Deephaven Inflow & Infiltration

A letter about street reconstruction can bring an unexpected item to your to-do list: proving your sewer line isn’t leaking clear water into the city system. Our team knows how Deephaven’s rules work and can get your line inspected before the project timeline gets tight. Call 763-314-3148 to get on the schedule.

Deephaven I&I Program

Deephaven takes a different approach than many of its Lake Minnetonka neighbors. Instead of requiring an inspection when a home sells, the city ties its requirement to road work. In October 2023, the City Council amended Ordinance Chapter 1005.04, Subdivision 5. The amendment clarified that the property owner owns the sewer lateral and required owners to inspect and repair it when a road project is approved for the street that abuts their property.

The city’s 2025 engineering request for proposals describes how this plays out. Private laterals next to roadway projects get inspected, and any that show inflow and infiltration must be repaired or replaced within a set window tied to the construction project. That same document notes that Deephaven has 1,485 sewer connections, all sending wastewater to the Metropolitan Council for treatment. Every gallon of clear water in those pipes is a gallon the community pays to treat.

Here’s what Deephaven property owners should keep in mind:

• The trigger is a road project. When the city approves reconstruction on your street, your lateral needs an inspection.
• The lateral belongs to you. Repairs to the private line are the owner’s responsibility, not the city’s.
• Repairs run on a deadline. The repair window follows the road construction schedule, so waiting can leave little room to plan.
• Point-of-sale rules were discussed but not adopted at that meeting. The City Council held a workshop on a point-of-sale inspection option on August 18, 2025, and the packet notes no formal action was taken. Confirm current rules with city hall before you list.

Deephaven’s authority comes from Minnesota Statutes section 471.342, which allows cities to create I&I prevention programs and offer loans or grants to property owners. The Minnesota Pollution Control Agency points out that state law doesn’t require a lateral inspection during a real estate sale, so each city sets its own triggers.

Clear Water Sewer Connection Deephaven

Many Deephaven homes started as lake cottages around Cottagewood, Carson’s Bay, and St. Louis Bay, then grew through decades of additions and remodels. Somewhere along the way, a lot of them picked up connections that send clean water into the sanitary line. The city’s records also show that most Deephaven properties draw water from private wells, yet those homes still discharge wastewater into the public sewer, so the lateral matters just as much.

The I&I needs we see most often in Deephaven include:

• A recorded lateral inspection after the city announces street work
• Rerouting sump pumps that empty into a floor drain or laundry tub
• Disconnecting old foundation drains tied into the sanitary sewer
• Separating roof downspouts that run underground toward the house
• Pre-purchase camera inspections for buyers who want answers before closing

Sump Pump Disconnection Deephaven

Lakeside lots often carry a high water table, which keeps sump pumps busy through spring. If the discharge hose drops into a basement drain, all of that groundwater travels straight to the treatment plant. We redirect the discharge outdoors or to an approved storm connection, then confirm nothing else on the property is feeding the sanitary line.

Basement Sewer Backup Deephaven MN

Snowmelt and heavy summer storms push extra water into every weak point underground. When clear water fills the sewer system, sewage has fewer places to go, and a lower-level floor drain can become the overflow point. A backup is often the first sign homeowners notice, though the cause usually started years earlier.

Problems that commonly let clear water into Deephaven laterals:

1. Roots from mature oaks and maples working into pipe joints
2. Older clay or cast iron sections with separated joints
3. Sags in the line where soil has settled near slopes and shorelines
4. Cracks that let groundwater seep in during wet seasons
5. Forgotten drain tile connections hidden behind finished walls

Gurgling toilets, slow drains on the lowest level, and sewer odor after rain all point toward the lateral. Each one deserves a closer look before a road project notice forces the timing.

Sewer Camera Inspection Deephaven MN

Our Empowerment Guarantee means you see the same video we see. No guessing about what’s happening under the lawn. A typical visit follows this order:

1. We locate the main cleanout and make sure it’s accessible.
2. If roots block the camera, the line gets cleaned first so the inspection can be completed.
3. The camera travels from your home to the connection at the city main, recording the entire run.
4. We check sump pump discharge, floor drains, and any suspicious connections.
5. You get a plain-language walkthrough of the footage, along with upfront pricing for any repair.
6. Recorded video and documentation are prepared so you can provide them to the city.

Sewer Line Inspection Deephaven

Timing makes a real difference here. The city’s street improvement project map shows which areas have work planned, and Metropolitan Council restoration around lift station L48 has touched Cottagewood Road, Ridgewood Road, and Vine Hill Road. If your street appears on a schedule, inspecting early gives you more repair options and more breathing room on cost.

Sewer Lateral Repair Deephaven MN

A failed inspection rarely means the whole yard has to come up. The video tells us exactly where the defects are, and the repair can be sized to match. Options we use in Deephaven include:

• Spot repairs for damage limited to one section of pipe
• Full-length trenchless lining that seals every joint and crack
• Disconnecting and rerouting improper clear water connections
• Targeted excavation only when the line has collapsed or can’t be lined

Sewer Pipe Lining Deephaven

Founder Ben Smith built Marvel Sewer & Drain around no-dig repair back in 2010, and lining remains one of the best fits for Deephaven properties. A resin-saturated liner is placed inside the existing lateral and cured into a new, sealed pipe wall. Landscaped lake lots, retaining walls, and established trees stay where they are. The old pipe stays underground, too, serving as the host for a stronger line inside it.

Frequently Asked Questions

Does Deephaven Require A Sewer Inspection Before Selling A Home?

Deephaven’s ordinance ties lateral inspections to approved road projects rather than home sales. The City Council discussed a point-of-sale option at an August 2025 workshop without taking formal action, so check with city hall for current rules before listing.

What Triggers A Sewer Lateral Inspection In Deephaven?

An approved road project on the street next to your property. Once the city approves the project, owners must inspect the lateral and repair any defects within the window tied to construction.

Who Owns The Sewer Lateral In Deephaven?

The property owner. Deephaven’s 2023 ordinance amendment clarified that the lateral belongs to the owner, which makes inspection and repair costs the owner’s responsibility.

How Can I Tell If My Sump Pump Drains Into The Sanitary Sewer?

Follow the discharge hose from the pump. If it ends at a floor drain, laundry tub, or utility sink, it’s likely sending clear water into the sanitary line and should be rerouted outdoors.

Can My Sewer Lateral Be Repaired Without Digging Up My Yard?

In many cases, yes. Trenchless lining and spot repairs fix cracks and separated joints from inside the pipe, protecting lawns, gardens, and hardscaping.

Should Buyers Get A Sewer Camera Inspection In Deephaven?

It’s a smart step. Without a point-of-sale requirement, a camera inspection is the only way for a buyer to see the lateral’s condition before closing.
