Water, drainage, and fire services - the hydraulic systems you design are invisible until they fail. When your designs don't perform, Professional Indemnity insurance protects you from costly remediation claims.

Hidden Systems

Hydraulic services are buried in walls, under floors, and underground. When they fail - flooding, backups, inadequate supply - the damage and disruption can be extensive, and your design documentation becomes the focus of investigation.

Fire Services Exposure

Fire sprinkler and hydrant hydraulic design carries life-safety liability. If your fire services calculations prove inadequate during an actual fire event, the professional exposure is significant. It's worth reviewing your PI cover limits against the scale of fire services work you take on.

WHY TANK INSURANCE

What to look for in PI cover

Hydraulic engineering spans multiple building systems. We work with specialist underwriters who understand how hydraulic consulting risk is categorised, and we take the time to understand your practice before approaching the market.

Building construction representing hydraulic engineer professional liability

01

Specialist Market Access

We access insurers who cover hydraulic services - water supply, sanitary drainage, stormwater, fire services, and gas. Getting the scope of cover right matters when claims arise.

02

Fire Services Cover

Fire sprinkler hydraulic design carries life-safety implications. We work with you to understand the scale of your fire services work and source terms that reflect it.

03

Remediation Claims

Hydraulic system failures often require extensive remediation - excavation, pipe replacement, flood damage repair. We discuss your project profile to help identify appropriate cover limits.

04

Project Requirements

Developers and head contractors require hydraulic engineers to hold PI cover. Your policy should meet contractual specifications and provide certificates when needed.

PROFESSIONAL RISKS

Risks Hydraulic Engineers Face

These hydraulic design decisions carry professional liability when systems fail to perform or cause damage to property.

Water supply design inadequate for building requirements
Drainage system failures causing flooding or backups
Fire sprinkler hydraulic calculations proving insufficient
Hot water system design not meeting peak demand
Stormwater management causing property flooding
Sanitary system blockages from incorrect grading
Gas reticulation design non-compliance with standards
Backflow prevention failures causing contamination

QUESTIONS

Frequently Asked Questions

Hydraulic engineer PI insurance covers claims arising from your professional advice and design services for water supply, drainage, fire services, gas, and stormwater systems. If your hydraulic design causes system failures or non-compliance, PI insurance protects you from liability claims.
Yes. Hydraulic engineers provide design and advisory services - they don't install systems. PI cover responds to claims arising from design errors and professional advice, not installation workmanship. Plumbers who also provide design services generally need PI cover in addition to their trade insurance.
Common claims include water supply systems that don't achieve required pressures or flows, drainage designs that cause backups or flooding, fire sprinkler hydraulics that fail performance testing, and stormwater designs that cause property flooding during storm events. Our PI FAQs for engineers covers how these claims typically unfold.
Cover limits vary depending on the scale and nature of your projects. Fire services design carries higher exposure given life-safety implications, and larger commercial or residential developments may require higher limits. We work with you to understand your project profile and source terms that reflect your actual exposure.
Fire sprinkler and fire hydrant hydraulic design is the type of work PI insurance is designed to respond to. Given the life-safety nature of fire services, your cover limits are worth reviewing against the scale of projects you work on. Each policy has its own terms, so it's worth checking your wording carefully.
