About 1 million households in the UK use a septic system as the means of processing waste-water and sewage disposal. Septic tanks are something we often don’t like to think about, and normally we don’t, until there is a problem.
There is much discussion amongst septic tank owners about the types of laundry and dishwashing products to use. So no wonder that we are frequently asked for advice on this topic.
Powders v Liquids
Quite simply, powdered laundry detergents are more likely to form clogs and sludge sediment in a septic system, reducing the rate of bacterial digestion and potentially blocking drains too. Inexpensive powdered detergents may contain excessive amounts of filler or carrier. The best solution is to use a liquid laundry detergent or pods that contain no fillers which could harm a septic system.
Bio v Non-Bio Laundry Products
The choice is yours. There’s really not a lot of difference. Bio products have the edge – just – simply because they contain enzymes, similar to those produced by Muck Munchers.
These enzymes break down complex organic molecules, but unlike microbes they do not digest them, but simply move them on, further down the drain. Of course, the other benefit of Bio products is they help in removing fluff on clothes in the wash. The downside – some people are allergic to them.
Avoid Phosphate Detergents – Read the Label
The most important thing to note is that the detergents containing phosphates are not exactly environmentally friendly. The good news is that phosphates are no longer present in most major detergent brands.
The environmental issue with using phosphate-based detergents is that too much phosphorus relased into water causes ‘algae bloom’, where plant life in lakes, ponds, or streams overgrows and limits the amount of oxygen animal and plant life receives. Essentially, plant organisms in the water are over-fed and grow faster than the water can naturally regulate itself.
Antibacterial Detergents and Sanitisers
By definition they destroy bacteria. That’s not good for septic tanks and there is a growing body of evidence that good bacteria on our skin is a contributor to overall personal health.
Mouthwashes, while antibacterial, in our opinion may be a necessary essential to good oral hygiene. Don’t be concerned, Muck Munchers has been developed assuming that with modern living, sometimes you just have to rinse or flush some antibacterial products.
Oxy Laundry Products and Bleaches
If a product is described as ‘Oxy’ it’s almost certain to be based on oxygen producing ingredients, such as Sodium Percarbonate, which means that they are microbe friendly and can even benefit septic tanks. The same goes for Hydrogen Peroxide based bleach products that are effective laundry additives and excellent general sanitisers.
