Wheel & dust control

Wheel Wash for Construction Sites Costa Rica

Keep site mud off the public road at the one place it leaves — the exit. Automatic drive-through wheel wash systems that install in a day and recycle up to 90% of the water they use.

A construction site tracks mud onto the public road at exactly one point: the gate. Everything else — the sweeper contract, the neighbour complaints, the sediment in the stormwater drain, the notice from the regulator — is downstream of that one crossing.

A wheel wash sits on it. Trucks drive through on the way out, high-pressure jets clear the tread and undercarriage while the wheel turns, and the water drops into a tank that settles the solids out and sends the water back round. Nobody holds a hose, nothing stops, and the road stays clean.

This page is about specifying one for a construction programme in Costa Rica — how big, portable or permanent, and what the answer depends on.

Why it matters

The Cost of Mud on the Road Is Never Just the Sweeping

Sediment tracked onto a carriageway is a road-safety hazard, a stormwater problem and, in most jurisdictions, a condition on the approval that let the site open. It is also the most visible thing a neighbour has to judge the site by. Manual hosing at the gate is slow, uses more water than washing does, and stops the moment the crew is busy — which is the moment the traffic is heaviest.

One pass, no stopping, no hose. The jets run while the wheel turns, so the tread is cleaned all the way round rather than at the four points it happens to be resting on.

Size a Wheel Wash for Your Site Exit

Four questions about the site, and you have a configuration you can take to a supplier — ours or anyone else's. The model code is not a product name so much as the answer to those four questions written down.

Question 1

How long will the exit be in use?

This is the portable-versus-permanent question, and it is the only one that changes the product line rather than the configuration.

Picks the range — TW610 portable or TW620 permanent.

Question 2

How many trucks leave in the busiest hour?

Peak hour, not the daily average — the queue at the exit is what the bay has to clear.

Sets the number — tank capacity in kl, then bay length in metres.

Question 3

What do the wheels carry off the site?

How quickly the debris drops out of still water is what the tank has to give it — and how well it sticks to the tread is what the bay length has to beat.

Sets the trailing C, and can push the bay length up.

Question 4

Can you excavate a pit for the tank?

Rock, a high water table, live services or a landlord's reinstatement clause are all reasons the answer is no — and none of them stop you having a wheel wash.

Sets U or A — the tank underground or standing on the slab.

How it works

Four Stages, One Pass, Under a Minute

01

The truck drives on

Entry ramps guide it onto the galvanised wash bay. Sensors pick the vehicle up and start the cycle — the driver does nothing and does not stop.

02

Jets clear the tread and undercarriage

High-pressure nozzles are aimed at the tread, the sidewalls and underneath. The wheel keeps turning as it crosses, so the whole circumference passes through the spray.

03

Solids drop out below deck

Wash water falls into the tank under the bay. Multi-chamber settling separates mud, stone and grit. With a PCET trap fitted, a scraper conveyor lifts the sludge out continuously.

04

The water goes round again

Filtered water is recirculated for the next vehicle — up to 90% recovery, so the system draws make-up water rather than a fresh tankful. The truck exits onto a clean road.

A wheel wash sits on the one crossing that matters: the site exit. Splash guards keep the water inside the bay rather than on the crew or the road.

Where they go in

Highway & rail corridors

Long linear sites with a new access point every few kilometres, and a relocation every few months.

The two ranges

Portable or Permanent

Almost every construction site wants the portable range: it is commissioned in a day, it needs no foundations, and it leaves when the project does — onto the next job. The permanent range is for the exit that outlives the programme, where the tanks are cast in concrete alongside the base.

  • TW610 — portable · Sixteen configurations, no civil works, relocatable across phases. The default for a construction programme.
  • TW620 — permanent · Built into the slab for quarries, batching plants, depots and landfills.
  • Both ranges share the same throughput bands, bay lengths, tank capacities and PCET dirt traps — the configuration you specified above reads across.

Questions

Wheel Wash for Construction Sites — Common Questions

Why does a construction site need a wheel wash?

Because mud leaves the site on tyres, and it leaves at the gate. In most jurisdictions preventing sediment tracking onto a public road is a condition of the approval the site operates under, enforced by the local authority or the environmental regulator. Beyond compliance it is a road-safety matter, a stormwater matter, and the most visible thing the neighbours have to judge the site by.

What size wheel wash does a construction site need?

Bay length is set by how many trucks leave in the busiest hour, because bay length is how far the tread turns while it is under spray — a 4 m bay turns it once, a 12 m bay four times. Tank capacity follows the same bands, but it is also set by how long your material takes to settle, which is why light or fine debris can need a bigger tank for the same truck count. The specifier above works through it in four questions.

Portable or permanent for a construction site?

Portable, in almost every case. A construction exit moves, and a portable system is commissioned in a day with no foundations, then relocated across phases and onto the next project. A permanent installation earns its civil works where the exit outlives the programme — a quarry, a batching plant, a depot or a landfill.

How much water does a wheel wash use?

Far less than it appears to, because the water is recirculated rather than consumed. Up to 90% of the wash water is recovered in a closed loop every cycle, so the system draws make-up water to replace what leaves on the vehicle and in the sludge, rather than a fresh tankful per wash. A crew hosing wheels by hand uses more water than the machine does.

How long does it take to install?

A portable system is positioned, connected and commissioned within a single workday — no earthworks, no embedded track, and no waiting for concrete to cure. A permanent installation is on the programme of the civil works it sits in.

What does a construction site wheel wash cost?

We quote per project rather than off a list, because the number is driven by things specific to your site: bay length, tank capacity, whether the water treatment is a plain settling tank or a self-clearing PCET trap, how much excavation the tank needs, and freight to site. Those five drivers are set out in full in the specifier above.

Do we need to excavate to install one?

No. The tank can sit underground, sunk level with the slab, or stand above it — and the wash bay itself sits at slab level either way. It is only the tank that moves. Rock, a high water table, live services or a reinstatement clause are all good reasons to choose the above-ground tank, and none of them stop you having a wheel wash.

What happens to the mud the system collects?

It settles out of the water in the tank below the bay and is removed as sludge. With a plain settling tank that is a scheduled job, usually done by plant that is already on site moving spoil. With a PCET scraper-conveyor dirt trap fitted — the trailing C in the model code — a chain-and-flight mechanism lifts the solids out continuously into a chute, so nothing is shut down to clear it.

Can the system move to our next site?

That is what the portable range is for. The TW610 is a self-contained module on a galvanised base: it is lifted out, transported and recommissioned on the next exit within a workday. Sites running one to three years typically move a single system across several phases rather than buying per phase.
