Is the liquid coming from the septic tank “safe”?

No. Any way you look at it, septic tank effluent is sewage with some solids removed. It is still capable of spreading disease, breeding mosquitoes, causing odors and a nuisance.

Will it harm the septic tank to use disinfectants and bleaches for laundry and dishwashing?

No. The amounts of such products normally used should not harm the septic tank operation.

Should I use a starter, cleaner or other treatment aids in my septic tank?

No. It is not necessary to add yeast, raw meat, enzymes or other chemicals to start bacterial action in the tank. While starters or treatment aids are offered for sale, none are approved by this agency.

How often should I have the septic tank pumped?

It should be opened and inspected every three years or so, to see whether pumping is necessary. Most tanks will require pumping between three to five years. By periodic pumping of your tank, you will reduce the amount of solids and grease entering the drain field and extend its' life and the need for expensive repairs.

Should kitchen sink and laundry waste go into a separate tank?

No. All waste water from the home should be plumbed into a single large septic tank.

How can I reduce the amount of wastewater which goes into the drain field?

Considering the waste coming from your plumbing is over 95% water, it is wise to reduce that portion of the waste flow by:

• Repairing leaky fixtures (faucets, toilets, etc.)
• Washing clothes/dishes only when you have a full load.
• Taking short showers instead of baths.
• Using water saving devices in your toilet tank or installing new lowflow toilets.
• Installing lowflow shower heads.
• Not using the toilet as a waste basket; ie, for spider disposal, etc.

How can I tell when my drain field is malfunctioning?

• When there are odors, persistent wet spots and/or lush growth of grass in the area of your field.
• Your plumbing drain become sluggish when used heavily or during wet weather.
• Problems continue even though the septic tank has been recently pumped out.
