Water is easy to overlook in a poultry shed until the cleaning shift is over and the operator has to move the hoses, meters and drainage again. When we walk clients through equipment sanitising on poultry farms, we start by measuring what each task actually consumes. The question we are trying to answer is how operators can assess water use when cleaning poultry-farm equipment exteriors.
What the cleaning task really covers
"Exterior" is narrower than it sounds. For a cage bank, feeder line or manure belt, it means the frames, guards, hoppers, drive housings and panels that staff can reach during a routine wash-down. It does not include internal augers, drinkers, controllers, motors or anything that has to be isolated and dismantled. Separating the two prevents an operator from charging the entire shed wash to the equipment-cleaning task and misjudging how well one machine performs.
Build a simple task list before collecting data. For each unit record the area, visible residue, the standing time needed for dried litter to release, how far the equipment sits from a drain, and whether a wet surface may remain before birds return. The list turns a vague chore into comparable operations and makes later machine comparisons meaningful.
Use a baseline you can compare across shifts
Record the volume entering the machine instead of estimating from hose time. If the water supply to the wash bay has a meter, log its reading before and after the task. When equipment has an on-board tank, as on a hand-pushed steam cleaning machine, mark the level at the start and refill with a measured container. Repeat the same equipment, crew and soil level for several shifts, then use the average as the baseline.
Track each shift on one line: task, machine, minutes, litres, and litres per square metre or per unit. If only a flow rate and spray time are available, multiply them and treat the result as an estimate rather than a precise reading. Note manual scrubbing, a second pass, or a clogged nozzle separately. Those exceptions reveal where water is not doing the work.
Measure what a steam machine changes
A PowerDe steam cleaning machine works differently from a hose. The HMW3 hand-pushed model listed for cleaning and disinfecting hospital beds and medical machinery uses dry-steam and wet-steam modes, PTC heating and a 50 L clean-water tank, with tap water as its inlet. Its published dimensions and 4.5 kW heating power tell you the footprint and supply needed in the shed; the page does not publish steam temperature, pressure, battery capacity or runtime, so confirm those before sizing a shift around the unit.
Compare consumption by outcome. For each task log litres, minutes, chemical use, and whether the surface passed inspection after one pass. A low tank reading means little if the crew spends twice as long loosening residue or refilling mid-task. A practical comparison uses the same soil level and the same cleaning standard, then looks at total labour and consumables rather than water alone.
Steam can reduce rinse volume because less water is used to flush away loosened residue. It introduces its own checks: the correct mode for the surface, a water source compatible with the inlet, safe electrical conditions in a damp shed, and enough time for surfaces to dry. Use PowerDe cleaning equipment only where its documented modes and site conditions fit the equipment being cleaned.
Put the findings into a reusable schedule
Once the baseline is stable, set a target for the task and note any variation caused by soil, access or crew technique. Keep the same sequence each cycle: dry removal, steam application where appropriate, inspection, then a measured rinse only where required. Review the log when flock cycles, stocking density, feed changes or a new machine alter the result.
The objective is not simply to use fewer litres. It is to give operators a defensible way to judge whether a cleaning process leaves equipment ready for the next cycle while consuming water, chemicals and labour at a predictable rate.
