3800 Litres Septic Tank - 12 Population

3800 Litre Septic Tank for 12 Person

When connection to a mains sewer isn't practical, septic tanks are worth considering. They not only solve the practical problems of storing sewage for tens of thousands of homes, they disperse the treated water in a way safe to the environment.

What size Septic Tank do I need?

This depends on how many people are using property and not how many live there. Naturally, the bigger the property, the more toilets, sinks and showers there will be. As a starting point, British Water state in their Flows and Loads guide that a 3 bedroom property would need a 5 population septic tank. This would therefore be a 2800 litre unit. For every bedroom added, the population capacity of the septic tank would then increase by 1.

If there is more than 1 dwelling on the site then the properties should be sized indiviually and then combined.

Available in a variety of sizes to suit your application, there is something available for most size properties.

How do septic tanks work?

Similar in use to a cesspit tank apart from the collected effluents are treated using a simple process which allows the wastewater to flow to the surrounding ground areas through a network of drainage pipes. Cesspit tanks are sealed units that collects and stores sewage and wastewater. It is not connected to any sort of drainage system and must be emptied regularly by a professional. 

Our 2800 litre Septic Tanks are designed to meet both the installation requirements and the standards of discharge specified by BS 6297:1983.

Each unit achieves a high degree of settlement, producing a quality effluent for discharge to a land drainage system.

Is there sufficient room for the drainage?
