Incomplete Registrations

You may have received a notice in the mail from NDEE about an incomplete registration you submitted recently. We have summarized the most common registration problems below.

New Forms – New forms were mailed to all certified professionals in September 2012. The old form G’s are no longer accepted. If you need copies of the forms they can be found on our website – dee.ne.gov “Licenses & Certification” then “Onsite Wastewater Program (septic systems, private lagoons)” and then “Registrations and Registration Requirements” and print the correct form(s). We will mail copies if requested.

Example: See attached PDF

Inside bottom width of chambers - The effective width of the trench for a system using gravelless chambers (with at least six inches of slotted sidewall, specifically designed for use without filter material) may be up to 1.5 times the bottom width of the chamber, measured as the distance between the inside edges of the base flanges of the chamber. The effective width calculation does not apply when filter material is used in the trench (Filter material is 1/4 inch or larger gravel, rock, etc.).

Total effective trench bottom area – Using example diagram above - Inside bottom = 32 inches. Effective width = 32 X 1.5 = 48 inches (or 4 foot). (For 300 ft. total trench length) 300 ft. X 4 ft. = 1200 sq. ft. total effective trench bottom area. If filter material (gravel, rock, etc.) is used then you cannot use the effective width credit. With filter material, use the width of the gravel-filled trench, or for this example 300 ft. X 3 ft. = 900 sq. ft. of total effective trench bottom area.

Total trench length – Example: Three 100 foot trenches equal a total trench length of 300 ft.

Modification – If any part of a septic system is modified, all of the system must meet the current standards. If a septic tank is replaced, Title 124 requires that the drainfield also meet current standards. The number of trenches and trench length, along with depth to groundwater are required on septic system registrations.

New Programs for Professional Development Hours (PDH)

Approved programs are also listed on the NDEE’s website (dee.ne.gov then select “Licenses & Certification” then “Onsite Wastewater Program (septic systems, private lagoons)” and then “Continuing Education”). Each day has been approved for 6 PDH.
