Begin developing your strategy for wastewater use reduction based on the option you’ve selected. Research low-flush fixtures, water reuse, and onsite treatment.
Check with the local municipal wastewater department to see if reclaimed water is available as a source of non-potable water for toilet flushing. If it is available, this will contribute to compliance with Option 1.
Determine if composting toilets or waterless urinals are appropriate for your project. While not common, waterless fixtures can go a long way toward achieving this credit. Composting toilets do affect programming and layout, however, so be sure to consider them early in the planning stages. However, projects often find that installing only a few composting toilets can help them to achieve this credit while offering a great educational asset.
Consider reducing potable wastewater use by 100%, or treating 100% of your wastewater onsite to tertiary standards, for an Exemplary Performance point.
Perform a water-balance study for the entire project in order to make an informed decision about where to focus your water-saving efforts. Survey your project and site for all water sources—stormwater, graywater, and onsite wastewater.
The staff person responsible for overseeing the comprehensive plan communicates regularly with all service providers and conducts routine site inspections and evaluations to ensure that the plan is in place and functioning as intended.
