New septic in Attleboro

It may look like a big sand box, but actually there is a leaching field underneath this sand.  Since the leaching field is above natural grade, a rubber liner is installed around the entire leaching field to prevent the breakout of any waste water.  This particular septic system install which is in Attleboro was a bit more complicated.  The tank and pump chamber are located next to the house which is about 150′ away from the field.  A pump sends the waste water through a 2″ pipe from the pump chamber to the distribution box (small box in the above picture) which is located at the beginning of the leaching field. 

100_1020This is a picture of a Distribution Box during a Title 5 inspection in Mansfield.  Since the liquid level is above the invert of the outlet pipe, the result would be a failing Title 5 Inspection.  The heavy solids in the Distribution Box were caused by a missing outlet tee in the septic tank.  When you have your septic tank pumped, be sure your pumper inspects all aspects of your tank or you may have some bad news coming your way when you have a Title 5 inspection done.

We took advantage of the great weather last week and installed a septic system that included a 1500 gallon tank, a 5 outlet distribution box with baffle and an 18′ x 40′ stone and pipe leaching field.  Over the last few years the majority of septic systems we have installed have been plastic leaching chambers covered with sand, but we are seeing a trend of many engineers switching back to the old stone and pipe systems.  No matter what type of leaching field the septic plan calls for we highly recommend installing a vent pipe.  The vent pipe adds oxygen to the leaching field, which in turn helps the bacteria in the leaching field work more efficiently.  We paint the exposed pvc pipe black or green and recommend that a bush or stone be put in front of it.  There are other products such as bird baths, granite posts and fake boulders that are made to fit over the pipe and no one will ever know it is there.

100_0984This title 5 inspection in Attleboro went extremely well for us and the home owner.  When a property has a nice lawn we do everything we can to keep it that way.  We removed the sod first, placed all the dirt on a tarp, examined the d-box and finally put everything back the same way we found it.

Mass Title 5 Inspection

Posted by: | Comments (0)

Our latest title 5 inspection in Norton passed by the skin of its teeth.  The Distribution box had moderate solid carryover and moderate to heavy concrete corrosion.   A zabel filter was added in the tank to minimize solid carryover in the future.  The concrete corrosion is normal for a system of this age.  Even though there was heavy corrosion, the d box was still structurally sound and showed no signs of leakage.100_0978

100_0881Here is an example of a perfect looking distribution box.  This d-box was opened up on one of our recent title 5 inspections in Norton.  If you have to do a title 5 inspection on your septic system, this is what you want to see.

100_0873No solids should ever enter the distribution box, if they do you could have some serious and expensive problems on your hands.  This distribution box was encountered on a title 5 inspection and due to the solids and high water level it was a title 5 failure.  The most common way solids would get into the distribution box would be a missing outlet tee or never having your tank pumped.

100_0857100_0856In order to pass a title 5 inspection in Massachusetts the leaching field can’t be located in the water table.  The distribution box shown above passed with flying colors, but the leaching field itself is dangerously close to being in the water table.  We hand dug a hole near the leaching field and found standing water at 46″ and estimated the bottom of the leaching field to be 43″.  This is too close of a measurement to pass or fail the title 5 inspection, so the town of Norton heath inspector recommended that a hole be excavated and report be filed by a soil evaluator.  This will give us an accurate reading of the water table and a correct verdict on this Title 5 dilemma.

100_0849Today we finished installing a septic system in Attleboro, MA.  The picture above is of a Distribution Box and a distribution box riser.  Title 5 requires that a riser be installed on the distribution box to bring access to the d-box within 6 to 9 inches of finished grade.  This makes accessing the distribution box extremely easy during a title 5 inspection or if the d-box has to be found due to a leaching field problem.

Corroded Distiribution Box

Posted by: | Comments (0)

100_0847Here is an example of how the concrete reacts to septic gases over the course of many years.  If you look closely at the picture, you can see how the concrete is just falling apart.  The walls of the D-Box are made of 2″ thick concrete and this Distribution box is so badly corroded that I could push a screw driver through the 2″ thick concrete wall with no effort at all.  In order to pass the title 5 inspection the Distribution box must be replaced.
