Drainage for Inset Bases
Prevent Water Accumulation at the Base
Controlled Removal of Water
Inset lighting installations can require effective drainage to prevent water accumulation around the light base and associated cable connections.
Drainage accessories can be incorporated into the base arrangement to support controlled removal of water and help maintain a suitable installation environment.
Coordinate With
- Inset base construction, including the base manufacturer's approval before any drain hole is added to or any modification is made to a certified light base
- Pavement structure and its drainage layers, so the outlet does not saturate the pavement base
- Surrounding ground conditions
- Cable entry arrangements
- Drainage outlet or soakaway arrangement
- Local water-management requirements
Junction Pit Drainage
Safer, More Practical Access
Underground Connections
Junction pits provide access to underground AGL cable connections and therefore require appropriate consideration of water management.
Coordination
A suitable arrangement can help reduce standing water within the pit and support safer and more practical access for inspection and maintenance.
Provisions should be coordinated with the pit construction, installation depth, surrounding soil conditions and available drainage route.
Handhole Drainage
Where Water Could Accumulate
Drainage Provisions
Handholes can also require drainage provisions where groundwater, surface water or other environmental conditions could result in water accumulation.
Function and Protection
The arrangement should maintain the intended function of the handhole while protecting cable connections and allowing continued maintenance access.
Equipment Base Drainage
Keep Water Away from Critical Interfaces
Controlled Drainage
AGL equipment bases may require controlled drainage depending on their construction, location and exposure to water.
Design Intent
Provisions should be designed so that water does not remain around critical electrical or mechanical interfaces and does not compromise the surrounding foundation.
Flow Characteristics
Performance Depends on the Whole Arrangement
Selection Should Consider
- Expected water volume
- Ground permeability
- Drainage outlet arrangement
- Installation depth
- Water table conditions
- Surrounding pavement and foundation construction
- Potential for sediment or debris accumulation
Drainage Route
Performance depends on the type and configuration of the accessory, surrounding ground conditions and available discharge route.
The route should be designed to avoid creating new water-retention points within the airfield lighting infrastructure.
Do not discharge into foul or sanitary drains. Where the outlet joins a storm-drainage system, prevent backflow into the base or pit when the drain is full.
Material & Environmental Conditions
Matched to the Installation Environment
Exposure
Drainage components may be exposed to moisture, soil contact, temperature variation and other environmental conditions.
Material Selection
Material should be appropriate for the intended environment and compatible with the surrounding base, pit or infrastructure.
Where components are installed underground, long-term resistance to the expected conditions should be considered during product selection.
Installation Method
Confirm Before Installation
- Type of AGL equipment or infrastructure
- Drainage requirement
- Installation location
- Required drainage capacity
- Installation depth
- Surrounding soil and ground conditions
- Available discharge route
- Cable and equipment interfaces
- Maintenance access requirements
- Applicable project requirements
Drainage accessories should be installed as part of the approved civil and electrical infrastructure arrangement. The final arrangement should prevent obstruction of cable routes, electrical connections and access points.
Drainage & Cable Infrastructure
Continuous, Maintainable Underground Installation
Underground Cable Infrastructure
Effective drainage is particularly important around underground cable infrastructure where water accumulation can complicate inspection, maintenance and cable connection work.
Arrangements should be coordinated with cable ducts, junction pits, handholes and cable protection systems.
Cable Connections
Where cable joints, connectors or other electrical interfaces are located within underground infrastructure, drainage provisions should be considered alongside the connection arrangement.
The objective is to minimise unnecessary water accumulation while maintaining appropriate protection and accessibility for maintenance.
Installation Considerations
Review as Part of the Overall Installation
Consider
- Pavement drainage
- Groundwater conditions
- Soil permeability
- Surface-water flow
- Drainage outlet location
- Installation depth
- Sediment and debris
- Accessibility for inspection
- Interface with existing drainage infrastructure
Not an Isolated Component
Drainage performance can be affected by surrounding civil works and ground conditions.
Arrangements should be reviewed as part of the overall airfield lighting installation rather than treated as an isolated component.
Inspection & Maintenance
Include Drainage in Routine Inspection
Inspection Considerations
- Drainage openings
- Evidence of standing water
- Blockages or sediment
- Physical damage
- Drainage flow
- Condition of surrounding infrastructure
- Water ingress into pits or bases
- Accessibility of drainage components
Corrective Action
Blocked or damaged drainage components should be cleaned, repaired or replaced as appropriate.
Standing water in bases and pits is a common cause of low insulation resistance and earth faults on series circuits. Where insulation-resistance readings fall, check drainage along with the cable and connectors.
Replacement & Rehabilitation
Correct Drainage Deficiencies During Rehabilitation
Assess First
Drainage accessories can be used during rehabilitation where existing bases, pits or underground infrastructure have drainage deficiencies.
Before modification, the existing drainage route, ground conditions and surrounding infrastructure should be assessed.
Coordinated Upgrade
Upgrading drainage can be coordinated with replacement of inset bases, junction pits, handholes and associated cable infrastructure.

FAQ
AGL Drainage Accessories — Frequently Asked Questions
What are AGL drainage accessories and why does drainage matter?
Drainage accessories help protect AGL foundations, pits, bases and underground cable installations from standing water and the maintenance problems that come with it. Properly selected accessories support water management around airfield lighting infrastructure and help keep installations accessible and serviceable. They can be selected according to the installation type, the surrounding ground conditions, the water-management requirements and the associated AGL infrastructure.
Where are drainage accessories used?
They are used with inset bases, junction pits, handholes and equipment bases, and around underground cable infrastructure such as ducts, pits and cable routes. They also serve lighting foundations, runway and taxiway installations, areas needing controlled water drainage, and both new installations and rehabilitation projects.
How is drainage arranged for inset light bases?
Inset installations can need drainage to prevent water collecting around the light base and its cable connections. Drainage accessories can be built into the base arrangement to support controlled removal of water. Coordinate with the inset base construction, including the base manufacturer’s approval before any drain hole is added to or any modification is made to a certified light base. Also coordinate with the pavement structure and its drainage layers so the outlet does not saturate the pavement base, and with the ground conditions, cable entries, the outlet or soakaway arrangement and local water-management requirements.
How is drainage handled in junction pits and handholes?
Junction pits give access to underground cable connections, and a suitable drainage arrangement can reduce standing water in the pit and make inspection and maintenance safer and more practical. Handholes can also need drainage where groundwater or surface water collects. In both cases the provision should be coordinated with the pit or handhole construction, installation depth, soil conditions and available drainage route, and it should protect the cable connections while keeping maintenance access.
What affects how well a drainage arrangement performs?
Performance depends on the whole arrangement, not only the accessory. Selection should consider the expected water volume, ground permeability, the outlet arrangement, installation depth, water table conditions, the surrounding pavement and foundation construction, and the potential for sediment or debris to build up. The discharge route should be designed so that it does not create new water-retention points within the airfield lighting infrastructure.
Where should the drainage outlet discharge?
The available discharge route must be confirmed before installation. Do not discharge into foul or sanitary drains. Where the outlet joins a storm-drainage system, prevent backflow into the base or pit when the drain is full. Drainage should be reviewed as part of the overall airfield lighting installation, together with pavement drainage, groundwater, soil permeability, surface-water flow and the interface with existing drainage infrastructure.
How does standing water affect AGL series circuits?
Standing water in bases and pits is a common cause of low insulation resistance and earth faults on series circuits. Where insulation-resistance readings fall, check the drainage along with the cable and connectors. Water accumulation in underground infrastructure also complicates inspection, maintenance and cable connection work.
What should be confirmed before installing drainage accessories?
Confirm the type of AGL equipment or infrastructure, the drainage requirement, installation location, required drainage capacity, installation depth, surrounding soil and ground conditions, the available discharge route, cable and equipment interfaces, maintenance access requirements and applicable project requirements. Material should suit the environment, including moisture, soil contact and temperature variation. The accessories should be installed as part of the approved civil and electrical arrangement without obstructing cable routes, electrical connections or access points.
How should drainage components be inspected and maintained?
Include drainage in routine inspection. Check the drainage openings, evidence of standing water, blockages or sediment, physical damage, drainage flow, the condition of the surrounding infrastructure, water ingress into pits or bases and the accessibility of the drainage components. Blocked or damaged components should be cleaned, repaired or replaced as appropriate.
Can drainage accessories be added during rehabilitation?
Yes. They can be used during rehabilitation where existing bases, pits or underground infrastructure have drainage deficiencies. Before any modification, assess the existing drainage route, ground conditions and surrounding infrastructure. A drainage upgrade can be coordinated with replacement of inset bases, junction pits, handholes and associated cable infrastructure.
Which references apply to AGL drainage?
Relevant references include FAA AC 150/5340-30J on design and installation details for airport visual aids, FAA AC 150/5370-10 (Items L-110 and L-115 for ducts and junction structures), FAA AC 150/5320-5D on airport drainage design for the surrounding pavement and storm-drainage system, and ICAO Doc 9157 Part 5 on electrical systems, along with the applicable civil, electrical, pavement and project requirements.
