When you're looking at a Piperton home or lot, ask early where the wastewater goes. Some homes are on individual septic, some are on one of the city's decentralized systems, and some are on lines that end at a treatment lagoon in the Town of Rossville. Which one applies affects your monthly bill, whether a tap fee could come up later, and more and more how many new lots Piperton can approve over the next two years.
The scarce resource here is sewer capacity, not land, and the city's 2026 meeting minutes show how little of it is left.
Where Piperton's wastewater actually goes
Piperton doesn't run its own sewer treatment. At the May 19, 2026 Board meeting, City Manager Steinbach said the city buys sewer capacity from Rossville and buys its water from Collierville, because that is "good business without getting into the water and sewer business."
The arrangement goes back to a 2015 agreement. Rossville has fewer than 1,600 residents, but it built a 2.5 million gallon lagoon, sized up because Kellogg's was there. That left extra room, and Piperton has rented part of it. Piperton also has a plant of its own, the Adair wastewater treatment plant. It was built but never finished, and the city has kept it maintained and mothballed because it "didn't have the critical mass and still don't have the critical mass." In its June 1, 2026 inspection report, TDEC said Piperton's SBR plant was not operating and wastewater was going to Rossville.
Septic and decentralized systems are how much of Piperton grew in the first place. Steinbach said the original subdivision was built on subsurface septic. He said decentralized sewer later made it possible for Ridgewood Grove, Greenbrier, Twin Lakes, and Shaw's Creek on Raleigh LaGrange to develop. TDEC's station list is slightly different. It names Twin Lakes, Shaws Creek, LaGrange Pointe/Madeline Farms, and Fisherville Road, and notes that Fisherville wasn't running yet because no homes had been built there. Because the two lists don't match, confirm the service for any specific street with the city. Don't rely on either list alone.
The summer's numbers against an 80,000-gallon ceiling
Piperton's allowance with Rossville is 80,000 gallons per day. Public Works Director Mr. Mills reports each month how much of it the city used.
| Month reported | Flow sent to Rossville | Average per day | Share of 80,000 gpd allowance |
|---|---|---|---|
| June 2026 Board meeting | 2.2 million gallons over 29 days | 76,000+ gpd | 95.04% |
| July 2026 Board meeting | 2 million gallons over 30 days | 67,000 gpd | 83.91% |
| August 2026 Board meeting | 2.3 million gallons over 32 days | 72,000 gpd | 90.67% |
The June figure may be inflated. When Steinbach asked about it, Mills said a crew was "searching out and destroying I&I" and that the work would take time. TDEC's April 27 inspection measured a smaller transfer, about 57,956 gallons per day. Those figures cover different periods and can't be compared directly. Still, every monthly report this summer came in above 80% of the cap.
The deadline is what makes this matter for buyers. In May, Steinbach said that once Piperton consistently goes over 80,000 gallons, "that clock starts ticking. Two years to get this done." He added that if development continues at its current pace, the city could go over that line "in less than a year."
Three ways out, each with a price
The May minutes lay out the city's options in its own words.
- Buy more room from Rossville. On April 16, Rossville sent a proposal to raise Piperton's capacity from 80,000 to 400,000 gallons per day. Its terms included an $800,000 annual reserve-capacity fee. Commissioner Townsend noted that per-1,000-gallon rates would also go up under the proposal, and Steinbach answered, "yes absolutely."
- Finish the Adair plant. A design paid for with American Rescue Plan money put the renovation at $8 to $9 million. Steinbach said the city couldn't reasonably carry that debt "without increasing the rate to our residents and customers by more than 100%."
- Build a lagoon. City crews suggested using both facilities at roughly half the cost of renovating Adair. The Board approved up to $10,000 for Wauford & Company Consulting Engineers to study the idea.
The first two options cost about the same. Steinbach put it this way:
"In ten years, we could pay for said wastewater treatment plant that I said we couldn't afford."
He was also clear that Rossville was acting reasonably. He thanked the town for considering the request and said Rossville has its own concerns about saving capacity for its future growth, which he said would be his priority too in their position.
As of late September, none of the three has been settled. At the June 9 budget meeting, the lagoon analysis was described as one that "should be in process." Rossville's August 11 minutes don't record a counteroffer or a new agreement with Piperton.
What this means for the lots on the table now
New subdivisions keep coming before the city while this is unresolved. In June, the Planning Commission gave final plat approval to Blue Sky Communities' Prestonwood Phase 1 on 18.98 acres. The plan includes open space, trails, and a pavilion with a pickleball area. The plat says 55 lots. The development contract the Board approved in July, with $167,578 in listed fees and a $100,000 surety, describes 54.
Piper Hollow's Phases 3 and 4 add 20 and 19 lots. At the July hearing, residents raised concerns about cut-through traffic, construction vehicles speeding, and whether the Commerce Road access would be gated. Those phases were supposed to come back on September 8. According to the minutes, the developer wanted to meet with residents first.
None of those approvals record a condition about sewer capacity. The rules for future applications are changing, though. The city has been rewriting its subdivision regulations to require an infrastructure concurrency report that includes water and sewer calculations. Staff said the goal is "to make sure we know our infrastructure will support development." Whenever the city is closer to its sewer cap, that report will have more weight in what gets approved. If you're waiting for a later phase or a new community, plan for the possibility that approvals take longer.
The bill side is on the agenda right now
On September 15, the Board's agenda included a water and sewer rate study by RateStudies, Inc. It also included Ordinance No. 424-26 and Ordinance No. 425-26, which would replace the current water and sewer rate ordinances, plus an increase to garbage and yard-waste fees. Minutes from that meeting hadn't been posted when this was written. The new rates, whether the ordinances passed, and when any change takes effect are all still open. Ask the city for the current schedule before you budget.
Rossville changed its own sewer rates on July 1, 2026. The minimum is now $16.87, plus $4.79 per 1,000 gallons. The public record doesn't show whether those charges apply to what Piperton pays, so they shouldn't be read as a Piperton rate.
Water is under pressure too. In his August Board report, Mills said Piperton had purchased 20 million gallons of water for the month, and he said a penalty applies above 18 million. He also credited the sprinkler schedule with keeping the water tower from running low, after several near-misses the year before. The city's August notice sets watering days by address. A September 2 notice asked residents to cut back on nonessential water use while the drought continued.
Questions to settle before you write an offer in Piperton
- Is the home on individual septic, a decentralized city system, or a line that drains toward Rossville? Get the answer in writing from the seller or the city.
- If the home is on septic and city sewer is extended nearby later, could a tap fee apply? The May 19, 2026 Board minutes say the sewer-use ordinance doesn't affect homes on septic where no city sewer is available, but that a tap fee could apply where sewer is extended.
- What are the water and sewer rates as of your closing date, and did Ordinances 424-26 and 425-26 change them?
- For new construction, does the builder's lot already have its approvals, or is it in a future phase that still needs Planning Commission review under the new concurrency rules?
- Has the city reported anything new on the Wauford lagoon study or on talks with Rossville?
FAQ
Is Piperton stopping new home construction? No. The records reviewed show no moratorium, and Prestonwood and Piper Hollow were both moving through review this summer. The city manager has said capacity has to be solved within about two years once flows consistently go over 80,000 gallons per day.
Will my sewer bill go up? That depends on what the Board did with the RateStudies findings and Ordinance 425-26 on September 15. Those results weren't public when this was written. In May, the city manager said either expansion option would put upward pressure on rates.
Does any of this apply to homes on septic? Day to day, mostly not. City staff said the sewer-use ordinance doesn't reach septic homes where city sewer isn't available. A tap fee could come up if sewer lines are extended to the property later.
If you're comparing a Piperton lot with options in Collierville or across the state line, the sewer question belongs in the same conversation as price and commute.
