Maintaining Your Septic System

What makes a good septic system? A properly designed, constructed, functioning and maintained septic system protects human and environmental health. This includes, but is not limited to surface water, groundwater and soil quality in the immediate vicinity of the proposed onsite wastewater system site. A good habit to adopt is an annual inspection of and maintenance of your onsite wastewater system to help ensure a well-balanced, working septic system. Wastewater 101

Inspect and maintain your wastewater lagoon now

The arrival of spring, warm weather and sunshine brings a flurry of activity around your acreage. Annual plantings are done, mulch is purchased, spring cleaning is completed and the mowing season begins.  All of those things are done annually to maintain homes and yards.

Yeast Additives and Wastewater Lagoons

Additives such as yeast are marketed as a quick and easy way to improve bacterial degradation of the wastewater within a system such as a lagoon.  However, the reality is that none of the yeast additives have been proven to be effective in improving bacterial action within your lagoon.  Additionally, yeast additives have shown to have negative impacts on groundwater quality as well as potential further negative impact on surrounding environmental resources such as vegetation.  If you think the waste treatment is insufficient, consider taking the following two steps:

Operation & Maintenance

Now that you know how a lagoon works, here is what you need to do to operate and maintain your system for maximum efficiency and long life. Minimize your exposure to wastewater - it contains disease-causing bacteria and viruses. Wear waterproof gloves, wash hands or shower, and disinfect breaks in skin after exposure to wastewater.

How Does a Lagoon Work?

A traditional lagoon system is a two part system. A traditional system has plumbing from the house and a lagoon.

Design & Size Requirements

Lagoon size is determined by the number of bedrooms, as well as the annual evaporation and precipitation rates for the geographic region. The lagoon size is NOT based on the square footage of the house, or the number of people living in the house because occupancy can change.

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.

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.
