Sewerage Vacuum System 2

[waseem19]

anyone has a good source of information on this topic

this a system for waste water collection by sucking the waste water to your plant rather that gravitate it or pump it. it is mainly for flat or difficult terrain with low flow areas.

An actual project design report , sketches ,drawings would be most valuable and appreciated.

Try the US Environmental Protection Agency. They have a manual on Alternative Wastewater Collection Systems first published in 1991. Start at

http://www.usepa.gov

and search from there. It will lead you to other sources.

Good luck

Do a search for AIRVAC. They are one of the leading manufacturers of vacuum collection systems and have a very good system. They can also assist with the hydraulic design of the system.

I would also recommend that they be involved in assistance of the vacuum pipe installation. It can save a lot of headaches and potential problems.

I have a great deal of experience, both in the design and operations and maintenance of a vacuum sewer system. I can give you plenty of information, insight and advice. Do not solicit advice from Airvac, they are sellers, unless you want to know about thier products.

There are many considerations that designers do not take into account when developing these systems, which in the end will not bode well for the Owner or you as a design company.

You can contact me direct at (780)573-1884 and we can set up a conference call or arrange a meeting.

I'm searching information on the Sewerage Vacuum System for a main sanitary sewage but I can't find any information even at

http://www.usepa.gov

Do anyone knows where can I get any inforamtion on this?

Dear Waseem19,

I would highly reccomend AIRVAC. Here in Australia, they install the majority of Vacuum Sewage systems. True they are sellers, but they really know their stuff. Plus it would seem that they have the best vacuum sewage valve on the market (very reliable, with good solids handling).

Good Luck,

Berko

mtroche,

I presume you are in the initial stages of the design of your effluent collection system. Considering the other available options for these systems, have you firstly exhausted the other available options?

Maintenance and operation of a vacuum sewer system is firstly expensive and secondly time consuming as opposed to a gravity system or positive pressure system. Of particular concern is the valve itself and some problems they have with domestic sewage. The design, while improved, have not really changed much over the years and when the fail, they usually fail open causing a loss of vacuum on the the system, which forces the station pumps to continuously operate.

I have extensive experience with the Airvac system, and find they have a good product....it's the philosophy of a vacuum system over other systems that carries much debate.

For clarity from the start, I am a seller as well. Sellers are very useful in these forums as they are like the specialist engineers insomuch as they have spent the time and money to develop specific solutions to specific problems as they arise. Most concerns have been an issue somewhere, some time previously - most times it is the manufacturers that supply a product to overcome the problem. Furthermore it is these companies that have the resources to focus on the single isues. My 2 cents..
Vacuum as opposed to pumping and using the traditional risers is a reasonable plan B however air leakage through frames, covers and low integrity piping will determine viability in the long run.

I am a new member to the Eng-Tips forum, and was very interested to read Waseem's comments. I work for a company who design and install Vacuum Flushing systems in the UK. The systems can be utilised in Rectangular/Circular tanks and also in pieline systems.

The system is very energy efficient in operation and cost effective in maintainable parts. I would be more than happy to assist with any information you may need.

Hope this helps

I would recommend to look at :

http://www.quavac.com

They take care of the design of a vacuum sewerage system which is the most important to have a proper working system.

The Vac system we have in a small village outside York is not very reliable. We are regularly buying spare parts for the system. The Vac pump manufacturer was un reliable and had lost impellar specifications.

We have accumulator and 2 foul and 2 vac pumps.

We also have a biosphore rotating drum attached.

If I were you I would monitor the vac alarm but make the wells placed at each valve large enough so that if the system alarms for low vac then it can be dealt with at a lower priority and not out of hours.

Another advantage of the system is that you can control the amount of surface water you take into the system saving energy in treatment and transport.

Hope that helps.
Rob

- ps... If anyone has any energy saving ideas for this type of system please let me know.

One problem with a vacuum sytem is that it is not dedicated to a housing lot. to make the system economic the vacuum system will share four or more houses to a pot. If there is a blockage caused by one neighbour who pays the plumber?

Low pressure sewage systems seem to be the flavour of the month for low lying flat areas.

i have had many dealings with vaccuum sewage systems and when new are generally good however as settleent in the suround ground occurs potential problems can start when joins spring. A recent system that was installed at a local health and fitness centre wasremoved after 2 years due to regular failures and problems. Be careful is all i can say, the principle is OK but the long term whole life costs can be hi

sawtry,
Was the specific problem you mentioned some inherent problem of the vacuum sewer concept, or instead some problem with the specific installation/piping/joints chosen for its implementation in that case? If the problem was with joints of pipe, what kind of pipe/joints were used?
