Wastewater

The holiday season is upon us and that often means a bustling house full of family, friends, and preparation of tasty recipes in the kitchen. All of these things should make for joyful times, but they can potentially have a stressful impact on your private water well and onsite wastewater systems.

The new year is a time where we all make goals and a plan of attack for the upcoming 12 months.  We often think of things we will do to improve our health, save money or be more organized in all or part of our daily lives. One way to take steps to be more organized and also protect your and others’ health as well as the environment is to get reacquainted with your water system--both your drinking well and your on-site wastewater system—and to establish a testing and maintenance schedule for the upcoming months. 

This year’s National SepticSmart Week is September 18-22, 2017. The Environmental Protection Agency (EPA) uses a week in September each year to focus on improved awareness of proper operation and maintenance of septic systems across the United States. The wastewater of approximately 25 percent of the population of the United States is treated by on-site or individual wastewater systems. In Nebraska, this statistic holds consistent with 25 percent of our state’s population being served by onsite wastewater systems on farms, acreages, suburbs and even some small communities.

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.

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.

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.

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.
