STATEMENT OF WORK (SOW)

Rehabilitate Well Houses 2/6 and 3/7 El Portal, CA Mariposa County, CA Yosemite National Park 3/1/24

1. General Information Yosemite National Park is located in central California, in the Sierra Nevada Mountain range. The park was established by Congress on October 1, 1890. The Park’s mission is to protect, preserve, and interpret the natural, cultural, and historical resources for the benefit and inspiration of present and future generations. There are over 5 million visitors annually to the Park. El Portal is an administrative area to the West of the Arch Rock entrance, which provides facilities and utilities for throughout the Park.

2. Facility Background Yosemite National Park has a series of wells, well houses, and water storage tanks that provide potable water for the entire Park. Well houses 2/6 and 3/7 are two of the well houses in the El Portal area that provide water to Tank No. 3, which is a 500,000-gallon water tank. This water tank distributes water the El Portal community including the administrative site, residents, and businesses.

EXISTING WELL HOUSE NO. 2/6

The existing well house 2/6 includes a water well located inside the well house, as well as a well located outside of the well house. The raw water is pumped through the well house in above ground piping, which includes a series of valves, check valves, sampling ports, and meters. The raw water is treated with sodium hypochlorite for disinfection. There is also a SCADA system to monitor the status of the local pumps, and the off-site well pumps and water tanks throughout the system. The existing SCADA system does not provide the capability of remote controls in any part of the system. The piping within the well house includes a mixture of brass fittings, cast iron pipe and galvanized pipe. All the piping, as well as the various fittings are very old and in need of replacement. The chemical tanks and pumps have also exceeded their life span; and need replacement. In addition, an eye wash station needs to be installed in the well house to meet the code requirements relative to the chemical storage within the building. The existing well house structure and concrete flooring are in good shape for the most part. The exterior has weathered and needs to be painted, and the roof and soffits need replacement.

EXISTING WELL HOUSE NO. 3/7

The existing well house 3/7 does not have a well located inside the building, rather there are two wells located outside of the well house. The raw water is pumped through the well house in above ground piping, which includes a series of valves, check valves, sampling ports, and meters. The raw water is treated with sodium hypochlorite for disinfection and zinc orthophosphate to inhibit corrosion. The existing roof is a cedar shake roof which is in poor condition. There is also a SCADA system to monitor the status of the local pumps, and the off-site well pumps and water tanks throughout the system. The existing SCADA system does not provide the capability of remote controls in any part of the system. The piping within the well house includes a mixture of brass fittings, cast iron pipe and galvanized pipe. All the piping, as well as the various fittings are very old and in need of replacement. The chemical tanks and pumps have also exceeded their life span; and need replacement. In addition, an eye wash station needs to be installed in the well house to meet the code requirements relative to the chemical storage within the building. The existing well house structure and concrete flooring are in good shape for the most part. The exterior has weathered and needs to be painted, and the roof needs replacement and upgraded to metal soffits and roofing material.

3. Scope of Proposed Work The scope of work for each well house is as follows:
