No, dumping grease down your house drains will cause grease buildup in your own drain lines. Some people believe that if you mix hot water with the grease, it will not clog your lines. While this may not clog the lines in your immediate house, by the time the grease gets to your sewer pipe it will have cooled enough to build up. Keep in mind, you are responsible for the maintenance of your side sewer and calling out a plumber for this type of maintenance can be very expensive.
No, oil causes the filtration system at the treatment plant to fail and the filtration system must be cleaned and replaced, causing thousands of dollars in damage.
No, flushing plastic items and other non-biodegradable material, such as many brands of baby-wipes, down the toilet causes problems in sewer lines. The material will hang up in your line and cause blockages. If the material reaches the treatment plant it will cause problems in the treatment process as well.
The manhole is used for access to the system for maintenance and cleaning.

Sewer lines are systematically cleaned using high-pressure jet nozzles that scour the sewer lines of grit and grease debris that is then vacuumed out and disposed of at the treatment plant. An inspection camera is also used to view the inside of the sewer lines for evaluation purposes to determine line repair or replacement.

Each year, a few Mukilteo Water and Wastewater District customers call to ask about a slimy pink substance that sometimes forms in moist areas around their homes. They most frequently observe it in toilet bowls, on the surfaces in shower stalls and bathtub enclosures, in sinks, and in pet water dishes.
A red or pink pigmented bacteria known as Serratia marcescens is thought to be the cause of pink stuff. Serratia bacteria are common inhabitants of our environment and can be found in many places, including human and animal feces, dust, soil, and in surface water. The bacteria will grow in any moist location where phosphorus containing materials or fatty substances accumulate. Sources of these substances include soap residues in bathing areas, feces in toilets, soap and food residues in sinks, and food residues in pet water dishes. Serratia can also grow in tap water in locations such as toilets in guest bathrooms where the water is left standing long enough for the chlorine residual disinfectant to dissipate. Serratia marsescens is not known to cause any waterborne diseases.
Once established, the organism usually cannot be eliminated entirely. However, periodic and thorough cleaning of the surfaces where the pink slime occurs, followed by disinfection with chlorine bleach appear to be the best way to control it. Scrub the surfaces where phosphorus and fatty substances, or the bacteria accumulate with a brush and a household cleanser. Then disinfect the surfaces where the slime has formed with a strong chlorine bleach solution. Leave the disinfectant solution on the affected surface(s) for 10 to 20 minutes before thoroughly rinsing it away with clean water.
To control pink “stuff” in toilets, clean the bowl thoroughly and spray chlorine bleach into the bowl and under the bowl rim. Also add ¼ cup of bleach to the toilet tank. Let the bleach stand for 15 to 20 minutes. After 15 to 20 minutes, flush the toilet a couple of times to rinse the disinfectant out of the tank and the bowl. Whenever a pink film starts to reappear, repeat the cleaning and disinfection process. Note: Bleach should not be left in the toilet tank for prolonged periods; it will damage the rubber valves and seals inside.
