Designing Industrial Water Treatment Facilities
In this article, Paul Martin, Hexagon PPM, discusses the challenges of designing and maintaining water treatment facilities.
The design and construction of new greenfield water facilities, particularly waste water treatment plants, require significant capital investment, and typically are joint-venture projects, involving the combined effort and contribution of many different specialists, contractors, suppliers, stakeholders, the owner, operators, regulatory authorities and, the general-public. They require extensive planning, co-operation and co-ordination between all parties involved, with major projects taking several years to design, permit, construct and commission, before coming on-stream.
Today, due to the complexity of projects undertaken – and this applies also to the rehabilitation and extension of existing brownfield facilities – but depending on the project scope, a water treatment plant engineering design team will normally consist of a core group of civil engineers. The engineers utilize the expertise and resources of a multi-discipline group of architects and structural, electrical, mechanical and process engineers to execute the design1
.
Aging facilities As facilities age, and new technology advances, to make the facility work more efficiently and economically, owners face the challenge of how to upgrade the existing facility without disrupting water supply and quality. Faced with an obligation to ensure that the plant and processes employed adhere to ever stricter and constantly changing regulations, and due to advances in technology introduced and refined over the last half century, many plants in existence today would benefit from modernization.
Water treatment facilities don’t just exist on-land; many ships have mini-water treatment or de-salination plants on- board. These need to be maintained and serviced regularly, with this usually performed when the vessel is moored at a port. Limited turnaround time is available to make modifications, meaning efficient techniques need to be employed by on-board engineering teams to ensure the vessel can remain operational at sea. Furthermore, new legislation concerning the treatment and disposal of ballast water

activities, water facility plant owners, are looking at how they can improve the quality of the information they hold for their facility. Supporting the handover of intelligent information for completely new or revamped facilities, and stipulated by governments, Building Information Modelling (BIM) is a project execution methodology now commonly applied to civil engineering projects. BIM helps all stakeholders consistently define and share information throughout the whole project lifecycle, and ensures a high-quality intelligent information (data and documentation) handover for the asset is eventually provided to the facility owner, which the operator can then use throughout the lifecycle to operate and maintain the facility.

at sea, mean many marine vessels require modification to ensure they comply.
How software solutions can help Fortunately, Hexagon PPM offers several solutions supporting the design, construction and commissioning of new greenfield, or the revamp and upgrade of existing brownfield water facilities, both on-shore and off-shore. The CADWorx® family of products – working on either AutoCAD® or BricsCAD® - is one such solution - possessing an extensive and unique range of tools and capabilities that make designing multi-discipline water treatment facilities fast, accurate and cost-effective. CADWorx can meet the engineering and design challenges contractors face and project execution methodology followed to layout, design and deliver all types of water treatment facilities.
Improving Asset Management Wanting to improve asset management, operational processes and maintenance
Fortunately, CADWorx’ ability to exchange designs in Industry Foundation Classes (IFC 2x3) format and optionally working on BricsCAD (BIM), a buildingSMART- compliant CAD platform, means it can seamlessly play its role in BIM projects.
If the facility owner is looking for a way to improve their asset information in the absence of a project, or wishes to create documentation for their water facility due to records being inaccurate or out of date, or in some instances, missing completely from their archive, point clouds captured by laser scanning the facility, used in combination with CAD, provide a way to reverse engineer the plant. The point cloud can be used either to create a 3D model, from which various types of drawing can be produced, or alternatively, to create 2D drawings directly from it. Point clouds are also useful for familiarizing and training new personnel in how the facility works, and for planning future change.
CADWorx working in conjunction with Leica CloudWorx provides an excellent solution here. CADWorx can be used to create an as-built model consisting of piping, equipment and structure, and from this produce layout and isometric drawings, or to provide an as-built design basis supporting plant modification. If a 3D model isn’t required, CloudWorx can be used to create 2D drawings from the point cloud.
