In the context of selecting wastewater piping materials, the factor of color is not typically considered. The primary considerations focus on functionality and performance characteristics that affect the piping's ability to handle the specific conditions found in wastewater systems.

Chemical resistance is critical because wastewater can contain a variety of corrosive substances that can degrade certain materials. Understanding the chemical composition of the wastewater helps ensure that the chosen piping material can withstand these conditions without failing.

Temperature is another significant factor, as wastewater can vary in temperature due to various influences, including environmental factors and industrial processes. Piping materials must be suitable to maintain structural integrity and functionality at these temperatures.

Pressure ratings are also vital because wastewater systems often operate under varying pressures that can affect the piping's performance. Ensuring that the piping can handle these pressures without risk of failure is crucial for the long-term viability of the plumbing system.

Color, while important for aesthetic considerations in some contexts, does not influence the mechanical, chemical, or thermal performance of the piping and is therefore not a factor in the selection process for wastewater applications.
