Types of Liquid Holding/Storage Tanks

1. Vertical Holding/Storage Tanks

Vertical Holding/Storage Tanks are available in a range of sizes from 1000 l – 25,000 l capacity.  These tanks are an increasingly popular alternative to traditional concrete in situ concrete pump stations, which require fitting out on site.

2. Horizontal Holding/Storage Tanks

Horizontal Holding/Storage Tanks are a great option for storing any liquids including abrasive liquids.  They are primarily used for sewage, wastewater and water storage so are ideal for rainwater harvesting, storing sewage/wastewater/process water and are also as firefighting tanks along as attenuation for surface water.

3. Steel Reinforced Portable Above/Below Ground Holding/Storage Tanks

BMS Steel Reinforced Holding/Storage Tanks can be placed above or partially/fully below ground without the need for a concrete surround.  They are an ideal solution especially when a temporary/emergency/semi-permanent liquid holding/storage solution is required e.g. storing sewage on site, as a mobile holding/storage tanks or as a mobile pump station portable solution is required.  BMS Steel Reinforced Pumps Stations can be moved from site to site on the back of a standard truck and have an expected lifespan of 25+ years.

4. Chemical Resistant Holding Tanks

BMS can provide custom coatings to its storage tanks are resistant to practically any abrasive liquid.  The tanks are suitable for many different applications and can be treated internally to endow chemical resistance to acids, alkalis (bases), oxidising agents and salts etc. if required. Please contact us to discuss your specific requirements.

BMS also manufacture a full range of very compact Chlorine Contact Tanks for potable water disinfection.


BMS Holding/Storage Tanks are completely pre-fabricated and delivered ‘ready to go’ so siteworks are minimal; placing the station in a suitably sized excavation, connecting the inlet/outlet pipes & electrical ducts.  BMS Holding/Storage Tanks only require a complete a 225 mm of lean mix concrete surround and an appropriate non-weight bearing slab on top to suit the loading.  The steel framed version does not require a concrete surround above/below ground.
