Salt Lake City sits in a valley with dense clay soil that shifts with moisture changes. During spring snowmelt and summer irrigation, the soil expands. During winter freezes and dry periods, it contracts. This constant movement stresses underground sewer lines, especially older clay pipes that were never designed for this cycle. Cracks form at pipe joints and along the pipe body. Tree roots from the city's mature urban forest sense moisture inside these cracks and grow toward it. Once roots penetrate, they expand inside the pipe, catching toilet paper, grease, and solid waste until a complete blockage forms.
