Since the late 1970′s, as a Civil Engineer, I have been involved with the design of Septic Systems, including the training of other young engineers.
If I was limited to only one piece of advice, it would be:
Understand the Sanitary Code!
In Massachusetts, the Sanitary Code was issued in 1978 under 310CMR15.00 and commonly called “Title 5″. A major revision took place in the mid 1990′s with further revisions during the last few years. In addition to the Code changes, the State has been issuing “policies” that clarify the Code and allow for the use of various “innovative and alternative” systems and components.
I have never subscribed to the “You can’t teach an old dog new tricks” mentality. As each Code revision is published, I and my staff of civil engineers become familiar with the changes and new requirements. As new technologies are approved (for both remedial and general use) we get technical data from these companies, including in-house demonstration seminars.
I can’t understand how a designer will insist on using a conventional pipe and stone leaching system when there are so many choices available that would reduce the cost of the system. Well, maybe I do understand, they either don’t want to change, or, they are cutting their costs & fee and limiting the time spent on preparing the design plan. Some people like vanilla, but there are other flavors available and while you might pay a little more, there are added benefits in the long term.
Think of this as a round peg in a square hole. Depending on the size of the peg, you might be able to make it fit. But one size does not always fit all!
Do you remember Mission Impossible? At the beginning of the program, the team is selected from the stack of available members. While the design of a septic system is not an impossible task, having the right “team” of system components should be the ultimate goal.
In order to select the “team”, you need to understand the Code!
