Well and septic: the one permit that is not municipal
Almost every permit you will ever pull on a house in Pennsylvania is issued by your township or borough. Wells and on-lot sewage are the exception, and they go the other way — to the county. Getting that backwards costs a week, and it is an easy mistake because it is the reverse of the rule that holds everywhere else.

The two offices
Your township or borough issues building, electrical, mechanical and plumbing permits under the state construction code, which over 90% of Pennsylvania municipalities administer themselves.
The county health department handles on-lot sewage permitting and well programmes. Montgomery County runs an equivalent office.
A project that touches both — a bathroom addition on a septic system is the standard example — needs both. They are separate applications with separate timelines, and one does not tell the other it has happened.
Who this applies to
More people than expect it. Public water and sewer thin out quickly north and west of the built-up corridor, and in Doylestown Township more than half of the roughly 6,000 households are on private wells.
Doylestown Township also has ongoing obligations that catch new owners out. Under Ordinance 299, adopted in 2001, septic systems must be pumped and inspected every three years, and well water must be tested for coliform and E. coli on the same three-year cycle. That is a standing requirement on the property, not a one-off at purchase.
When it comes up
Adding a bathroom or a bedroom. Both change the load a septic system is sized for. This is the most common reason a remodel turns into a county conversation nobody budgeted for.
Replacing or repairing a septic system. County, start to finish.
A new well, or abandoning an old one. Both are county matters, and properly sealing an abandoned well matters — an open one is a direct path from the surface into the aquifer your new well draws from.
Buying a house on well and septic. Ask for the pumping and testing records. Where an ordinance requires them on a cycle, they should exist.
The practical sequence
If your project touches the drainage side at all, go to the county first. A septic capacity question can change what you are allowed to build, and finding that out after the township has approved a plan means redrawing the plan.
The order that works: county for anything sewage or well related, then the township for the construction permit, then schedule the work. Doing it in that order costs nothing. Doing it in the other order occasionally costs the design.
One more thing about municipal permits
While you are at it, be aware that some municipalities add requirements of their own for the contractor rather than the work. Bristol Township, for example, requires annual contractor registration with the township plus registration with Keystone Collections. A contractor who works mainly elsewhere in the county may not hold it, which is worth establishing before they start rather than on the morning they cannot pull the permit.

Common questions
Do I need a county permit to replace a water heater on a septic system?
Usually not. A water heater replacement is a township permit under the construction code. The county becomes involved when the work affects the sewage system itself or the load on it — adding a bathroom or a bedroom, for instance, rather than swapping a fixture.
How often does a septic system need pumping in Bucks County?
It depends on your municipality as well as on the system. Doylestown Township requires pumping and inspection every three years under Ordinance 299, with well water testing for coliform and E. coli on the same cycle. Other municipalities set their own intervals, so check locally.
Can I add a bathroom to a house on septic?
Often yes, but it is a county question before it is a construction question, because an additional bathroom changes the load the system was sized for. Ask the county health department before the plans are drawn rather than after.

Short answer: almost always yes, and it is your township that issues it, not the county. What the regulation actually says, and the three-day rule for emergencies.
