Troubleshooting

Problems sometimes occur. Lagoon depth may fall below 2-foot minimum due to leak in artificial liner, clogged inlet pipe, low flow rate into lagoon, holes in dike from plant roots or burrowing animals, not enough clay in natural soil liner or not compacted.

Irrigation Management Publications from Nebraska Extension

Harvesting Crop Residues, NebGuide G1846 Issues of crop residue harvest, including nutrient removal and effects on erosion, soil quality, water loss, and yield are discussed in this NebGuide.

Nutrient Management

Water quality is affected by nutrient management when chemicals, soil, and residue move off of agricultural land or below it. This section focuses on a number of production issues that when managed correctly minimize the potential for off-site consequences because excess of the nutrients is limited or eliminated.

Soil Erosion and Sediment Control

Soil erosion and sediment loss from construction sites has been documented as a major source of water pollution. Bare soil exposed to a rain event can become quickly eroded, leading to sediment that moves into adjacent storm sewers or lakes and streams. 

What happens in the lagoon?

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.

Soil Water

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.

Manure Related Extension Publications

The following are publications about manure and nutrient management.

Green Roofs

Green roofs help manage stormwater by capturing rainfall.

Pig Production Environmental Sustainability Footprints

A Nebraska Extension pilot project is assisting pork producers in calculating their swine farm environmental sustainability footprints in a joint effort with the University of Minnesota Extension.

Aquifers of Nebraska

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.

Septic systems operation and maintenance overview

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.

NebGuides

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

EPCRA Emissions Rule for Livestock and Poultry

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).

Low Impact Development

The key premise of low impact development (LID) is to allow natural systems to manage stormwater when and wherever possible.  LID takes advantage of existing natural features and also designs and constructs systems to imitate natural processes, for example, green roofs, bioretention gardens, and permeable pavement. 

What Happens in the Tank?

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.

Drinking Water Testing

Testing private drinking water supplies in Nebraska is not required by federal or state regulation, with some exceptions such as licensed childcare facilities and foster care home water supplies. County or city jurisdictions may have requirements for private water supply testing.

Controlling Emissions

Good stewardship calls upon livestock and poultry producers to limit emissions of air pollutants where feasible. Odor control practices and technologies may take several forms. Information on control strategies may focus upon the type of emissions controlled or the source of air emissions.

Common Pollutant Types

Sediment (sand, silt, and clay particles): Bare spots in lawns and gardens, lawn and landscape renovation projects, sloping areas, soil washed from vehicles, roof tops and other hard surfaces like driveways, pond or stream bank erosion, home construction.

Wastewater - What Is It?

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

How does a septic system work?

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