This Do’s and Don’ts guide to running a small package wastewater (sewage)
treatment plant can be downloaded from our website.
Please think before you put anything down the sink, toilet or drains!
Do – cleaning products:
• Do refer to the manufacturers’ recommended doses of household
cleaning products according to the hardness of your local water; do try
to use cleaning products little and often so the sewage treatment plant
isn’t overloaded; do try to stick to the same washing, dishwasher and
other cleaning products – the bacteria will work more efficiently with
familiar products
Do – washing machines:
• Do use liquids, not powders in washing machines and dishwashers;
do try to spread your clothes washing throughout the week
HINTS & TIPS
It is important that your family, guests and visitors are made aware that your house
is connected to a specialist, biological sewage treatment system. They need to
know that they should not put anything down the toilet, sinks or drains which could
harm the bacteria or block the system.
