Ensuring Clean Water Systems
SAS Water deliver specialist water treatment services to maintain water quality and protect the efficiency and lifespan of closed heating and cooling systems. Effective water treatment supports corrosion prevention and scale prevention, helping prevent microbiological contamination which can damage plant and reduce operational efficiency.
Our services focus on closed system analysis and water quality monitoring to ensure systems are maintained in accordance with recognised industry guidance, including heating system treatment and cooling system water treatment programmes.
Is It For You?
Water treatment services are required wherever closed systems rely on controlled water quality to operate efficiently.
You may require closed system analysis if you need:
- Water quality testing within heating or chilled water systems
- Identification of corrosion, scale or biological contamination
- Verification of chemical treatment and inhibitor levels
- Support maintaining system efficiency and plant protection
- Advice on maintaining water quality in line with industry best practice

Pre-Commission Cleaning
Pre-commission cleaning ensures that new or modified water systems are free from debris, sediment, and microbial contamination before use.
Cleaning and disinfection are carried out to safeguard water quality and ensure safe system operation.
How The Process Works
- System Inspection: Review of new or modified pipework and components.
- Flushing & Cleaning: Removal of sediment, biofilm, and debris from the system.
- Disinfection: Application of approved treatments to eliminate bacterial risks.
- Verification Sampling: System confirmed clean and compliant prior to commissioning.
Compliance Standards
Pre-commission cleaning supports guidance for:
- BSRIA BG29/2021
- BS 8552:2012
Closed System Analysis
Closed system analysis involves testing and monitoring water quality within heating and cooling systems to maintain efficiency and lifespan and prevent internal damage.
Ongoing analysis helps identify early signs of corrosion, scale, and contamination before they impact system efficiency.
How The Process Works
- Sample Collection: Water samples taken from representative system points.
- Field/Laboratory Testing: Water quality is tested against recognised guidance parameters, including microbiological analysis for TVCs, Pseudomonads, SRBs, and NRBs to assess system condition.
- Condition Assessment: Identification of corrosion, scale, or system imbalance.
- Treatment Review: Evaluation of existing chemical dosing and protection levels.
- Recommendations: Corrective actions provided to maintain system performance.
Compliance Standards
Closed system analysis supports guidance set out in:
- BSRIA BG50/2021
- BS 8552:2012
Boiler Water Treatment
Boiler water treatment prevents scale, corrosion, and microbial contamination, safeguarding equipment efficiency and lifespan.
How The Process Works
- System Review: Evaluate water quality and boiler performance.
- Treatment Application: Chemical treatment applied to control corrosion and scale.
- Monitoring & Adjustment: Ensure ongoing water quality and system efficiency.
- Servicing & Documentation: Annual checks and reports maintained for compliance.
Compliance Standards
Boiler water treatment supports guidance for:
- BSRIA BG50/2021
- BS 2486:1997
Remedial Work: Water Treatment Solutions
Remedial works address water treatment issues across closed systems and boiler water treatment, ensuring safe and compliant operation.
How The Process Works
- System Assessment: Review of system performance and identification of water quality issues.
- Remedial Action: Corrective measures applied to restore system safety and efficiency.
- Monitoring & Verification: Ensuring water quality and system performance meet required standards.
- Documentation – Records provided for compliance and audit purposes.
Compliance Standards
Remedial work supports guidance for:
- BSRIA BG50/2021

We Manage Water From A To Z
Water Hygiene
Our water hygiene programmes focus on controlling the conditions that allow Legionella bacteria to develop within building water systems. Through routine inspections, temperature checks, outlet testing, and documented control measures, we help organisations maintain safe water systems and protect building occupants. These preventative measures support regulatory compliance while ensuring water safety procedures remain consistent and fully documented.
Water Treatment
Closed heating and cooling systems require careful chemical management to maintain performance and prevent internal damage. Our treatment programmes include system analysis, inhibitor dosing, and ongoing condition monitoring to control corrosion, scale formation, and microbiological contamination. Maintaining balanced water chemistry protects mechanical infrastructure while supporting long-term operational efficiency.
Water Regulation Compliance
Backflow prevention is a legal requirement under the Water Supply (Water Fittings) Regulations 1999, ensuring that contaminated water cannot enter the public mains supply. SAS Water provides specialist installation, inspection, and servicing of WRAS-approved Reduced Pressure Zone (RPZ) valves, helping organisations maintain safe potable water supplies and meet regulatory obligations.
