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.
