Spring Hill Sewer Moratorium
What the current capacity framework says, what it does not say, and how to check a parcel before you buy, design, or build.
What is the current Spring Hill sewer moratorium?
Spring Hill remains under a TDEC consent-order framework that restricts new sewer connections without qualifying rights or allocation. Ordinance 25-29, adopted January 5, 2026, allocated remaining capacity and conditionally reopened development processing. It does not automatically require septic. Verify sewer status with the city and septic feasibility with the correct county authority.

What changed in January 2026?
The August 2025 consent order restricted sewer connections for projects without vested rights. Spring Hill later paused portions of development processing while it measured remaining plant capacity. On January 5, 2026, the board adopted Ordinance 25-29 and replaced that broad pause with a one-time capacity-allocation framework.
The allocation numbers show how tight the math is. Ordinance 25-29 calls itself a one-time allocation of all remaining treatment capacity: 207,403 gallons per day for existing development agreements, 62,500 gallons per day for 250 permit-ready vacant lots, 65,000 for critical infrastructure, and a 100,000-gallon discretionary reserve that Ordinance 26-01 later amended. Allocated projects must install flow meters. The ordinance states plainly that no additional development capacity remains available.
Read that carefully: per the city, the ordinance lifted prior suspensions only for applications that can proceed under the framework, and it did not announce unlimited sewer availability. Read the city's framework summary and the current ordinance index.
How did the Spring Hill sewer moratorium develop?
Spring Hill self-reported 29 wastewater-treatment-plant effluent exceedance violations, according to the city's official summary.
The Board of Mayor and Aldermen accepted TDEC Consent Order WPC2025-0093. The order restricted new sewer connections for projects without vested sewer rights.
The city temporarily suspended and then extended parts of development processing while staff evaluated remaining wastewater capacity and an allocation method.
The board adopted Ordinance 25-29 on second reading. It established a one-time sewer-capacity allocation framework and lifted prior development suspensions only as allowed by that framework.
The city's ordinance index lists Ordinance 26-01 as an amendment to Section 2F of Ordinance 25-29 concerning the sewer-capacity reserve.
The city says the original order followed 29 self-reported effluent exceedance violations between 2023 and 2025. Its August 2025 notice also says the consent-order moratorium remains until the treatment plant meets specified performance standards for 12 consecutive months.
Does this mean a Spring Hill lot needs septic?
No. A sewer restriction is not septic approval. First establish whether the parcel has vested or allocated sewer capacity. If it does not, ask the city what wastewater paths are allowed for the proposed use. A conventional or alternative septic system still needs suitable soil, enough area, the correct TDEC or county permit, an approved design, and land-use approval. Some parcels will not support either the assumed sewer connection or the proposed septic design.
Which authority should you call?
Maury County parcel
TDEC administers the SSDS permit. Use its regional contact page, approved soil-consultant list, online application, and active-installer lookup.
Williamson County parcel
Williamson is a TDEC contract county. Use the county program for septic questions while still confirming Spring Hill's separate sewer and development requirements.
Before you close on land near Spring Hill
- Confirm the parcel number, city limits, and whether it lies in Maury or Williamson County
- Request written sewer-availability and allocation status from Spring Hill
- Ask whether any vested right runs with the parcel, project, agreement, or current plan
- Read the applicable section of Ordinance 25-29 and later amendments
- If septic is being considered, obtain the existing record and a current soil evaluation
- Make the contract contingent on the wastewater solution and house size you will actually accept
- Price pumps, treatment, service contracts, access, and electrical work if the design is not gravity
- Do not clear, grade, or set a house pad before the approving authorities confirm the sequence
What are the realistic paths for an affected parcel?
A project may proceed with documented vested or allocated city sewer capacity, wait for later capacity, use a city-approved decentralized approach where available, or pursue an individually permitted septic system if the site and land-use rules allow it. Each route runs through a different authority, so a contractor cannot swap one for another mid-project.
For a Maury County septic route, start with a soil and site evaluation and the TDEC permit process, then compare the permitted system's installation and ownership cost. Building new? The new-construction septic guide sequences the whole thing. Spring Hill's city limits cross the county line, so never assume the same septic office handles two nearby addresses.
Research and review. The Maury Septic editorial team checked this guide against current TDEC rules and service pages, plus Spring Hill's consent-order notices, adopted framework, and current ordinance index. Private-market costs are identified as planning ranges. For a specific property, rely on the issued permit and a written contractor scope.

What do property owners ask about Spring Hill sewer and septic?
Is the Spring Hill sewer moratorium still in effect?
Yes. The restriction remains part of the current framework. Ordinance 25-29 allocates remaining capacity and allows certain development processing under that framework. The city's current ordinance index also lists Ordinance 26-01, which amended the sewer-capacity reserve. Confirm a parcel directly with Spring Hill before relying on any summary.
Does the sewer moratorium mean I must install septic?
No. It means you cannot assume a new city sewer connection is available. A parcel may have vested or allocated sewer capacity, may need an approved decentralized option, may qualify for a TDEC-permitted septic system, or may not support the proposed project. City and TDEC approvals are separate decisions.
Who is affected by the Spring Hill sewer moratorium?
The 2025 consent-order summary says the connection restriction applies to projects without vested sewer rights. Ordinance 25-29 then created allocation groups and enforcement rules for remaining capacity. Because rights attach to specific projects and parcels, ask the city for written confirmation rather than inferring status from an address or nearby construction.
Who permits septic systems on the Maury County side of Spring Hill?
TDEC administers Subsurface Sewage Disposal System permits in Maury County. Spring Hill also extends into Williamson County, which TDEC lists as a contract county with its own program. Confirm the parcel's county first, then use the correct septic authority and the city's separate land-use process.
