Test results are usually good for two to five years, and in some cases can be renewed. However, with all things perc, rules vary greatly from town to town so don’t make any assumptions. Always check with the town health department before proceeding.
Do perc tests expire?
The short answer is that you have to do the perc test in the location of the drain field in order to get a septic system permit. Also, perc test results expire after 2-5 years in most locations, so you may need to retest or pay a fee to update the results when you are ready to build.
Do perc tests change over time?
Steve Bliss, of BuildingAdvisor.com, responds: A perc test measures the rate at which water is absorbed (percolates though) the soil. The time of year can definitely affect perc test results as well as the level of the water table, which is also a concern.
How long is a perc test valid in MA?
Percolation testing may be conducted at any time of the year and the data obtained in accordance with the procedures specified by 310CMR 15.000 may be deemed valid for an indefinite period of time provided the soils within the site tested remain undisturbed and unaltered.
How do you know if land will perk?
In most jurisdictions, a perc test is performed when an official from the county health department meets with the owner of the property and/or a licensed excavator to dig a hole and test the drainage rate of the soil on-site (they literally pour water in a hole and time how long it takes to drain through).
What is the alternative to a septic tank?
The major alternatives to septic tanks include mound, aerobic septic, and cesspool systems, as well as sander filter, constructed wetlands, and drip irrigation. The mound system is most popular for soil that is too shallow over bedrock or for a water table which is too high.
What is a good perc rate?
A good perc rate for a septic system is between 1 and 30 minutes per inch. Between 30 and 60 minutes per inch might require hydraulic analysis for installing a septic system. Anything under 1 minute per inch or over 60 minutes per inch is not an ideal perc rate.
When is the best time to do a perc test?
For the best results, you should perform a perc test in the driest season. During this time, the water table will be at its lowest point, and the dry soil will more readily absorb liquid. However, if the soil is frozen or has recently absorbed a lot of rain or melted snow, the percolation results will be lower.
How much does a septic tank cost?
On average, the cost of installing a new septic tank system is $3,900. The price ranges from $1,500 to $5,000 for a typical 1,250-gallon tank, which is an ideal size for a three- or four-bedroom home. This cost is inclusive of the tank itself, which costs $600 to $2,100 or more, depending on the type.
Can you do a perk test in the rain?
Ideally, a percolation test will be performed when the ground is saturated, or just following a significant rain storm. If it has not recently rained, you may want to repeat step 3 before conducting the experiment.
How many bedrooms can a 1500 gallon septic tank have in Massachusetts?
Existing approved design flow shall be used to determine potential number of bedrooms. Systems with a leaching area designed for 1000 gallons shall be approved for a maximum of 5 bedrooms with a 1500 gallon septic tank, 4 bedrooms with a 1000 gallon tank.
How much does it cost to perk land?
Perc testing typically costs between $750 and $1,850, according to HomeAdvisor. However, that is just one portion of the testing cost. You may need to conduct additional tests before building, such as a deep hole test or a seasonal high water table test, which will add to the total soil testing cost.
How much does a perk test cost in MA?
The cost of perc test that meets all local requirements for a septic or drainage system permit can range between $300 and $1,000 or more depending on the lot size and conditions.
How deep is a perc test?
Test holes should be 30 cm (12″) square or 36 cm (14″) round and excavated to the proposed depth of the absorption field (or as instructed by the designer). It is generally easiest to dig a larger hole part way down, then dig a 18 to 20 cm (7 to 8″) deep accurately sized test hole in the base of the larger hole.
Can you have a septic tank without a leach field?
Though you can not have a septic system without a leach field, you do have options when it comes to choosing the type of septic system installation. The following list is not all-inclusive, but does include the common types of septic systems: Conventional System. Chamber System.
Is a perc test the same as a soil test?
The two main tests used to determine a site’s suitability for a septic system are a perc test and visual observation of the soil in a test pit, sometimes referred to as a deep hole test.
