The Cost of Operating a Water Powered Sump Pump

How much does it cost to run a Basepump water powered backup sump pump? Let’s take a look…

Basepump water powered sump pump cost
In a home with 90 PSI water pressure, Basepump models use 1 gallon of city water to remove 2 gallons of sump pit water, the most efficient water use of any water powered pump on the market. Because Basepump is a backup pump that only activates during emergencies, the total water usage over the long run is minimal.

To give a sense for the potential cost of running the pump during a heavy storm, here is an extreme example:

If you own the highest volume Basepump model (the CB1500 or CB1500-AVB) and during a very heavy storm, the Basepump ran every 5 minutes, in 30 second cycles, for an entire 24-hour day, that makes for 288 cycles. Each of those 30 second cycles could have used up to 7.5 gallons of city water.

According to the EPA, the U.S. national average cost of water is $0.002 per gallon. So, multiplying 288 cycles, by 7.5 gallons per cycle, by a water cost of $0.002 per gallon, your cost to operate the pump would only be $4.32 during that 24 hour period.

Keep in mind, this is an extreme example. In many cases your pump would run much less and your operational cost would be even lower. Also, if you have a lower capacity Basepump model than the pump we used in the example (the largest Basepump), your cost would be significantly lower.

In general, your water powered sump pump’s operational cost is likely to be similar in magnitude to the electrical cost for running your primary sump pump. Both costs pale in comparison to the expense of repairing even a tiny amount of water damage in your basement, let alone the cost of redoing a finished basement ruined by a complete basement flood.
