Solid Waste Collection, Recycling, and Disposal

This page outlines Washington State's solid waste management system, including local government responsibilities, planning requirements, collection service options, bidding and contracting requirements, organic materials, and more.

Overview

RCW 70A.205.010 establishes a statewide program for solid waste handling, recovery, and/or recycling to prevent pollution and conserve resources of this state. The Washington State Legislature assigns primary responsibility for solid waste handling and planning to local governments while “reserving to the state…those functions necessary to assure effective programs.”

While Washington cities, towns, and counties have primary responsibility for managing solid waste collection and disposal, they are not required to directly provide those services (see RCW 35.21.120, RCW 35.21.130, and RCW 36.58.040). Moreover, the relevant statutes do not mandate that all residents and businesses have trash collected by any public or private hauler.

The State Solid and Hazardous Waste Plan created by the Washington State Department of Ecology (Ecology) guides the management of waste and materials in the state, helping local governments stay in compliance with the statewide purposes, goals, and rules that establish minimum functional standards for solid waste handling in Chapter 70A.205 RCW.

Solid Waste Management Plans (SWMPs)

RCW 70A.205.040 requires each county within the state, in cooperation with the cities and towns within that county, to prepare a coordinated, comprehensive solid waste management plan (SWMP). State law requires comprehensive solid waste management plans be reviewed and updated every five years (RCW 70A.205.075).

The plan must include the following items listed in RCW 70A.205.045:

  • An inventory of all existing solid waste handling facilities and their deficiencies;
  • A list of long-range needs for solid waste handling facilities;
  • A waste reduction and recycling element; and
  • Ecology's Contamination and Reduction and Outreach Plan (CROP) for counties of over 25,000 people. The statute encourages incorporation of food waste reduction strategies consistent with the department's Use Food Well Washington Plan (2022).

Counties may impose a fee on solid waste collection companies operating within unincorporated areas to pay for administrative and planning expenses related to the solid waste management plan. See RCW 36.58.045.

For more guidance on developing a SWMP, see the Recommended Resources section of this page.

Examples of SWMPs

Solid Waste Collection Options

Cities, towns, and counties have the following options regarding how to provide solid waste and recycling collection services:

Option 1: Local Government Provides Collection Service

Many local governments in Washington require all individuals to sign up for solid waste collection. Others provide municipal collection service but do not require participation. Below are examples of cities requiring universal, compulsory collection.

Option 2: Municipality Contracts with Other Municipalities

Under the Washington State Interlocal Cooperation Act (Ch. 39.34 RCW), a municipality can contract with another local agency, city, or county for solid waste collection services. Examples of cities utilizing interlocal agreements for solid waste collection services include:

Option 3: Municipality Contracts with Private Firm While Still Controlling Billings and Rates

Municipalities may enter into contracts with waste haulers for collection and recycling services, but continue to provide billing and control rates. Below are selected code provisions that have adopted this approach; also see the examples of solid waste collection contracts and solicitations later on this page.

Option 4: Municipality Contracts with Private Firm with Municipality Only Controlling Rates

A municipality can contract with a private waste hauler for collection and recycling services, including billing, while the municipality controls rates. Below are selected examples of these code provisions.

Option 5: Municipality Licenses or Franchises to Private Firm

Municipalities may grant a franchise or license to a waste hauler or haulers, with the Washington Utilities and Transportation Commission (UTC) controlling billing and rates. Below are selected examples of these code provisions.

Option 6: UTC Sets Rates and Service Area

Although the state requires counties and cities to plan for solid waste management and gives them the authority to provide solid waste collection services (or contract for the service), they are not required to provide collection services. If a municipality chooses this option, the UTC sets the service area and the rates to be charged by private firms that serve the municipality.

Below is information from the UTC on companies they regulate:

In case of an annexation, a city is required to grant a franchise to the UTC-regulated solid waste collector that served the annexed area for at least seven years after it notifies the UTC of its intent to provide or regulate collection services inside the city — see RCW 35A.14.900 (code cities) and RCW 35.13.280 (other cities and towns). RCW 35.02.160 contains a similar provision for newly incorporated cities and towns.

Below is an example of post-annexation franchise agreements granting UTC-regulated solid waste companies continued authority to provide collection services:

Solid Waste Contracts & Solicitations

Cities, towns, and counties may contract with businesses for a variety of tasks related to solid waste management. The bidding and contracting requirements will vary depending on the task; common examples are below.

Solid Waste Collection Services

Agencies have considerable flexibility when soliciting solid waste collection services. Solid waste collection is considered a purchased service and has no specific bidding requirements in state law. Agencies should follow their local procurement policies for soliciting and entering into a contract for solid waste collection.

Below are selected examples of contracts and bidding documents:

Clarification: Agencies should follow their local procurement policies and are not required to follow the competitive negotiation process in RCW 35.21.156 (cities and towns) or RCW 36.58.090 (counties) when contracting for solid waste collection services.

The competitive negotiation process is established specifically for contracting for design, construction, or operation of solid waste facilities and related services. See Ventenbergs v. City of Seattle (2008).

Architecture & Engineering

Contracts for solid waste architecture and engineering must follow the qualifications-based selection (QBS) process for professional architecture & engineering services in accordance with chapter 39.80 RCW and local policies. These contracts are awarded based on qualifications, not cost.

Below is an example:

Solid Waste Facilities

When contracting for solid waste facilities, cities and counties may have a few options depending on the specific nature of the contract:

Rate Setting & Rate Increases

Municipalities often use rate studies to establish garbage rates and increases. Rate studies account for operations and maintenance, debt service, and future capital costs. There is no cap on solid waste rate increases; utility (enterprise) funds are intended to be self-supporting, meaning rates should cover all expected expenditures.

While cities and counties often hold public hearings for utility rate changes, a public hearing is not required by state law.

However, cities and towns must notify the public of any solid waste rate increases at least 45 days before the increase takes effect—either by mailing a notice to each affected ratepayer, or by publishing the notice in a newspaper of general circulation in the collection area once per week for two consecutive weeks. This applies whether the city or town contracts for solid waste collection or provides collection directly. See RCW 35A.21.152 (code cities) and RCW 35.21.157 (other cities and towns). We are not aware of any similar statute for counties.

Below are selected examples.

Rate Studies

Rate Notices

Collection of Overdue Accounts

MRSC’s page on Collection Practices for Delinquent Utility Accounts provides information on collecting overdue accounts, including utilizing collection agencies and payment plans. Unlike discontinuing water and electricity utility services, state law does not provide limitations on when solid waste collection may be discontinued for nonpayment.

One available option for cities and towns is to file a lien for garbage collection and disposal services on properties—see RCW 35A.21.060 (code cities) and RCW 35.21.140 (other cities and towns).

Counties that have established solid waste collection districts and use private haulers have a lien option under RCW 36.58A.040.

Solid Waste Utility Taxes

Cities and towns can (optionally) impose a utility tax on the income of a public or private solid waste utility providing service within the city or town boundaries—even on the municipality’s own utility.

There is no maximum tax rate for utility taxes on a solid waste utility, and the revenues may typically be used for any lawful governmental purpose. A utility tax is imposed on the gross revenues of the utility business itself, not the individual utility customers.

While municipally owned utilities are required to disclose the utility tax rate for water, sewer/wastewater, and stormwater utilities under RCW 35.92.460, they are not required to disclose the utility tax for solid waste utilities.

For more information, see our page on Utility Taxes.

Organic Waste Management

In recent years, the Washington State Legislature has adopted laws addressing organic materials management, with the goal of reducing and diverting organic waste from landfills. RCW 70A.205.540 (amended in 2025) requires jurisdictions to provide year-round source separated organic solid waste collection services to single-family residents and certain nonresidential customers. The statute includes exceptions based on jurisdiction size, population density, and proximity to organic materials management facilities. The Department of Ecology aims to cut the amount of organic material sent to landfills by 75% by 2030, using 2015 levels as a baseline. Additionally, it seeks to decrease the disposal of edible food in landfills by 20% by 2025. 

Below is a summary of state law requirements impacting local governments; however, Ecology’s Organic and Food Waste division includes more comprehensive resources on this subject.

Compost Procurement Ordinances

Composting organic waste such as food scraps and yard waste provides a number of benefits, including reducing the amount of waste sent to landfills or incinerators, reducing greenhouse gas emissions from landfills, and providing soil benefits for the users of the finished compost.

Counties and cities with populations greater than 25,000 must adopt compost procurement ordinances (RCW 43.19A.150). This requirement also applies to all cities and counties, regardless of population, that provide organic material collection services under Chapter 70A.205 RCW. The purpose of the compost procurement requirements is to strengthen markets for the increasing amount of compost generated statewide by requiring local governments to plan for the use of compost in landscaping projects, construction and postconstruction soil amendments, and other projects.

Any jurisdiction required to adopt compost procurement ordinances must also develop strategies to inform residents about the value of compost and how the jurisdiction uses compost. Jurisdictions must submit annual reports to Ecology by March 31 of each year on the previous year's compost procurement activities.

For more information, see MRSC’s blog The Breakdown of Compost Product Purchasing (2023) and Ecology’s Resources on Compost Procurement Ordinances.

Examples of Compost Procurement Ordinances

Siting of Organic Materials Management Facilities

Any development regulations to implement comprehensive plans under Chapter 36.70A RCW (Growth Management Act) or Chapter 36.70 RCW (Planning Enabling Act) that are developed, updated, or amended after January 1, 2025, must allow for the siting of organic materials management facilities in the areas identified in RCW 70A.205.040(3)(a)(i), which puts priority areas in industrial zones, agricultural zones, or rural zones (see RCW 36.70A.142 and RCW 36.70.330).

Organic Waste Collection Requirements

Beginning April 1, 2027, in each jurisdiction that implements a local solid waste plan under RCW 70A.205.040, year-round, source-separated organic solid waste collection services are required to be provided to all residential customers (except multifamily residences) and all non-residential customers who create more than .25 cubic yards of organic waste per week. See RCW 70A.205.540.

RCW 70A.205.540 includes several exceptions to its applicability that account for factors such as total population, solid waste generation levels, population density, urban growth area boundaries, and availability of organic waste processing facilities. Cities and counties that already had organics collection service as of January 1, 2024 are not required to provide year-round service as long as weekly service is provided at least 26 times per year.

By April 1, 2030, the source-separated organic solid waste must be provided on a nonelective basis unless a customer manages that waste on-site or self-hauls the material. Also, all jurisdictions’ source-separated organic solid waste collection services must include the year-round acceptance of food waste, either separate from or commingled with other organic materials.

For more information on the recent legislative changes impacting organic materials collection and management, see the Ecology pages on Compost and Organics Management Law.

Grant Programs for Organic Waste Diversion and Food Waste Reduction

The 2024 legislative session established a new grant program related to food waste reduction and organic material management policy implementation. These grants will be administered by the Washington Center for Sustainable Food Management (“the Food Center”), which was established in RCW 70A.207.020. The priority areas for funding are for programs and policies that:

  • Prevent the creation of unsold and uneaten food from food businesses, and/or improve their food donations process;
  • Improve transportation and cold storage in the rescued food supply chain;
  • Support the creation and expansion of food waste reduction programs to benefit vulnerable communities;
  • Invest in food waste tracking and data analytics pilot strategies; and
  • Support the implementation of Washington’s organics management laws.
