Water Treatment
Pre-commissioning chemical cleaning is a strategic part of the building completion process, foreign debris will inevitably be found in newly fabricated mechanical pipework systems. If these are allowed to remain in the system this will ultimately cause blockage of such line items as commissioning and regulating valves, strainers etc. which in turn will affect the performance of heat or cooling emitters. There are several different areas of water treatment which Valco carry out.
Sectional flushing/cleaning can be carried out with the use of correctly sized temporary pumps. This is common in fit-out environments.
Microbiological fouling can cause lengthy delays to the commissioning process and can have a detrimental effect of the fundamental working condition of heating and chilled water systems.
A Bio-Cide wash can be carried out where closed loop systems have been microbiologically fouled. This procedure is necessary when system water has been allowed to be drained post pressure testing or allowed to sit within the system for a lengthy period of time without treatment. An alternative pressure test activity should always be considered.
Sample analysis of closed loop systems is a vital process in maintaining monitoring closed loop system performance.
All our pre-commissioning chemical cleaning of pipework systems is carried out in accordance with BSRIA Guide AG 1/2001.1.

Valco Services Ltd is able to provide a one stop water treatment solution using our own specialist resources and analysis by our own laboratory for all of the above processes.
Valco Services Ltd can provide sterilisation of all domestic and non-domestic water services.
This service can be provided as either a project delivery requirement, or as planned / reactive maintenance.
Analytical Legionella and Potable sample analysis form part of this sterilisation process in accordance with current BS6700 requirements.
Domestic Water Risk assessments can be carried by competent staff detailed records and drawing information are provided as per regulation.
Specialist consultation outlining water treatment pre-commissioning cleaning methodology and guidance is available from technical managers.
As a supplementary service we can offer ductwork analysis for cleanliness. We carry out analysis of the internal surface of the installed ductwork systems using a digital measuring system for determining the thickness of deposits and contamination that build up in steel ductwork.
From the results obtained we would be able to recommend whether there is a requirement for a duct cleaning programme.
