Our editorial aim is to make water bill information useful, understandable, and traceable to its sources. Calculator pages should help visitors identify the rules behind an estimate and the limits of that estimate.
Topics and audience
WaterBillCalc focuses on US household water consumption, unit conversion, water and sewer estimates, and explanations of utility billing. We write for readers who want practical guidance without having to interpret a long tariff alone.
We use plain language, descriptive input labels, and short explanations. We define unfamiliar units and identify when a calculation needs a specific billed volume rather than raw meter consumption.
Source standards
For city rates, the preferred sources are the utility’s adopted schedule, official rate table, or a government publication. Search summaries and unofficial articles can help locate a document, but they do not override an adopted schedule.
Pages should identify the rate period, supported customer type, and a link to the source. A proposed rate must not be presented as an adopted current rate. A document can be official yet still be outdated or apply to a different class.
Content and calculator development
We use AI-assisted tools for drafting, coding, and organizing content. AI is a production aid, not an authority for rates or billing rules. Statements about rates need sources, and code needs calculation checks.
The website does not claim an independent expert panel or professional certification. The relevant review is a check of source claims, implementation, examples, labels, and stated limits. Important gaps should be explained or the unsupported feature should not be offered.
Accuracy and useful limits
We aim to include the rules that materially affect the supported estimate, such as tier boundaries, fixed fees, minimum charges, or sewer multipliers. Exclusions should appear near the tool when they could affect a user’s result.
We do not imply that a generic calculator reproduces every city’s bill. A city page should not silently use a national default, assume every meter has the same fee, or treat an example as a typical household measurement.
Independence and commercial relationships
Source selection and correction decisions should follow evidence rather than a payment or promotional request. Utility references do not imply a partnership or endorsement.
If advertising, affiliate links, or sponsorships are introduced, relevant disclosures should be clear. Paid relationships should not be used to alter verified rates or hide a material calculator limitation.
Updates and corrections
A published rate period and source-check date help readers judge whether a page matches their bill. They are not a promise that the utility has made no later changes. Reports or newly discovered official schedules can trigger review.
Material errors should be handled under our Corrections Policy. When a source conflict cannot be resolved, the page should explain the uncertainty or limit the affected feature rather than guess.
Reader contributions
Readers can suggest topics, identify confusing labels, or report official rate changes. Send the URL, relevant source, and a clear description to contact@waterbillcalc.com. We do not guarantee publication of every suggestion.
We should not publish a reader’s identifying information or private bill without permission. An error report can inform a correction without identifying the person who sent it.
