Product Description:

The Flat Tank 160 is a compact 725 litre (160-gallon) version of our standard plastic Flat Tanks for use in situations where its diminutive size and low weight may prove an advantage.

You'll find it ideal where space is at a premium and/or waste volumes are low.

Typical applications include single toilet units; showers; camping/boating waste tipping points; camping toilet / porta-potty waste disposal and catering oil waste collection.

When and Why to Use


Our plastic, above ground effluent and water tanks will be suitable for smaller campsite and glamping applications and sites, but not all, we accept that. Our flat, slide under, low environmental impact tanks will be perfect for a range of applications where:

the glamping pod is nowhere near a mains sewer
you have planning permission for short-term use only
you have units built off the ground (e.g. shepherd’s huts) and you envisage occasionally moving units
you will not be able to install underground septic tanks
you need to capture chemical toilet waste

Our robust, plastic effluent tanks solve many issues when capturing liquid waste: they are an excellent off grid solution.

Lifespan and Repairs

The oldest tanks we have supplied date back to 2010 and are still going strong.

The product is rotationally moulded as a one-piece construction from UV-stabilised medium density polyethylene (MDPE) in a ribbed design for added strength.

MDPE is particularly suitable for this application as it copes with temperature fluctuations, absorbs knocks, does not absorb smell from the (waste) contents and is easily cleaned. Repairs are rarely needed, but in the unfortunate event of damage, most repairs are readily carried out with a plastic welding tool, similar to a soldering iron.

Smells and Waste Levels


We supply a range of products ideal for plastic, effluent tanks.

Recirc HD2 Clear, for example, is an all-round sanitiser and maintenance liquid additive, which kills bacteria, removes residues and cleanses the insides of tanks to reduce / eradicate unpleasant odours.  This formaldehyde-free product has a pleasant berry perfume and is used in low concentrations (2-5 litres) as the tank is being used and/or as part of your yearly maintenance schedule, in a higher concentration (10 litres)
Our odour trap and tank breather kit combines an air admittance valve (which is generally sealed and in the "closed" position) with a small carbon filter in order to keep smells at bay. When liquid enters the tank (i.e. when a toilet is flushed and 6 litres of liquid flows into the tank) displaced air is forced upwards through the valve and through the carbon filter. When the flow of liquid has finished, the valve will close again to keep smells locked in place.
To control the waste tipped into holding tanks from portable, chemical toilets we offer an Elsan® Tipping Point
Waste levels can be controlled by visual check or by using an audible and visual level alarm such as our Apollo Alarm

Septic Tanks or Main Sewage


Holiday parks specifically purpose-designed and/or glamping sites near to a mains sewer will readily be able to connect up to the waste outlets from glamping units.

Septic tanks or sewage treatment plants can be installed as an alternative solution but you will need to consult and apply for planning permission and be ready for groundworks, soakaway to a drain field (for which a “percolation test will be required) and ongoing maintenance charges. In many cases, if you are starting a new venture and are looking for a simple way to get into business, our flat, above ground waste tanks will be an ideal starting point.

Once your business is established, you may wish to install more complex solutions, but if you're looking for the ultimate in flexibility and the ability to move tanks around as your business develops, our flat, above ground tanks have the upper hand.
