A domestic water system in the town of Manson was originally constructed and privately owned by J.R. Laycock sometime around 1910. Negotiations between the Lake Chelan Reclamation District and Mr. Laycock to purchase the system began in May of 1920 with a final settlement price of $2,289 being paid in February of 1922.

The Lake Chelan Reclamation District made many improvements and expansions to the system between 1922 and 1971. A study undertaken in October 1971 indicated that the Manson Intake was at capacity to meet peak daily demands with no capacity for fire flows during peak demand periods. The two 400 gpm pumps would run nearly continuously for 24 hours and the 150,000-gallon reservoir had no storage for fire flows during July and August. Much of the distribution system was undersized for providing fire flows with many dead end lines.

The rebuilding of the irrigation system in 1971-1975 gave the District an opportunity to lay several miles of domestic water lines into the rural areas. Domestic lines were laid in the same trench as the irrigation distribution lines under construction. District crews were utilized to accomplish this task, and in doing so, expanded the service area quite significantly. In 1974, the Lake Chelan Reclamation District constructed a second domestic intake called the Lakeshore Intake. The new pump station contained two pumps with a combined capacity of 1,300 gallons per minute. The station was located on District property that had been used historically to pump supplementary irrigation water into the old irrigation system. The District abandoned the irrigation station and used the station's 24-inch discharge line for the new Lakeshore Intake. Water was pumped through the 24-inch steel line to a new 1.0 million-gallon reservoir located adjacent to Summit Avenue.

In 1982 the Manson Intake was rebuilt to include three pumps with a total capacity of 3,000 gallons per minute. A new 16-inch discharge line was installed and in 1985 a new 1.0 million-gallon reservoir was constructed above Division Street. By 1990 over 45 miles of distribution system served customers in the greater Manson area.

In 1991, the Washington State Department of Heath directed the Lake Chelan Reclamation District to begin planning for a Water Treatment Plant to filter the domestic supplies coming from Lake Chelan. Studies were undertaken to determine if it was more efficient to combine the intakes for the District with the City of Chelan and build only one treatment plant. The study concluded that it would be more cost effective to build a plant at each location. In 1997 construction began on a four million gallon per day treatment plant together with pipelines and other appurtenances to bring untreated water from both the Manson Intake and the Lakeshore Intake to the treatment plant located near the Manson Reservoir. Construction included a new 1.25 million gallon finished water reservoir. Total cost of the project completed in 1999 was $7.4 million dollars.
