What You Need to Know About Vacuum Sewers

Benefits

There are several alternatives for consideration to provide sanitary sewerage for municipal services. While gravity sanitary sewers may be the preferred solution, flat terrain, shallow groundwater or rock can increase construction cost prohibitively. Typically gravity sewers can extend (at 0.4% slope) for only 2,000 feet in flat terrain (8' drop) before a lift station is required. If houses have basements or groundwater/rock are issues, these problems can be exacerbated. Vacuum sewers can extend as far as 5,000 feet in all directions at 0.2% slope and have many cost-effective uses and a good ‘tool' for use by municipalities and engineers. Flatter slopes to the vacuum lines and shallower construction provide definite advantages over traditional construction. This live audio conference will identify basics of vacuum sewers, locations for use, design issues, and use case histories as examples of the use of vacuum sewers.
