Flovac Introduction

The Flovac system was developed for installations where other, more traditional, sewage systems cannot be employed. The system can be designed from the ground up to meet the requirements of your project and is a totally innovative solution to the problem of dealing with liquid waste where gravity fed sewage systems are not locally available.

The Flovac system provides a solution by effectively drawing liquid waste uphill over long distances. This is achieved by sucking waste from a network of satellite collection chambers by creating a centralised vacuum in a collection station.

ATAC Solutions work with Flovac to design, supply, install and operate these environmentally friendly systems.

Vacuum Creation

The vacuum main’s pressure is brought to 70kpa from 50kpa creating a 20kpa difference between the main and the external atmospheric pressure. The vacuum is created at the vacuum station at the other end of the process and takes around three minutes to reach 70kpa.

Collection Chamber

The waste from up to four homes gather in the primary collection chamber via gravity fed drains. Flovac’s underground collection chambers have a 40 litre capacity and require no power to function. They are kept at normal atmospheric pressure through the gravity fed sewage inlet pipes.

Vacuum Interface Valve

Once the level of collected liquid waste reaches 40 litres, the normally closed vacuum interface valve is activated. The Flovac’s valve is activated through increased air pressure, caused by the rising fluid level, which triggers the valve’s controller.

Vacuum Main

With the valve open, the waste is exposed to the vacuum main and the differential pressure propels the waste through the pipework towards the central collection tank at the vacuum station.

Flovac's vacuum main is stepped so the waste is gradually elevated as it travels towards the collection tank at the vacuum station.

Flovac Facts

  • No power is needed at the home or primary collection chamber
  • Vacuum pumps only run for around three hours per day
  • Liquid waste is propelled by natural atmospheric pressure
  • Liquid waste travels up hill in a stepped fashion which means that it can rest part way until propulsion returns.
  • Energy consumption can be calculated at the design phase
  • Collection tank can be 3.8 to 15^m in size and made from mild or stainless steel
