Booster Set Services

Water booster pumps are an essential component in the delivery of water at usable pressures to high rise commercial, public sector and residential properties.

Water booster pumps are an essential component in the delivery of water at usable pressures to high rise commercial, public sector and residential properties. Your water authority supplied water mains pressure will normally only supply water at usable pressures (Ofwat requirement is 15 psi) up to the third floor.

High rise buildings of three or more storeys usually have water supplied into a common cold water storage tank, typically installed in basement areas, from which it is delivered to individual outlets and dwellings through water booster pumps.

A water booster pump set is sized in accordance with water demand and numbers of storeys or required pressure head. Typically multi-pump systems are designed with a degree of redundancy in a duty standby configuration to ensure continuity of water supply in the event of pump failure. Single and multi-pump systems should be periodically maintained in order to mitigate the risk and inconvenience of interrupted water supply.

New and up-rated systems required as a result of reduction in mains water pressure

Until recently many water authorities have delivered water in excess of the legislated minimum pressure as set by Ofwat. Many water authorities are now operating a programme of actively reducing water pressure in order to reduce water leakage while meeting the minimum legislated delivery pressure. As a result, many properties of 3 or more storeys that are currently serviced directly by water mains will require water booster sets in the future.

As an independent service provider, SES works with all the major water booster pump manufacturers for service, refurbishment and replacement. This enables us to consistently recommend the best solution for all applications. In the event that your property is affected by mains water pressure reductions, we are able to recommend, supply and install the best solution.

CompEx Certified

The CompEx Scheme is the recognised global scheme for the protection of workers anywhere that explosive atmospheres exist. The CompEx Scheme provides competency validation of individuals across a range of disciplines and different hazards to help create a safer workplace.

EUSR national water hygiene card holders

The National Water Hygiene (‘Blue Card’) scheme plays a vital part in ensuring the protection of public health and promoting safe drinking water practices. Originally developed in 2006, this scheme replaced the many different water company specific hygiene training programmes and courses, removing the need for individuals to undergo separate testing, health screening and the carrying of multiple cards.

Construction Skills Certification Scheme

CSCS cards provide proof that individuals working on construction sites have the appropriate training and qualifications for the job they do on site. By ensuring the workforce are appropriately qualified the card plays its part in improving standards and safety on UK construction sites.
