01Service schedule

Twelve service lines. One accountable team.

Most clients come to us for a single item on this list — a risk assessment, a cooling tower, a failed sample — and keep us because the rest of the water estate can sit with the same provider.

03Record of practice

Built on research. Grown by word of mouth.

1981: The researchFounder Rob White was a key member of the research team that identified the first chemical biocides to be effective against Legionella pneumophila in industrial cooling systems.
Early 1990s: The shiftWith real-world experience behind him and global awareness of legionella rising, Rob saw an impending shift in the industry towards water hygiene services for the control of microorganisms — a relatively untapped area of the market.
1995: Waterline, later WhitewaterWaterline was created to provide those services, later becoming Whitewater. Since then the company has thrived organically on high-quality water management for legionella control and industrial water treatment.
Today: Over 25 years of tradingA field service operation with a qualified, experienced and pragmatic team delivering a high-quality service across the UK.

04How we work

Compliance that holds up when somebody asks to see it.

Duty holders don't need more paperwork. They need a water estate that is genuinely under control, and records that prove it.

iSurveyed before it is scoped: We walk the site and read the existing records before anything is quoted, so the scheme matches your asset register rather than a standard package resized to fit.
iiOur own engineers on site: Directly employed field staff allocated to named sites. The person who carries out the task is the person who signs the record, and they come back next visit.
iiiAnalysis in our own laboratory: Samples go to our UKAS accredited laboratory, so the evidence behind every entry in the logbook holds up when an auditor or a regulator asks to see it.
ivFindings raised the day we find them: Out-of-specification results, failing plant and unworkable schemes are reported immediately with a costed option — not bundled into a quarterly summary.

05Where we work
