Standards we work towards

Water Testing Standards 


When conducting water tests and samples and as we do, supplying water (clean or quality assured drinking water), we work to standards set out by the British Standards Institution and other bodies who issue guidelines on handling and storage of water.

For example, did you know that we train our water tanker drivers in the safest method of extracting water from the network using hydrants and standpipes, to prevent damage to pipework and stirring up sediment in the line which could get into the water being drawn to fill a tanker.

Take a look at our training video. The procedure is called water calming and forms an important part of the chain of events involved in getting water to you in pristine condition.


The BSI standards we work to are:


BS8551:2015 Provision and Management of Temporary Water Supplies and Distribution Networks


These guidelines are intended to provide advice where there is a need to provide a temporary supply of water for domestic purposes for drinking, washing, cooking, central heating and sanitary purposes, such as water supplied to construction sites and events and festivals, where it is the responsibility of site managers and event organisers to ensure a wholesome and sufficient supply for any temporary installation.

The standard states that a wholesome supply is defined in the Water Quality Regulations and the Private Water Supplies Regulations, as one that does not contain any microorganism or parasite, or any substance at a concentration or value that could constitute a potential danger to human health.


BS8558:2015 Guide to the design, installation, testing and maintenance of services supplying water for domestic use within buildings and their curtilages. Complementary guidance to BS EN 806


This standard was developed for anyone involved in the design, installation, testing, operation and maintenance of hot and cold water services for domestic use in buildings.

The standard also provides advice for the water supply services industry on all aspects of sampling and monitoring of hold and cot water services.

Any standards published by the British Standard are tried and tested rules which governs methods, processes and tests. Working to such standards ensures conformity in all aspects of how we work with water.


Asides from the above British Standards, we work towards or our water technicians are accredited in the below:


ACOP L8: Legionnaire’s Disease. The Control of Legionella bacteria in water systems. Approved Code of Practice.


HSG274 Legionnaire’s Disease Technical Guidance.


City and Guilds Accredited Control of Legionella in Hot & Cold Water Systems.


This City and Guilds accredited course is designed to enable effective management of hot and cold water systems in accordance with the ACOP L8: Legionnaire’s Disease Approved Code of Practice and HSG274 Technical Guidance. Our water technicians have completed this course.


EUSR National Water Hygiene ‘Blue Card’


The EUSR National Water Hygiene card is considered crucial in ensuring the protection of public health and promoting safe drinking water practices. The aim of the scheme is to provide an understanding of the need for good hygiene when working with potable water. Our water technicians and water tanker drivers hold the National Water Hygiene card accordingly.


WRAS Approved Products


All the products and equipment we use when supplying drinking water supplies or vessels are WRAS (Water Regulations Advisory Scheme) approved.
