CurrentClean by Consterra: Self-Contained Cleaning for Waterway-Sensitive Sites

In many buildings, especially those located near rivers, oceans, storm drains, or other sensitive waterways, cleaning these areas is not as simple as bringing in a pressure washer. Traditional pressure washing can create overspray, uncontrolled runoff, and large volumes of wastewater that need to be carefully managed.

That is where CurrentClean by Consterra comes in.

CurrentClean is Consterra’s self-contained surface cleaning process for hard surfaces and waterway-sensitive sites. It is designed to deliver strong cleaning performance while keeping water use, overspray, and wastewater under control from start to finish.

Clean surfaces. Contained flow.

Why Traditional Pressure Washing Is Not Always the Right Fit

Pressure washing can be effective, but it is not always appropriate for sensitive, enclosed or high-use environments.

In these settings, pressure washing can create several concerns:

• Overspray onto vehicles, doors, windows, equipment, and neighbouring surfaces
• Large volumes of wastewater
• Risk of water entering drains, cracks, or uncontrolled flow paths
• Potential runoff toward stormwater systems or nearby waterways
• The need to move vehicles, protect nearby assets, or restrict access before work can begin
• Difficulty managing wastewater in enclosed, active, or high-use areas

For buildings and hard-surface areas near rivers, oceans, lakes, wetlands, or stormwater systems, these concerns become even more important. 

CurrentClean was developed for situations where cleaning performance matters, but so does environmental control.

What Makes CurrentClean Different

CurrentClean is a low-water, self-contained cleaning process designed to clean hard surfaces without relying on high-pressure washing.

Instead of blasting surfaces with large volumes of water, Consterra uses a controlled application process that combines professional cleaning chemistry, soft-brush agitation, low-pressure rinsing, and wastewater recovery.

The process is designed to:

• Minimize overspray
• Reduce water use
• Keep wastewater contained
• Avoid uncontrolled runoff
• Limit disruption in active parkades
• Support responsible wastewater handling
  

This makes CurrentClean especially well-suited for concrete walls, parkades, building exteriors, high-use facilities, and sensitive sites near waterways or stormwater systems. 

Professional Cleaning Chemistry, Used Responsibly

One of the main cleaning ingredients used in the CurrentClean process is KOH, also known as potassium hydroxide.

KOH is a professional alkaline cleaner commonly used in degreasing applications. It helps break down oils, grease, and organic buildup that can cling to surfaces over time. In simple terms, KOH helps loosen and lift grime from the surface so it can be brushed, rinsed, collected, and removed more effectively.

KOH provides the cleaning power, while the CurrentClean process provides the control. By pairing effective cleaning chemistry with a contained, site-conscious process, Consterra delivers strong surface cleaning with a higher standard of water management.

The strength of CurrentClean is not only the cleaning solution itself. It is the complete system around it.

Well-Suited for Parkades, Building Exteriors, and High-Use Hard Surfaces

CurrentClean can be used on a range of hard surfaces where controlled cleaning and responsible water management are important. This may include parkades, concrete walls, building exteriors, walkways, service areas, loading zones, and other hard-surface areas where grime, staining, and residue can build up over time.

Parkades are a clear example. As some of the hardest-working areas in any residential or commercial building, parkade walls and concrete surfaces can collect layers of grime, oil residue, vehicle emissions, mineral staining, moisture marks, and general buildup from years of use. Yet because they are enclosed, heavily used, and often connected to drainage systems, they can also be difficult to clean responsibly with traditional pressure washing.

CurrentClean offers a more targeted approach for these environments, combining effective surface cleaning with careful water use, wastewater recovery, and site-conscious handling.

Minimal Overspray, Less Disruption

One of the practical benefits of CurrentClean is that it does not rely on high-pressure washing.

Because the process uses controlled application, soft-brush agitation, low-pressure rinsing, and water vacuum recovery, it can significantly reduce overspray compared with traditional pressure washing.

For sensitive or active sites, this can mean:

• Less risk of overspray onto vehicles, doors, windows, equipment, landscaping, and nearby surfaces
• Less need to clear large areas before work begins
• Better control in tight, enclosed, or high-use spaces
• A more targeted cleaning process
• Reduced disruption for residents, tenants, staff, and building users

This is especially valuable in parkades and multi-family buildings, where coordinating vehicle movement and access restrictions can be one of the most difficult parts of a cleaning project.

Designed for Waterway-Sensitive Sites

CurrentClean was developed for sites where runoff control matters.

This includes buildings and facilities near:

• Rivers
• Oceans
• Lakes
• Wetlands
• Storm drains
• Parkades with drainage concerns
• High-use concrete or hard-surface areas

For these sites, the question is not only “Can the surface be cleaned?” The better question is:

Can the surface be cleaned without creating a larger water management problem?

CurrentClean was designed to answer that question with a careful, contained approach.

After the wall surface is treated and rinsed, rinse water is collected using a water vacuum instead of being allowed to flow freely through the site. The collected water is then filtered, tested, neutralized if required, and disposed of appropriately based on site conditions and wastewater requirements.

This is one of the key differences between CurrentClean and conventional wash-down methods: the process is designed to keep water contained and managed from start to finish. 

Better Surface Preparation

In addition to improving appearance, CurrentClean can help prepare surfaces for future maintenance work.

By removing layers of grime, grease, and surface buildup, the process can provide a cleaner base for future painting, coating, or general surface refresh work. Some stains, such as deep rust or mineral staining, may require additional treatment or may not be fully removed through alkaline cleaning alone. However, the process can significantly improve overall surface cleanliness and help restore a brighter, better-maintained appearance.

A Higher Standard for Parkade Cleaning

CurrentClean is more than a cleaning method. It is a self-contained process.

It combines:

• Professional cleaning chemistry
• Low-water application
• Soft-brush agitation
• Low-pressure rinsing
• Wastewater vacuum recovery
• pH testing
• Neutralization, if required
• Filtration
• Responsible disposal

For buildings and hard-surface areas near sensitive waterways, this approach offers a practical alternative to conventional pressure washing.

It is powerful enough to clean years of buildup, while remaining carefully managed for sites where runoff, overspray, and wastewater handling matter.

Clean Surfaces. Contained Flow.

CurrentClean by Consterra was developed for properties that need effective hard-surface cleaning without the risks of uncontrolled wash water.

For parkades, building exteriors, high-use facilities, and sites near rivers, oceans, lakes, wetlands, and stormwater systems, CurrentClean provides a more thoughtful way to clean.
