The Angwin systems benefitted include the Howell Mountain Mutual Water Company, which serves more than 400 users in Angwin and Deer Park, the PUC system serving the campus and college housing in the community, and several small systems in the community, plus the St. Helena Hospital system which serves some of Deer Park.

New water tank for Angwin water company

Howell Mountain Mutual Water Company New Water Tank
The new HMMWC steel tank dwarfs Office Manager William Miller. It measures 54 feet in diameter and stands three stories high
Construction has been completed on a new 500,000-gallon water tank for the Howell Mountain Mutual Water Company. It will hold enough water to meet the normal needs of the 430 Angwin and Deer Park households on the system for five days. Funding for the $500,000 tank came from Napa County's Measure A program.
HMMWC's water comes from a watershed peaking at 2400-ft. elevation, 800 ft. above the village, and is captured in a series of reservoirs. It is carried through the water system plant and then into the new holding tank before release into its distribution lines throughout the community.
The HMMWC serves almost half the households in Angwin. (Others are served by Pacific Union College's wells, small neighborhood systems and private wells).
