Rate Matters [Abstract]
Rate Matters	9.  Rate Matters From time to time, the Company files applications for rate increases with the PPUC and is granted rate relief as a result of such requests.  Most recently, the PPUC authorized an increase in rates effective March 1, 2019. The PPUC permits water utilities to collect a distribution system improvement charge, or DSIC.  The DSIC allows the Company to add a charge to customers' bills for qualified replacement costs of certain infrastructure without submitting a rate filing.  This surcharge mechanism typically adjusts periodically based on additional qualified capital expenditures completed or anticipated in a future period.  The DSIC is capped at 5% of base rates, and is reset to zero when new base rates that reflect the costs of those additions become effective or when a utility's earnings exceed a regulatory benchmark.  The Company's earnings are currently below the regulatory benchmark allowing the Company to collect DSIC.  The DSIC provided revenues of $255 and $280 for the three and nine months ended September 30, 2021, respectively, and revenues of $0 for the three and nine months ended September 30, 2020.
