Core Services
Built around water, soil and infrastructure.
ABD combines irrigation troubleshooting with real field construction capability—so the same team can diagnose the problem, expose it, repair it and verify the result.
Water Efficiency & Leak Detection
Baseline flow testing, zone profiling, pressure checks, water-loss investigation, scheduling review and prioritized corrective work.
See our approachDrainage & Stormwater
Runoff-path diagnosis, drainlines, catch basins, swales, erosion repair, outlet protection, grading and post-storm restoration.
Request a drainage reviewWaterlines & HDPE
Private waterlines, irrigation mains, HDPE/IPS piping, isolation valves, pressure regulation, utility trenching and repair support.
Talk waterline scopeExcavation & Sitework
Trenching, tight-access excavation, grading, bedding, backfill, compaction support, hauling, clearing and infrastructure exposure.
Plan siteworkAgricultural & Landscape Systems
Farm irrigation, orchard distribution, drip systems, establishment irrigation, landscape restoration and water-conscious retrofits.

Built in the field. Documented on Maui.
A curated portfolio of real project conditions from Garrett McMillan’s work archive—showing irrigation infrastructure, excavation, drainage-related conditions, site restoration and equipment-supported work without social-media overlays or unrelated account tags.
Excavation & Site Protection
Controlled excavation with the surrounding property protected.
Ground cover, access control and careful machine positioning help keep excavation work organized while reducing unnecessary disturbance to finished areas.
Irrigation Infrastructure
Water-service and backflow components exposed for service.
Field access to irrigation source components allows pressure, isolation and downstream system conditions to be evaluated before repairs are buried again.
Controls & Diagnostics
Controller systems are part of the diagnosis—not an afterthought.
Station wiring, modules, sensors and field devices are reviewed together so operating problems can be separated from hydraulic failures.
Valve & Manifold Repair
Rebuild the infrastructure cleanly, then make it serviceable.
Valve and manifold work is laid out with future access, isolation and troubleshooting in mind—not simply patched enough to disappear underground.
Drainage & Damage Assessment
Understand the failure path before rebuilding the surface.
Washouts and undermined pavement are symptoms. ABD evaluates where water entered, how it moved, what failed and where a durable repair needs to discharge.
Site & Grade Conditions
Landscape, grade and retaining conditions all affect water behavior.
Existing walls, slopes, planting areas and hardscape transitions are considered together when evaluating drainage and irrigation changes.
Hauling & Material Movement
Field work supported by the equipment needed to move the job forward.
Excavated material, imported fill and restoration materials can be coordinated as part of the sitework rather than treated as an afterthought.
ABD Photo Log
Field documentation from active and completed work.
This running log adds context beyond the featured portfolio—showing site conditions, staging, equipment, materials, infrastructure and design development as projects move from problem to solution.

Commercial • HOA • AOAO • Resort
Turn irrigation from a recurring problem into a managed system.
Large properties often lose water through a combination of hidden leaks, pressure problems, failed valves, poor zoning, controller settings and aging field infrastructure. ABD evaluates the system as a whole—not one broken head at a time.

How ABD Works
Diagnose first. Build second. Verify everything.
1
Inspect
Walk the property, gather history, verify current conditions and identify what needs to be measured—not assumed.
2
Test
Use pressure, flow, isolation, controller and field testing to separate symptoms from the actual failure point.
3
Scope
Build a practical repair plan with priorities, access considerations, restoration needs and clear project boundaries.
4
Execute & Verify
Complete the field work, test the repaired system, document performance and identify any remaining follow-up.

About Aquaponics By Design LLC
Practical field experience with a systems mindset.
ABD is a Maui-based contractor focused on the places where water systems and site conditions meet: irrigation, drainage, waterlines, excavation and landscape restoration.
Our approach is built around understanding how a system actually behaves in the field—pressure, flow, controls, elevation, soil, access and downstream conditions—before recommending the repair.
