Consult with Shoreline Zoning laws before cutting. Trees take years to grow and only minutes to cut down. Do check sludge leave in septic tank every two years. If settled solids are not removed from tanks, they will wash into and clog the leach field. Septic tanks are living systems.
Strong cleaners kill the microorganisms that break down the waste.
Don't install or use an in-sink garbage disposal. Ground garbage over burdens your septic tank and slows its functions. Don't use commercial products that claim to clean your septic tank without pumping. These products can cause clogging of your leach field, and may contain chemicals which cab contaminate drinking and lake water. Don't put paint or chemicals into the septic system.
