The Oregon State Legislature introduced House Bill 3190 on April 2, 2025, aiming to enhance water conservation standards for plumbing fixtures in new and renovated buildings. The bill seeks to address growing concerns over water usage amid increasing drought conditions and the need for sustainable building practices.

Key provisions of HB 3190 include stricter regulations on the average water consumption of new toilets, urinals, shower heads, and faucets. Specifically, the bill mandates that toilets must not exceed 1.6 gallons per flush, urinals 1.0 gallons, and both shower heads and interior faucets 2.5 gallons per minute. These standards align with performance requirements set by the American National Standards Institute and other recognized standards.

The bill also outlines exemptions for certain situations, such as when existing plumbing systems cannot accommodate the new fixtures or when maintaining the historic character of a building is necessary. Additionally, it prohibits the sale of non-compliant new fixtures and sets standards for the sale of used fixtures.

Debate surrounding HB 3190 has highlighted concerns from various stakeholders. Supporters argue that the bill is a crucial step toward sustainable water management and reducing environmental impact. However, some opponents express worries about the potential financial burden on property owners and the feasibility of retrofitting older buildings to meet the new standards.

The implications of HB 3190 extend beyond environmental concerns; it could also influence the construction industry and property values, particularly in areas with older infrastructure. Experts suggest that while the bill may initially pose challenges, it could ultimately lead to long-term savings in water costs and contribute to Oregon's broader sustainability goals.

As the legislative process continues, the bill's future remains uncertain, with potential amendments and further discussions expected in the coming weeks. If passed, the new regulations will apply to property tax assessments starting July 1, 2026, marking a significant shift in Oregon's approach to water conservation in building practices.
