Water Conservation Tips

Reducing water usage extends time between pumping and protects your drainfield.

Fix Leaky Faucets

Up to 200 gal/day

A single dripping faucet can waste 20 gallons per day

High-Efficiency Toilets

1.6 vs 3.5 gal/flush

Old toilets use over twice as much water per flush

Spread Laundry Loads

Reduces peak load

Avoid doing all laundry on one day to prevent overloading system

Shorter Showers

2.5 gal/minute saved

10-minute shower uses 25 gallons; 5-minute uses 12.5 gallons

Never Flush These Items

Wet wipes (even "flushable")

Don't break down, clog pipes

Feminine hygiene products

Non-biodegradable, cause clogs

Condoms

Non-biodegradable

Dental floss

Wraps around components

Cotton swabs/balls

Don't break down

Diapers

Expand and cause serious blockages

Cat litter

Even "flushable" types damage systems

Cigarette butts

Filters don't biodegrade

Medications

Kill beneficial bacteria, contaminate groundwater

Paper towels

Too thick to break down quickly

Chemicals to Avoid

Bleach (excessive)

Kills beneficial bacteria

Drain cleaners

Caustic chemicals damage tank and bacteria

Paint/solvents

Toxic, contaminate groundwater

Antifreeze

Toxic to bacteria and environment

Pesticides

Kill bacteria, contaminate groundwater

Gasoline/oil

Highly toxic, fire hazard

Antibacterial soaps (excessive)

May reduce beneficial bacteria

Protecting Your Drainfield

Your drainfield is the most expensive component to replace. Protect it with these practices:

✓Keep vehicles off: Weight compacts soil and damages pipes

✓Divert surface water: Route gutters and drainage away

✓Plant only grass: Deep roots from trees/shrubs damage pipes

✓Keep area accessible: For inspections and repairs

✗No construction: Don't build patios, sheds, or pools over it

✗No irrigation: Don't water lawn directly over drainfield

✗No heavy equipment: Tractors, trucks can crush pipes

✗No plastic covering: Soil needs oxygen for treatment

Keep Maintenance Records

Maintain a file with your septic system information:

• System installation date and permit

• Site map showing tank and drainfield location

• Pumping records with sludge/scum levels

• Inspection reports and repairs

These records are valuable when selling your home and help track system health over time.
