Are Sensitive Laundry Sheets safe for septic tanks and greywater systems?Updated 10 hours ago

TL;DR: Sensitive Laundry Sheets can be used with septic tanks and greywater systems when used as directed. Use the recommended number of sheets per load, avoid overuse, and check local regulations or your septic service provider for site-specific advice.


Septic tanks

When used at the recommended dosage, Sensitive Laundry Sheets are compatible with most domestic septic systems. Avoid repeatedly over-concentrating detergent in a single load. Regular maintenance of your septic tank and following the dosing guidelines will reduce the chance of upsetting the biological balance.

Greywater systems and irrigation

If your laundry wastewater goes to a greywater system used for garden irrigation, follow local guidance about acceptable detergents and crop types. For subsurface or non-edible garden use, normal machine loads are usually fine when you stick to the recommended sheet per load. For surface irrigation or use on edible plants, check local regulations and best-practice guidance first.

How to use Sensitive Laundry Sheets safely

  • Use the recommended sheet dose: 1 sheet for normal loads, 2 sheets for large or heavily soiled loads.
  • Do not pour concentrated or dissolved Sensitive Laundry Sheets solution directly into soil or drains.
  • Rinse thoroughly if you hand wash and avoid dumping rinse water onto edible garden beds.
  • Keep to regular septic maintenance schedules and pump outs as recommended by your provider.
