Evaporation reduces the liquid volume of wastewater, returning water vapor to the environment. Solids settle to bottom and form sludge. There is an aerobic zone at the top of the wastewater layer where air movement introduces oxygen and aerobic microorganisms convert waste to carbon dioxide, ammonia, and phosphates.

Irrigation scheduling needs to begin with a discussion on soil and soil water. This is the basis of irrigation scheduling. Coarse soils, such as sands and gravels, have relatively large pores. However the number of pores is small when compared to a finer textured soil. Fine soils, like clays or clay loams, have relatively small pores. Having many small pores means that a fine textured soil can hold more water than a coarse textured soil.

On December 18, 2008, the US EPA published a final rule that clarified which livestock facilities must report air emissions from their facilities. Animal agriculture was granted an administrative exemption from reporting air emissions that normally occur from raising farm animals under the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA).

There are at least seven major aquifer systems in Nebraska. By far, the High Plains/Ogallala aquifer is the largest in terms of volume of water in storage and withdrawals for irrigation. Several secondary aquifers exist in areas outside of the High Plains aquifer, providing water for irrigation, municipal supplies, and domestic use in parts of far western and far eastern Nebraska.

Pump tank regularly. Have a professional inspect and pump the tank. Conserve water and spread usage over a period of time. Manage solids. Keep hazardous materials out. Let the system work naturally. Avoid drainfield compaction. Avoid introducing excess water to the drainfield. Maintain structural integrity of the drainfield.

A collection of NebGuides developed by Nebraska Extension professionals on various drinking water topics.

Step-by-step instructions for using the worksheet version of the Odor Footprint Tool and an example completed worksheet are provided in the following documents.

Anaerobic bacteria begin to break down some wastes in the tank. Wastewater contains suspended solids. Heavy solids settle out and form sludge on the bottom of the tank.

The NPDES permittee, authorized representative, or an employee of the operation shall complete a land application training program approved by the Department within 180 days of NPDES permit coverage unless such training was satisfactorily completed in the previous 5 years. Additional training is required every 5 years.

Aim downspouts towards planted areas or pervious hardscape and away from impervious paved areas. Collect rainwater from rooftops in rain barrels or cisterns for reuse in landscape irrigation. Amend soil with organic matter. Core aerate lawns to help avoid or reduce soil compaction, increase water infiltration, and promote healthy root systems. Follow University and label recommendations and calibrate spreaders when using fertilizers and pesticides.  Only use these products when needed. Read and follow label directions for all lawn chemicals.

Wastewater comes from ordinary living processes: bathing, toilet flushing, laundry, dishwashing, etc. It comes from residential and domestic sources.

A system typically has 3 parts: plumbing from the house, a septic tank, and an effluent treatment system.

The NDEQ Web site provides numerous publications to assist producers with Title 130 compliance including annual report forms, applications and forms, fact sheets, guidance documents, and standard operating procedures.
