What plumbing in Penngrove actually looks like
Penngrove is unincorporated, and that changes almost everything about the plumbing. There is no city utility here. Water comes from a private company or your own well, about half the community is on septic rather than sewer, and the building department is the county — not a city hall.
Two different water situations in one small town
Penngrove is served by the Penngrove Water Company, a privately owned utility regulated by the state. Inside the Penngrove Town District, the water it delivers comes from the Sonoma Water Petaluma Aqueduct. But the Canon Manor West area is supplied instead by two wells the company maintains. And outside those boundaries entirely, you are on your own private well — which means pressure tanks, well pumps, pressure switches and whole-house filtration are ours to look after, not a utility’s.
Half the town is on sewer. Half is not.
The Penngrove Sanitation Zone is a collection system only — about 475 acres and roughly 556 connections — and it pumps everything into the City of Petaluma’s system for treatment at Ellis Creek. It covers only part of the community. Properties outside the zone run on septic, permitted and regulated by Permit Sonoma. Knowing which side of that line you are on changes the answer to almost every drain question.
A sewer system built in the 1970s, and leaking
Sonoma Water says the Penngrove collection system was largely constructed in the 1970s and has significant inflow and infiltration — storm downspouts connected into the sewer, and groundwater entering through deteriorated pipe and joints. That matters to your wallet here more than most places, because Petaluma bills the zone by flow. Sealing a clean-out cap and disconnecting a downspout is not housekeeping in Penngrove; it is money.
The oldest housing stock around
Nearly one in five Penngrove homes predates 1940, another one in five went up in the 1960s, and about 62 percent was built before 1980 — the oldest profile of any community in this corner of the county. Original galvanized supply, aging well equipment and long-forgotten septic tanks are all in normal range here.
About wells and septic
If you are on a private well, your plumbing includes equipment a city customer never thinks about: the pump, the pressure tank, the pressure switch, and usually some form of treatment. We service all of it. On the septic side, Permit Sonoma puts it bluntly — Sonoma County’s soils are notoriously poor for septic systems. What we can do is keep what runs into it healthy: fix the leaking fixtures that overload a leach field, camera the line between house and tank, and stop the storm water that should never have been in there.
About permits
Penngrove is unincorporated, so building permits come from Permit Sonoma in Santa Rosa rather than a city. Water heater replacement requires a permit; wells and septic systems are handled by Permit Sonoma’s separate Well and Septic division. We pull the right one and meet the inspector — you do not chase it.

Penngrove plumbing questions, answered
Am I on city water in Penngrove?
No — there is no city here. Penngrove is served by the Penngrove Water Company, a private regulated utility. Inside the Town District the water comes from the Sonoma Water Petaluma Aqueduct; the Canon Manor West area is served by two company wells instead. Outside those boundaries, properties are on private wells.
Do you work on well systems and pressure tanks?
Yes. On a private well the pump, pressure tank, pressure switch and any treatment are all part of your plumbing, and there is no utility to call when they fail. Low or fluctuating pressure, short-cycling pumps and waterlogged pressure tanks are routine work for us out here.
Am I on sewer or septic?
It depends on the parcel. The Penngrove Sanitation Zone covers about 475 acres with roughly 556 connections and pumps into Petaluma’s system — but plenty of Penngrove sits outside it and runs on septic, permitted through Permit Sonoma. If you are not sure, we can usually tell from the clean-out and the site.
Why does my sewer bill go up after a wet winter?
Because the Penngrove zone is billed by flow into Petaluma’s system, and Sonoma Water has documented significant rainwater getting into that 1970s-era collection system — through downspouts tied into the sewer and through deteriorated pipe joints. Sealing your clean-out and disconnecting any downspout from the sewer is worth doing here.
Who issues plumbing permits in Penngrove?
Permit Sonoma, the county department — not a city building division, because Penngrove is unincorporated. Water heater replacements need one, and wells and septic go through Permit Sonoma’s Well and Septic division.
Do you offer same-day service in Penngrove?
Often, yes. Office hours are Monday to Friday, 7:30am to 4:30pm. Call and we will tell you the soonest we can be out.
