The Midway City Sanitary District was formed in January 1939 under the Sanitary District Act of 1923.[1][3]
Following demands of an 8% pay raise from MCSD employees in 1985 and the board not offering any counterproposals, workers went on strike.[4] The strike ended after three days after a $1.25 rate hike was imposed and a 1% increase in pay was proposed by board members.[5] However, union representatives did not continue bargaining until after the 1985 election where three incumbents were on the ballot as well as a ballot measure which, if passed, would have the district place advisory measures on future ballots before increasing rates.[5] Following a 12% countywide turnout,[6] two challengers displaced two incumbents on the board.[7]
During the 1988 campaign for the board of directors, campaign mudslinging involved two incumbent directors on opposing sides, accusations of inexperience and being power hungry, and a union flyer that linked consideration of contracting out trash and sewer service to the mafia.[8] Both incumbents were reelected.[9]
In 1993, the city of Garden Grove applied to the Orange County LAFCO to takeover the Garden Grove Sanitary District and the portion of the Midway City Sanitary District within Garden Grove.[10] By September 1995, action had still not been taken on Garden Grove's application, causing frustration with local elected officials.[11] By 1997, the reorganization of the Garden Grove Sanitary District into the city of Garden Grove was complete and a portion of the territory of MCSD was removed to make the boundaries more contiguous with the city of Westminster.[3][12]
The board in 2014 censured one of its members, Al Krippner, following allegations of physical and verbal assault at a district event.[13] Krippner, along with fellow Board member Frank Cobo had previously faced controversy for charging a stipend for attending a community concert.[14]
A compressed natural gas fueling station to fuel its trucks was opened in 2015.[15][16]
