Flovac Systems products

Vacuum system installers prefer the Flovac PE pit because of its ease of installation, low cost and that it comes pre-assembled to site. Operators prefer the Flovac PE pit as it restricts any contact with sewage, there are no odours and infiltration is eliminated. Confined spaces are not an issue and dropping things in the pit (like mobile phones) no longer means that they disappear down the sewer line.

The Vacuum Pump Station (VPS) houses a collection tank (to collect the sewage); discharge pumps to send the sewage to the treatment plant; controls to automate the station and vacuum pumps which create a negative pressure in the vacuum mains. (-0.5 -0.7 bar). Usually only one VPS is required in an average sized catchment. All electrical and mechanical equipment is housed in a dry environment and the operator is not in contact with any wastewater. All odours are minimized through the use of a bio filter.

The Flovac Vacuum Valve has a 50 year design life with no electrical components and requires only minor parts upgrades every ten years. The collection pit houses the 90 mm (3 inch) Flovac vacuum valve which interfaces between the atmosphere coming from the gravity lines and the negative pressure in the vacuum mains created by the vacuum pumps at the VPS. The VPS may be as far as 5 km (3 miles) away from the last collection pit.

Early vacuum sewerage systems are about to get a makeover thanks to the Flovac R&D team in conjunction with the Production team in The Netherlands. Clients from many parts of the world had struggled with getting reliable and easy to use vacuum valves to fit the earliest vacuum systems installed in the 1960’s and 1970’s.

The Vacuum Mains (either PE or PVC) are designed to be as shallow in the ground as possible and are laid at a 1/500 grade. The contractor builds steps in the pipework to keep the mains from getting too deep. The more steps that are installed, the more hydraulic losses are created, lessening the distance that the mains can go. It is important to have collection pits evenly distributed around the catchments and along the vacuum mains to ensure fast movement of sewage to the VPS.
