# Communication Pipe > Communication Pipe means a system, inclusive of necessary attachments, which convey water from the main to the consumer's premises **Term:** Communication Pipe **Last updated:** 2026-07-29 ## Definition ## What Communication Pipe Means in a Contract A Communication Pipe is the length of pipework, plus any necessary fittings such as stopcocks, ferrules, or joints, that conveys water from the public main to the point where it meets the private supply pipe on a consumer's premises. Contracts use this term to separate the section of infrastructure that a water undertaker typically owns and maintains from the section that becomes the property owner's responsibility once it crosses the boundary. The distinction matters because liability for leaks, damage, or repair costs often turns on which side of that boundary the fault occurs. In practical terms, a construction or infrastructure agreement will use Communication Pipe to describe a discrete physical asset with defined start and end points. The clause defining it usually sits alongside related definitions such as supply pipe, service pipe, or main, so that readers can trace the entire chain of water delivery from source to tap. Because the term describes something physical and locatable, its definition is often paired with drawings, plans, or schedules that show exactly where the pipe runs. ## How Communication Pipe Is Defined or Measured Most definitions of Communication Pipe describe it functionally rather than by exact dimensions. The core elements are that it conveys water, that it runs from the main to the consumer's premises, and that it includes attachments necessary for it to function, such as valves, connectors, or protective sleeving. Some agreements go further and specify a start point, typically the connection to the main, and an end point, typically the property boundary or a stop tap. Measurement in a technical sense usually appears in adjoining specifications rather than in the definition itself. These might reference pipe diameter, material standards, depth of installation, or pressure tolerances. When a contract incorporates technical schedules, the definition of Communication Pipe should be read together with those schedules to understand what physical standard the pipe must meet and how compliance will be assessed. - Start point: connection to the public water main. - End point: boundary of the consumer's premises or a designated stop tap. - Included attachments: fittings, valves, and connectors necessary for the pipe to function. ## Where Communication Pipe Appears in Agreements The term most commonly appears in agreements between water undertakers, developers, and property owners, particularly connection agreements, adoption agreements, and infrastructure agreements tied to new construction. It also shows up in easements and wayleave agreements where a pipe crosses land belonging to a third party, since the parties need to define exactly which section of pipework the easement covers. Beyond utility-specific contracts, the term can surface in broader development agreements, particularly in the
