Our solution
SOLUTION
No CAPEX Required – A Fully Financed Solution
Dutch Clean Tech is redefining water treatment with cutting-edge, sustainable solutions that tackle global water scarcity. We finance, build, own, and operate wastewater treatment plants (WWTPs) on a Build-Own-Operate (BOO) basis, eliminating the need for governments and municipalities to invest in capital expenditure (CAPEX).Â
The pay-as-you-use model ensures accountability: we deliver clean water to agreed quality and volume standards (m³), charging a monthly fee. If we fall short, clients don’t pay.
SOLUTION
Proven technology for maximum efficiency
Leveraging over 60 years of expertise with our sister company, Pielkenrood A.V., we deploy advanced Sequencing Batch Reactor (SBR) technology, which:
- Uses 30% less energy than traditional plants
- Minimizes operational costs by reducing sludge production and power consumption
- Ensures high-quality treated water for safe reuse in agriculture, industry, and communities
- Unique performance guarantee: If we don’t meet agreed water quality standards, you don’t have to pay!
SOLUTION
Flexible financing – pay-as-you-use model
With backing from our own Dutch private investment fund, we are in a position to finance in full construction and operation of WWTPs in water-stressed regions. We have started to work for example in Mexico and Guatemala, where we also have established operating subsidiaries.
Our flexible pay-as-you-use model allows governments and municipalities to access clean water without financial burden.
The pay-as-you-use model ensures accountability: we deliver clean water to agreed quality and volume standards (m³), charging a monthly fee. If we fall short, clients don’t pay.
SOLUTION
Immediate & Scalable Impact
We are rapidly expanding, with a strong sales pipeline projected to grow from $10M in 2024 to $300M in 2025 and $500M in 2026.
A Sustainable Future for Water
Dutch Clean Tech is the disruptor in the water industry, enabling communities and industries to become more resilient against future water challenges. By simply treating wastewater before returning it to nature, we restore the natural water cycle, securing clean water for generations to come.

Legacy
A legacy of innovation in water treatment
With over 60 years of expertise, Pielkenrood has pioneered water treatment solutions for industries including oil & gas, automotive, and food & beverage. The company revolutionized oil-water separation with the invention of the CPI (Corrugated Plate Interceptor) in 1965 alongside Royal Dutch Shell. Thousands of its state-of-the-art water treatment plants operate worldwide, serving clients like Shell, BASF, and Chevron.
Building on this legacy, Sander Pielkenrood founded Dutch Clean Tech in 2022 to expand beyond oil & gas, addressing global wastewater challenges with cutting-edge solutions. Today, the company continues to lead with advanced water treatment plants being built in Mexio and Guatemala.
