UPDATE • 2025 WATER REPORT
Alliance water-quality results are now inside My Aquifer
Key results include arsenic 5.47 ppb, nitrate-nitrite 5.23 ppm, and lead 0.997 ppb at the 90th percentile.

This is a public High Plains aquifer monitoring well, not a measurement directly beneath your home or field. A 2025 statewide report also identifies roughly 133 ft of predevelopment-to-2025 decline just north of Alliance in Box Butte County.

August: alternating Group 169 may be controlled twice a week; Everyday Group 168 may be controlled every day except Sundays/holidays; Group 167 has no control in July or August.
Public-data gap: PREMA explains that it manages against monthly kW peaks, but its public pages do not publish the actual monthly peak-kW series. V2 shows the live control signal and published rate/control rules instead of inventing a peak chart.

The annual summary states no violations occurred in 2025. The same report’s microbiological table separately notes one positive total-coliform sample in June and marks that row “Violations Present: Yes.” We show both statements rather than hide the discrepancy.

Quantity-management trigger framework: Phase II at ≥3 ft cumulative spring-static decline from the spring 1990 baseline; Phase III at ≥6 ft. Phase III makes regulated users subject to allocations.
Allocation varies by subarea. The 65-inch figure above is specifically the published 2025–2029 base allocation for subareas 4 and 6; it should not be assumed to apply to a field until its subarea is known.
Groundwater Quality Around You
Public groundwater context
Alliance-area samples — brought onto the page
Alliance’s public water supply is groundwater. Its 2025 report gives us a verified local groundwater-quality snapshot without pretending it is a test of your private well.

For a private-well subscriber, “around you” must stay honest: public area data can establish context, but only a sample from your own well can tell you what is in your well.

Your own laboratory test is the best evidence for what is in your well. Keep a private note here, then compare it with the public Alliance-area context.

Your Yard, By the Numbers
What replacing part of a lawn can mean in Alliance
≈ 623 gallons
1 inch of water applied across 1,000 sq. ft. of lawn
≈ $1.30–$2.25
Alliance urban water-use charge for that 623 gallons, depending on billing tier
1–1½ in./week
UNL summer lawn-water benchmark; actual need varies with weather and soil
The household case is bigger than the water bill. A long-term water-wise landscape study found homes with mostly xeric landscaping averaged about 2.2 fewer hours of yard maintenance per month and $206 less per year in direct landscape-maintenance spending than homes with mostly turf. These were study-period results from Southern Nevada, not a promise of Alliance savings.
Save water
Well-chosen native landscapes can reduce the need for supplemental irrigation once established.
Save money + time
Less lawn can mean less mowing, irrigation, fertilizer and other routine maintenance.
Reduce chemical inputs
Using less fertilizer and fewer pesticides reduces the amount available for runoff or movement through soil.
Protect the water beneath us. UNL reports that sustainable landscapes can reduce runoff and the movement of pollutants such as fertilizer and pesticides, while healthy roots and soil can help filter some pollutants and increase water infiltration.
Keep this in perspective: A single residential lawn is not the principal cause of Nebraska's groundwater contamination problems. The point is simpler: homeowners can reduce the water, fertilizer and pesticide inputs they personally control — and many households doing so can create a meaningful cumulative benefit.
Establishment matters: Newly planted native landscapes still require water, weed control and attention while becoming established. The larger water and maintenance advantages come after establishment.

How much lawn could you replace?
Enter the approximate square feet of lawn you might replace with native flowers, grasses or other water-wise landscaping.
≈ 623 gallons
water represented by 1 inch across this lawn area
≈ 623–935 gallons
water represented by UNL's 1–1½ inch summer weekly benchmark
≈ $1.30–$2.25
Alliance water-use charge represented by 1 inch, depending on billing tier
Replacing 1,000 sq. ft. of irrigated lawn could remove the need to apply this lawn-irrigation volume after the new landscape is established. Actual savings depend on rainfall, irrigation habits, plant choices and establishment needs.
Calculator basis: 1 inch of water over 1,000 sq. ft. ≈ 623 gallons. Alliance residential water rates used above are the local rates cited in this section. This is an estimate of lawn-irrigation volume and cost — not a guaranteed bill reduction.
