Bunsil Water Supply Project.  
Bunsil Station, Siassi – Tewae Siassi District 

This report outlines the successful completion and commissioning of the Bunsil Water Supply Project, delivered within a period of one (1) month in preparation for the 35th Lutheran Church National Synod.
The project involved the design, fabrication, and erection of a 20,000-litre (20kL) elevated steel tank reservoir system, constructed to ensure reliable water storage and distribution to Bunsil Station township and Synod facilities. The system effectively served delegates and visitors during the 35th Lutheran Synod event and continues to provide sustainable water supply services to the Bunsil Station community today. 

CONSTRUCTION COMPLETION REPORT


Bunsil Water Supply Project

Location: Bunsil Station, Siassi – Tewae Siassi District

Project Capacity: 20,000 Litres (20kL) Elevated Reservoir System

Implementation Period: One (1) Month

Implementing Agency: ApproTech Solutions PNG


1. Executive Summary

This report outlines the successful completion and commissioning of the Bunsil Water Supply Project, delivered within a period of one (1) month in preparation for the 35th Lutheran Church National Synod.

The project involved the design, fabrication, and erection of a 20,000-litre (20kL) elevated steel tank reservoir system, constructed to ensure reliable water storage and distribution to Bunsil Station township and Synod facilities.

The system effectively served delegates and visitors during the 35th Lutheran Synod event and continues to provide sustainable water supply services to the Bunsil Station community today.


2. Project Background

Bunsil Station was selected to host the 35th Lutheran Synod national gathering. However, the existing water supply infrastructure was inadequate to support the large influx of delegates, church leaders, and visitors expected for the event.

To address this urgent need, ApproTech Solutions PNG mobilized technical personnel, materials, and equipment to implement a rapid but structurally sound water supply solution within a compressed timeframe.


3. Project Scope of Works

The following works were executed:

3.1 Civil Works

  • Site clearing and preparation
  • Construction of reinforced concrete foundation pads
  • Anchor bolt installation for structural stability

3.2 Structural Works

  • Fabrication and erection of the elevated steel tank support structure
  • Installation of cross-bracing for lateral stability
  • Installation of the access ladder and safety platform

3.3 Reservoir Installation

  • Installation of 20,000-litre (20kL) modular water storage tank
  • Secure mounting and connection to distribution lines
  • Overflow, scour, and outlet fittings installed

3.4 Pipeline & Distribution

  • Connection to the source supply
  • Installation of reticulation lines
  • Testing of pressure and flow distribution


4.  Technical Specifications

Component Specification

  • Reservoir Capacity: 20,000 Litres (20kL)
  • Tank Type: Modular Panel Tank
  • Support Structure: Fabricated Mild Steel Frame
  • Foundation: Reinforced Concrete Footings
  • Distribution: Gravity-fed reticulation system
  • Access: Fixed Steel Ladder with Safety Platform

The elevated configuration ensures adequate gravity pressure to serve surrounding buildings and community water points.


5. Implementation Timeline

The project was successfully delivered within one (1) month.

  • Rapid mobilization of materials and manpower
  • Parallel execution of civil and structural works
  • Efficient coordination with local stakeholders
  • Daily supervision and quality assurance

Despite logistical challenges associated with remote island transport, the project was completed on schedule before the Synod event.


6.  Impact and Benefits

6.1  During the 35th Lutheran Synod

  • Provided a reliable water supply to delegates
  • Supported sanitation and hygiene facilities
  • Improved event logistics and public health standards
  • Enhanced the hosting capacity of Bunsil Station

6.2  Long-Term Community Benefits

  • Continuous water supply to Bunsil Station township
  • Improved access to clean water for households
  • Reduced dependency on unreliable sources
  • Strengthened community resilience

The system remains operational and continues to serve the population beyond the event period.


7.  Sustainability Measures

  • Durable steel structural design
  • Elevated configuration to prevent contamination
  • Simple gravity-fed system minimizing operational cost, community awareness on water management and maintenance

The structure is engineered for long-term service, requiring routine inspections and minimal maintenance.


8. Conclusion

The Bunsil Water Supply Project stands as a successful demonstration of rapid infrastructure delivery under tight timelines. Completed within one month, the installation of a 20kL elevated reservoir system ensured an uninterrupted water supply during the 35th Lutheran Synod and continues to serve the Bunsil Station township community.

This project reflects ApproTech Solutions PNG’s commitment to delivering practical, high-impact water infrastructure solutions that address immediate needs while ensuring sustainable long-term benefits.
