Video walkthrough explains how to use the De Minimis groundwater calculator
Summary
Amanda, the video presenter, demonstrates how to use the De Minimis calculator to estimate groundwater pumping and determine whether a parcel likely exceeds the 2 acre-feet-per-year de minimis threshold. She outlines required inputs, warns the parcel-wide estimate may overstate use, and notes the estimate is not collected.
Amanda, the video presenter, walks viewers through the De Minimis groundwater calculator and how to check whether a parcel pumps more than 2 acre-feet per year. The online walkthrough shows the sequence of questions and the inputs users should enter to produce an estimate.
The video opens with Amanda saying, "I'm Amanda, and this video is going to walk you through how to use the De Minimis calculator." She directs users unsure of their water use to the tool’s link titled “how do I know if I pump cumulatively more than 2 acre feet per year?” and identifies 2 acre-feet per year as the threshold the calculator is intended to help users evaluate.
Amanda demonstrates the first question the tool asks: "is groundwater being pumped for any other purpose than domestic use?" She instructs users who pump for business purposes to select "yes," and those pumping only for household use to select "no." After answering and clicking Next, the tool displays selected parcels and a list on the screen.
The presenter shows the next input fields: the number of households served on the property and the percentage of water use that is groundwater. She offers examples (50% or 75%) and uses 100% groundwater in her demonstration to produce an estimate.
Amanda explains that the calculator’s estimate "takes into account the entire parcel" and cautions that this will overestimate actual groundwater use if only a portion of the parcel is irrigated or served. She advises that if a user believes they use less than the estimate or "less than 2 acre feet per year of water, you can ignore this number and select the de minimis option." She also states the estimate shown is for the user's benefit and "we do not collect this information."
The video ends with Amanda returning viewers to the option-selection screen and closing, "Hope that helps." The walkthrough is procedural and aimed at helping landowners and household water users check whether they should claim de minimis groundwater use based on the tool’s parcel-level estimate.
