# Tempered Water > Tempered Water means water having a temperature range between 80 and 110 degrees Fahrenheit. **Term:** Tempered Water **Last updated:** 2026-07-29 ## Definition ## What Tempered Water Means in a Contract Tempered Water, as used in a contract, describes water that has been deliberately regulated to fall within a defined temperature range, commonly stated as between 80 and 110 degrees Fahrenheit. Rather than referring to hot or cold water generally, the term signals a controlled, moderated output intended to avoid the risks associated with scalding or excessively cold water at the point of use. This distinction matters because a contract that references Tempered Water is typically imposing a specific technical or safety obligation on one party, often a contractor, facilities operator, or equipment supplier. The concept most frequently surfaces in agreements tied to building systems, plumbing installations, or industrial processes where water temperature directly affects safety or product quality. When a contract defines Tempered Water with a numeric range, it converts what might otherwise be a vague expectation into an objective, verifiable standard that both parties can rely on for compliance and dispute resolution purposes. Because the term carries a precise technical meaning, parties drafting or reviewing a contract should treat it as a defined term rather than an ordinary descriptive phrase. Its presence usually indicates that the underlying subject matter, whether a building, a piece of equipment, or a manufacturing line, has specific regulatory or safety considerations attached to water temperature. ## How Tempered Water Is Defined or Measured The standard definition anchors Tempered Water to a numeric temperature band, most commonly 80 to 110 degrees Fahrenheit. This range is intended to be warm enough to be functional for handwashing, eyewash stations, or safety showers, while remaining cool enough to prevent burns or scalding injuries. Contracts that adopt this definition typically expect the range to be maintained consistently at the point of delivery, not merely at the source. Measurement is usually accomplished through mechanical mixing valves, thermostatic controls, or automated monitoring systems that blend hot and cold water supplies to achieve the specified output. A contract may require periodic testing, calibration, or certification to confirm that the temperature range is being met, particularly where the water serves a safety function such as emergency eyewash or shower equipment. - Thermostatic mixing valves are commonly specified as the mechanism for achieving compliance. - Testing intervals and acceptable tolerance levels may be included alongside the temperature range. - Recordkeeping obligations sometimes accompany the technical requirement, allowing verification during audits or inspections. ## Where Tempered Water Appears in Agreements Tempered Water provisions most often appear in construction contracts, facilities management agreements, and equipment supply or installation contracts. In these settings, the term establishes a performance obligation tied to plumbing systems, safety equipment, or process water used in manufacturing. It can also appear in leases or service agreements where a landlord or contractor is responsible for maintaining building systems to a defined standard. Industries with heightened safety or hygiene requirements, such as [manufacturing](https://www.genieai.co/industry/manufacturing) and [healthcare](https://www.genieai.co/industry/healthcare), are particularly likely to include Tempered Water clauses because water temperature can affect both worker safety and regulatory compliance. In construction agreements, the term frequently ties into broader plumbing or mechanical specifications referenced in schedules or technical appendices attached to the main contract. Service level agreements covering ongoing facilities maintenance may also reference Tempered Water as part of the operator's continuing obligations, with failure to maintain the specified range treated as a breach or a trigger for remedial action. ## Why the Exact Wording Matters Because Tempered Water is a technical term tied to a numeric range, small differences in wording can materially change the obligations of the parties. A contract that fails to specify the exact temperature range, or that references an ambiguous standard such as. ## Context ### Relevant circumstances - Water supply for facilities agreements - Manufacturing processes where water is symptomatic - Compliance with health and safety regulations ### Relevant sectors - Manufacturing - Healthcare ## Relevant contract types - [Real Estate Contract](https://www.genieai.co/en-us/template-type/real-estate-contract) - [Real Estate Purchase Agreement](https://www.genieai.co/en-us/template-type/real-estate-purchase-agreement) - [Real Estate Sale Contract](https://www.genieai.co/en-us/template-type/real-estate-sale-contract) --- This is the Markdown representation of [https://www.genieai.co/en-us/define/tempered-water](https://www.genieai.co/en-us/define/tempered-water), provided for AI agents and crawlers.
