Firewater & Spill Containment Systems
During a fire or major spill, contaminated firewater can rapidly overwhelm site drainage, pollute watercourses, and trigger regulatory enforcement. High‑risk industrial sites — including chemical plants, fuel storage depots, manufacturing facilities, utilities, and COMAH establishments — require firewater containment systems that activate instantly, isolate flow paths, and prevent uncontrolled releases.
Arthian provides firewater and spill containment systems designed to work in harmony with bunds, drainage networks, penstock valves, interceptors, and emergency response procedures. Our engineers deliver systems that meet regulatory expectations, withstand real‑world incident conditions, and provide clear evidence of compliance.
Why Firewater & Spill Containment Matters
Firewater is often contaminated with chemicals, hydrocarbons, foam, and debris. Without effective containment, it can cause significant environmental harm and long‑term remediation liabilities. Regulators expect dutyholders to demonstrate that firewater and spill containment systems are robust, tested, and integrated into site emergency plans.
Arthian’s containment systems ensure:
- Controlled isolation of contaminated firewater
- Prevention of uncontrolled releases to drains, watercourses, or soil
- Integration with bunds and secondary containment infrastructure
- Compliance with environmental protection guidance and COMAH expectations
- Clear operational procedures for emergency response teams
Our Firewater & Spill Containment Capabilities
We design systems that capture, isolate, and store contaminated firewater during emergency events. This includes:
- Firewater retention basins and lagoons
- Containment tanks and temporary storage systems
- Automated isolation systems
- Flow diversion and emergency routing
- Capacity modelling for worst‑case scenarios
Our designs ensure firewater is safely contained until it can be treated or removed.
Spill containment systems must respond instantly to accidental releases. Arthian engineers:
- Spill isolation valves
- Emergency shut‑off systems
- Containment channels and diversion routes
- Interceptors and treatment units
- High‑risk area containment strategies
These systems minimise environmental impact and support rapid incident response.
Penstock valves are central to firewater and spill containment. We design and specify:
- Manual and automated penstock valves
- Remote‑operated isolation systems
- Fail‑safe emergency closure mechanisms
- Integration with bund drainage networks
Penstocks ensure contaminated water remains on site during an incident.
Firewater containment systems must integrate seamlessly with site drainage. We provide:
- Drainage mapping and flow modelling
- Isolation strategy development
- Sump and pump‑out design
- Oil‑water separator integration
- Emergency flow diversion routes
This ensures contaminated water is captured, not discharged.
Firewater events can generate large volumes of contaminated water. We model:
- Worst‑case firewater volumes
- Foam expansion and runoff
- Multi‑tank or multi‑area scenarios
- Freeboard and emergency storage capacity
Our modelling supports COMAH safety reports and emergency planning.
Containment systems must align with emergency response procedures. We support:
- Firewater containment plans
- Spill response protocols
- Training for site teams
- Integration with fire service requirements
- Testing and validation exercises

Frequently Asked Questions
Can you assess bund capacity and containment compliance?
Yes—our surveys include bund volume modelling and containment strategy assessments aligned with COMAH containment policy and CIRIA C736.
Can you help with bund compliance and containment strategy?
Absolutely. We assess bund capacity, permeability, and structural integrity, and model containment scenarios aligned with COMAH containment policy.
Do you assess bund integrity and capacity?
Yes—we offer bund permeability testing, capacity modelling, and structural appraisal aligned with CIRIA C736 and COMAH containment policy.
