Residential Wastewater Disposal Guidelines

Do NOT flush "flushable" wipes

Today many personal hygiene wipes and cleaning products are marked as being "flushable". Despite the confusing labels, you should never flush "flushable" or "disposable" products as they can clog sewer pipes causing blockages, back-ups and overflows.. The only items you should flush are human waste and toilet paper.  

Keep drains free of cooking fats, oil and grease

Cooking fats, oils and grease can block sewer lines, causing raw sewage to back up into your home or into neighborhood streets and storm drains without any treatment. Keep your sewer lines free by scraping cooking fats into the garbage not down the drain.

Do NOT use your garbage disposal with hot water or detergent to wash grease down the drain

 Home garbage disposals do not remove grease from the plumbing system. The hot water will cool down in the pipes causing fats and grease to coagulate, potentially clogging the pipes. Detergents that claim to dissolve grease may cause blockages to occur further down the pipeline.

May I throw cooking oil in the trash

Small amounts of oil can be placed in tightly sealed, unbreakable containers in the trash. It is not recommended to dispose of large amounts in the trash as containers may leak, causing problems with garbage trucks and at solid waste facilities.

Paint, motor oil and other household hazardous waste items

Never pour unwanted household chemicals, such as paint thinner, pesticides, fertilizes or automotive waste down the drain. Take these items to a Riverside or San Bernardino County household hazardous waste collection center (Riverside County 800.304.2226).
