Where we work

Oklahoma Water And Wastewater Engineering

Water and wastewater engineering in Oklahoma for towns, rural water districts and developers. ODEQ permits, OWRB water rights, design and construction.

What we do in Oklahoma

Water and wastewater engineering in Oklahoma

Modern Engineering Solutions (MES) provides water and wastewater engineering in Oklahoma for towns, rural water districts, utilities and developers. We also do site civil engineering for land development, and construction administration once plans are approved.

MES is licensed in Oklahoma. A project can run from a condition report and funding support through plans, specifications, bidding and closeout.

How water and wastewater permitting works in Oklahoma

The Oklahoma Department of Environmental Quality (ODEQ) issues construction permits for public water and wastewater systems. That covers water lines, wells, pump stations, storage tanks and treatment plants. It also covers sewer lines, lift stations, force mains and wastewater treatment.

Wastewater permits take two steps. An engineering report goes in first. The final design, with plans and specifications, follows. A permit expires if construction does not start within one year, unless ODEQ grants an extension.

ODEQ also covers construction stormwater. A site that disturbs one acre or more, or is part of a larger common plan over one acre, needs coverage under the OKR10 general permit and a stormwater pollution prevention plan before work starts.

The Oklahoma Water Resources Board (OWRB) handles water rights. Using stream water or groundwater for anything other than domestic use takes an OWRB permit. OWRB also coordinates the National Flood Insurance Program in Oklahoma and accredits the local floodplain administrators who issue floodplain development permits.

Cities and counties review plats, grading, drainage and local utility standards. Utility work in a state highway right of way needs a permit from the Oklahoma Department of Transportation (ODOT).

Work in Oklahoma

In Sasakwa, a small town in Seminole County, the coating on the town's water storage tank had broken down and the structure showed wear. MES assessed the tank and wrote the engineering report that supported the town's grant application. We then prepared the recoating and repair plans and specifications, supported bidding and provided construction phase services through closeout in April 2026. See the Sasakwa water tank project.

Common questions

Does a new water or sewer line in Oklahoma need an ODEQ permit?

In most cases, yes. ODEQ allows limited exceptions for small extensions by some cities and rural water districts, within size and length limits. We confirm which path applies before design starts.

Who handles water rights in Oklahoma?

The Oklahoma Water Resources Board. A project that draws its own stream water or groundwater for anything other than domestic use needs an OWRB permit. A project served by a city or rural water district takes its water from that provider.

Can a small town get help paying for water or sewer work?

Yes, there are state programs. ODEQ and OWRB jointly run the Drinking Water State Revolving Fund, which makes low interest loans to towns, cities and rural water districts. OWRB's Clean Water State Revolving Fund lends for wastewater work. In Sasakwa, an MES engineering report supported the town's grant application.

  1. An engineer reads it

    Not a salesperson. Someone who can tell you whether the pathway is real.

  2. You get a first answer

    Your options, the agencies involved and the questions that decide cost and schedule.

  3. You decide

    No commitment to have the first call.
