Regular Maintenance

Why Regular Maintenance Matters

Flood resilience systems can be affected by weather, debris, corrosion, wear, obstruction, building changes, landscaping, forgotten storage locations and missing records.

A flood barrier that cannot be accessed, a drain covered with leaves, a pump alarm nobody receives or a backflow device with no inspection record may not perform as expected when conditions worsen.

Maintenance Helps Confirm

• Flood protection equipment is accessible
• Drainage points are clear and visible
• Pumps, alarms and controls are being serviced
• Backflow prevention records are available where relevant
• Flood barrier parts, seals and fixings are not missing or damaged
• Responsible people know what needs to be checked
• Issues are recorded and followed up

The goal is not to create busywork. The goal is to keep important flood controls ready, visible and reviewable.

For a broader checklist across flood resilience areas, see Flood Resilience Checklists.

What Should Be Checked

Maintenance checks should reflect the flood controls and site conditions at the property. A house with doorway barriers may need a different routine from a strata building with basement ramps, pumps, drains and shared plant rooms.

The practical starting point is to list the systems, openings and areas that affect flood resilience, then assign a check or review process to each one.

Common Items To Include

• Flood barriers, posts, panels, seals, fixings and storage locations
• Doorways, garage entries, driveway entries and basement ramp openings
• Drainage pits, grates, trench drains and surface water flow paths
• Pump and sump systems, including controls and alarms
• Backflow prevention devices, where present
• Low vents, service penetrations and wall openings
• Plant rooms, lift pits, electrical rooms and other sensitive areas
• Flood risk documentation and emergency contact records

Keep The Check Practical

A useful maintenance routine should be specific enough to guide action, but simple enough that it can be repeated consistently.

For barrier-specific checks, see Flood Barrier Options For Property Owners. For residential and commercial use cases, see the Residential Flood Barrier Guide and Commercial Flood Barrier Guide.

Maintenance Frequency And Review Triggers

Maintenance timing should suit the property, flood exposure and installed systems. Some items may need scheduled servicing by contractors, while others may need visual checks before or after heavy rain.

Rather than relying only on a calendar, property owners and managers should also consider trigger events that should prompt an additional review.

Common Review Triggers

• Before the wet season or local storm season
• Before a forecast severe weather event, where safe and practical
• After heavy rain, flooding or a near miss
• After building, paving, landscaping or drainage changes
• After flood barrier installation, servicing or repair
• After pump, alarm or electrical faults
• When responsible people, managers or contractors change
• Before insurance renewal or internal risk reviews, where records are being prepared

Maintenance Should Be Planned, Not Remembered

Add inspection dates, contractor servicing, record reviews and follow-up actions to a calendar, maintenance system or action register so important checks are not missed.

Assigning Maintenance Responsibility

Flood maintenance should have a clear owner. If responsibility is unclear, small issues can remain unresolved until the system is needed.

Responsibilities may sit with a property owner, building manager, strata manager, facilities manager, committee, tenant, contractor or site operator depending on the property type and arrangement.

Responsibility Questions

• Who checks the flood barriers?
• Who arranges drainage cleaning or inspection?
• Who arranges pump servicing and alarm testing?
• Who keeps the maintenance records?
• Who follows up defects or recommendations?
• Who updates emergency contacts?
• Who briefs new managers, tenants, committee members or contractors?

Avoid Single-Person Dependency

Maintenance routines should not depend entirely on one person remembering every detail. Records, calendars, contractor contacts and procedures should be stored somewhere accessible to authorised people who need them.

For shared building responsibility and action registers, see the Strata Flood Planning Guide.

Maintenance Records And Follow-Up Actions

Maintenance records help show what was checked, what was found, what was fixed and what still needs action. They are useful for future reviews, contractor handovers, strata meetings, insurance discussions and post-event investigations.

A record is most useful when it includes enough detail for someone else to understand the issue without needing the full conversation repeated.

Maintenance Records Should Show

• Date of inspection, service or review
• Area, system or item checked
• Person, contractor or company completing the check
• Issues identified
• Photos taken, where useful
• Actions completed
• Actions still required
• Responsible person or contractor for follow-up
• Target date or next review date

Follow-Up Matters

Finding an issue is only useful if someone follows it through. Maintenance records should make outstanding actions visible until they are completed or formally reviewed.

For a more detailed record-keeping structure, see the Flood Risk Documentation Checklist. For insurance-related record preparation, see Flood Mitigation And Insurance Resilience.

Warning Signs That Need Action

Warning signs should be treated as prompts for review. They may not mean a system has failed, but they can show that something needs cleaning, servicing, repair or specialist assessment.

Warning Signs To Record

• Flood barrier parts are missing, damaged or hard to access
• Seals, channels, posts or fixings appear damaged
• Drainage grates are blocked or repeatedly covered with debris
• Water ponds near openings after rain
• Pump alarms activate or fault lights appear
• Sump pits contain heavy debris, silt or unusual material
• Backflow prevention devices have no current inspection record
• Emergency contacts, manuals or records are missing or outdated
• Previous maintenance recommendations have not been actioned

Escalate Technical Issues

Technical issues involving pumps, electrical systems, drainage capacity, backflow devices, structural fixings or barrier performance should be reviewed by suitable contractors or qualified professionals.

For more detail on these systems, see Drainage Management, Pumps And Sump Systems and Backflow Prevention.

Regular Maintenance Checklist

Use this checklist as a starting point when setting up or reviewing a flood maintenance routine.

Summary

Regular maintenance helps keep flood resilience systems ready, visible and easier to review.

A useful routine should include scheduled checks, event-based reviews, assigned responsibilities, contractor servicing, maintenance records and follow-up actions.

The practical aim is simple: know what needs checking, know who is responsible and keep records showing what has been done.
