How to Fill Out the Water Use Part of the Inventory Form

Facilities in the IWIP database are categorized as to type:

Depending on your type of facility, the number of questions will vary, from four questions to eight questions.

Public Water Supplies

  1. If you withdrew water from your own wells or surface water intakes, enter the figure in "Total Finished Self-Supplied Gallons." If you bought water from another facility during the specified year, enter the figure in "Total Finished Purchased Gallons." Add the two figures to get the "Grand Total Finished Gallons."
  2. Provide the population directly served within city limits and outside city limits.
  3. If you purchased water, indicate the supplier.
  4. Enter the number of residential services and the number of gallons of water used annually by residents.
  5. Enter the number of commercial services and the number of gallons of water used by those services. Note: Commercial services are nonmanufacturing entities. Examples include truck stops, car dealerships, small businesses, car washes, roller rinks, restaurants, etc. Also include municipal uses in this category.
  6. Enter the number of industrial services and the number of gallons of water used annually by those services. Note: Industrial services are manufacturing entities, such as fertilizer plants, soybean processing plants, and other types of factories.
  7. Indicate whether your facility sells water to another public water supply system. If yes, provide the name(s) of systems to which you sell, and indicate how much water was sold to each system. Include bulk water sales in this category.
  8. Unaccounted-for-Flow: Subtract the total billed/metered amount of water from your total finished gallons.

Commercial-Industrial Facilities

1.    Enter the "Total Annual Gallons Purchased" or "Total Annual Gallons Withdrawn" on the top line of the two columns.
A. Processing/Washing Enter the annual water amounts purchased or withdrawn in each column.

B. Cooling & Condensing Enter the annual water amounts purchased or withdrawn in each column. If appropriate to your facility, also indicate the type of cooling system, amount discharged to a stream or to the atmosphere, and the amount of consumption (incoming water minus the amount discharged).

C. Boiler Feed Enter the annual water amounts purchased or withdrawn in each column.

D. Employee/Sanitary Enter the annual water amounts purchased or withdrawn in each column.

E. Hydroelectric Flows Enter the annual water amounts purchased or withdrawn in each column.

F. Other (Recirculated water, irrigation, etc.) Enter the annual water amounts purchased or withdrawn in each column.

2.   Supplier of Purchased Gallons Indicate the name of the supplier.
3.    Average number of employees, patrons, etc. daily Indicate a daily average (not a yearly total)
4.    (Power Generation Stations) Your total annual power generation during (the specified year): Enter the number for Net Generation and Gross Generation. For clarity, circle or check the unit (kilowatt, megawatt, or millions of kilowatt-hours).

Conservation and Fish & Wildlife Facilities

  1. Total: Indicate the annual water amounts purchased or withdrawn for the specified year.
  2. Other (fowl flooding, etc.): Indicate the annual amount used for the special purpose. Please circle or write in the use.
  3. Average number of employees, patrons, etc. daily: Please indicate a daily average, not a yearly total.
  4. Supplier of Purchased Gallons: Indicate the supplier.

Irrigation

Forms for irrigation facilities include a section called "Calculating Water Withdrawals." The best way to gauge your withdrawals from a well or a pond are with an hour meter or a flowmeter. The next best way is to keep a record of how long each pump is operated during the irrigation season. If you know the pumping rate and the number of hours operated, use the formula Pump Rate X Hours Operated X 60 to determine Total Gallons. One other method is to multiply the total number of inches of water applied by your total irrigated acres, which will give you acre-inches. Then multiply by 27,154 to get total gallons.

Enter the following in the "Total Water Use and Breakdown" section:

  1. Total: Indicate the annual water amounts purchased or withdrawn for the specified year. In A, B, and C, indicate the amounts used for Irrigation, Domestic Use, and any special purpose.
  2. Supplier of Purchased Gallons: Indicate the supplier.
