Autodesk Inventor Mechanical Design Drawings — Biwater Water Treatment
A complete set of fabrication-ready mechanical design drawings for a large-scale seawater desalination plant serving the British Virgin Islands. All drawings were developed in Autodesk Inventor using client specifications and P&ID documents. The system processes seawater through six Reverse Osmosis trains — removing salt, purifying for drinking, and cycling through backwash and clean-in-place subsystems.
A complete set of drawings created in Autodesk Inventor using client specifications and P&IDs. The 1st Pass Reverse Osmosis System is where seawater passes through six RO trains to remove salt and purify water for drinking, before moving to the 2nd Pass system for further treatment.
The 1st Pass Reverse Osmosis System is the primary desalination stage where seawater passes through six RO trains to remove salt and purify the water for drinking. After this stage the treated water moves on to the 2nd Pass system for further treatment and polishing.
The 2nd Pass Reverse Osmosis System receives the final treated water from the 1st Pass RO system and applies an additional purification stage to achieve drinking water quality standards. The polished water is then sent to the chemical treatment system for final conditioning and distribution.
PVC Schedule 80 piping throughout. The backwash tank receives Reject/Brine from the Reverse Osmosis trains. This brine is discharged to the Polishing Filters (Astra Filters) via the Cartridge filters, then fed back into the main six RO trains for re-filtration — maximizing water recovery efficiency.
The CIP or Clean-In-Place system is used to flush the plant with various cleaning and chemical agents to maintain membrane performance and system hygiene. Cleaning cycles are performed at allocated intervals based on plant specifications. The following drawings represent the complete fabrication set for this subsystem.
Standard general arrangement detail sheets covering piping, fittings, support structures, and common assembly references used across all systems within the British Virgin Islands desalination plant. These details form the shared reference baseline for the full drawing set.
