New Construction System Startup & Commissioning
The decisions made during system startup set the trajectory for equipment life, efficiency, and water quality for years to come. RW Water Services ensures your new systems are commissioned correctly from day one.
Getting Startup Right Protects Your Investment for Decades
New mechanical systems — cooling towers, chilled water loops, condenser water systems, steam boilers, and domestic water distribution — are at their most vulnerable during the construction and commissioning phase. Construction debris, mill scale, welding flux, and pipe dope contaminate systems before they ever reach steady-state operation. Without proper flushing, cleaning, and chemical startup, this contamination becomes embedded in the system and drives corrosion, fouling, and equipment failures that persist for the life of the building.
RW Water Services works directly with mechanical contractors, commissioning agents, and facility owners during the construction phase to ensure water systems are properly cleaned, flushed, passivated, and chemically started before handover. We coordinate our work with the project schedule so that startup treatment is completed in sequence with equipment commissioning — not as an afterthought.
Our startup programs are fully documented, providing the owner with a complete record of pre-commissioning flushing, chemical treatment, water analysis results, and system baseline data. This documentation supports equipment warranties, commissioning reports, and the ongoing water treatment program that follows handover.
What Sets Our Startup Programs Apart
Early Project Involvement
We engage during the design and construction phase — not just at startup — to review specifications, identify treatment requirements, and coordinate with the mechanical contractor before systems are filled.
Coordinated with Your Schedule
Startup treatment is sequenced with equipment commissioning, balancing, and owner training so that water treatment never holds up the project schedule or certificate of occupancy.
Thorough Pre-Commissioning Flushing
High-velocity flushing programs remove construction debris, mill scale, and contamination from piping systems before chemical treatment begins — protecting pumps, valves, and heat exchangers from abrasive damage.
System Passivation
Controlled passivation programs establish a stable protective oxide layer on metal surfaces during the critical early operating period, preventing the aggressive early corrosion that shortens equipment life.
Baseline Water Analysis
Comprehensive water analysis at startup establishes baseline chemistry data for all systems, providing a reference point for ongoing treatment optimization and warranty compliance.
Complete Handover Documentation
Full startup reports including flushing logs, chemical dosing records, water analysis results, and passivation data — ready for the commissioning report, O&M manual, and equipment warranty files.
Startup & Commissioning Services We Provide
Pre-Commissioning System Flushing
High-velocity flushing of chilled water, condenser water, heating hot water, and domestic water systems to remove construction contamination before chemical treatment and equipment startup.
Cooling Tower Startup Treatment
Chemical startup and passivation for new and replacement cooling tower systems, including initial fill chemistry, blowdown management, and biological control program establishment.
Closed Loop System Startup
Chemical treatment startup for chilled water, heating hot water, and condenser water closed-loop systems — inhibitor loading, pH adjustment, and system baseline establishment.
Boiler & Steam System Startup
Boilout, chemical cleaning, and startup treatment for new steam boilers and condensate return systems to remove manufacturing residues and establish proper boiler water chemistry.
Domestic Water System Disinfection
Chlorination and flushing of new domestic water distribution systems per AWWA and applicable code requirements prior to occupancy.
Startup Documentation & Reporting
Complete startup reports covering all water systems — flushing logs, chemical records, water analysis, and passivation data — formatted for commissioning reports and O&M manuals.
