Duty, standby and assist pumps proven wet before a station is left unattended
Commissioning software for pump stations where wet well level control, duty/standby changeover and standby power all have to prove out before a station is trusted to run alone.
A water or wastewater pump station lives or dies on its wet test: duty and standby pumps switching correctly on level, VSDs holding pressure or flow set points, telemetry reporting status back to the control room, and standby generation picking up seamlessly on mains failure. Deskely holds every pump, valve, level sensor and generator in one register with the wet-commissioning and unattended-operation gates built in.

The problem
A pump station is small, but it fails alone at 3am, and a spreadsheet cannot show whether the standby pump has actually been proven to take over.
A pump station combines civil wet well construction, mechanical pump and valve installation, electrical VSD and switchgear commissioning, and a telemetry outstation reporting back to a control room, often built by three separate contractors on overlapping schedules.
When duty/standby changeover tests, high level alarm proving and generator changeover records sit in different contractor sign-off sheets, nobody can confirm before the station is left unattended that a genuine failure will actually trigger the standby response.
Deskely tags every pump, valve, level sensor and the generator individually, so unattended-operation readiness is reported from proven changeover tests rather than assumed from an installation completion certificate.
Setting up the register
Pumps, valves, instruments and standby power are tagged assets matched to the P&ID and control philosophy.
P&IDs, control philosophy documents and electrical schematics are parsed into a reviewed register, so every pump, non-return valve, level sensor and the standby generator carries its duty description and its control logic reference from day one.
Dry commissioning checklists, wet commissioning sequences and duty/standby changeover test templates are defined once per station type and instantiated across every pump station in a programme, so a hundred-station rollout does not mean redefining the test set a hundred times.
Telemetry point lists and alarm configuration are held as their own record set, distinct from mechanical commissioning, because they gate the control room's separate SCADA integration acceptance.
Execution
Wet commissioning, duty/standby proving and telemetry testing are proven station by station before handover to unattended operation.
Wet commissioning fills the wet well and proves pump start and stop levels, VSD pressure or flow control, and non-return valve operation under real hydraulic conditions rather than a dry simulation.
Duty/standby changeover is functionally tested by forcing a duty pump fault and confirming the standby unit starts within the specified time, while high level alarms and standby generator changeover are proven with the same rigour.
Vendor punch from the pump OEM, the electrical contractor and the telemetry integrator is logged at the specific pump or panel, so a rollout across dozens of stations is not blocked by one unrelated open item.
Unattended operation sign-off and handover
The station is left unattended from a proven failure response, not a description of what the pumps did during a supervised test.
Unattended-operation sign-off draws on the same duty/standby, high level alarm and generator changeover records built during wet commissioning, so the evidence the operations team requires before leaving the station unmanned is an export rather than a rebuild.
The handover pack for the operations and maintenance team includes as-built control philosophy, pump curves and telemetry point lists keyed to the station register, ready for the first call-out from day one.
Every signature carries a name, role and timestamp, which is what the water company's operations manager expects before a station is added to the unattended asset base rather than kept on manual supervision.
The dossier
What proves a station safe to leave unattended.
A pump station is only accepted once it can run without an operator present, which means duty/standby changeover, standby power and alarm dial-out all have to be demonstrated as a set, not assumed from a single successful pump run.
Wet well level control proving record
Level probes and float switches start, stop and stage pumps at the correct levels across the full operating range.
Captured during wet commissioning before duty/standby testing begins.
Duty/standby/assist changeover test record
Pumps rotate duty automatically on a set cycle and the standby pump starts correctly on a simulated duty pump failure.
Run once wet well level control is proven and pumps are running under load.
Standby power transfer and run test log
The standby generator or UPS starts, transfers load and sustains the station through a simulated mains failure.
Tested during commissioning of the electrical and standby power system.
High-level alarm and telemetry dial-out test
A simulated high-level or fault condition raises an alarm at the control room within the required response time.
Verified after SCADA and telemetry connection to the station is live.
Non-return and isolation valve function test
Rising main non-return valves and isolation valves seat and operate correctly to prevent backflow on pump stop.
Completed during wet commissioning alongside pump proving.
Unattended operation sign-off certificate
Every control, changeover and alarm function has been proven together, clearing the station for unstaffed operation.
Signed once all station-level tests are complete with no open Category A punch.
How it runs
From wet well fill to unattended operation.
Pump station programmes reward a register that scales across dozens or hundreds of stations, because the changeover test that matters is identical everywhere and should never be redefined station by station.
