Septic Log

A maintenance record for a septic system. You log what your service provider did and the sludge and scum levels they measured; Septic Log checks the numbers for things that cannot be true and tells you when the next inspection and pump-out are due, using the intervals the US EPA publishes.

1. See it work - no signup

This is a real record with three events, already checked. Look at the numbers and the printed record:

What it catches

What you enteredWhat it says
Sludge 30 in + scum 20 in in a 40 in tankimpossible - two layers cannot be deeper than the tank
Top of the sludge layer 11 in from the outletflagged - under the 12 in the EPA names as a pump-out trigger
Solids 31% of the liquid depthflagged - over the 25% the EPA names as a pump-out trigger
An inspection dated next yearrejected - a visit cannot be logged before it happens
Two pump-outs 40 days apartflagged - the EPA range is three to five years; likely a duplicate
Last inspection 4 years agoflagged - the EPA says inspect at least every three years

What it will not do

It will not tell you whether your system is compliant with any local, state or federal code - only the authority with jurisdiction can do that. It does not measure anything: the sludge and scum levels are the numbers your provider reports. There is no AI judging anything here. It is dates and arithmetic, and the intervals come from the one page quoted on every result.

2. Then get a free key - 20 service events/month, no card

Recommended next step. An email address is all it takes. The same key keeps working if you ever move to a paid plan.

3. Keep going - free

Checking a record is free and anonymous (3/day). The free key keeps working month after month. If you ever reach its monthly limit, the API says so and links to the options - nothing is charged without you.

Where the dates come from

Straight from the EPA page on caring for a septic system - the same page for everyone, quoted verbatim in the machine-readable description and on every result:
