Notes
Survey number HAER CT-145-B
Significance: The Dayville Mills Hydroelectric Facility powerhouse was built c1925 to provide the Dayville Mills Complex with electrical power to drive textile machinery. The powerhouse includes a free standing brick building, headgate, penstock, turbine, generator, and governor all of which were retired from service c1962 and survive in 1993. In 1858 Sabin L. Sayles and Harris C. Sayles of Pascoag, RI, built a textile mill building in Dayville. In the mid 1800's the area was characterized by an influx of out of state firms moving in and expanding the textile industry. In 1883 a 50 foot by 200 foot 4-1/2 story brick structure was erected by the Sabin L. Sayles Co. This woolen goods manufactory became the principal industrial institution in the village of Dayville. In 1993 the building stands vacant.
