Water and Wastewater Treatment Design

Engineering for municipal and industrial water and wastewater treatment plants, package plants, upgrades and permits.

Typical US fee$50,000 to $1,000,000
Typical timeline6 months to several years
Licensing boardMinnesota Board of Architecture, Engineering, Land Surveying, Landscape Architecture, Geoscience and Interior Design (AELSLAGID)

What the work involves

Engineers plan and design treatment processes, pumping, tanks, buildings and controls for drinking water and wastewater plants, plus package plants for developments and industrial pretreatment. Work usually starts with a facility plan, then design, permitting, funding applications such as State Revolving Fund loans, and construction phase services.

Local conditions we plan for

  • Deep frost penetration and frost heave
  • Heavy snow loads
  • Riverine and spring snowmelt flooding (Red River)
  • Peat and soft organic soils

Building code: 2018 IBC/IRC adopted at the state level (ICC adoption chart, April 2026).

When you need it

  • Plant nearing capacity or aging out
  • New or tighter discharge permit limits
  • Development needs a package treatment plant
  • Industrial facility needs pretreatment
  • Utility applying for state revolving fund financing

Frequently asked questions

How much does water and Wastewater Treatment Design cost?

Across the US, water and Wastewater Treatment Design usually costs $50,000 to $1,000,000. Estimate. Fees scale with construction cost and commonly run to a substantial percentage of it on public projects; small package plants are at the low end.

How long does water and Wastewater Treatment Design take?

Plan on 6 months to several years from signed proposal to stamped deliverables, longer if a site visit, soil testing or a permit review cycle is involved.

Do I need a licensed PE for water and Wastewater Treatment Design?

In most US jurisdictions, yes. When the work needs a permit, the plans, calculations or report usually must be sealed by a Professional Engineer licensed in the state where the project is located. Every deliverable we issue for permit is sealed that way.

How do I verify an engineer's license in Minnesota?

Engineers practicing in Minnesota are licensed by the Minnesota Board of Architecture, Engineering, Land Surveying, Landscape Architecture, Geoscience and Interior Design (AELSLAGID). You can confirm a license number and its status in the board's public license search before you sign a contract.

How deep is the frost line in Minnesota?

Minnesota Rule 1303.1600 sets minimum footing depth for frost protection at 60 inches in Zone I (northern counties) and 42 inches in Zone II (southern and metro counties), unless an engineer competent. Local building departments set the required footing depth, so confirm the exact figure for your county before designing foundations or retaining walls.

Which building code applies in Minnesota?

2018 IBC/IRC adopted at the state level (ICC adoption chart, April 2026). Cities and counties can add local amendments, which is one reason to hire an engineer who works in your area.
