Water and Wastewater

RETTEW provides solutions regarding water resource planning, management and related regulatory matters. Our extensive combination of technical, scientific and permitting expertise enables us to integrate water resource considerations across services. Active participation in regulatory and legislative work groups keeps us abreast of a constantly changing regulatory and technological environment, and we use our in-depth knowledge and expertise to anticipate challenges that might affect your project and the people you serve.

The comprehensive integration of hydrologic, ecologic, planning and engineering-related water resource expertise with regulatory water policies allows us to meet our clients’ needs, while providing resource sustainability. We work with a variety of public- and private-sector clients to address everything from municipal collection, distribution, conveyance and treatment systems to water resource permitting and water supply studies for oil and gas sites. In addition to design, we support homeland security efforts by specializing in vulnerability assessments of these systems to identify and address any potential security risks.
