Septic tank covers shall have a minimum cross-sectional opening of how many inches?

  1. 10 inches

  2. 15 inches

  3. 20 inches

  4. 25 inches

The correct answer is: 15 inches

The appropriate minimum cross-sectional opening for septic tank covers is 15 inches. This specification is important for several reasons related to safety, accessibility, and maintenance. A 15-inch opening allows for adequate access to the septic tank for inspection, maintenance, and pumping operations. It is also necessary for the safe entry of tools and equipment that might be used by septic system professionals. Having a cover with a minimum opening size helps in ensuring that the tank can be inspected for its condition and performance without unnecessary complications. It balances the need for access with safety concerns, as larger openings could potentially pose a risk if not properly secured. This standard, therefore, reflects best practices in the industry to promote both efficient serviceability and safety for those working with septic systems.
