Signs your septic system needs attention

Water and sewage from toilets, drains or sinks backing up into the house
Bathtubs, showers and sinks draining very slowly
Gurgling sounds in the plumbing
Standing water or damp spots near or over the septic tank or drainfield (leach field)
Sewage odors around the tank or drainfield
Bright green, spongy, lush grass over the tank or drainfield, even in dry weather

Seeing more than one of these?

Several fixtures draining slowly at once, or sewage odor indoors, points to the system rather than one clogged drain. Get help before it turns into a backup.

How often to pump a septic tank in Harwich

The US EPA says household septic tanks are typically pumped every three to five years, and the average household system should be inspected at least every three years by a septic service professional. Systems with pumps, float switches or other mechanical parts (common with nitrogen-reducing I/A systems) should generally be inspected once a year.

How often your tank needs pumping depends on four things EPA lists: household size, total wastewater generated, the volume of solids, and tank size. EPA's rule of thumb: pump when the bottom of the scum layer is within 6 inches of the outlet, the top of the sludge layer is within 12 inches of the outlet, or sludge and scum make up more than 25% of the liquid depth.

Local guidance on the Cape can be more frequent. The Harwich Ponds Coalition advises having a licensed hauler pump every 2 to 3 years, and the Town of Yarmouth's Health Division recommends every 3 to 4 years. Ask your provider what fits your tank and how your home is used. A summer rental with full houses every week is not the same as a two-person year-round home.

What is different about septic on Cape Cod

MassDEP calls nitrogen pollution, mainly from septic systems, an ongoing problem for Cape Cod's bays and estuaries. Because of that, Cape septic rules now go further than the rest of the state.

2023 Title 5 nitrogen rules

On July 7, 2023, MassDEP changed Title 5 (310 CMR 15.000) to create Natural Resource Nitrogen Sensitive Areas on Cape Cod: watersheds with an EPA-approved nitrogen limit (TMDL). In those areas, if a town does not pursue a Watershed Permit, existing systems must be upgraded to nitrogen-reducing technology (such as an Innovative/Alternative, or I/A, system) within a 5-year timeline, and new construction must use nitrogen-reducing systems. A town that files a Notice of Intent for a Watershed Permit pauses those requirements. Barnstable County notes that homeowners who installed an I/A system in the past 10 years do not have to upgrade until it fails or the local approving authority requires it.

Harwich specifics

Harwich shares the Pleasant Bay watershed with Brewster, Chatham and Orleans. Those four towns were the first in Massachusetts to receive a Watershed Permit. MassDEP keeps a status table of Watershed Permit filings by Cape town and watershed. Whether your address is affected depends on its watershed, so check with the Harwich Health Department (508-430-7509).

Septage haulers working in Harwich need an annual permit from the Board of Health. Under the town's septage regulations they must provide a waste report for each system they service. The Health Department publishes the current licensed hauler list.

Frequently asked questions

How often should a septic tank be pumped?

The US EPA says household septic tanks are typically pumped every three to five years and systems should be inspected at least every three years. Local Cape guidance is often shorter: the Harwich Ponds Coalition suggests every 2 to 3 years. The right interval depends on household size, water use, solids and tank size.

Is this a septic company?

No. Harwich Septic Help is a free referral service. We connect you with independent, licensed local septic providers, who may pay us a referral fee. The provider you are connected with does the work and sets the price.

Do I need a Title 5 inspection to sell my house in Harwich?

In most cases, yes. Massachusetts Title 5 generally requires a septic system inspection within 2 years before a sale, or within 6 months after if weather prevents it before closing and the seller notifies the buyer in writing. Some transfers, such as between spouses or parents and children, are exempt. Only MassDEP-approved System Inspectors can do a valid inspection. Harwich also has a local Real Estate Transfer Regulation: as published by the town, the inspection should happen 30 to 180 days before the transfer, and the inspector must also have passed the Harwich Board of Health exam. See our Title 5 page for details.

What should I do if sewage backs up into my house?

Avoid contact with the sewage, stop using water so less flows into the system, and call a septic professional. EPA advises contacting your local health department for guidance and wearing protective gear such as long rubber gloves during cleanup.

How do I know a septic hauler is licensed in Harwich?

The Town of Harwich Health Department publishes a list of licensed septic haulers and can be reached at 508-430-7509. Septage haulers working in Harwich need an annual Board of Health permit.

Do the 2023 Cape Cod nitrogen rules mean I must replace my septic system?

Not automatically. The 2023 Title 5 changes apply in designated Natural Resource Nitrogen Sensitive Areas on Cape Cod. Towns can file for a Watershed Permit, which pauses the 5-year upgrade requirement for homeowners. Check with the Harwich Health Department or the MassDEP address lookup to see if your property is affected.
