Pouch Water Project: Compact Sachet Filling Solution for a Rural Cooperative in Nigeria

In many rural regions of West Africa, safe drinking water is scarce and sachet (pouch) water is the most affordable way for families to access hygienic water. For a community cooperative, launching a local sachet water plant is not only a business opportunity but also a way to create jobs and improve public health.

This case study documents a compact sachet water project that zoolinked mechanical designed and delivered for a farming cooperative in northern Nigeria. Facing an unstable power grid, hard raw water and a tight budget, the cooperative needed a right-sized, robust pouch water line — here is how the solution was built.

Project Overview

Item	Detail
Location	Northern Nigeria (rural)
Product	500 ml sealed drinking water pouches (sachets)
Designed capacity	2,500 pouches per hour
Water source	Borehole (hard water)
Plant footprint	Approx. 90 m²
Operators required	2 per shift
Scope	Turnkey: design, manufacturing, installation, commissioning, training

1. Project Background & Client Requirements

A farming cooperative in northern Nigeria wanted to create local jobs and supply clean sachet water to surrounding villages, where reliance on untreated well water caused frequent waterborne illness.

The cooperative had a limited investment budget, an unreliable electricity grid, and high raw-water hardness from local boreholes. It also lacked trained technical staff, so the line had to be simple and durable.

The client set several clear requirements for the project:

• A tight investment budget requiring a cost-effective, right-sized line
• Robust equipment able to tolerate frequent grid voltage fluctuations
• Effective treatment for hard borehole water to protect equipment and taste
• Simple operation suitable for non-technical local operators
• Reliable output of around 2,500 sealed pouches per hour to serve nearby villages

2. Raw Water Analysis

Our engineers reviewed the borehole water report before finalizing the design. The water was potable in origin but showed high hardness and moderate mineral content, which drove specific treatment choices:

• Total hardness: high → water softener essential to protect RO membranes
• TDS: moderate → RO system for stable low-TDS purified water
• Iron/mineral traces: present → multi-media + carbon filtration upstream
• Microbial risk: possible → UV + ozone dual disinfection before filling

3. Turnkey Solution & Process Flow

zoolinked mechanical configured a compact packaged drinking water line optimized for reliability and low running cost. The full process flow is as follows:

1. Borehole water tank → feed pump
2. Multi-media (quartz sand) filter — removes suspended solids and turbidity
3. Activated carbon filter — removes odor, color and organic matter
4. Water softener — reduces high hardness to protect RO membranes
5. 5 µm security filter — final protection before RO
6. Reverse osmosis (RO) system — removes dissolved salts for stable low-TDS water
7. Purified water storage tank (SUS304)
8. UV sterilizer + ozone generator — dual disinfection
9. Single-lane automatic sachet filling & sealing machine — 2,500 pouches/hour
10. Date coding → manual-assisted packing for local distribution

4. Equipment Configuration

The equipment was selected for durability and low running cost under difficult grid conditions:

Equipment	Specification / Function
Multi-media filter	Removes turbidity & suspended solids
Activated carbon filter	Removes color, odor and organics
Water softener	Automatic resin softener for hard borehole water
RO system	Stable low-TDS purified water output
Purified water tank	SUS304 sanitary storage tank
UV + ozone disinfection	Dual sterilization barrier
Automatic sachet machine	Single-lane form-fill-seal, 2,500 pouches/hour
Voltage stabilizer	Protects equipment during grid voltage swings

5. Installation & Commissioning

After factory testing, the equipment was shipped and installed within the cooperative’s 90 m² building. Installation and commissioning were completed in about two and a half weeks, including:

• Positioning the water treatment skid, softener and RO system
• Integrating a voltage stabilizer to guard against grid fluctuations
• Setting up the storage tank, UV and ozone disinfection
• Installing and calibrating the single-lane sachet machine
• Trial runs with water testing to confirm compliance with drinking water standards

6. Operator Training

Since the cooperative members had no prior technical experience, thorough hands-on training was provided. Operators were trained on:

• Daily start-up, shutdown and cleaning routines
• Monitoring softener regeneration and RO performance
• Operating the sachet machine and adjusting seal and fill settings
• Basic maintenance and troubleshooting to minimize downtime

7. Results & Return on Investment

After commissioning and training, the line delivered a stable 2,500 sealed pouches per hour and now supplies clean, affordable water to surrounding communities:

• Stable output: 2,500 pouches/hour with 2 operators per shift
• Reliable operation despite grid fluctuations, thanks to voltage stabilization
• Water quality consistently met local drinking water standards
• Several new local jobs created within the cooperative

The affordable running cost and strong village demand allowed the cooperative to operate profitably and sustainably, reinvesting proceeds back into the community.

Conclusion

This Nigeria cooperative project demonstrates how a compact, robust sachet water line can succeed even under challenging conditions — unstable power, hard water and a limited budget. By matching the design to real site constraints and providing thorough training, zoolinked mechanical delivered a turnkey solution that created jobs and improved access to safe drinking water.
