Water is essential. We rely on it from the moment we wake up in the morning and make a cup of coffee until we brush our teeth at night. While most water infrastructure is hidden from sight, it is foundational to our daily lives. Our water infrastructure is aging and in need of repair to withstand the challenges of the 21st century.  We must maintain water infrastructure to deliver clean drinking water and safely carry away and treat wastewater.

EPA helps renew water infrastructure across the country by identifying needs, funding infrastructure projects through multiple programs, and providing technical assistance to connect communities and tribes to federal funding. This webpage highlights the Agency's  suite of funding and technical assistance resources that can help address water infrastructure challenges in urban, suburban, tribal, and rural communities across the nation.
