Copper phone lines are disappearing, costs are surging, and your lift station auto dialers are running on borrowed time. Here’s what’s happening and what to do about it.
If your lift stations still rely on POTS (Plain Old Telephone Service) lines for alarm monitoring, you’re not alone. For decades, copper phone lines were the backbone of lift station communication—connecting auto dialers to operators when pumps failed, water levels spiked, or power went out.
But that backbone is crumbling. And the timeline to replace it is shorter than most utility operators realize.
What’s Actually Happening with POTS
The FCC has been clearing the path for telecom carriers to retire copper-based phone networks for years. But in 2025, the transition shifted from gradual to urgent:
- AT&T stopped accepting new POTS orders on October 15, 2025, covering 1,711 wire centers across 18 states. No new lines, no changes, no additions.
- Costs are surging. POTS lines that cost $30–$65 per month a few years ago now run $200 to over $2,700 per month in some areas—with no cap in sight.
- The FCC’s July 2025 rulemaking removed most procedural barriers for carriers wanting to discontinue copper service, clearing the way for faster shutdowns.
- AT&T plans to phase out copper entirely by 2029, with half of its TDM services targeted for discontinuation by 2027.
Bottom line: POTS isn’t being slowly phased out—it’s being actively shut down. If your lift stations depend on copper phone lines today, you’re operating on infrastructure that carriers are walking away from.
Why This Hits Lift Stations Especially Hard
Lift stations are critical infrastructure. They pump wastewater from lower to higher elevation so it reaches treatment plants. When a lift station fails undetected, the consequences are immediate and serious: sewage overflows, environmental violations, EPA fines, and public health risks.
Traditional POTS-based auto dialers were designed for a different era. They call a single number when an alarm triggers. If the line is degraded, if the call doesn’t connect, if the operator misses it—there’s no backup. No text. No email. No dashboard. Just silence while wastewater rises.
Now layer on the POTS sunset:
- Copper line quality is deteriorating as carriers reduce maintenance on infrastructure they plan to abandon
- Alarm calls are less reliable on aging networks, meaning the one call your auto dialer makes may not get through
- Monthly line costs are consuming budget that could fund actual infrastructure improvements
- Carrier discontinuation notices could arrive with as little as 180 days to migrate—and lead times for replacement equipment are already stretching to 6 months
The Real Cost of Staying on POTS
Let’s put numbers to it. A utility managing 30 lift stations with POTS lines at even $150/month per line is spending $54,000 per year just to maintain phone lines—lines that only call out on a single alarm and provide zero visibility between alarms.
At the higher end of current POTS pricing ($300+/month), that same utility is looking at over $100,000 annually for a monitoring method that was state-of-the-art in the 1990s.
Every dollar spent keeping a POTS line alive is a dollar not spent on pumps, pipes, and the infrastructure your community actually depends on.
Cellular Managed SCADA: The Modern Alternative
The replacement for POTS at lift stations isn’t another phone line—it’s purpose-built cellular monitoring designed specifically for water and wastewater infrastructure. Mission Communications pioneered the cellular managed SCADA concept for the water industry over two decades ago. Today, more than 4,000 utilities across the U.S. and Canada rely on Mission’s systems for real-time lift station monitoring. Here’s what makes the approach different:
- Real-time visibility, not just alarms. Mission RTUs report every 2 minutes or on a 5% level change—giving operators constant insight into wet well levels, pump runtimes, and system health, not just a phone call when something goes wrong.
- Multi-path notifications. Alarms reach operators via phone call, text, email, and web dashboard simultaneously. No single point of failure.
- No infrastructure to manage. Mission’s managed service handles the cellular connectivity, the software platform, and the data hosting. There are no radios to program, no carrier contracts to negotiate, and no servers to maintain.
- Fast deployment. Mission RTUs install in hours, not weeks. Plug into existing sensor wiring, power up, and the station is online.
- Emergency backup pump control. The MyDro 150 and 850 can temporarily take over pump control if the primary controller fails—keeping the station running while repairs are scheduled.
Utilities Are Already Making the Switch
This isn’t theoretical. Utilities across the country have already replaced POTS with Mission’s cellular SCADA—and the results speak for themselves:
- Lenawee County, Michigan deployed Mission RTUs across 40 lift stations, reducing site inspections, catching equipment problems faster, and saving both time and manpower.
- Renewable Water Resources (ReWa) in South Carolina replaced their dial-up phone systems at pump stations with Mission units for increased reliability across their entire collection system.
Don’t Wait for the Dial Tone to Go Silent
The POTS sunset isn’t coming—it’s here. Carrier discontinuation notices are going out. Costs are climbing. And the window to migrate on your own timeline, rather than under emergency pressure, is narrowing.
If you’re managing lift stations on POTS lines today, the most important step you can take is to understand your options before the decision is made for you.
