RHELGAN · OPERATIONS & MAINTENANCE
Specify the water system for the people who will operate it.
Remote and development projects need maintainable equipment, understandable controls, realistic consumables and a clear operating owner. O&M planning starts before procurement, not after commissioning.
Routine framework
Build the maintenance rhythm around the actual equipment.
Frequencies are configuration- and destination-specific. The framework identifies what the project must schedule; the exact manuals and released maintenance plan define how often and how each task is performed.
Daily / frequent operator checks
Tank level and abnormal loss · pump / controller alarms · treatment status · visible leaks · pressure or flow abnormalities · source availability.
Scheduled water-quality checks
Sampling and testing frequency set by the responsible project organisation, destination requirements and the intended water use.
Tank inspection + hygiene
Access security · roof / covers · vents and screens · sediment condition · overflow and drain · tank-interior inspection / cleaning schedule for the selected tank.
Pump + pressure equipment
Noise / vibration · seals and leakage · pressure setpoints · VFD / control status · duty / standby rotation · pressure vessel checks where included.
Treatment equipment
Pressure differential / filter condition · dosing / UV / membrane status as applicable · backwash / cleaning · consumables · calibration where required.
Solar pumping
Array cleanliness and damage · cable / isolator condition · controller status · bore pump protection · source yield and dry-run events.
Emergency / flexible storage
Fabric and seam inspection · fittings · repair history · cleaning / disinfection · dry packing and protected storage between deployments.
Records + spares
Operating log · maintenance actions · water-quality records · alarm history · spare-parts stock · consumables reorder points.
Remote-project spares
Decide what cannot wait for international freight.
The exact part numbers follow the final equipment schedule. The project should still define the spare-part philosophy before shipment.
Pumps
Mechanical seals / service parts as applicable, control components, critical sensors and selected pump spare strategy.
Treatment
Filter media / cartridges, membranes where used, UV lamps / sleeves where used, dosing parts and cleaning consumables.
Storage
Gaskets / seals, valves, level components, fasteners or repair materials appropriate to the exact storage system.
Controls
Level sensors, pressure transmitters, fuses / protection devices, controller backup / configuration records where appropriate.
Emergency systems
Repair patches, valves, hose fittings, tap components and protected packing / groundsheet items.
Operator handover
A manual alone is not an operating system.
Operator information
- System flow and normal operating sequence
- Safe start / stop and shutdown procedure
- Normal pressure, level and alarm ranges
- Source changeover or refill procedure
- Who to contact for technical support
Maintenance information
- Equipment-specific maintenance intervals
- Consumable schedule and reorder point
- Lubrication / cleaning / replacement tasks where applicable
- Inspection forms and operating log
- Long-term tank and structural inspection requirements
Water-quality control
- Sampling points and responsible organisation
- Target water-quality requirement
- Disinfection / dosing controls where included
- Response to failed test or treatment alarm
- Tank cleaning / contamination response plan
Resilience
- Low-source / low-tank response
- Pump failure or duty / standby changeover
- Power-failure procedure
- Critical spare availability
- Temporary water-supply contingency where required
Monitoring
Use alarms that lead to an action.
Level
High / low level, source loss and abnormal tank turnover can be useful where the operating team has a defined response.
Pressure + pump status
Pressure, pump run / fault and duty / standby status support faster troubleshooting on distributed systems.
Treatment alarms
Alarm points depend on the process and may include dosing, UV, differential pressure, membrane or water-quality-related controls.
Records
Remote telemetry does not replace an operating log, water-quality records, maintenance history and named accountability.
