Vacuum sewerage projects can be found in over 40 countries as a low cost, environmentally friendly and reliable method of transferring wastewater away from houses to treatment plants.
The key driver of the Flovac company and the products that are offered, is in reducing mans footprint on the environment with respect to the impact that wastewater systems have on energy, water consumption and the environment.
Nearly all vacuum sewerage projects are area’s with very bad ground conditions. (high water table, hard rock, acid sulphate soils etc.) The objective of the designer is to keep all infrastructure as shallow in the ground as is possible.
The average size catchment area for a municipal sewerage system is 1,000 houses, but this can range from a single house to complex systems with over 500,000 people.
Septic Tank Replacement Projects
Most of these areas have not installed conventional gravity systems due to the high costs involved. The town may be on very flat land or a high water table that would require very deep gravity mains causing not only a high maintenance cost but also a high construction cost. Deep gravity lines may be impossible in certain areas because of the wide trenching interfering with homes, trees or other services. Vacuum sewers provide an ideal solution.
New Residential Developments and Resorts
Vacuum Sewerage technology has been fantastic for developers. Many areas that were once thought too difficult or expensive to sewer have now opened up.
Vacuum systems almost always cost less to install and less to maintain than traditional gravity systems, and certainly less than pressurized systems with grinder pumps. A single vacuum pump station will usually be sufficient to support an entire project.
Deployable Vacuum Sewerage Systems
Temporary Camps, whether emergency, workers accommodation, mining, military or refugee need to transport sewage from ablution blocks, kitchens and laundries. Installation of pipework can be time consuming, expensive and be damaging to the environment.
Flovac’s deployable vacuum system can be deployed to site and established within 24 hours. Upon redeployment can be packed and ready for transport within 24 hours, leaving the site as you found it.
Train Sewerage Extraction Systems
As trains come into the yard maintenance crews can hook up a vacuum hose via a fitting to the trains sewage holding tanks. The tank is evacuated via a push button control on the Flovac Valve. Sewage goes via a vacuum main back to a series of vacuum pumps and then discharged to the gravity network.
Flovac has now installed extraction systems for a number of clients in particular for the Deutsche Bahn’s ICE network, including systems in Frankfurt, Cologne and Dusseldorf.
Projects have also been done for Irish Rail, SBB Swiss, RENFE Spain, OBB Austria and France SNCF.
Sewerage Systems for Marina’s and Port Facilities
Vacuum systems can handle either small or luxury boats, larger commercial vessels or
ferries. An easy coupling attached to a flexible hose can be attached to the vessels sewage holding tank. The manual or automatic on/off switch can also be timer controlled, coin or card operated or remotely electrically controlled. Larger boats can pump out into a collection pit connected to sufficient Flovac valves to handle the volume
