Two homes on the same private road in Anaqua Springs Ranch can share a builder, sit within a few dollars of each other per square foot, and still answer the question of where their water comes from and where their wastewater goes in completely different ways. One ties into San Antonio Water System pipes for both. The other runs on a private well and an aerobic septic system that Texas regulates more closely than most buyers expect. Neither the listing sheet nor the HOA statement will flag which one you are looking at. Lot position will.
That single variable, more than the median price or the HOA dues, is the detail worth settling before you write an offer on a specific address inside this community.
Why One Gate Doesn't Mean One Utility System
Across the Hill Country, from the Dripping Springs corridor through Boerne, limestone and caliche soils routinely fail the percolation tests that conventional gravity septic systems depend on. That is a documented reason aerobic treatment units are common throughout Bexar, Comal, Kendall, and Medina counties rather than an isolated quirk. Anaqua Springs Ranch sits on that same geology: limestone bluffs, wooded valleys, and the springs and creeks that gave the community its name, built out across roughly 920 acres in phases that stretch from the mid-2000s to current construction.
Where a SAWS main could reach a lot, homes there got municipal water. Where terrain, distance, or timing worked against it, homes still rely on private wells, and the sewer side often follows the same pattern with septic systems, aerobic units among them, standing in for a city sewer connection. Community guidance on this point is direct: confirm the water and sewer setup for a specific lot before you make an offer, because it varies by position within the gates rather than by phase, price, or builder.
This is not a defect. It is a working reality of building nearly a thousand acres of custom homes across uneven Hill Country ground. It just means the utility question belongs on your due diligence list with the same weight as square footage, not as an afterthought during option period.
The System That Comes With Paperwork
If the lot you are considering runs on a private well and septic, the next question is which kind of septic. Conventional gravity systems in Texas carry light oversight, including periodic pumping. Aerobic treatment units are a different commitment entirely.
Texas Health and Safety Code Section 366.0515 requires every aerobic system owner to maintain an active contract with a licensed maintenance provider, full stop. In Bexar County specifically, a new aerobic system's initial permit runs two years from installation. After that, the homeowner, not the builder and not the previous owner, becomes responsible for keeping a service contract in place and for the maintenance provider's filing inspection reports with the county, the local permitting authority. According to Septic Seeker, state rules layered on top require inspections roughly every four months, three per year.
Two practical consequences follow. First, Texas Property Code Section 5.008 requires sellers to disclose known defects in the septic system on the standard TREC disclosure form, so a documented history of missed inspections or a lapsed contract is something a buyer's agent can and should ask to see in writing. Second, Texas Septic Guide notes that a lapsed maintenance contract can delay a sale. SA TX Inspector reports that FHA, VA, and USDA loans all require a functioning septic evaluation before closing, and an unrenewed contract can become a timeline problem discovered at the worst possible moment.
None of this is unique to Anaqua Springs Ranch. It is unique to how many of its homesites are actually served, which is exactly why it deserves a direct question rather than an assumption.
If Your Lot Shows SAWS Water and Sewer
Ask for the utility account history and confirm there is no shared line agreement with a neighboring lot. Municipal service removes the septic maintenance question entirely, which simplifies both your due diligence and your ongoing cost of ownership.
If Your Lot Shows a Private Well and Aerobic Septic
Ask for the current maintenance contract and the last three inspection reports filed with the county. Ask whether the well has a recent water quality and quantity test on file. Build both into your option period rather than treating them as post-closing chores, since a lender-required evaluation can surface late if it has not already been done.
The Builder You Don't Get to Choose Alone
If the address in question is a vacant homesite rather than a finished home, a second layer of process applies before the utility question even matters. According to Anaqua Springs, every custom builder, house plan, and landscape plan goes through the community's architectural review committee before construction begins, and the community's own materials note that landscape plans go through the same review as the house itself, not a lighter-touch afterthought.
That review protects the visual consistency the community is built around. It also means a construction timeline here includes a step a typical suburban lot purchase does not: getting a builder and a plan approved. Anyone building from the ground up should request the architectural guidelines and the committee's approval process early in a lot purchase, not after a builder contract is already signed.
What the HOA Actually Charges, and When You'll See the Paperwork
Annual HOA dues in Anaqua Springs Ranch run around $2,695 as of 2026, with the association managed by FirstService Residential. On the closing side, a resale disclosure package and a buyer transfer fee apply; Texas law caps resale certificate fees at $375 under Property Code Section 209.0041.
Timing matters here too. State law requires an HOA to deliver a resale certificate after a written request and limits how far in advance the certificate can be prepared. A management company is not a party to your purchase contract, so it is not bound by the delivery dates your agent negotiates. Texas National Title explains that if the certificate arrives late, the buyer typically has the right to cancel under the standard HOA addendum. That is a reason to have your agent request the certificate the moment a contract is signed rather than waiting.
Before any of that, the association's own management certificate, the basic filing that confirms who manages the HOA and how to reach them, is a public record searchable through the state's HOA management certificate database, and Anaqua Springs Ranch Homeowners Association has one on file there.
Before You Write the Offer
A short list, worth having answered in writing before you move past option period:
- What is the exact water source for this lot: a SAWS meter or a private well?
- What is the exact wastewater system: SAWS sewer connection, or septic, and if septic, conventional or aerobic?
- If aerobic, is the maintenance contract current, and can the seller produce the most recent inspection reports filed with Bexar County's environmental services office?
- If this is a vacant lot, has a builder and plan already cleared architectural review, or does that step remain ahead of you?
- Has the HOA resale certificate been ordered yet, and by whom?
A Few Direct Questions
Does having a well affect financing? It can. FHA, VA, and USDA loans generally require a functioning septic evaluation before closing, and a lender may ask for well water quality documentation as part of underwriting. Confirm this with your loan officer early rather than during option period.
If a previous owner let the aerobic contract lapse, who is responsible now? The current owner, regardless of when the lapse happened. That responsibility transfers with the property, which is why documentation of an active contract at closing matters more than a verbal assurance that everything is fine.
Does architectural review apply only to the first build, or to later additions too? The community's own materials specify that landscape plans, not just house plans, go through the committee, which suggests a broad scope. If a pool, guest quarters, or major landscaping is part of your plan after closing, confirm the approval process directly with the HOA rather than assuming it only governs the initial build.
A gate, a security guard, and 920 acres of preserved Hill Country terrain tell you a great deal about what living in Anaqua Springs Ranch feels like. They tell you almost nothing about what runs under a specific lot. That is a question worth answering before an offer, not after an inspection report raises it for you.
