Private Well Water Testing Records

Who it is for
Anyone on a private drainage system — septic tank, cesspool or package treatment plant.
How to use it
- Record the tank type, capacity and where the access covers are.
- Log every emptying with the contractor and the waste transfer paperwork.
- Note sludge depth or condition if the contractor reports it.
- Use the warning-signs list at each check.
What is on the sheet
2 pages, in this order:
Page 1
Printed under the title: Emptying, inspection and maintenance record for a septic tank or package treatment plant. The two questions after a failure are always when it was last emptied and by whom.
Local rules vary. Rules for septic systems differ sharply between countries, states and counties — emptying intervals, discharge rules and registration are all local. Check what applies where you are; this sheet records what you did, it does not tell you what is required.

Questions
How often does a septic tank need emptying?
It depends on tank size, household size and system type, and in some places it is set by local rules. Ask your contractor what interval they recommend for your tank and record it here.
Do I need to register a septic tank?
In several countries and states, yes — private drainage is regulated, and rules on discharge and registration vary by area and change over time. Check with your local authority or environment agency.
