Are they septic and greywater compatible?
✓ 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 safely
✓ Use the recommended sheet dose: 1 sheet for normal loads, 2 for large or heavily soiled loads
✓ Never pour concentrated or dissolved solution directly into soil or drains
✓ If you hand wash, rinse thoroughly and avoid dumping rinse water onto edible garden beds
✓ Keep to regular septic maintenance schedules and pump outs as recommended by your provider
