georgia · 2025–2026

Two scopes at the City of Atlanta's R.M. Clayton water plant. At the levee outlets, underwater installation of four custom backflow prevention devices: a 9 ft hinged valve, a 48 in duckbill check valve, a fabricated sliding gate and an 8 x 7 ft hinged valve, with fabrication support, rigging and diver installation. At the plant, chlorine contact chamber modifications.

Bridges

Pile Jacketing, SR 2 & SR 52 Bridges

Owner: Georgia DOT · GC: Massana Construction · Georgia · 2024

Underwater pile preparation and installation of 148 linear feet of integral jackets, 34 to 60 in, on SR 2 over West Chickamauga Creek and SR 52 over the Conasauga River. Grade-level dredging and pumped fill were performed from floating platforms with surface-supplied air.

Water

Lake Tuscaloosa Water Intake Upgrade

Owner: City of Tuscaloosa · GC: Haren Construction · Tuscaloosa, Alabama · 2024

Removed the existing timber intake and rock ballast and installed a new intake with diver-placed steel formwork, rebar and concrete. Replaced the screen guide rails and the air-valve intake. Surface-supplied air was run from a barge at 110 ft depth with surface oxygen decompression, an on-site chamber, a chamber operator and a dive medical technician on standby.

Operational facilities

Working around operating infrastructure

Public infrastructure usually has to remain in service during inspection or repair. We coordinate with the owning agency on access, safety and documentation, and plan each scope around the operational and regulatory constraints the asset allows. Scopes are evaluated for flow, isolation, access and safety before the crew enters the water.
