Planning a Summer Shutdown? Essential Drainage, Environmental and Infrastructure Projects to Complete Before Operations Resume

For many industrial facilities, manufacturing plants, logistics hubs and commercial sites, summer shutdowns provide a rare opportunity to carry out maintenance, inspections and rehabilitation works without disrupting day-to-day operations.

While production lines slow down and site activity reduces, facilities teams have a valuable window to assess critical infrastructure, address known issues and complete projects that would otherwise be difficult to undertake during normal operations.

For Facilities Managers, EHS Managers, Engineering Managers and Site Managers, a well-planned shutdown can help reduce risk, improve compliance and prevent costly failures later in the year.

Why Summer Shutdowns Are the Ideal Time for Infrastructure Maintenance

During normal operations, maintenance work often competes with production demands, vehicle movements, staff access requirements and operational priorities.

A planned shutdown creates several advantages:

Reduced disruption to operations
Easier access to key infrastructure
Improved site safety
Greater flexibility for contractors
Opportunity to complete larger projects
Reduced risk of unexpected downtime after restart

Rather than waiting for failures to occur, shutdown periods allow organisations to take a proactive approach to asset management.

What Maintenance Should Be Completed During a Planned Shutdown?

Every site is different, but there are several areas that are commonly overlooked until problems arise.

CCTV Drain Surveys

Many drainage systems remain hidden underground for decades with little understanding of their condition.

A CCTV drain survey can identify:

Structural defects
Root ingress
Cracks and fractures
Blockages
Collapsed sections
Infiltration and leakage

Understanding the condition of your drainage network before operations resume can help prevent unexpected failures and emergency call-outs.

Drain Rehabilitation and No-Dig Repairs

If defects are identified, a shutdown period is often the perfect time to carry out rehabilitation works.

Modern trenchless technologies can often restore drainage systems without excavation, reducing disruption and preserving surrounding infrastructure.

Common rehabilitation solutions include:

Drain lining
Patch repairs
Junction repairs
Manhole rehabilitation
Structural drain repairs

These techniques can significantly extend the lifespan of ageing drainage assets while avoiding the cost and disruption associated with traditional excavation.

Remote Entry and Robotic Inspections

Health and safety remain a major priority for both Facilities Managers and EHS professionals.

Advances in remote-entry technology now allow many inspections to be completed without personnel entering confined spaces.

Robotic inspection systems can be used to assess:

Drains and sewers
Tanks
Pipelines
Chambers
Difficult-to-access infrastructure

Reducing confined space entry wherever possible can improve safety while providing high-quality inspection data.

Drone Surveys

Drones are becoming an increasingly valuable tool for industrial asset inspections.

They can safely inspect:

Roofs
Tanks
Silos
Culverts
Lagoons
Structures
Large industrial sites

Drone technology allows facilities teams to gather detailed information quickly while reducing the risks associated with working at height.

Interceptor and Tank Maintenance

Interceptors, separators and storage tanks often operate quietly in the background until they become a problem.

A shutdown period provides an excellent opportunity to carry out:

Interceptor cleaning
Tank cleaning
Asset inspections
Condition assessments
Capacity reviews

These activities can help reduce environmental risks and support ongoing compliance obligations.

Environmental Compliance Reviews

For EHS Managers, shutdown periods can also provide an opportunity to review environmental controls and compliance systems.

Areas commonly assessed include:

Surface water drainage systems
Pollution prevention measures
Monitoring infrastructure
Environmental assets
Site drainage records
Maintenance documentation

Proactive reviews can help identify gaps before they become regulatory issues.

Why Waiting Until Operations Resume Can Be Costly

One of the most common challenges facilities teams face is balancing maintenance requirements with operational pressures.

Unfortunately, issues that are postponed during a shutdown often return at the worst possible time.

The consequences can include:

Emergency call-outs
Production disruption
Flooding incidents
Environmental pollution events
Increased maintenance costs
Unplanned downtime
Health and safety concerns

A relatively small investment in planned inspections and maintenance can often prevent significantly higher costs later.

Questions Every Facilities and EHS Manager Should Ask Before a Shutdown

Before finalising shutdown plans, consider the following:

Do we know the condition of our drainage network?
Have any recurring drainage issues been fully investigated?
Are there ageing assets that may require rehabilitation?
Could remote-entry technology reduce confined space risks?
Have our interceptors and tanks been inspected recently?
Are there opportunities to complete repairs with minimal disruption?
Are all environmental assets operating as intended?
Do we have accurate records of underground infrastructure?

These questions can help prioritise maintenance activities and ensure shutdown periods deliver maximum value.

Making the Most of Your Shutdown Window

The most successful shutdown programmes are those that focus on prevention rather than reaction.

By combining CCTV surveys, robotic inspections, drone technology, drain rehabilitation and environmental asset assessments, organisations can gain a clearer understanding of their infrastructure while addressing issues before they impact operations.

Whether you’re planning a factory shutdown, site maintenance programme or annual infrastructure review, the weeks before operations restart can provide an invaluable opportunity to strengthen asset performance, improve compliance and reduce future risk.
