    Reader Comments & Q&A

    Question: how do I get educated to perform septic inspections in New York State?

    My business partner and I are looking to get into Blackwater assessments and phase 2 inspections.

    We have multiple licenses that I believe will be a need for the phase two inspection such as mold assessor, asbestos inspector, lead (soon) and the basic well testing / soil testing capabilities .

    Do you know what else the phase 2 assessments consist of ? I am under the impression it’s a bunch of general knowledge regarding building which we have from home inspections then testing credentials of certain materials , soil or substances based on the current and past occupancy uses through out the years .

    Also do you know what black water assessments consist of? - Anonymous by private email 20223/01/22

    Moderator reply:

    What I did was to drive over to MA and take their septic inspector certification course. In my opinion that state has the best education program in the country for this topic. When you've done that you'll of course want to be familiar with NYS regulations - a read of the sepic code is a good place to start.

    The difference is that MA teaches the underlying theory that better equips us to spot trouble while the NYS regulations are the minimum standard that is enforced here.

    Here is a collection of links to stuff from NY that you'll want to read.

    About your question of what is a "phase 2 septic inspection" - it depends.

    See SEPTIC INSPECTION LEVELS for a start.

    About your question: "What do blackwater assessments consist of?"

    Let's start by reading the following, then let me know of any questions or suggestions you have after seeing those guidelines.

    Finally, when you're ready, be sure to give us your contact information so that we can list ou as a New York State septic inspector found via

    On 2019-06-13 by (mod) - code for distance from main drain line to leach lines

    No Kelly that distance is specific to the site design, slope, changes in elevation, etc.

    On 2019-06-12 by Kelly

    Is there specific code of the required distance (or max distance) of the line between the main drain line to the leach lines?

    if in response to written notice from you that there is an open septic tank, and the observation that this risks a fatal Hazard should someone fall into the tank, the property owner is still not going to take immediate action cure this unsafe and unsanitary condition you may have no choice but to ask for help on their health department. Meanwhile keep people away from the area as it is unsafe.

    On 2017-09-28 by Carrie

    I am in a rental (house). The septic tank needed to be emptied. When the tank was uncovered, the lid was broken and part of it was gone. I can't get the rental company to come out and address this issue. The open tank is still uncovered and this is close to a residential road. How can i get the rental company to come out and get this problem fixed as i feel it is a major safety issue. It has been 2 weeks now.

    What were the NJ Codes for Septic Systems in 1996

    On 2017-03-28 by (mod) -

    Dawn:

    First: you need an inspection and perhaps testing of the condition of the septic tank AND the effluent disposal system - a drainfield, leachfield, soakaway bed, or similar term depending on where you live. Important in that process is a finding that the system is safe - that is, for example that the tank cover doesn't risk someone falling into the tank (a quick death).

    Next: if the existing system is not usable you'll need a new septic system sized by an engineer as adequate for your food service business, and you'll need the system design and capacity to be approved by your local building department. Or if the existing system is functional you'll need to document its capacity and have that approved for your use for your business.

    Finally: IF you need to abandon a septic tank you don't usually have to dig it up - unless there were really no other place to put the new tank. Even then a septic contractor may have other options depending on the tank type (example: a steel tank might be just crushed and buried alongside a new tank in the same spot).

    I have a industry existing septic tank, built in 1982. Do I have to dig it up and put a new one in to start a food service business.

    I live in a rural area the neighbors septic tank has a beeper on it that goes off everyday... it is so irating is there anyone I can complain to about this issue? Is it unsafe?

    On 2016-09-02 by Anonymous

    No, Donna in fact septic tank depth requirements vary widely by type of system and climate. There in fact some systems that are completely above ground.

    There are of course recommendations depending on the specific type of system and on site conditions.

    On 2016-09-02 by Donna Deerwester

    Is there a code for the depth of the lid to the tank?

    On 2015-11-12 by (mod) -

    Continuing,

    Simply placing dec I rate bricks over the lid of a concrete septic tank outside is harmless and not prohibited by any code I've seen.

    On 2015-11-12 by (mod) -

    I'd sure love to see your bank's federal law citation as I think someone was speaking loosely. Septic tank regulations where you live will come from your state or province and cannot specify every odd thing people might dream up. Certainly "decorative bricks" aren't named.

    However

    1 you don't want to put a septic tank inside of a building as a sewer gas explosion could occur and there are health concerns.

    2 you don't use a septic tank to support a structure

    3. Walking or sitting on a septic tank could be fatal if the cover is not adequate regardless if other concerns.

    On 2015-11-12 by Laura

    I am buying a house were the septic system lid was used as a small floor with decorative bricks on top, even though the systems operates well and maintenance is appropriately given. The bank tells me that by federal law, the septic system cannot have any thing built on top and that I have to remove the bricks, if not they will not approve the loan for the house. Is this true? Do decorative bricks qualify as violating federal law if anyway the septic system has a cement lid?

    I live in Sherburne County, old farm house rental. the landlords upgraded in 1996. how do I get the whole system checked and tested? they choose not to.

    You can hire a private home inspector who includes septic system visual inspection, component locaiton, and septic drainfield loading and testing in their services. A few plumbers or septic installers or engineers may also offer that service.

    Note that in some states septic system inspection, testing, or soil tests such as perc testing must be performed by a licensed expert.
