DOSING LARGE WASTE TANKS: When a high water content is anticipated (e.g. for glamping sites or building sites with regular toilet flushing involving a 6 litre water cistern flush) 5 litres of Cumberland Blue per 2000 litre tank capacity is ideal. You may top up with a further 5 litres during use, if necessary.
DOSING LARGE WASTE TANKS: When higher waste concentrations are experienced, 10 litres of Cumberland Blue per 2000 litre tank capacity is more suitable You may top up with a further 5 litres during use if necessary.
DOSING SMALL TOILET WASTE TANKS: To extend the cleaning periods of small recirculating flush tanks (although not advisable) when the toilet unit may not be used for several weeks, for example: dose the toilet with 20 litres of fresh water and add 500ml of Cumberland Blue. Top up with extra Cumberland Blue as required.
