Repairs, from cheap to shouldn’t-have-waited
The recurring cast: baffles ($250–$600 — replace on sight, they’re the drainfield’s bodyguard), cracked lids (a safety fix, not a someday fix), stuck floats, and on aerobic units the compressor and sprayer pump ($450–$1,200). What turns small into large is time: a torn baffle passes solids into the field for a year before the field complains, and the field is the one part nobody can repair with a wrench. If a pump-out or maintenance visit flags something — fix it that month, not that fiscal year.
When it’s the drainfield
Persistent soggy ground, effluent surfacing, backups that return right after pumping — that’s field talk. Options run from remediation and rest-rotation (sometimes) to replacement (often, on fields that were undersized or abused for decades). Replacement in this county means a permit and a fresh site evaluation, and honestly weighing whether the same design belongs in the same dirt — or whether the answer is stepping up to aerobic. Nobody can price that over the phone; walk-the-site bids only.
New systems for a county that’s building
Here’s the Bastrop County wrinkle that surprises people from elsewhere: there is no acreage exemption. Ten acres, a hundred acres — every new system is permitted through Development Services ((512) 581-7176) with a licensed site evaluation. The evaluation reads your soil and picks your lane: the sandier ground common north and east of Elgin often supports a conventional system at $4,500–$9,000 installed and permitted; tighter soils and small lots push to aerobic at $10,000–$20,000 plus the ongoing 3-inspections-a-year contract. Budget it into the build from day one — it’s a real line item, and lenders on construction loans will ask.
Reading an install bid
A complete bid names the system type and gallonage, includes the site evaluation and county permit, states who runs the electrical circuit (aerobic systems need one), covers final grade and cleanup, and puts warranty terms in writing for tank and components. Bids that are thousands cheaper are usually just missing paragraphs — and every missing paragraph reappears later as a change order.
Common questions
What does a new septic system cost near Elgin?
Where soils allow a conventional system: $4,500–$9,000 installed and permitted. Where the site evaluation calls for aerobic: $10,000–$20,000 plus the annual maintenance contract. The evaluation — not the salesman — decides which you need.
Is it true every install needs a permit here?
Yes. Bastrop County opted out of the state’s large-tract exemption — every install, replacement or major alteration is permitted through Development Services with a site evaluation, regardless of acreage. Installers who work this county handle it as routine.
Can my failing field be "rejuvenated" like the ads say?
Sometimes remediation buys real time; sometimes it’s a $2,000 delay on a replacement. The honest answer requires knowing why the field failed — age, abuse, sizing, or water table. Get that assessment from someone who also installs, so they profit either way and can afford to tell you the truth.
How long from "yes" to working system?
Site evaluation and county permitting typically run a few weeks, then 2–4 days of installation plus inspections. Boom-county backlogs are real — if your build has a septic dependency, get in the queue early.
