Septic services we match
Septic work is not one job. A new build on a vacant lot, a failing drainfield behind a 30-year-old house, and a seller staring at a compliance deadline are three different projects with different permits, timelines, and price drivers. We route your request by project type, so the installer who calls you is set up for the work you actually have.
Septic System Installation
New systems for new homes and lots, designed around your soils, water table, and bedroom count, then permitted and installed to Minnesota code.
Septic System Replacement
Full or partial replacement of failing and noncompliant systems, including mound conversions when soils no longer allow a conventional field.
Compliance Inspections
MPCA-certified compliance inspections for property sales, permits, and additions — with the paperwork your county and closer actually need.
Septic System Design
Site evaluations, soil borings, and permit-ready designs from certified designers, including primary and alternate drainfield sites.
Drain Field Repair
Some failing fields can be repaired or partially rebuilt instead of replaced. Ask through the quote form and an installer will judge your site honestly.
Septic Pumping & Maintenance
Routine pumping keeps a healthy system healthy. We are adding pumping matches now — send a request and we will route it if a provider is available.
Why septic decisions in Scott and Dakota Counties deserve care
A septic system is the largest piece of infrastructure most rural homeowners will ever buy — buried, regulated, and expensive to redo. South of the Minnesota River there is no city sewer to fall back on. When a system fails here, it does not just inconvenience a household — it can hold up a home sale, block a building permit, or put a family on a pumping schedule while they wait for a replacement.
The rules add a second layer. Minnesota licenses septic professionals through the MPCA, counties run their own ordinances and permit offices, and the two counties we serve treat property sales very differently. Dakota County requires a compliance inspection at transfer. Scott County ties inspections to permits, additions, lot splits, and changes of use. Getting the sequence wrong — designing before a site evaluation, or listing a home before the inspection — costs weeks.
How it works
- Tell us about your property. One short form: where the property is, what you need, and any deadline you are working against, such as a closing date or a permit application.
- We match you with one licensed local installer. Not a list of companies and not an auction. Your details go to a single MPCA-licensed installer who handles your type of project in your county.
- The installer visits and quotes in writing. You get an itemized, written quote based on your actual soils and site. Hire them, get another opinion, or walk away — the quote is yours either way.
What is actually underground
Most homeowners never see their system — it is buried the day it is installed and forgotten until something goes wrong. This cutaway shows what is actually underground: every drop of wastewater the house produces passes through the tank, where solids and grease separate out, and the liquid that leaves is finished by the soil itself.
What a septic system costs here
Prices swing widely because soil does the deciding. A straightforward conventional system on good soil is a very different project from a mound system on a tight, wet lot. These planning ranges for the Scott/Dakota County area are explained in full in our cost guide.
| System type | Typical installed range |
|---|---|
| Conventional trench or bed system | $10,000 – $25,000 |
| Mound system | $25,000 – $45,000 |
| Advanced treatment system | $30,000 – $50,000+ |
Bedroom count, tank size, pumping distance, lot access, and permits all move the number. Any quote given without a site visit is a guess; these ranges are for planning, not pricing.
Service areas
We concentrate on the exurban communities south of the river where septic is the norm and most homes will never see a city sewer line.
Elko New Market
A merged city with sewer in its core and septic across its outskirts and township acreage.
Credit River
A young city of large rural-residential lots where private wells and septic systems serve most homes, from the river valley to the bluffs.
New Prague
A two-county city whose in-town homes sit on municipal sewer, while fringe neighborhoods, townships, and lakeshore lots still rely on septic.
We also take requests from nearby communities and townships across Scott and Dakota Counties, including Lakeville-area acreage, Eureka and Castle Rock townships, Helena and Cedar Lake townships, and rural Prior Lake and Jordan addresses. If your property is on septic and in either county, send the form and we will tell you honestly whether we can match you.
Why get matched instead of calling around?
Calling around sounds free, but it costs the one thing sellers and builders never have: time. Septic installers in this area are small crews booked weeks out. Repeat that with three companies and you have spent a month collecting numbers that are not comparable anyway, because each installer scoped the job differently.
A matched request flips the work. Your project details, deadline, and property facts go in once, in a format an installer can actually bid from. The installer who receives it knows the county, knows the project type fits their crew, and knows you are expecting a written quote. You still own the decision — one written quote in hand is a starting point you can take anywhere, including to a second installer you find yourself.
There is also a quality filter built in. We only route requests to installers who hold the MPCA license their work requires and who work under Scott County Ordinance No. 4 or Dakota County Ordinance 113 as applicable. Licensing guarantees training, bonding, and a regulator who answers complaints.
Common questions
How much does a new septic system cost in Scott County?
Most conventional systems in the Scott and Dakota County area land between $10,000 and $25,000 installed, while mound and advanced-treatment systems commonly run $25,000 to $50,000 or more. Soil conditions, water table depth, home size, and access decide where a given property falls. The only number that matters is a written quote based on your soils, which is why we match you with an installer who evaluates the site before pricing. Our cost guide breaks down the ranges by system type.
Are you a septic contractor?
No. Scott County Septic is a matching service, not a contractor. We do not design, install, repair, pump, or inspect systems, and we never mark up the installer's price. We take your project details and pass them to one independent, MPCA-licensed installer serving Scott and Dakota Counties. That installer visits your property, prepares a written quote, and is solely responsible for the work, permits, and warranty.
What happens after I submit the form?
Your request goes to one licensed local installer whose work fits your project type and location. The installer contacts you directly to talk through the property and schedule a site visit if one is needed. You receive a written, itemized quote you can compare, keep, or decline. There is no fee from us and no obligation to hire anyone. If the project is not a fit, the installer will say so plainly rather than leave you guessing.
Do I need a compliance inspection to sell my home?
It depends on which county and city the property sits in. Dakota County's Ordinance 113 requires a compliance inspection for the sale or transfer of properties served by a septic system. Scott County's Ordinance No. 4 does not list a sale by itself as an inspection trigger, though permits, additions, lot splits, and changes of use can trigger one, and Minnesota law always requires a written septic disclosure. Our compliance guide explains both counties in plain language.
Which areas do you cover?
We focus on the septic-served exurbs of Scott and Dakota Counties: Elko New Market, Credit River, New Prague, and surrounding townships, plus Dakota County properties facing a compliance inspection at sale. Homes inside municipal sewer districts do not need septic work, and part of our job is telling you honestly when your address is on city sewer and this service is not for you.
