What is a septic tank?

Septic tanks can provide what is known as primary treatment to the wastewater at properties which are not connected to the mains sewer system. Primary treatment has a tank that collects and treats wastewater. A septic tank works by retaining solids and allowing them to settle so they can be partially broken down by biological action leaving only the remaining effluent to flow down the outlet drain. This effluent is then sufficiently treated to soak into the ground in an underground soakaway system.

Understand the regulations

All septic tank systems installed in Hampshire must meet general binding rules. Before you can install a septic tank, it’s vital to get a handle on the various permissions you’ll need to obtain and regulations you’ll have to adhere to before, during and after the installation process. 

You may need planning permission and/or building regulations approval, you’ll need to make sure you’re aware of how much sewage your property is likely to discharge, where the treated wastewater will be released into the ground and find out whether your property is in a protected zone. Depending on your expected discharge rate, you may be required to pay a fee to apply for a specific permit.

A typical septic tank is made up of two chambers and makes use of natural processes to treat sewage (hence the name septic). Wastewater enters the first chamber and separates the sewage into solids which settle at the bottom of the septic tank, oils and greases which form a layer of scum at the top, and a middle layer made up relatively clear water. 

The wastewater enters the second chamber where any remaining solids are deposited and exits via an outlet pipe into a drain field or soakaway. The remaining scum and solids in the tank are broken down by bacteria and into sludge which should be professionally removed at regular intervals.
