Pump Systems

The pump system provides automated control and redundancy for continuous operation and includes digital controllers, visual indicators, and fail-safes.

Electrical Supply

Supply	Loads
Three-phase power	Bore pumps (Bore 1 and Bore 2) — mode control and isolation via outdoor bore pump control panel
Single-phase power	F60 digital pump controller; ultrasonic flow meter; chlorine dosing pump

Green Shed with Wire-Mesh Doors (F60 Controller and Manifold)

Contains the F60 digital pump controller, bladder pressure tank, mechanical flow meter, and ultrasonic flow meter control box.

The previous in-shed white bore pump control panel has been retired and removed; bore pump mode control is now at the outdoor panel below.

External pipework contains:

• Ultrasonic flow meter sensors mounted to vertical pipe section
• Flush valve for maintenance and testing

KELCO F60 Digital Pump Controller

Item	Detail
Location	On the pipe manifold in the green shed with wire-mesh doors
Purpose	Regulates pump operation with pressure, flow, and timer control
Features	Multi-voltage input: 220–240 VAC, 24 VAC/DC, 12 VDC; real-time pressure display; up to 15 programmable timers; 40 Amp solid-state switch; IP64 weatherproof housing; suitable for 25 mm (1") pipe and larger; remote input for external integration; alarm light output and beacon interface
Documentation	F60 Installation Manual; F60 Programming Manual; KELCO Product Page; Online Manual (ManualsLib)

Bore Pump Control Panel

Item	Detail
Location	Outdoor panel mounted on a green post near the production bores (under the shed roof)
Replaces	Retired in-shed white control panel (removed from green shed)
Mode Select Switches	Manual, Off, Auto for Bore 1 and Bore 2
Indicators	Green Run lights for each bore (active in manual or auto); red No Flow and Overload lights (legacy — no longer used); No Flow Reset button (legacy — no longer used)
System Status Lights	Beacon-style indicators on panel top (alarm / status); flashing beacon also activated by F60 controller on alarm trigger

Manifold Area

Components located in the green shed with wire-mesh doors:

• Mechanical water meter
• Inline pressure gauge
• Pipe manifold joining both bore lines
• Isolating valves
• Bladder pressure tank (with isolating valve)

Chlorination System (Second Green Shed)

Item	Detail
Location	Adjacent to the green shed with wire-mesh doors
Contains	Chlorine dosing pump; dosing tank; chlorine chemical storage
Injection Point	Installed in the bore line outside at the eastern end of the shed
Monitoring Equipment	Secondary mechanical water meter; sensor for dosing pump activation

See 3.1.3 Chlorine Dosing for operating and refill procedures.

Over-Pressure Emergency Valve

Item	Detail
Purpose	Prevent damage from pump/system failure or closed float valves
Activation	Opens automatically if the system remains pressurized beyond the safe limit; prevents rupture or upstream damage due to over-pressurization
Location	In-line just before the chlorine dosing point

Water Quality

Monitoring

Item	Detail
Frequency	Weekly
Parameters Tested	Turbidity; chlorine residual
Reporting	NT Health Department
Standards	Aligned with Australian Standards
References	Drinking Water Guidelines; Collecting Water Samples

See 3.1 Water Supply.

Sampling Procedures

Bore Sampling

1. Disinfect tap outlet with 70% alcohol
2. Flush for at least 5 minutes until temperature and clarity stabilize
3. Collect samples:
   • Microbiological samples first
   • Avoid touching bottle rims
   • Label immediately with location, date, and sampler ID

Distribution Point Sampling

1. Tap selection: use cold taps; avoid mixers or filters
2. Flush and disinfect: remove attachments, flush 5 minutes
3. Sample order: microbiological → chemical → physical
4. Sterile collection: use lab-approved containers and techniques

Handling and Transport

• Label samples clearly
• Complete sample ID forms and chain-of-custody records
• Deliver to lab within 24 hours

Key Parameters

Parameter	Target Value / Limit	Importance
pH	6.5 – 8.5	System performance, corrosion control
Turbidity	< 4 NTU	Impacts disinfection and filter efficiency
Iron	< 0.3 mg/L	Prevents taste and staining issues
Manganese	< 0.1 mg/L	Prevents black staining in fixtures
Hardness	Monitor only	Impacts scaling in pipes and pumps
Microbiological	0 E. coli/coliforms	Compliance with drinking water safety

Maintenance

• Pump and motor inspections
• Bore flushing and cleaning
• Control panel diagnostics
• Water quality testing and reporting
• Record keeping (logs, service reports)

Version Control

Version	Date	Description
1.0	2025-09-10	Initial Release
1.1	2026-08-29	New outdoor bore pump control panel; retired in-shed panel removed; Bore image names and captions corrected

Next Review Date: 2026-03-10
