Why does Pennichuck need to test the water meter at my home?
The New Hampshire Public Utilities Commission requires Pennichuck to periodically test every one of its meters. This ensures meter accuracy.

The entire test takes about 60 minutes. There is no cost to you, the customer. Your cooperation in this testing process is absolutely necessary for us to comply with NHPUC regulations. So, when you receive a post card requesting you to call the Customer Service Department to make an appointment- your assistance is essential. Thanks in advance for helping us.

How is my bill calculated?
Your water bill consists of a customer charge (based on meter size) and a consumption charge (based on the reading obtained from your water meter). The reading is calculated in units and is shown on your bill under “consumption”. Units are calculated in 100 cubic feet (CCF) or 1,000 gallons and billed either monthly or quarterly, depending on your system.

Why do I have to pay a minimum charge every month, whether or not I use any water?
The service charge portion of your bill is designed to recover a portion of the fixed costs incurred in providing water service. These costs include the cost of maintaining the supply, treatment, distribution and service facilities that are needed to provide water service to your home or business. This charge appears on every bill and does not vary with consumption, but is related to the size and flow capacity of your meter.

How is my water usage calculated?
Most water meters record usage in units of 100 Cubic Feet.*
1 Unit (100 Cubic Feet) equals 748 Gallons

To find out how much water you used in any given period:
Just subtract the reading on your last bill 5693    
From the current meter reading - 5521    
100 Cubic Feet
To convert to gallons:
Multiply your usage 172  
100 Cubic Feet
By 748 x 748
Gallons per 100 Cubic Feet
Gallons Used

* For most 5/8” residential meters only the first four digits are used in calculating usage since the meter records in cubic feet and we bill for 100 cubic feet.
