What must the design of the soil dispersal component comply with?

The design of the soil dispersal component is required to comply with the methods outlined in WAC 246-272A-0200 because these regulations specifically govern the standards and practices that must be followed for the design, construction, and maintenance of onsite sewage systems in Washington State. WAC, which stands for Washington Administrative Code, provides detailed technical requirements that ensure the systems are safe, effective, and environmentally sound.

By adhering to these specific methods, septic installers can ensure their designs will function properly and will be accepted by local health authorities. This compliance with WAC 246-272A-0200 is crucial for protecting public health and the environment, as it sets forth parameters concerning soil types, system sizing, and installation techniques that are scientifically backed and regulatory mandated. Consequently, while other regulations or guidelines might influence certain aspects of septic system installation, WAC 246-272A-0200 is the foundational reference for the soil dispersal component's design.
