Detailed Description

Subseries : Water supply application files

Dates:
1905-1980
Physical Description:
279 microfilm reels

Scope and Content Note:

The water supply application files are largely routine in nature and documents the normal process of applying for and receiving permits for proposed public water supply systems. Typical files include application forms for permits; engineering and state health department recommendations; public hearing notices, official minutes of hearings; statutory proceedings from the Water Commission detailing their decision and copies of final permits issued by State agencies. The files also contain: incoming and outgoing correspondence between State agencies and local officials regarding technical aspects of proposed water supply systems; notices of completed applications; engineering calculations and related technical data; financial records; project review summaries and analysis reports. The application files were filmed in three different stages and the arrangement changes accordingly. Rolls 1-189 were filmed in 1965 and are arranged alphabetically by permittee. Rolls 190-219 were filmed in 1980 and are arranged numerically by project number. Rolls 220-279 were filmed in 1983 and are arranged alphabetically by permittee.

Subseries : Water supply application maps

Dates:
1905-1980
Physical Description:
90 microfilm reels

Scope and Content Note:

The water supply application maps are arranged by project number and contains maps, blueprints, profiles and drawings depicting the location of main water lines, reservoirs, aqueducts, water basins, dams, tunnels and related water works structures such as pumping stations, gatehouses and water towers. These maps and plans were submitted in conjunction with applications to create public water supply systems and provide detailed technical information regarding the proposed systems' design, layout, capacity, and limitations. Some of this detailed information includes location of springs, daily water consumption and stream flow charts, water shed calculations for annual yields and blueprints for special castings of water filter equipment. Arrangement for the water supply application maps is numerically by project number. There are a few gaps in the project numbers.
