Water Usage With a Septic System

Food waste disposers use water to transport ground-up organic matter through internal plumbing and sewer pipes, and so food waste disposers are often perceived as water wasters.

Myths are perpetuated that they will hydraulically overload wastewater infrastructure, both centralized and decentralized, septic systems. To address these concerns, research was undertaken on quantifying the amount of water used by food waste disposers.

A review of ten studies found that the water use of food waste disposers is less than five (5) litres per household each day, which is around one flush of the toilet of water per day.

Organic Loading on a Septic System

The use of food waste disposers does add organic material to wastewater and a septic system. Research from ten states in the US specified that where food waste disposers are commonly used, the Total Suspended Solids increased by 20 grams per day.

Another finding from the research found high carbon to nutrient ratios indicates there may be a positive impact for enhanced biologic phosphorus removal at wastewater treatment plants, which implies there may also be potential benefits of this high carbon ratio on nutrients discharged from septic tanks.

This means the food waste’s high carbon content could help remove nutrients like nitrogen and phosphorus when they discharge into drainage fields.

Environmental Benefits

Each year in New Zealand, tons of food waste is trucked to landfills. Once there, it quickly decomposes and produces methane, an environmentally harmful greenhouse gas that is at least 21 times more potent than CO2.

While composting provides one approach to tackling the food waste management challenge, it isn’t always practical for today’s busy lifestyle.

Enter InSinkErator®. Our food waste disposers provide a convenient and environmentally friendly alternative to transporting leftovers to landfills. Plus, capable wastewater treatment plants can even recycle food scraps into energy and fertilizer.
