Product Description
Detectable Tech Company is a manufacturer of non potable water warning tape for buried reclaimed water, irrigation reuse, and purple non-potable utility line identification. This purple PE underground warning tape is placed above the pipeline during trench backfill, so excavation crews can see the warning layer before reaching the actual line. It can be produced as non-potable water line marking tape with legends such as Caution Non-Potable Water Line Below, with width, thickness, roll length, and detectable structure confirmed before production.

Benefits
- Helps crews identify buried non-potable, reclaimed, and irrigation reuse water lines more quickly.
- Purple color direction supports correct separation from potable water marking systems.
- PE film construction works well as a non-adhesive warning layer during trench backfill.
- Black printed legends stay easy to recognize when the warning layer is exposed.
- Detectable and non-detectable versions can be matched to the locating method required on site.
- 24-72 hour reference handling checks can review print rub, edge tearing, and roll release behavior.
- Typical width tolerance can be controlled around +/-1.5 mm for steadier trench coverage.
- Typical roll length tolerance can be controlled around +/-2 percent for easier project quantity planning.
- Carton and pallet labels can show project name, size, color, and wording to reduce jobsite mix-ups.
Applications
- Reclaimed water distribution line identification
- Non-potable irrigation utility line marking
- Landscape reuse water pipeline projects
- Municipal reclaimed water trench backfill
- Golf course and park irrigation reuse systems
- Purple non-potable utility line warning
- Waterworks construction requiring PE underground warning tape above buried lines
- Projects using printed warning tape for reclaimed irrigation service lines
Product Overview
Non potable water warning tape is made for projects where reclaimed water and irrigation reuse lines must be clearly separated from drinking water systems. It is not a general water pipe tape. The product is designed as purple reclaimed water warning tape for non-potable service lines, landscape irrigation reuse, municipal reclaimed water systems, and similar utility trenches where color and wording need to be correct from the start.
The tape is supplied in non-adhesive PE roll form and is installed above the pipe during backfill, not wrapped around the pipe itself. For projects that only require a visible warning layer, 4 mil or 6 mil PE film is commonly selected. For non-metallic lines that also need locator response, a 5 mil detectable version with an aluminum core can be used. Before packing, production checks normally include purple color consistency, print clarity, roll edge flatness, winding tension, and smooth unwinding from the outer layer to the roll core.
The printed legend should follow the utility drawing or project specification. Common wording includes Non-Potable Water Line Below, Caution Buried Non-Potable Water Line Below, or Reclaimed Water Line Below. Before bulk production, it is better to confirm the wording, tape width, film thickness, roll length, black letter height, and print repeat spacing. These details help reduce site confusion, wrong excavation, and accidental cross-connection during later maintenance work.
When should the purple color and printed legend be confirmed?
Purple color and printed wording should be confirmed before bulk production, especially when the tape will be used for reclaimed water, irrigation reuse, or non-potable water line marking tape requirements. The final legend should match the project drawing, municipal utility requirement, and trench marking practice. For larger waterworks projects, it is also worth checking tape width, film thickness, roll length, black letter height, repeat spacing, carton label information, and whether a detectable core is needed. A pre-production sample can be reviewed for color match, print sharpness, roll edge condition, and smooth unwinding.
How should non potable water warning tape be placed during trench backfill?
This tape is normally placed above the buried reclaimed water or irrigation line during trench backfill. It should not be used as pipe wrap. The purpose is to create a visible warning layer that appears before the excavation reaches the actual pipeline. For shallow trenches, a narrower roll may be enough. For deeper or wider trenches, a wider tape gives better visual exposure across the backfilled area. If the line needs locator response, detectable tape can be selected. If the project only needs a visual warning layer, non-detectable PE tape is usually enough. Clean roll edges and stable winding also matter because uneven rolls slow down installation work in the trench.
FAQ
What is non potable water warning tape used for?
It is placed above buried reclaimed water, irrigation reuse, and non-potable water lines to warn crews before they reach the pipeline.
Can the tape be printed with project wording?
Yes. The warning legend, repeat spacing, and letter height can be adjusted to match the approved utility drawing.
Should I choose detectable or non-detectable tape?
Choose detectable tape when locator response is required. Choose non-detectable PE underground warning tape when only a visual warning layer is needed.
What details should be checked before bulk production?
Confirm purple color, printed legend, width, thickness, roll length, detectable structure, sample appearance, roll edge flatness, print clarity, and carton label information.
