Instead of sending obsolete meters to landfills, municipalities municipal meter recycling can recycle components such as brass, copper, aluminum, stainless steel, circuit boards, plastics, and glass. Proper recycling not only reduces environmental impact but also helps recover significant value through scrap metals while ensuring compliance with environmental regulations.
This guide explains everything municipalities, utilities, contractors, and public works departments need to know about municipal meter recycling—from collection and sorting to compliance, best practices, financial benefits, and frequently asked questions.
What Is Municipal Meter Recycling?
Municipal meter recycling is the systematic process of collecting, dismantling, processing, and recycling retired utility meters owned by local governments or public utilities.
These meters include:
- Water meters
- Electric meters
- Gas meters
- Smart meters (AMI)
- AMR meters
- Industrial meters
- Commercial meters
Instead of disposing of these assets, certified recycling facilities separate valuable materials and safely process hazardous components when necessary.
Why Municipal Meter Recycling Matters
Environmental Protection
Old utility meters contain recyclable metals and electronic components that should never be discarded in ordinary landfills.
Benefits include:
- Less landfill waste
- Reduced mining demand
- Lower greenhouse gas emissions
- Better conservation of natural resources
Resource Recovery
Many older meters contain surprisingly valuable metals including:
| Material | Common Use |
|---|---|
| Brass | Water meter bodies |
| Copper | Electrical coils |
| Aluminum | Internal components |
| Stainless Steel | Hardware |
| Iron | Frames |
| Circuit Boards | Smart meters |
| Glass | Meter covers |
| Plastic | Housings |
Recovered materials re-enter manufacturing supply chains instead of becoming waste.
Financial Benefits
Municipalities often recover value from retired infrastructure through:
- Scrap metal sales
- Commodity recycling
- Reduced disposal costs
- Lower landfill fees
- Revenue sharing with recyclers
Large smart meter replacement projects can generate substantial returns through recovered brass and copper. A recent municipal water meter replacement program in Plainview, Texas, diverted 88% of project waste from landfills and generated more than $140,000 through recycling.
Types of Municipal Meters That Can Be Recycled
Water Meters
Typically contain:
- Brass housing
- Bronze
- Stainless steel
- Plastic
- Glass
- Electronics
These are among the highest-value municipal meters due to their brass content.
Electric Meters
May include:
- Copper windings
- Aluminum
- Steel
- Glass
- Plastic
- Printed circuit boards
Older analog meters often contain significant recoverable copper. Some legacy models may also contain mercury switches that require specialized handling.
Gas Meters
Gas meters commonly include:
- Aluminum
- Steel
- Brass
- Cast iron
- Rubber seals
Proper processing ensures any residual gas hazards are managed safely.
Smart Meters
Modern AMI and AMR devices contain:
- Circuit boards
- Communication modules
- Batteries (in some models)
- Semiconductors
- Copper
- Plastics
Because they may store operational information or credentials, secure data destruction is an important part of recycling.
The Municipal Meter Recycling Process
1. Inventory Assessment
The municipality first identifies:
- Meter types
- Manufacturers
- Quantities
- Installation years
- Material composition
2. Collection
Retired meters are collected during:
- Infrastructure upgrades
- Smart meter deployments
- Routine maintenance
- Emergency replacements
3. Transportation
Certified recyclers transport meters under documented chain-of-custody procedures, helping utilities maintain accountability and audit records.
4. Sorting
Meters are categorized by:
- Water
- Electric
- Gas
- Analog
- Digital
- Smart
- Material type
5. Dismantling
Components are separated into:
- Brass
- Copper
- Steel
- Aluminum
- Electronics
- Batteries
- Plastics
- Glass
6. Hazardous Material Handling
Some older equipment requires additional care for:
- Mercury switches
- Batteries
- Electronic waste
- Oils
- Regulated components
These materials are processed according to applicable environmental regulations.
7. Material Recovery
Recovered materials are sent to processors where they become raw materials for new products.
Valuable Materials Found Inside Municipal Meters
Brass
Water meters are especially valuable because brass represents a high percentage of their total weight.
Applications include:
- Plumbing
