​Experts in Water Treatment & Legionella Control
At DeltaFlow Water Solutions, we specialise in scale prevention, corrosion protection, and Legionella control for commercial and industrial sites across the UK. From cooling towers and steam boilers to closed-loop water systems, our qualified engineers deliver bespoke treatment programmes and compliance-led solutions. We offer turnkey services, site-specific risk assessments, and practical on-site training to keep your water systems safe, efficient, and fully compliant with BS2486, BG29, BG50, HSG274, and ACoP L8 standards.
Our Expertise
Advanced Solutions
Cooling Tower Treatment
Legionella risk assessments, chemical dosing (scale/corrosion inhibitors, biocides), system monitoring (conductivity, pH, ORP), cleaning, disinfection, and side-stream filtration.
Compliance support with logbooks, audits, and 24/7 emergency call-outs.
UK-wide coverage with customised programs.
Steam Boiler Treatment
Feedwater treatment (softening, RO, filtration), chemical dosing (oxygen scavengers, alkalinity/phosphate control), blowdown optimisation, and condensate line treatment.
​
Regular testing (TDS, pH, conductivity, etc.) and trend analysis.
Closed System Services
Pre-Commission Cleaning (BSRIA BG29): System surveys, dynamic flushing, biocide dosing, passivation, and certification for new builds/refurbishments.
​​
Monitoring & Maintenance (BSRIA BG50): Routine sampling, chemical dosing, and system health reports to prevent issues like magnetite sludge, corrosion, and microbial growth.
Customised Compliance Solutions
We design service plans tailored to your specific water chemistry, system metallurgy, and operational needs. Our electronic compliance system provides transparent reporting, water hygiene logbooks, and audit preparation, ensuring full compliance with UK regulations. With flexible scheduling and 24/7 emergency support, we minimise administrative burdens and keep your systems running smoothly.
Specialist Training
Our on-site training programmes empower your team with practical knowledge in water treatment, Legionella control, and system maintenance. Tailored to your plant and aligned with industry standards (BS2486, HSG274, BG29/BG50), our training includes hands-on demonstrations, compliance guidance, and attendance certificates for boiler operators, facility managers, and maintenance teams.
