A PE-level technical course for senior plumbing engineers, drainage design managers, and BIM specialists covering the complete design of internal sanitary drainage systems in Abu Dhabi — in full compliance with UPC-AD and ADIPSDC. Participants learn to size drainage systems using DFUs, design venting and stack configurations, coordinate external tie-ins with TAQA Water Solutions, design private sewage disposal systems, and apply advanced hydraulic analysis and BIM integration to produce authority-approvable drainage designs for villas, residential, and commercial projects.

The Internal Drainage System Design – Abu Dhabi Industry Practice course provides a comprehensive technical framework for designing, coordinating, reviewing and verifying sanitary drainage systems within Abu Dhabi’s regulatory and construction environment.

| Why This Course Matters Internal drainage systems are fundamental to building sanitation and public-health protection. Their performance depends not only on selecting a pipe diameter, but on correctly coordinating fixture loads, slopes, velocities, venting, trap protection, cleanouts, invert levels and the final discharge route. Both under-design and over-design can create operational problems. Undersized systems can result in surcharge and backflow, while oversized drainage pipes may operate at insufficient velocity, allowing solids to settle and increasing the risk of blockage. Poor venting can lead to trap-seal loss, gurgling and sewer-gas migration, while incorrect building-sewer levels can make gravity discharge to the public network physically impossible. This course develops a complete lifecycle approach that connects regulatory interpretation, hydraulic design, authority coordination, digital modelling and site inspection so that compliant drawings translate into reliable installed systems. |
By the end of this course, participants will be able to:

Why Professionals Choose This Course
The course helps professionals understand internal drainage as an integrated hydraulic system, rather than a collection of independently sized pipes, enabling better coordination between regulation, calculations, construction and long-term performance. |

Establish the regulatory foundation governing internal drainage in Abu Dhabi. Examine UPC-AD and ADIPSDC applicability, DMT and TAQA Water Solutions responsibilities, internal-versus-external system boundaries, approval workflows and the circumstances in which public sewer connection or private sewage disposal requirements apply.
Translate plumbing fixtures into Drainage Fixture Unit loads and use accumulated DFUs to determine appropriate branch, stack and building-drain sizes. The module addresses under-design, over-design, pipe slopes, cleanouts and the relationship between code-compliant sizing and reliable hydraulic performance.
Design the pressure-balancing component of the sanitary drainage network. Participants examine trap-seal protection, individual and wet venting, relief vents, vent sizing, stack-pressure behaviour, vent termination and common deficiencies that lead to siphonage, backpressure, odour migration and authority comments.
Coordinate the transition from the internal drainage system to external sewer infrastructure. The module addresses building-sewer sizing, invert-level compatibility, gravity-discharge feasibility, backwater protection, lifting-station solutions and the parallel coordination required between DMT internal review and TAQA Water Solutions external connection approval.
Apply ADIPSDC requirements when no public sewer connection is available. Compare septic tanks, which provide primary treatment and discharge to an approved absorption system, with holding tanks used for temporary storage and pump-out, while addressing sizing, sludge allowance, retention time, setbacks, soil suitability, access and operational requirements.
Move beyond prescriptive sizing by evaluating how drainage systems actually perform under operating conditions. Apply flow validation, partial-flow analysis, Manning’s equation, self-cleansing velocity principles, stack-pressure analysis and risk mapping to identify oversized, poorly graded or hydraulically vulnerable sections and optimise the final system.
Integrate drainage engineering into a coordinated BIM environment by modelling pipe sizes, slopes and invert levels accurately, detecting multidisciplinary clashes and maintaining consistency between calculations, layouts and digital models. The module also addresses MePS and BINAA workflows and digital-quality checks before authority submission.
Bring design intent into construction reality through structured inspection and failure analysis. Participants examine reverse slopes, poor pipe bedding, missing vent connections, backflow, incorrect installation and other common defects, while learning how to document observations, assess impacts, identify root causes and specify corrective actions through professional snagging reports.
