Review of Plans and Specifications

Engineering plans and specifications for proposed construction, installation, or modification of wastewater disposal systems, treatment works, sewerage systems or common sewers must be submitted to DEQ for review and approval prior to construction, except where exempted. This is required by Oregon Revised Statute 468B.055. OAR 340-052-0015 details plan submittal requirements. OAR 340-052 Appendix A and Appendix B contain requirements for gravity sewerage systems and sewerage pumping stations, respectively.

Submitting wastewater reports and plans for approval

Please send the following to the DEQ engineer who is assigned to the area of your project (see the list of engineers below)
  • Plans, specifications and reports. Note: electronic versions are acceptable. 
  • Land Use Compatibility Statement, or LUCS, signed by the local land use authority. Note: A LUCS which is part of a submittal for approval of plans and specifications should check the box for "Wastewater/Sewer Construction Plan/Specifications" in subsection 1D, and check "Other" in subsection 1E. Electronic versions are acceptable.  
  • Payment of DEQ Technical Activities Fee in OAR 340-045 Table 70 F. DEQ can invoice the system owner if that is the owner’s preference.

​​​​​DEQ wastewater engineers use the following guidelines to evaluate plans. DEQ advises that the appropriate DEQ wastewater engineer be consulted prior to plan submittal if a deviation is desired to avoid additional redesign expenses. Note: this updated (3/1/2021) list contains a revised guideline for pump station design standards; this newer guide incorporates four previous guidelines which are no longer listed below (“Design Notes for Air Injection Stations and Sewage Force Mains”, “Guidelines for Hydrogen Sulfide Tests”, “Guidelines for Writing Pump Station Operations and Maintenance Manuals”, and “Operations and Maintenance Notes for Gauges on Sewer Pumps”).

  1. Alternative Guidelines for Estimating Leakage from Smaller (less than 2 acres) Existing Sewage Lagoons

  2. Design Notes for Non-Discharging Sewage Lagoons

  3. Guidelines for Design of Septic Tank Effluent Pump or Gravity (STEP/STEG) Sewer Projects involving Common Sewers

  4. Guidelines for Estimating Leakage from Existing Sewage Lagoons

  5. Guidelines for Making Sewage Pump Station Plan-Review Submittals

  6. Guidelines for Making Wet-Weather and Peak Flow Projections for Sewage Treatment in Western Oregon

  7. Guidelines for Writing Wastewater Engineering Design and Pre-Design Reports

  8. Preparation of Operations and Maintenance Manuals for Domestic Wastewater Treatment Facilities
