A sewage backup, a septic failure, needles left behind, or a buildup of rodent droppings in Bremerton is cleaned up by an independent biohazard or restoration company that you hire directly. First, keep people and pets out of the area and do not try to clean it yourself. Biohazard Network can connect you with an independent local company; we do not clean, haul or inspect anything.
Finding this in your home, a rental you own, or a business you manage is stressful. This page explains what the work involves, what to leave alone, and how the waste must leave the property.
What this service covers
A biohazard is any material that can carry germs or substances that can make people sick. This page covers biohazards not tied to a death or a crime: sewage backups and septic failures, sharps (needles, syringes, lancets and blades that can pierce skin), rodent droppings and nests, and contaminated material left in rentals, vacant units and businesses.
Ordinary cleaning is not enough. Sewage soaks into porous materials, which are things like drywall, carpet and insulation that absorb liquid and cannot be fully disinfected, so wiping the surface leaves contamination behind. Needles can carry bloodborne pathogens, which are germs carried in blood that can cause disease. The Washington State Department of Health (DOH) says to hire a cleaning professional if a moldy area has been contaminated by sewage.
If what you found is connected to a death, the Kitsap County Medical Examiner’s Office investigates all sudden, unexpected, or unnatural deaths in Kitsap County; see unattended death cleanup in Bremerton.
What to do first, and what to leave alone
- Close off the area. Keep children, pets and tenants away, and shut the door if you can.
- Leave needles alone. Do not pick them up or push them into a garbage bag. The Kitsap Public Health District1 (KPHD), the county health department, has guidance titled Safely Handling Sharps.
- Do not sweep or vacuum rodent droppings. DOH2 says people can be exposed to hantavirus, a virus that infected deer mice shed in urine, saliva and droppings, by breathing dust stirred up from droppings or nests. DOH says to treat all droppings as infectious and notes that a dust mask does not protect against viruses.
- Keep damaged belongings for now. The Office of the Insurance Commissioner (OIC) tells renters not to throw damaged things away yet, because the insurer may want to inspect them.
- Bring septic or sewage spill questions to KPHD1. Its programs include Drinking Water & Onsite Sewage and Water Pollution Identification & Correction, and it lists Ordinance 2025-01 : Onsite Sewage System and General Sewage Sanitation Regulations. You can reach the Kitsap Public Health District at 360-728-2235 or online.
What to expect from the company you hire
Biohazard remediation is the full process of removing contamination and making a space safe to use again. Ask the company to explain each step before it starts:
- Protective equipment: gloves, eye protection, breathing protection and protective suits for the crew.
- Containment: sealing off the work area, for example with plastic sheeting, so contamination does not spread.
- Removal: soaked porous materials are cut out and bagged. Ask for photos and a written list.
- Disinfection: applying products that kill germs on hard surfaces after cleaning.
- Odor work: this comes after the source is removed; see odor remediation in Bremerton.
- Restoration: sewage cleanup overlaps with water damage restoration, and drying and rebuilding can follow once the biohazard is gone, sometimes by a different company. See how biohazard cleanup fits with water, fire and mold restoration.
- Records: a written scope, photos and disposal paperwork for your insurer.
The OIC3 says you can ask your agent or company whether a loss is covered without filing a claim, and that most homeowner policies don’t cover gradual leaks. It also says homeowners have the right to choose their own contractor for covered repairs, and that signing a contractor’s assignment of benefit form could affect your rights.
Cleaning a former drug lab is a separate job in Washington; its decontamination workers and contractors must be certified through DOH’s Drug Lab Cleanup Program.
How to check a company
Before you hire, ask the company how it meets OSHA’s bloodborne pathogens standard4, 29 CFR 1910.1030, and whether its work follows the ANSI/IICRC S540 Standard for Trauma and Crime Scene Cleanup from the Institute of Inspection Cleaning and Restoration Certification (IICRC), a non-profit organization for the cleaning and restoration industries. You can also look the business up yourself with the Department of Labor & Industries (L&I) tool Verify a Contractor, Tradesperson or Business, and biohazard cleanup certifications explained walks through what each of these means.
The process: how the waste leaves the property
Ask the company to explain how it will sort, pack and haul what it removes.
- Sort. Biomedical waste is a legal category of waste with its own handling rules. Washington’s definition, in RCW 70A.228.010, is limited to the types it lists, including sharps waste and discarded human blood and blood products. Ask which materials from your property fall into it.
- Keep it separate. A company that collects, transports and disposes of biomedical waste must keep an operating plan that holds that waste apart from other solid waste until treatment or disposal.
- Haul it through the regulated channel. In Kitsap County, the Washington Utilities and Transportation Commission5 (UTC) and KPHD1 both regulate hauling biohazardous or biomedical waste, and companies need UTC approval and a KPHD Solid Waste Hauling Permit. KPHD publishes Permitted Solid Waste Companies in Kitsap County | 2026, so ask who will haul your waste and check the name.
- Other debris. A cleanup company that hauls site waste away in its own equipment needs the KPHD1 Site Restoration Hauler permit, which is not the biomedical waste hauling permit. Ask which permit covers which load.
- Confirm and keep records. Ask how the company confirms the area is clean, and keep every disposal document.
Sewage and biohazard cleanup in Bremerton
Bremerton is an incorporated city, and its Department of Community Development processes permit applications. If removing wet drywall or flooring leads to repairs, ask your contractor whether you need to file one. For a home, rental or business near Harborside Fountain Park, or near the Puget Sound Navy Museum by the downtown ferry terminal, KPHD1 is the health department to contact.
If the company you choose is based outside Kitsap County, ask what route it takes and how that affects when it can arrive. The county’s road links include the Hood Canal Bridge, a 7,867-foot floating bridge over saltwater, and the Agate Pass Bridge on SR 305, which is Bainbridge Island’s road link to the Kitsap Peninsula.
