True or False: Composting toilets may only be used with an approved greywater system.

The statement is true because composting toilets must be installed in accordance with local regulations, which often stipulate that they can only function in conjunction with an approved greywater system. In many jurisdictions, composting toilets are viewed as part of a broader sustainable waste management system, which includes the treatment and recycling of greywater. Approved greywater systems are designed to handle wastewater from sinks, showers, and other sources, ensuring that these systems work effectively and comply with health and safety regulations.

By requiring a greywater system, the regulations help ensure that all wastewater is managed properly and reduces the risk of environmental contamination. Thus, the regulation supports the safe and responsible use of composting toilets, reinforcing the importance of having an integrated approach to waste management.
