Bespoke Underground Tank Design For Demanding Applications

  • EN13067

There are occasions when a standard off-the-shelf underground tank will suffice but there are also many occasions when it is simply not sophisticated enough. NIPLAST®’s response to such occasions is our SAFESUB®  range of underground tanks, developed to meet the more onerous challenges many of our customers face routinely.

Product Specification


Product Specification

SAFESUB® tanks are designed to accommodate the internal liquid loads of the contained liquids, together with the external soil and pedestrian loads and are perfect for spillage, interceptor and blind tank projects. SAFESUB® tanks feature holding down arrangements and an installation procedure to withstand local water table floatation forces. Polypropylene and high-density polyethylene materials of construction mean that SAFESUB® tanks can store a wide range of chemicals, effluents, waste streams, rainwater and more.

The SAFESUB® tank is available as a single tank only or is also available in our SAFEWALL® format featuring an integral bunding cavity. Extended access manways complete with grip handles and lockable lids are a feature as are outlet connections complete with internal dip pipes for road tanker evacuation. In line with NIPLAST®’s  other leading products, SAFESUB® is designed to BSEN12573–3:2000 and crafted by welding technicians accredited to EN13067. Bespoke SAFESUB® design can optimise available footprint or minimise excavation depths through our flexible manufacturing facilities.

Bespoke Underground Storage Tanks

Bespoke underground storage tanks, also referred to as custom underground storage tanks, are individually tailored solutions crafted to fulfil specific storage needs across diverse substances and industries. These tanks are intricately designed to cater to distinct requirements, offering a versatile and effective storage solution that optimises space usage and ensures adherence to regulatory standards.

Unlike standardised storage options, bespoke underground storage tanks are fashioned from the ground up, taking into account factors such as size, shape, material, and intended contents. These tanks can be fashioned to fit within the available space, whether it’s a restricted urban locale or an expansive industrial site. They serve various sectors, including agriculture, manufacturing, petrochemicals, and more. While bespoke water storage tanks are popular, Niplast’s tanks can be used to store a variety of liquids.

Underground Tanks

Our tanks are manufactured to accommodate a wide spectrum of materials, encompassing liquids, chemicals, fuels, and even water. The customised design of our under ground tanks ensures seamless integration with pre-existing infrastructure, such as piping systems and additional equipment.

Safety and compliance remain paramount in our storage tank solutions, and bespoke underground tanks are no exception. The tanks are engineered to meet rigorous regulatory standards and guidelines, guaranteeing the secure storage of substances while minimising environmental risks. Furthermore, these tanks can be equipped with advanced features such as leak detection systems, corrosion-resistant coatings, and access points for simplified maintenance.

The creation of bespoke underground tanks entails meticulous planning, engineering expertise, and a profound comprehension of specific storage requirements. Seeking advice from professionals specialising in storage solutions is essential to ensure that the tank is structured to withstand the test of time, changing conditions, and the demands of the stored contents which can range from water (water tanks) to waste.

In a world where available space often poses constraints and storage needs diverge widely, bespoke our underground storage tanks present a personalised approach to efficient, secure, and compliant storage. Their versatility, tailor-made configuration, and emphasis on safety make them valuable assets for industries seeking dependable and customised storage solutions.

This material flexibility ensures that SAFESUB® tanks are fit for purpose, regardless of the substance they need to contain.

SAFESUB® tanks go beyond being mere containers; they are meticulously designed to endure both internal and external loads. Whether it’s the loads from the contained liquids, external soil, or pedestrian activity, these tanks are engineered to maintain their structural integrity. The tanks designed offer both a durable and cost-effective solution.
