Utility Security Services in California: Protecting Critical Infrastructure

Power, water, wastewater, energy, and other utility systems support daily life across California. These facilities may include substations, treatment plants, pumping stations, utility yards, storage areas, control buildings, reservoirs, equipment sites, and other critical assets.

For that reason, utility security requires more than placing a guard at a gate.

A strong physical security program can combine access control, trained security officers, patrols, video monitoring, reporting, dispatch, site-specific procedures, and coordination with facility management.

In addition, utility properties can vary greatly. A water treatment facility may have different access points and operating risks than an electrical substation or public works yard.

Therefore, effective utility security services in California should begin with the actual facility, its operating requirements, and its risk profile.

Why Utility Security Matters

California considers power plants, dams, communications systems, transportation systems, hospitals, and other essential facilities part of the state’s critical infrastructure.

The California Governor’s Office of Emergency Services Critical Infrastructure Protection program works with public and private infrastructure owners to identify risks, assess vulnerabilities, and improve resilience.

Utility facilities may need to consider risks such as:

• Unauthorized access
• Trespassing
• Theft
• Vandalism
• Copper and equipment theft
• Damage to fencing or gates
• After-hours activity
• Contractor access
• Remote facilities
• Workplace violence
• Suspicious activity
• Natural hazards
• Service disruptions

However, the exact risk level depends on the individual facility.

For that reason, security planning should start with a site assessment rather than a generic security package.

1. Start With a Utility Security Assessment

The first step is understanding the facility.

A security assessment may review:

• Property layout
• Main entrances
• Vehicle gates
• Employee entrances
• Contractor access
• Restricted areas
• Perimeter fencing
• Parking areas
• Remote equipment
• Control buildings
• Storage locations
• Existing cameras
• Alarm systems
• Previous incidents
• Emergency access routes

For example, a large water facility may have several remote buildings and equipment areas that cannot be continuously observed from one location.

As a result, the security plan may need to combine standing officers, mobile patrol, cameras, and digital checkpoints.

Cal OES also provides critical infrastructure risk and security assessment resources for infrastructure owners and operators.

2. Control Access to Utility Facilities

Access control is one of the most important parts of utility security.

Depending on the property, security personnel may support:

• Employee credential checks
• Contractor verification
• Vendor access
• Vehicle gates
• Visitor procedures
• Delivery access
• Restricted-area control
• Temporary credentials
• After-hours entry

For example, a contractor may be authorized to enter a maintenance area but not a control room.

Therefore, access permissions should reflect the person’s role and the facility’s procedures.

However, security officers should not create access policies during a shift.

Instead, utility management should define who is authorized to enter each area.

3. Protect Restricted and Sensitive Areas

Utility properties may contain areas that require tighter access control.

These may include:

• Control rooms
• Electrical rooms
• Chemical storage
• Pumping equipment
• Water treatment systems
• Communications rooms
• Equipment yards
• Fuel storage
• Maintenance shops
• Records areas

For that reason, officers should understand which areas are restricted and who is authorized to enter them.

In addition, post orders should explain what officers should do if they find an unsecured door, damaged lock, broken fence, or other access problem.

4. Perimeter Security

Many utility facilities have large perimeters.

Fencing, gates, barriers, lighting, cameras, and patrols can work together to support perimeter security.

Security personnel may inspect:

• Fence lines
• Vehicle gates
• Pedestrian gates
• Exterior doors
• Remote corners
• Utility roads
• Equipment yards
• Perimeter lighting

For example, a patrol officer may discover damaged fencing during an overnight inspection.

Then, the officer can document the condition and notify the appropriate facility contact.

As a result, management receives information before the issue remains unnoticed for an extended period.

5. Mobile Patrol for Large or Remote Utility Sites

Some utility properties cover large areas or include several separate facilities.

In those situations, mobile patrol services can extend security coverage.

Mobile patrol may support:

• Remote buildings
• Pump stations
• Equipment yards
• Parking areas
• Exterior gates
• Perimeter roads
• Storage areas
• Multiple utility sites

For example, one officer may remain at the main access point while mobile patrol checks remote locations.

This allows each officer to focus on a different part of the security operation.

6. Video Monitoring for Utility Properties

Video systems can provide additional visibility across remote or difficult-to-observe areas.

Depending on the property, cameras may cover:

• Gates
• Perimeters
• Equipment areas
• Parking lots
• Control-building entrances
• Storage yards
• Loading areas
• Remote facilities

However, cameras are most useful when there is a clear response procedure.

For example, monitoring personnel may review unusual activity and notify dispatch.

Next, an on-site officer or mobile patrol unit can respond when required by the facility’s procedures.

The U.S. Environmental Protection Agency provides physical security monitoring resources for water utilities that address monitoring, surveillance, communications, and response planning.

Secure Guard also provides video monitoring services.

7. Protect Water and Wastewater Facilities

Water and wastewater utilities face a wide range of physical security concerns.

EPA guidance emphasizes the importance of physical security, workforce protection, training, emergency response, monitoring, and coordination with first responders.

Potential areas of concern may include:

• Treatment plants
• Pumping stations
• Chemical storage
• Reservoir access
• Control buildings
• Utility yards
• Remote equipment
• Vehicle entrances

For example, a water facility may use controlled gates, surveillance, patrol routes, and restricted-area procedures together.

The EPA Water Sector Resilience Roadmap provides resources for strengthening water and wastewater security and resilience.

8. Protect Electrical and Energy Infrastructure

Electrical utilities may operate substations, control facilities, storage yards, maintenance facilities, and other infrastructure.

Security planning may focus on:

• Perimeter fencing
• Vehicle access
• Equipment areas
• Control buildings
• Contractor access
• Remote facilities
• After-hours activity

For example, substations may require strong perimeter controls because equipment is often located outdoors.

Mobile patrol and video monitoring can provide additional visibility where continuous standing coverage is not practical.

However, the security model should reflect the individual facility’s risk assessment.

9. Contractor and Vendor Access

Utilities often rely on outside contractors.

These may include:

• Maintenance contractors
• Engineers
• Equipment vendors
• Construction crews
• Delivery drivers
• Inspection teams
• Specialized technicians

Therefore, contractor access should be clearly managed.

Procedures may include:

• Approved contractor lists
• Identification checks
• Temporary credentials
• Vehicle logs
• Restricted-area permissions
• Check-in procedures
• Check-out procedures

Once these rules are established, officers can apply them consistently.

10. Protect Utility Equipment and Materials

Utility facilities may store valuable equipment, tools, wiring, fuel, replacement parts, and other materials.

Because of this, theft prevention may be an important security objective.

Security coverage may support:

• Storage-area patrols
• Vehicle gates
• Equipment yards
• Loading areas
• After-hours checks
• Video monitoring
• Incident reporting

For example, patrol officers can check material storage areas during overnight shifts.

In addition, cameras can provide visibility across areas that officers cannot continuously watch.

11. Copper and Metal Theft

Copper wiring, cables, and metal equipment can be valuable targets.

Utilities should identify areas where these materials are exposed or stored.

Security measures may include:

• Perimeter patrols
• Lighting
• Camera coverage
• Controlled gates
• Storage controls
• Randomized patrols
• Incident reporting

However, no security program can guarantee that theft will never occur.

Instead, the goal is to reduce unnecessary opportunities and identify problems quickly.

12. Security for Remote Facilities

Utility systems may include remote assets far from the primary facility.

These locations may receive less daily traffic and may be difficult to observe.

For that reason, remote facilities may benefit from:

• Video monitoring
• Scheduled patrols
• Randomized patrols
• Remote alarms
• Digital checkpoints
• Gate inspections
• Perimeter inspections

Mobile security can be especially useful when several sites need periodic inspection.

13. Incident Reporting

Utility security incidents should be clearly documented.

Reports may include:

• Date and time
• Exact location
• People involved
• Vehicle information
• Officer observations
• Actions taken
• Photos
• Notifications made
• Property damage
• Follow-up requirements

For example, an officer who finds a damaged fence can record the location, time, condition, photographs, and people notified.

As a result, facility managers receive a clear record of the issue.

14. Emergency Communication

Utility facilities may need security personnel to support emergency communication.

Depending on the situation, officers may:

• Contact dispatch
• Notify facility management
• Contact emergency responders
• Keep access routes clear
• Direct responders
• Secure restricted areas
• Document the incident

However, private security officers do not replace utility emergency teams, firefighters, police, or medical professionals.

Instead, officers should follow the facility’s approved emergency procedures.

15. Coordinate With First Responders

Utility facilities may need close coordination with police, fire, emergency management, and other public agencies.

EPA guidance for the water sector specifically encourages stronger relationships and information sharing with frontline emergency responders.

For that reason, security personnel should understand:

• Emergency entrances
• Site access routes
• Facility contact information
• Restricted locations
• Staging areas
• How to direct responders

In addition, post orders should define who has authority to provide emergency access.

16. Workplace Violence Prevention

Utility employees may work with contractors, customers, field crews, and members of the public.

Therefore, workplace violence planning can also be relevant.

California employers covered by Labor Code section 6401.9 must maintain a written Workplace Violence Prevention Plan.

Security personnel may support:

• Access control
• Visitor procedures
• Observation
• Incident reporting
• De-escalation
• Emergency communication

However, contract security does not replace the employer’s legal responsibilities.

California employers can review the Cal/OSHA Workplace Violence Prevention guidance.

17. Site-Specific Post Orders

Utility officers need clear written instructions.

Post orders may define:

• Access procedures
• Patrol routes
• Restricted areas
• Contractor procedures
• Vehicle gates
• Emergency contacts
• Reporting requirements
• Client notifications
• Escalation procedures

Without clear post orders, different officers may handle similar situations differently.

Therefore, instructions should reflect the individual utility facility.

18. Digital Patrol Verification

Utility properties may have large patrol areas.

For that reason, digital checkpoints can help verify required patrol activity.

Secure Guard uses SecureTrack to support field reporting and patrol accountability.

Depending on the service configuration, SecureTrack can support:

• Officer attendance
• GPS-supported patrol activity
• Security checkpoints
• Daily Activity Reports
• Incident reports
• Photos
• Digital post orders
• Supervisor visibility

As a result, authorized managers can gain better visibility into field security activity.

19. 24/7 Dispatch Support

Utility operations may continue around the clock.

Therefore, security personnel may need access to support during nights, weekends, and holidays.

Dispatch may help:

• Receive officer updates
• Contact supervisors
• Notify approved facility contacts
• Coordinate additional personnel
• Support incident escalation
• Document important communications

For example, an officer who finds an unsecured gate may notify dispatch.

Next, dispatch can contact the approved utility representative and field supervisor.

20. Active Field Supervision

Utility officers should also receive regular supervision.

Field supervisors may review:

• Officer attendance
• Post-order compliance
• Patrol completion
• Reporting quality
• Uniform standards
• Training needs
• Client concerns

In addition, supervisor visits can identify issues that may not appear in written reports.

Therefore, supervision remains an important part of a professional utility security program.

Utility Security Should Use a Layered Approach

No single security measure can address every risk at a utility facility.

Instead, a layered program may combine:

• Security officers
• Mobile patrol
• Access control
• Fencing
• Gates
• Lighting
• Cameras
• Video monitoring
• Alarms
• Digital checkpoints
• Dispatch
• Field supervision

For example, a water facility may keep an officer at the main entrance while cameras monitor remote areas.

Mobile patrol can then inspect equipment yards and perimeter locations.

As a result, several security layers support the same facility.

Utility Security by Facility Type

Water Treatment Facilities

Security may focus on entrances, chemical areas, equipment, restricted buildings, parking, and perimeter patrols.

Wastewater Treatment Facilities

Coverage may include gates, control buildings, equipment areas, contractor access, and remote infrastructure.

Electrical Substations

Security may focus on fencing, gates, equipment, perimeter visibility, and after-hours patrols.

Armed or Unarmed Utility Security?

Utility facilities do not automatically require armed personnel.

Many assignments may be well suited to professional unarmed officers.

These can include:

• Main entrances
• Contractor access
• Routine patrols
• Parking security
• Visitor management

On the other hand, higher-risk facilities may evaluate armed coverage when documented threats, asset exposure, previous serious incidents, or site conditions justify it.

Therefore, armed or unarmed staffing should be based on the risk assessment.

Questions to Ask a Utility Security Provider

Before choosing a provider, utility managers should ask:

• Will you conduct a site assessment?
• How are officers selected?
• Are officers properly licensed?
• Will post orders be site-specific?
• How are contractor entrances handled?
• How are patrols verified?
• Can you support remote facilities?
• Can mobile patrol cover multiple locations?
• Can officers work with existing cameras?
• What reports will management receive?
• Is dispatch available 24/7?
• How are officers supervised?
• What happens if an officer calls off?
• Can coverage change as facility conditions change?

A professional provider should be able to explain how the complete security operation will work.
