Intake to clear water tank, wet-tested and sampled before wholesome water is declared
Commissioning software for water treatment plants where coagulation, clarification, filtration and disinfection all have to prove out before a drop reaches the network.
A water treatment plant turns raw water into wholesome supply through a chain of process stages — intake screening, coagulation and flocculation, clarification, rapid gravity or membrane filtration, and chlorination or UV disinfection — each with its own dry commissioning, wet commissioning and process proving sequence. Deskely holds every tank, filter cell, doser and analyser in one register with the wet-test, regulatory sampling and wholesome-water gates built in.

The problem
A treatment train is a dozen process stages, and a spreadsheet cannot show which one is actually producing wholesome water today.
A water treatment plant is intake screens, coagulation and flocculation tanks, clarifiers, rapid gravity or membrane filters, chemical dosing skids and a chlorine contact tank, each commissioned by a different MEICA or process subcontractor on its own schedule.
When dry commissioning checklists, wet-test results and regulatory sampling data sit in separate contractor folders, the project team cannot answer the question the water company's process engineer asks at handover: which stage is proven, and which is still running on manual bypass.
Deskely tags every tank, filter cell, doser and analyser individually, so wholesome water readiness is reported stage by stage instead of taken on trust from a contractor's completion letter.
Setting up the register
Process stages, MEICA tags and analysers are structured to match the process and instrumentation diagram.
P&IDs, process flow diagrams and equipment lists are parsed into a reviewed register, so every clarifier, filter cell, dosing pump and online analyser carries its process area, its duty description and its OEM data sheet from day one.
Dry commissioning checklists, wet commissioning sequences and process proving templates are defined once per asset type and instantiated across every filter cell and dosing skid on the plant, from the first cell brought into service to the last.
Chlorine contact tank baffling, CT compliance calculations and online water quality analysers sit in the same register as the mechanical plant, so wholesome water readiness is derived from the same evidence set as clarifier and filter completion.
Execution
Dry commissioning, wet testing and process proving are gated stage by stage, not plant-wide.
Dry commissioning proves motor rotation, valve stroking and instrument loop checks before a stage is filled with water, and wet commissioning then proves flow, level control and chemical dosing under real hydraulic conditions.
Process proving runs each stage through its design duty — coagulant dose response, filter run-to-waste, backwash sequencing and disinfection CT — with results captured against the specific cell or skid before the stage is released to continuous operation.
Vendor punch from the filter media supplier, the dosing skid OEM and the instrumentation contractor is logged at the specific asset, so ramp-up is not blocked by an unrelated open item in a different process stream.
Wholesome water sign-off and handover
Wholesome water is declared from signed evidence and sampling results, not from a description of what the plant did during a trial run.
Regulatory sampling, CT compliance and turbidity performance are captured against the same register used for dry and wet commissioning, so the evidence a drinking water regulator asks for is an export rather than a scramble before go-live.
The handover pack for the water company's operations team includes as-built P&IDs, dosing calibration records and filter media specifications exported per stage, ready for the operations team from day one of supply.
Every signature carries a name, role and timestamp, which is what the client's process engineer and the regulator expect before wholesome water is declared complete rather than provisional.
The dossier
The records a treatment train leaves behind, stage by stage.
A treatment plant handover pack is not one certificate but a stack of stage records, each tied to a specific clarifier, filter cell or dosing skid. A drinking water regulator and the water company's process engineer both expect to trace wholesome water back to signed evidence, not a narrative.
Dry commissioning checklist
Motor rotation, valve stroking direction and instrument loop integrity are correct before a stage is filled with water.
Raised per asset before any process fluid is introduced to the stage.
Filter backwash and run-to-waste record
Filter media has been conditioned and the run-to-waste period discharged unacceptable filtrate before the filter enters service.
Logged at first filter start-up and after any media replacement.
Chlorine contact tank CT validation record
The baffled contact time and residual chlorine concentration achieve the CT value required for disinfection credit.
Captured during wet commissioning of the disinfection stage, before supply.
Coagulant and polymer dosing calibration sheet
Dosing pumps deliver the calculated coagulant or polymer dose across their operating range within tolerance.
Completed during wet commissioning of the dosing skid.
Disinfection and bacteriological clearance certificate
Bacteriological sampling of the clear water tank and outlet main meets the drinking water standard before supply begins.
Issued once regulatory sampling results return clear, immediately pre-handover.
Wholesome water sign-off certificate
Every process stage is proven through dry commissioning, wet commissioning and process proving with no open Category A punch.
Signed by the client's process engineer at the wholesome water gate.
How it runs
From dry commissioning to wholesome water.
Treatment plant programmes reward structure set up before the first tank is filled, because wholesome water sign-off is the point where every unproven stage becomes a delay to supply.
