State what the water is for and how each site receives it
A construction-supply tanker has to carry water within vehicle limits and deliver it at the quality and connection the site requires. Specify potable, non-potable or process-water service before selecting the tank and transfer equipment.
Include filling, travel, discharge, return and cleaning in the delivery cycle. A stainless shell or road-legal chassis alone cannot establish drinking-water suitability. Pumps, hoses, couplings, protected handling and prior service also matter to the wetted delivery path.
Match the water class, tank layout and receiving interface
The source and receiving connections determine part of the pump and hose duty. Baffles, vents, access and the completed mass belong in the same configuration review. A large nominal volume cannot establish either legal load or delivered volume per day.

| Decision | What to establish | Condition or limit |
|---|---|---|
| Water service | Define potable, non-potable or process-water duty and segregation. | A stainless tank alone does not certify drinking-water service. |
| Delivery cycle | Model fill, travel, discharge, return and cleaning time. | Tank volume does not determine daily delivered volume by itself. |
| Tank integration | Check material, baffles, venting, access and completed mass. | A shell capacity cannot override axle or chassis limits. |
| Interface | Match source and customer couplings, flow and contamination controls. | A pump rating does not prove compatibility with every site. |
A worked example: four deliveries in an 8-hour window
For this planning example, assume each trip delivers 8 m³ of water. Allow 20 minutes to fill, 30 minutes to reach the site, 20 minutes to discharge, 30 minutes to return and 20 minutes for the assumed queue and cleaning allowance. One cycle takes 120 minutes. An 8-hour operating window therefore fits four complete cycles: 4 × 8 = 32 m³ delivered.
These are hypothetical inputs, not a KEEYAK capacity or productivity claim. Replace them with the permitted load and measured times for the actual route. Deduct breaks, inspections and any other downtime from the available window. If queues or cleaning take longer, fewer complete trips will fit; tank volume alone does not establish daily supply.
Request the complete delivery and cleaning scope
Send daily quantities, source and site interfaces, delivery windows and required water class. WHO tanker guidance is a useful emergency-water planning reference, while local authorities and qualified designers determine the actual quality and acceptance requirements.
Information to prepare for this review
- Water class and source-quality responsibility
- Daily volume and delivery schedule
- Route, grade, road and access restrictions
- Fill and discharge connection details
- Pump, gravity, hose and metering duty
- Cleaning, inspection and destination requirements
Records to request and keep
- Water-service and route requirement brief
- Controlled tank, baffle and piping drawing
- Completed-vehicle mass and axle calculation
- Cleaning, functional-test and handover record
Common mistakes and what to check instead
- Calling every water tanker potable: Require material, cleaning, source, hose and local approval evidence for that service.
- Sizing from daily demand only: Build a real cycle from source to discharge and return.
- Leaving couplings to site adaptation: Approve each fill and delivery interface before fabrication.
Scope of this guide
This guide does not certify water quality, tank hygiene or destination legality.
Water authorities, qualified designers and the selected equipment documents remain controlling.
Stop filling or delivery for contamination risk, leakage, unsafe access, incompatible prior cargo or missing required inspection status.
Sources and applicability
Controls the project-input, quotation, approval and inspection workflow described in this guide.
Provides public checklists and worksheets; the signed project documents remain controlling.
Defines the relevant product family and published configuration boundaries. Project-specific ratings require the selected OEM documents.
