Here is more information with tips to help pass a Title V inspection and what to do if it fails.
Will a 50 year-old system automatically fail? No, not as long as all components are working properly.
The first thing do is get in touch with a local engineer and the Board of Health. The engineer will determine if there is a "reserve area" on the original septic design where additional leach trenches can be added or whether another area is needed for a new system - in which case the engineer will draw up a "septic design" based upon soil testing that will be done.
The soil testing process consists of "perks and deep holes". The perk test will determine how quickly the soil leaches and the deep hole test will determine the level of the water table. Soils that have more gravel are better than those with clay and rock. A higher water table is not a good thing when it comes to septic systems as that requires a "raised system"; and your buyers will not want to find out that the beautiful, level yard they thought they were buying bought will now have a large mound in it -- another reason why Jim encourages you to get the Title V ordered and out of the way before you put your home on the market.
Once the septic system design is done and approved by the Board of Health you will want to get at least three bids by septic installers - estimates can vay greatly.
If you are already in the middle of a real estate transaction and find out your septic system has failed and that there is not enough time to repair or replace it before the closing, the bank giving the buyer the loan will require one of two things: 1) You to escrow 1.5 times the estimate to fix or replace the system - e.g. $30,000 if the repair will cost $20,000; or, 2) Delay closing unitl the installation is complete - yet another reason to get your Title V done and out of the way ahead of time!
If you find yourself in the position to have to replace your septic system and need financial help, contact the Massachusetts Housing Finance Agency (MHFA) at 617-723-0500. They have a manual online as well.
The Commonwealth of Massachusetts DOR provides a tax credit of up to $6,000 over 4 years to defray the cost of septic repairs. The credit cannot exceed $1,500 in any year and may be spread out over 4 years. The tax credit is limited to work done on a primary residence only. Use form Schedule SC.
If you have a cesspool will it automatically fail? State law does not require replacement of cesspools; although some towns will not pass a cesspool. Cesspools that exhibit signs of hydraulic failure, are located very close to private or public water supplies, or otherwise do not protect or pose a threat to the public health, safety, or the environment will need to be upgraded. Also, cesspools must be upgraded prior to an increase in design flow (e.g., the addition of a bedroom to a home.
An extremely important subject revolving around the Title V and septic systems is the proper representation of bedrooms in a home. The misrepresentation of legal bedrooms in the home will land you in court, and rightfully so. Septic systems are rated according their bedroom capacity. When someone says the septic system is "rated" for four bedrooms it means that the system will handle the waste generated by the occupants of four bedrooms.
In Massachusetts, It has nothing to do with the number of bathrooms in a home! Where everyone gets into trouble is, for example, marketing a home as a four bedroom when the septic system is rated for only three bedrooms. What you do in your house is one thing. How you advertise to a buyer is another. The buyer relies on what you say to make a buying decision and can sue for treble damages if what he bought is legally or technically not what you said he was buying.
There are certainly differences in market value between three and four bedroom homes regardless of the overall size of the house. If you have any doubt about the bedroom count your septic system is rated for, this information can be found at the local board of health or on the septic design. If a previous Title V inspection has already been done on the property, it can be found on that report as well.
So what if you decide not to sell? A Title V is good for two years from the date it is completed. It can be extended for a 3rd year if it is pumped in both years.
