The story

Archway Partners, a sustainability-focused real estate developer in Florida, set out to create The Flats on 4th, an affordable, age-restricted housing community. Their goal was to provide high-quality residences for older adults while integrating advanced sustainability technologies that meet both environmental standards and local regulatory incentives.

Local zoning initially limited the number of apartments, and Archway Partners aimed to maximize housing units while meeting strict sustainability and regulatory requirements. High water usage in showers and sinks posed both operational and environmental challenges, and the project needed a solution that would be practical, cost-effective, and eligible for incentives.

Hydraloop’s water recycling system helped us secure a density bonus, adding 16 more affordable units at Flats on 4th. This is the first of three projects where we’re proud to invest in sustainable, water-saving solutions.
