The problem

Bacteria in drinking water are a health risk, especially in well water after flooding or when the well is in poor condition.

Our solution

We identify the cause, then install a UV unit and pre-filter where needed. We also offer disinfection of the water system.

Price

Price depends on water quality, required capacity and installation scope. We prepare an exact quote after a water analysis or site details.

Service area

We are based in Tartu County (Rehepapi põik 3, Soinaste küla, Kambja vald) and mainly serve Tartu and Harju counties – Tartu, Tallinn and the surrounding areas. We also travel to sites anywhere in Estonia.

Frequently asked questions: Microbiologically contaminated water

How can I find out whether my well water contains bacteria?

The presence of bacteria can only be confirmed by a laboratory analysis (e.g. E. coli, coliform bacteria, enterococci). Water can be clear and odourless even when it is contaminated.

How does a UV unit disinfect water?

A UV unit irradiates the flowing water with ultraviolet light, which damages the DNA of microorganisms and prevents them from multiplying. The method adds no chemicals to the water and does not change its taste.

Is a pre-filter needed before a UV unit?

Usually, yes. Turbidity, iron and sediment reduce the effect of UV radiation, so a mechanical filter and, where needed, iron removal are installed before the UV unit.

What should I do after a flood or well contamination?

Do not drink the water before it has been analysed. The well and water system must be cleaned and disinfected, and the water then analysed again. UV disinfection provides lasting protection.
