Features of the Wells and Intakes Listing

Your facility may have one or more wells or surface water intakes listed on the first page of the Water Inventory form. On the other hand, there may be no wells or intakes listed, or all of the sources may be sealed or unused. However, we are just as interested in the amount of water you purchase. Please indicate the amount you purchase in the second part of the Water Inventory form, which addresses water use.

 

Explanation of Terms

 

Well/Intake      Each well or surface water intake is listed in this column by number and sometimes by a “pet” or local name. If there is a combination of wells and intakes, the intakes are numbered starting with 1 after the well listings. Intakes will also not have a depth associated with them.

 

Status              The status or condition of the well. Our most common categories include In-Use, Emergency, Disconnected, Capped, Abandoned, and Sealed.

 

Twn                 Township in Public Land Survey System used to locate well or intake.

 

Rng                 Range in Public Land Survey System used to locate well or intake.

 

Sec                  Section in Public Land Survey System used to locate well or intake. May include 10-acre plot designation (1A, 2B, etc.).

 

Depth              Depth of well. Surface water intakes do not have a depth associated with them.

 

Max Daily         This figure is the greatest daily pumpage or withdrawal from the well for the whole year. It does not mean the largest capacity of the well if run constantly for a 24-hour period.

 

Total Annual    This figure is the total number of gallons pumped from a well or surface water intake for the entire year.

 

Note on recirculated water: Many commercial-industrial facilities use recirculated or diverted water for different purposes. An electrical power plant may use water from a lake or river for cooling purposes, then return the water to its source. A quarry may pump water from a pit, use the water for processing and washing, and then return most of the water to a settling pond. A conservation facility may divert water from a lake or river to flood an area and create waterfowl habitat for a certain period, and then return the water to its source after that period of time. In your accounting of withdrawals from surface water sources, please enter the total amount of water withdrawn or diverted. The second part of the form has a space for noting the amount of water recirculated during the year.
