A local guide to Kuopio and Joensuu: dust suppression and site washing during the summer season – how to calculate water consumption and refill routines

A local guide to Kuopio and Joensuu: dust suppression and site cleaning during the summer season This is a practical checklist for contractors who wish to plan their water consumption and refilling routines so that the brushing or washing of a site is not interrupted during the day. When the water supply is timed and the refill points are selected in advance, the fleet keeps moving and the work is consistent throughout the shift.

During the summer season, dust suppression and site washing are often carried out in “off-and-on” bursts: sometimes a dust-suppressing round is driven, sometimes a junction or traffic route is washed, and sometimes we wait for more water to arrive. That is why water logistics should be planned with the same precision as the work schedule: how much water is used, at what point in the day it is replenished, and how to ensure that functional spare equipment (hoses, couplings, valves and fastening solutions) is always available.

Lootu Oy (Kempele) manufactures sturdy and easy-to-install IBC container racks for tractors and wheel loaders. Once the rack and container have been correctly sized and securely fastened, 600–1,000 litres of water can be transported to the worksite safely and efficiently – and the filling routine can be standardised as a one-person process.

A local guide to Kuopio and Joensuu: dust suppression and site cleaning during the summer season – the rhythm of work and target levels

Before calculating litres or minutes, determine the target level: is it dust suppression (light watering intended to bind loose dust) or site cleaning (a significantly larger volume of water and often mechanical brushing as well)? In Kuopio and Joensuu, sites can range from city centre streets to junctions in industrial areas and gravel-surfaced site access routes. The same volume of water does not work everywhere, so it is advisable to link consumption to site categories.

A good rule of thumb is to always plan your daily “water budget” based on the worst-case realistic scenario: a warm, dry and windy day increases dust, whilst driving speed, nozzle settings and the condition of the brush all affect consumption. If you budget too tightly, stoppages will eat up more time than the safety margin allows for refuelling capacity.

Calculating water consumption in practice: litres, minutes and IBC container capacity

Calculating water consumption is easier if you break it down into two measures: litres per minute (l/min) and minutes per item. The combined flow rate of the nozzles gives a value in litres per minute, to which practical variations (pressure, blockages, driving speed) must be added. Once you know that a single run involves, for example, 8–20 minutes of continuous watering, you can quickly work out a rough estimate of water consumption for a single round.

An IBC container (typically 600–1000 l) is useful in contracting work because it provides predictability: the same fill volume, the same securing method, the same unloading process. If you adopt a “one tank per section” approach, work does not come to a standstill even if there is a temporary delay at the filling point – a replacement tank or another unit can carry on.

Remember that the purpose of the table is to aid decision-making: if a site repeatedly requires more than one IBC, the problem won’t be solved by “driving faster”, but by changing the process. In such cases, it is worth considering a closer filling point, using a second tank, or splitting the job into two consecutive trips.

Once the capacity is known, check the safety and load requirements: the mass of water is, in practice, the same as the volume in litres expressed in kilograms. Therefore, the design of the frame, the machine and any ancillary equipment is an essential part of planning water consumption. If you wish to verify the basic calculation using examples of 600–1,000 litres, please refer to the internal guidelines: Weight and load of the IBC container, as calculated.

Once water logistics have been standardised (consumption + refilling + route), dust suppression and washing become “routine tasks” – and downtime is drastically reduced.

Refilling routines and the use of refilling points in Kuopio and Joensuu

The aim of the filling routine is simple: You always fill it in the same way, using the same connectors and in the same order. When the routine is standardised, errors are reduced (leaks, incorrect valve positions, poorly secured hoses) and the filling time is shortened. This is particularly evident in Kuopio and Joensuu, as the distances between sites and potential refuelling points can vary considerably – and even a short additional delay can add up over the course of a day.

In practice, it’s a good idea to put together a “refill kit”: a clearly labelled hose, suitable fittings, spare seals and a clean filter. If there is debris or sand in the water, the nozzles and valves can easily become blocked, causing the flow rate to fluctuate. Basic water hygiene is not just a question of quality, but a direct factor in productivity.

If refuelling station practices vary, carry a brief set of instructions for the driver: what is required, who to ask for permission, and what the “plan B” is if the station is out of service. In Finland, site water supply and local authority practices may differ from site to site, so always check the local guidelines. General principles regarding water use and water infrastructure can be reviewed, for example, on the Finnish Water Utilities Association’s website: Water Supply Association.

Route planning and the “water loop”: how to avoid interruptions on hot days

Route planning isn’t just about navigation – it’s about managing water consumption. As the weather warms up and dust rises, that “extra” travel time is wasted, during which the target area has time to become dusty again. That’s why it’s worth planning a water loop: a route where the filling point, destinations and any storage point form a clear circle without any unnecessary turns.

The practice followed in Kuopio and Joensuu is to divide sites into two categories: (1) sites that require regular maintenance throughout the day, and (2) sites that can be dealt with “in one go”. It is advisable to place the first category close to the refuelling point or at least at the start of the route, so that you can react quickly if conditions change. The second category can be tackled as a longer route, provided that water levels and working hours allow.

A practical measure for route planning is “minutes without water”: if you have to drive 20–30 minutes empty to refill, you should be able to reach the next site straight after refilling, or alternatively you should have a second tank/vehicle on hand. In these situations, many contractors find that an IBC tank and rack offer the best compromise: the water volume is sufficient and the transport fleet remains agile.

If you would like to see a comprehensive model in which routing, loading and working speed are set out as a clear procedure (even for different locations), please also take a look at: operating model for the contractor (routing, backfilling, working speed). The principles apply directly to Kuopio and Joensuu; you simply need to swap the locations and checkpoints.

Selection and safe use of equipment: scaffolding, securing and the single-person procedure

When the aim is to minimise downtime, the equipment must support a one-person operation: the tank must travel securely on the rack, the hoses must be within easy reach, and filling must be possible without the need for a “third hand”. Lootu Oy’s IBC container racks are designed for demanding use on tractors and wheel loaders, ensuring that water logistics remain under control even in varied terrain and on-site conditions.

When it comes to safety, consistency is key: the same fastening method every time, the same pre-drive checks and the same sequence for draining. If securing the load is neglected in the rush, there is a risk not only of an accident but also that the whole day’s work will be brought to a standstill whilst the matter is sorted out. That is why I recommend that every team has a laminated “pre-departure checklist” that is always completed before setting off.

The “workload and rhythm” model for the summer season in Kuopio and Joensuu: a sample day for a contractor

Finally, we’ll combine everything into a single model that you can put into practice straight away. Think of the day as three segments: Start (work and equipment set-up), production (dust binding/washing) and verification (filling and transitions without any surprises). When there are clear procedures in place for each segment, adding new items is also a controlled process.

A typical day: In the morning, fill the IBC and carry out a quick test fill/test spray in the pits, so you can spot any blockages before you’re 15 km away. After that, do the first dust-binding lap around the “most sensitive” sections of the route. When the tank is half empty, make a decision: do you carry on to the end of the round, or do you top up straight away and tackle the next section in one go? The decision is based on your consumption log, not on a hunch.

Throughout the day, keep the “refill interval” consistent – for example, always after every two sites or at a specific time of day, if the conditions are consistent. In the afternoon, carry out a maintenance round of those sites that generate the most feedback (dust, mud, ruts). When the work is finished, rinse out the hoses and check the seals – it’s a small effort that will make getting started the next day a quick process.
