Project Delivery Pathway



Involves project analysis, design and drawing, and client review.

During the Discover stage, we focus on gaining a comprehensive understanding of your liquid management project. This stage consists of the following steps: 

Project Analysis: Our team conducts a thorough analysis of your project requirements, considering factors such as liquid type, volume, storage needs, and regulatory compliance. We carefully assess site conditions, operational objectives, and any specific challenges related to your industry sector. 

Design & Drawings: Based on the project analysis, our experienced professionals develop custom designs and detailed drawings that align with your specific liquid management needs. We ensure that the design is fit-for-purpose, safe, and compliant with industry standards. 

Client Review: Collaboration with our clients is crucial to delivering successful projects. During the client review phase, we present the design and drawings for feedback and suggestions. We take the time to address any concerns and make necessary adjustments, ensuring the design meets your operational requirements and expectations. 



Consists of engineering, client sign-off, and manufacture of the agreed solution.

In the Develop Stage, we focus on realizing the approved design into a practical and functional liquid management solution. This stage consists of the following steps: 

Engineering: Our team of skilled engineers and technicians meticulously convert the approved design into a comprehensive engineering plan. We consider all technical aspects, including structural integrity, fluid dynamics, and safety requirements, ensuring a robust, reliable, and standard-compliant liquid management system. 

Client Sign-Off: Before the team starts manufacturing your product, we first seek your formal sign-off on the engineering plan. This ensures that you are fully satisfied with the proposed liquid management solution and gives us authorization to proceed to the next stage. 

Manufacture: Using advanced manufacturing techniques and high-quality materials, we initiate the fabrication process. Our state-of-the-art facilities and skilled craftsmen ensure that every component is manufactured to the highest level of industry standards, guaranteeing durability and longevity. We also manufacture your projects in-house to ensure we have control over every aspect of the product manufacturing process from start to finish.  



Consists of quality assurance, product delivery, and documentation.

The Deliver Stage focuses on the finalisation, quality assurance, and delivery of the liquid management project. This stage consists of the following steps: 

Quality Assurance: We prioritise quality control throughout the project. Before the final handover, we conduct extensive inspections and tests to ensure that the liquid management system functions as intended, adheres to industry standards, and meets all regulatory requirements. 

Delivery: Once the quality assurance checks are successfully completed, we proceed with the delivery of the liquid management system. Our experienced professionals handle the delivery process with our specialised delivery fleet efficiently and with minimal disruption to your operations. We also make sure to assemble the necessary accessories and fittings to ensure everything is already prepared upon installation and to reduce downtime costs.  

Documentation: As part of our commitment to transparency and knowledge transfer, we make sure to provide comprehensive documentation related to the liquid management project. This includes operation manuals, maintenance guidelines, warranties, and any necessary certifications.
