Septic System Do’s & Don’ts

Septic System Do’s

1. Inspect your septic tank annually - Septic Tanks should be pumped every three to five years. An inspection by you or Lilly’s Technician may show that you need to pump more or less often. Regular pumping ensures that solids will not flow from the septic tank into the drainfield. Solids  destroy the drainfield, and once a drainfield has failed, pumping will not bring it back to life.

2. Use less water - Reducing the amount of wastewater entering your Septic System may increase its life span, as excessive water is a major cause of system failure. Too much water from laundry, dishwasher, toilets, baths, and showers may not allow enough time for sludge and scum to separate, causing solids to pass out of the tank and into the drainfield, ultimately clogging the pipes. To reduce household water use:

• Limit the use of large water guzzling appliances, such as dishwashers and washing machines.
• Use water-saving bathroom and kitchen fixtures (such as faucets, showerheads, and toilets).
• Spread laundry over the entire week and avoid all loads on one day.
• Fix all faucet and toilet leaks promptly.

3. Direct water from downspouts and roofs away from the drainfield - Additional water from these sources may prevent your drainfield from working properly.

4. Keep cars and trucks off the septic tank and drainfield areas -  This prevents pipes from breaking and soil from becoming compacted. Compacted soils can’t absorb water from the drainfield.

5. Use phosphate-free detergent - Phosphorus is harmful to the environment, as it can deplete oxygen which is vital to fish and other aquatic organisms. The use of phosphate-free detergents, also helps prevent algae problems in nearby lakes and streams.

6. Use non clay based Liquid Laundry/Dishwasher Detergent - Liquid Detergents do not crystalize like powders do and create blockages in the baffles.  Clay based detergents tend to create excess sludge in a Septic Tank.

7. Install risers for easier access. Risers from the tank lids to the soil surface to make maintenance easier and avoid digging charges when you pump your Septic Tank.

Septic System Don’ts

1. Limit garbage disposal use - A garbage disposal adds solids and grease to your system, which could lead to drainfield failure.

2. Don’t use septic tank additives or “miracle” system cleaners - Some of these chemicals can actually harm your on-site sewage system by allowing solids to flow into and clog the drainfield. Some of these additives claim you never have to pump your Tank if you use them.  The reality is that you may not have to pump your Tank regularly but you’ll have to replace you Drainfield instead.  The chemicals can also contaminate ground and surface water. 

3. Don’t dispose of water from hot tubs into the on-site sewage system - Large volumes of water are harmful to the system, and the chlorine can destroy important bacteria in the system. Drain hot tubs onto the ground, away from the drainfield and not into a storm drain.

4. Don’t flush solid wastes into the septic system - These include diapers, cigarette butts, coffee grounds, tampons, condoms and grease.

5. Don’t put strong chemicals, such as cleaning products, down the drain - Household chemicals, such as drain cleaners, paint thinners and floor cleaners, can destroy important bacteria in your septic tank and contaminate ground and surface water.

6. Don’t construct patios, carports or use landscaping plastic over the drainfield - Grass is the best cover for your septic tank and drainfield. Soil compaction and paving prevents oxygen from getting into the soil. This oxygen is needed by bacteria to break down and treat sewage.

Home Owners Guide to How Septic Systems work

Households that are not served by public sewers usually depend on septic systems to treat and dispose of wastewater.  Septic Systems represent a significant financial investment. If cared for properly, a well designed, installed, and maintained system will provide years of reliable, low-cost service.

A failing system can become a source of pollution and public health concern, causing property damage, ground and surface water pollution (such as well water—both yours and your neighbors), and disease outbreaks. Once your septic system fails to operate effectively, you may need to replace it, costing you thousands of dollars. Plus, if you sell your home, your septic system must be in good working order. Therefore, it makes good sense to understand and care for your septic system.

There are many different types of septic systems that fit a wide range of soil and site conditions. The following will help you understand the main components of a standard (gravity fed) septic system and how to keep it operating safely at the lowest possible cost.

A standard septic tank system has three main parts:

• The Septic Tank — A septic tank’s purpose is to separate solids from the wastewater, store and partially decompose as much solid material as possible, while allowing the liquid (or effluent) to go to the drainfield. …
• The Drainfield — After solids settle in the septic tank, the liquid wastewater (or effluent) is discharged to the drainfield, also known as an absorption or leach field. …
• The Soil — The soil below the drainfield provides the final treatment and disposal of the septic tank effluent. After the wastewater has passed into the soil, organisms in the soil treat the effluent before it percolates downward and outward, eventually entering ground or surface water. The type of soil also impacts the effectiveness of the drainfield; for instance, clay soils may be too tight to allow much wastewater to pass through and gravelly soil may be too coarse to provide much treatment.
