# 1 Septic System Maintenance Tip

New Septic Systems and replacement septic tanks in Massachusetts are being constructed with a filter device that is inserted into the Septic tank outlet tee. There is supposed to be a cover to the finished ground surface (the cover is bolted down to avoid unauthorized access). There are multiple companies that manufacture these outlet filter devices. These filter devices are typically the same and serve the same basic function, which is to help prevent solids from leaving the Septic Tank and entering the leaching system. A premature failing of the leaching system can occur when soilds and grease are allowed into the leaching system. The filter is simply inserted into the outlet tee.

This filter must be cleaned as part of your septic system maintenance.

Septic Tank outlet filter & Manhole Cover

 

The Massachusetts Sanitary Code requires the installation of a manhole access cover extended to the final ground surface over the outlet of the Septic tank when an outlet filter is installed. This manhole cover eliminates the digging & searching for the Septic Tank outlet. For safety reasons, these manhole covers are bolted, so you will need a wrench to remove the bolts before opening the cover.

How to clean the Septic Tank outlet filter

The septic tank outlet filter should be cleaned at least once every year and when the septic tank is pumped.

To clean the septic tank outlet filter, you will need rubber gloves, tools to open the manhole cover and a garden hose.

WARNING: this maintenance work will expose you to sanitary waste, so if you have health issues, hire a sanitary pumping company to do this maintenance work. ALSO, do not touch your face or eye when you are doing this job.

Are you ready?

1.   Put on the heavy rubber gloves and un-bolt the manhole cover. Remover the cover.

2.   Reach into the septic tankand grab the handle of the filter.

3.   Pull the filter up and out, keeping it above the open septic tank.

4.   Use the garden hose to spray wash teh scum off the filter and back into the Septic Tank.

5.   Reinsert the filter back into the outlet. BE SURE to have the arrow pointing toward the direction of the outlet pipe.

6.   Put the manhole cover back on (align the bolt holes) and tighten the bolts (don’t over tighten them!).

7.   Remove the rubber gloves (most people will throw them away and take them off by turning them inside-out to avoid touching the outside of the gloves). You should disinfect the end of the garden hose and then wash your hands with pleanty of soap & water

 Why do I need to clean the outlet filter?

The Septic Tank outlet filter blocks material from flowing out of the tank and into the leaching system. Eventually the filter device will collect too much material and the filter will plug up with solids. When that happens, the effluent water is prevented from leaving the Septic tank. If the water can not leave the septic tank, it will back-up into the house. Depending on your home plumbing, a Septic Tank back-up could cause a nasty mess.

Septic System Construction – Do you need an Engineer?

Wednesday, January 6th, 2010

The local Board of Health has approved the plans for your Septic System; you have accepted a bid from a contractor and you are ready to start construction.

Do you need an engineer?

If you are working in Massachusetts, the answer is Yes!

The State Sanitary Code under Section 310CMR15.021 actually defines what your Engineer needs to do during the construction of the Septic System.

Here is a listing of the Tasks that your engineer needs to do.

Task 1 – The engineer needs to observe and confirm the initial excavation of the system area.

Task 2 – The engineer needs to observe the construction / installation of the system components (Septic Tank, Distribution Box & Leaching System).

Task 3 – Prior to the contractor back-filling the system, the engineer needs to take measurements of the constructed system components (location and elevation) to confirm that the components were installed in accordance with the approved plan.

Task 4 – The engineer needs perform additional measurements when a system has grading to prevent “break-out” in order to confirm that the grading was constructed properly.

Task 5 – The engineer needs to prepare an “as-built” plan for the constructed system and submit the “as-built” plan to the local approving authority (Board of Health for example) along with a form that clearly states that the system has been properly constructed.

During these tasks, the local Health Agent also visits the construction site to make observations of the work progress.

The contractor also has to submit a form stating the construction of the system has been properly completed.

Once all these tasks are done, the local approving authority can issue the Certificate of Compliance.
