Dutch Startup FieldFactors Secures €1.6M To Expand Rainwater Reuse In Cities

The funding was led by Dutch impact investor Connect the Drops, with support from Tailwind Climate, Amplifica Capital, Vanzal Limited, and the Water Innovation Fund.

Along with capital, the investors bring industry knowledge and networks to help FieldFactors grow its impact in urban water management.

Karina Peña, CEO & co-founder of FieldFactors, says, “We help cities capture every drop and reuse it smartly. Our goal is simple: make rain part of the solution, not the problem.”

“This funding marks a key milestone for FieldFactors as we shift from pilot projects to large-scale implementation. We are proud to work with cities, developers and corporate partners to make urban water systems more circular, resilient and future-proof.”

Their solution, called BlueBloqs, collects rain where it falls, purifies it using biofiltration, and stores it underground. The stored water can later be used for irrigation, cooling buildings, or recharging aquifers.

FieldFactors works with cities, industries, and developers in the Netherlands, Spain, and Mexico to solve water challenges. Their systems help reduce flooding, fight drought, and support urban cooling and greening.

Their BlueBloqs technology is already in use in cities like Rotterdam, The Hague, and Madrid, where it has helped cut stormwater runoff and lower potable water use, while improving urban spaces.

CEO & co-founder, Peña, says, “We help cities stop wasting rainwater. By reusing it locally, we reduce stress on infrastructure and support greener, healthier neighbourhoods.”

FieldFactors will use the new funding to speed up growth and expand globally. The company plans to scale up production of its BlueBloqs rainwater reuse system to reach more markets.

The funds will help set up operations in Europe and support the launch of first projects in Mexico, marking its entry into Latin America.

Mexico, already struggling with serious water issues, faces both frequent urban flooding and growing water scarcity. Each year, intense rains cause over $230 million in damages, while climate change could bring severe water shortages by 2040.

“Mexico shows exactly why circular water systems are urgently needed. It’s the ideal place to start bringing our solution to Latin America,” says Peña, CEO & co-founder of FieldFactors. These combined pressures highlight the need for investment in alternative water supply solutions that can manage excess rainfall while addressing growing demand.

FieldFactors also plans to grow its technical and commercial teams to meet rising demand and scale its impact effectively.

Jan Otto Ooms, Partner at Connect The Drops, mentions, “The elegance of the BlueBloqs system is that the concept is simple to explain, and it will convince a lot of people of the benefits. FieldFactors had the product and the team to deliver its impact at scale, helping communities to rethink their rainwater management.”

Anna Raptis, Founding Partner at Amplifica Capital, adds, “FieldFactors is redefining how cities and industries manage water. Their technology not only cuts stormwater discharge costs by up to 20 per cent and reduces potable water use by as much as 80 per cent, but also delivers real environmental and financial value.”

“What sets them apart is their ability to serve both industrial clients and local communities—like in their recent aquifer recharge project with Microsoft in Madrid. With strong traction in Mexico and a team deeply committed to livable, green cities, we’re excited to help them grow their impact across Latin America.”
