Water & wastewater

We manufacture engraved identification for water and wastewater treatment facilities across the United States — identification for treatment plant equipment, pipe markers, valve tags, non-potable water warnings, panel labels, and room signage. Our identification is engraved from durable phenolic or metal materials selected for long-term exposure to treatment plant conditions.

Water and wastewater treatment facilities operate for decades. Identification specified during construction remains in service through multiple maintenance cycles, staff turnover, and equipment upgrades. Engraved identification maintains legibility across those timelines without repainting, replacement, or peel-off failure that adhesive labels can experience in treatment plant environments.

We have manufactured engraved compliance identification since 1982 from Chico, California. We produce identification from your project drawings, specifications, label schedules, and applicable utility engineering standards. For contractors and engineers working on multi-site municipal water and wastewater projects, we can maintain your specifications on file for consistent identification across future work.

What we manufacture

What We Manufacture for Water & Wastewater Facilities

Water and wastewater treatment facilities require identification across many equipment and infrastructure categories. We manufacture engraved identification for:

  • Pipe markers and pipe identification — Engraved pipe markers per ANSI/ASME A13.1 formats, sized per 10 States Standards guidance
  • Valve tags — Brass valve tags with engraved valve numbers, contents identification, and directional information
  • Equipment identification and nameplates — Engraved equipment nameplates per your facility's numbering schema and drawing schedule
  • Panel labels — Control panel identification, motor control center labels, PLC panel identification
  • Non-potable water identification — Engraved non-potable water warning placards and identification plates
  • Room and building signs — Engraved room identification, equipment room signs, chlorine room warnings, access identification
  • Clarifier and process equipment identification — Engraved identification for clarifiers, pumps, blowers, filters, and process equipment
  • Lift station identification — Wastewater lift station equipment identification, control identification, warning placards
  • Chemical storage identification — Engraved identification for chemical storage areas per facility hazard communication requirements
Categories

Water & Wastewater Identification Categories

Treatment facility identification breaks into predictable categories that engineering firms, contractors, and facility teams specify during design and reference during operation and maintenance. We manufacture engraved identification for these categories:

  • Process pipe identification — Contents identification, flow direction arrows, color-coded per applicable state or facility standard
  • Water treatment process equipment — Clarifiers, filters, chemical feed pumps, disinfection equipment, monitoring equipment
  • Wastewater treatment process equipment — Grit chambers, aeration equipment, secondary clarifiers, digesters, disinfection equipment
  • Facility infrastructure — Pump stations, lift stations, valve boxes, control buildings, chemical storage buildings
  • Safety and warning identification — Non-potable water warnings, chlorine warnings, confined space identification, arc flash labels per NFPA 70E
  • Regulatory identification — Identification supporting state, county, and municipal water and wastewater regulations

All identification is manufactured from your project drawings, specifications, label schedules, and applicable state or facility engineering standards.

Non-potable water

Engraved Non-Potable Water Identification

Non-potable water identification is required at water treatment facilities and any installation where non-potable water sources exist alongside potable water. We manufacture engraved non-potable water identification for treatment plants, industrial facilities, and municipal installations — including engraved warning placards, pipe identification, hose bib identification, and outlet identification.

Our engraved non-potable water identification is manufactured from phenolic or metal materials that maintain legibility through outdoor exposure, wash-down cycles, and treatment plant conditions where adhesive labels can peel or degrade. Identification is engraved to your project specifications and applicable pipe marking standards.

For adhesive vinyl stickers, printed decals, or stock non-potable water labels, we recommend working with your project's signage supplier — our capability is engraved identification manufactured for long-term treatment plant service.

Built to your spec

Standards We Support

Water and wastewater treatment identification operates under multiple standards. Our engraved identification is manufactured consistent with:

10 States Standards

"Recommended Standards for Water Works" and "Recommended Standards for Wastewater Facilities," published by the Great Lakes and Upper Mississippi River Board (GLUMRB) and adopted or used as baseline by most U.S. states.

ANSI/ASME A13.1

Scheme for the Identification of Piping Systems (pipe marker sizing and format standard).

NFPA 70E

Arc flash labels for electrical equipment at treatment facilities — see engraved arc flash labels.

State-specific standards

State environmental and water/wastewater regulations vary; we manufacture identification per your project specifications and applicable state requirements.

HazCom 2012

Hazard Communication Standard context for chemical storage identification.

Applicability of specific standards to your facility depends on your state, jurisdiction, and project requirements — confirm with your project engineer and applicable regulatory agency.

Materials we engrave

Materials

We manufacture water and wastewater identification from durable materials selected for treatment plant service:

  • Phenolic materials — Two-color and three-color engraving stock rated UL 94 flame ratings, available in over 40 color and thickness combinations
  • Brass — Durable brass for valve tags, equipment identification, and nameplate applications
  • Aluminum — Aluminum nameplates for equipment identification, panel labels, and warning placards
  • Stainless steel — Stainless steel identification for high-humidity, wash-down, and corrosive service environments

Material selection depends on your installation environment, exposure conditions, and project specifications. For chemical exposure environments, we recommend confirming material compatibility with your project chemistry.

How it works

Our Process

Every water and wastewater identification order follows the same production process:

Project intake

Send us your project drawings, specifications, label schedules, and applicable engineering standards. For contractors and engineers managing multi-site municipal water and wastewater projects, we can maintain your specifications on file for consistent identification across future work.
Step 1

Quote and specifications review

We review your specifications, confirm material selection for your installation environment, and quote your order.
Step 2

Proof approval

First orders receive a proof for your approval before production begins. Reorders match the approved layout on file — no proof cycle required, no risk of specification drift across future work.
Step 3

Production and shipping

Compliance tags produced every business day from Chico, California. Your identification ships to your project site or facility on your requested schedule.
Step 4

For treatment facility projects with phased construction or ongoing maintenance identification needs, we can produce identification against your project timeline — new construction, retrofits, and repair replacements from the same specifications.
