Engineering Overview

Qatar Approved Engineering

Clean water delivery and efficient wastewater removal are foundational to health and sanitation. BANAN International provides comprehensive public health engineering services across Qatar, fully compliant with Kahramaa water regulations and Ashghal drainage network standards.

We design and execute complete domestic water supply distribution, central hot water heating systems with solar integration, pressure booster pump stations, acoustic soil and waste drainage piping, rainwater and stormwater collection, wastewater treatment plants (WWTP/STP), water filtration, UV disinfection, and underground grease/sand interceptors.

Scope of Works & Deliverables

Every project is delivered as a complete turnkey solution executed by certified in-house engineering teams:

Domestic Potable Water Supply Networks (PPR, PEX, HDPE, Copper, Stainless Steel)

Variable Speed Booster & Water Transfer Pumping Stations

Gravity & Vacuum Soil, Waste, and Vent Drainage Systems

Stormwater Attenuation, Soakaways & Rainwater Pumping Systems

Water Treatment: Filtration, Reverse Osmosis (RO), Water Softeners & UV Systems

Grease Traps, Oil/Water Separators & Ashghal Drainage Connection Permits

Our 5-Step Project Execution Lifecycle

We maintain structured quality gates from initial design calculations to final authority handover:

Fixture Unit Calculations & Pump Sizing

Calculating total fixture units (FU), peak water demand (L/s), drainage slopes, and pump head pressure.

Ashghal & Kahramaa Design Approvals

Submitting plumbing riser diagrams, external drainage connections, and grease trap sizing for permits.

Pipework Installation & Acoustic Insulation

Rigid installation of water supply and drainage networks with thermal and acoustic wrapping.

Hydrostatic Pressure & Smoke Testing

Hydrostatic pressure testing of supply lines up to 10-15 bar and smoke/air testing of drainage stacks.

Sterilization, Chlorination & Handover

Chemical disinfection and chlorination of water tanks and pipelines with certified lab water test reports.

Key Advantages & Assurance

Certified fusion-welded PPR and electrofusion HDPE piping guaranteeing zero leakages

Constant water pressure across all building floors with intelligent VFD booster skids

Low-noise acoustic drainage pipes eliminating water flow sounds in luxury and commercial spaces

Full compliance with Kahramaa Water Quality Standards and Ashghal environmental codes

Codes, Standards & Authority Compliance

Strict adherence to Qatar statutory regulations and international engineering guidelines:

Kahramaa Water Installation Regulations

Ashghal (Public Works Authority) Drainage Design Manual

BS EN 12056 Gravity Drainage Systems Inside Buildings

IPC (International Plumbing Code) & UPC Standards

Frequently Asked Questions

Why is pipeline chlorination and water testing mandatory before handover in Qatar?

Kahramaa requires all new domestic water tanks and pipework to undergo chemical disinfection and pass biological laboratory testing to prove the water is 100% safe for human consumption before permanent connection.

How do you prevent unpleasant odors from drainage stacks?
