NAFDAC GMP-Compliant Factory Design Standard

1. The Logical Sequence (Unidirectional Flow)

This is the flow the inspector will trace on your map. It must be linear:

1. Entrance: Staff entry (via changing room).

2. Raw Water Storage: (External/Separated).

3. Treatment Area: (Matrixx RO + UV + Filtration).

4. Production/Filling Room: (The "Clean Room" – Air-conditioned, pressurized, UV-lit).

5. Finished Goods Store: (Cool, dry, dark).

6. Dispatch: (Separate exit).

1. 2. Visual Layout Specification (For CAD/Sketch)

   You can copy this structural arrangement into your drawing software (AutoCAD, SketchUp, or high-res graph paper):

3. Key Technical Annotations (Essential for Inspection)

Include these notes in the legend of your drawing so the inspector knows you are a professional:

• Flooring: "Non-shedding, epoxy-coated or ceramic tiled floors with coved edges for easy cleaning."

• Walls: "Smooth, washable, white/light-colored, fungus-resistant paint or tiles up to 2.5 meters."

Drainage: "Floor drains equipped with stainless steel grills and non-return traps to prevent pest entry."

Lighting: "Recessed or protected fluorescent/LED lighting (min 400 lux) with shatter-proof covers."

Airflow: "Production Room maintained at positive pressure; air-conditioned with HEPA-grade or standard filtration."

Cross-Contamination Prevention: "Unidirectional flow of personnel and materials; no back-flow."/

NAFDAC GMP 2026 Standards and global best practices for groundwater protection:

1. The Mandatory Minimum Distance

The minimum standard distance between a Septic Tank/Soak-away pit and your Borehole is 30 meters (approximately 100 feet).

• Why 30 Meters? This distance allows for "natural filtration." Soil acts as a filter, and 30 meters is the scientifically accepted safety buffer to ensure that seepage from the sewage system does not migrate 

• through the soil and contaminate the aquifer (your water source).

2. Critical Factors for the Site Survey

When you are on-site, you must also consider these three "Matrixx Standard" rules to ensure compliance:

• The Gradient Rule (Up-gradient vs. Down-gradient): Always place the borehole on the highest point of the land (up-gradient) and the septic tank on the lowest point (down-gradient). This ensures that gravity pulls any underground seepage away from your water source.

• The Depth Factor: In areas with high water tables (like parts of Lagos or coastal Ogun State), NAFDAC may demand even more distance or a deeper borehole casing (minimum 3 lengths of 304 Stainless Steel or heavy-duty PVC casing) to prevent surface water ingress. However, it's more reliable to use the most scientific and globally proven methodology which is to carry out geophysics investigation or survey to determine the right place for the acquiffer and use that as a support base to back your water test result from a standard laboratory to NAFDAC.

• Neighboring Risks: You must also check the distance of your borehole from your neighbor's septic tank. NAFDAC looks at the entire perimeter, not just your own compound.

• 3. Professional Advice for the ClientI

• If the site is too small to maintain the 30-meters gap, you have two options to remain compliant:

1. Relocate the Borehole: Move the water source to the extreme front of the property and the septic system to the extreme rear.

2. Water-Tight Septic Design: Use a fully "Water-Tight Concrete Tank" (not a traditional soak-away) that is evacuated by a vacuum truck, which reduces the risk of soil seepage.

Contamination Source	Minimum Safety Distance
Septic Tank / Soak-away	30 Meters (100 Ft)
Public Gutter / Drainage	10 Meters (33 Ft)
Cemetery / Abattoir / Fuel Dump	500 Meters (Local Regulation)
Underground Fuel Tank	50 Meters

 

1. QC Laboratory Setup (Mini-Lab)

NAFDAC requires an on-site laboratory to perform daily analysis of pH, Total Dissolved Solids (TDS), and Conductivity.

• Essential Equipment: Digital pH Meter, Digital TDS/Conductivity Meter, Reagent test kits (for residual chlorine/nitrites), Laboratory Logbook, 1x Stainless Steel Table, and 2x Shelves.

• Setup Cost: ₦450,000 – ₦700,000 (depending on brand accuracy and lab furniture quality).

• • Compliance Note: The lab must be a dedicated room or a clearly partitioned area within the Production/Office block, away from any chemicals.

  2. Distribution & Logistics (The "Last Mile" Strategy)

  

  
  

  In the Nigerian sachet market, distribution is 50% of the battle. You must advise your clients on the two most common "entry-level" tiers:

  • Tricycle (Keke Napep - Modified): Best for high-density residential areas and narrow streets.

  • • Item,Estimated Cost (₦)

    • QC Mini-Lab Setup,"600,000"

    • Logistics (Tricycle Starter),"1,500,000"

    • Matrixx Consultancy Fee,"2,500,000 (Median)"

    • TOTAL ADD-ON,"₦4,600,000"Cost: ₦1.2M – ₦1.8M (Brand new, custom-fitted with roof rack/cover for protection).

    • Capacity: 80–120 bags per trip.

  • Mini-Pickup (e.g., Suzuki Carry/Pick-up): Best for wholesale distribution to shops.

    • Cost: ₦4.5M – ₦7M (Depending on year/condition).

    • Capacity: 300–500 bags per trip.

  • Strategic Advice: "Start with one dedicated Tricycle for immediate

  •  

  • neighborhood supply to build brand loyalty, then scale to a Pickup once your wholesale volume hits 500 bags/day."

  3. Matrixx Nig Ltd Consultancy & Supervisory Fee

  This is your intellectual property fee. You are selling your expertise to guarantee they pass the NAFDAC audit.

  • Scope of Service: * Site selection/validation (Checking for hazards).

    • CAD blueprint creation + NAFDAC portal assistance.

    • • Vendor supervision (ensuring borehole drillers/builders follow your design).

      • Pre-Inspection Audit (The "Dry Run").

    • Professional Fee Range: ₦1,500,000 – ₦3,500,000 (or 5–8% of total project cost).

    • Negotiation Strategy: Always present this as a "Compliance Guarantee Fee." If they don't pay it, they risk failing NAFDAC, which costs them millions more in lost time.

    • Item	Estimated Cost (₦)
      QC Mini-Lab Setup	600,000
      Logistics (Tricycle Starter)	1,500,000
      Matrixx Consultancy Fee	2,500,000 (Median)
      TOTAL ADD-ON	₦4,600,000

N/B:"NAFDAC does not just inspect your machines; they inspect your workflow. If a worker carries a finished sachet back through the treatment area, your license will be rejected. This layout is designed so that the water moves in one straight, sterile line from the borehole to the delivery truck. By setting up with this 'Unidirectional Flow' now, we guarantee you pass the GMP audit on the very first visit. This is the Matrixx standard."
