About Us
HOW DOES CLEAN WATER BECOME CONTAMINATED?
SFPUC actively protects the natural water resources under its stewardship. Their annual Hetch Hetchy Watershed analysis evaluates environmental conditions, water quality, potential contamination sources, and the effectiveness of management actions implemented by SFPUC and partner organizations like the National Park Service.
SFPUC also conducts comprehensive surveys of the local Alameda and Peninsula watersheds every five years. These assessments have identified both wildlife activity and human behavior as potential contamination sources. The most recent local sanitary review was completed in 2016, covering the period from 2011-2015. This information is available for public review at the SWRCB Clean Water Division office (510-620-3474).
The Hayward City Council serves as the governing authority for the Hayward Water System. Council meetings are held at 7:00 p.m. on Wednesday evenings (except the second and fifth Tuesdays) at Hayward City Hall. The SFPUC oversees the wholesale water supply system that delivers water to Hayward, meeting on the second and fourth Tuesdays at 1:30 p.m. at San Francisco City Hall, Room 400. The public is encouraged to participate in these meetings.
Some individuals may be more vulnerable to water contaminants than the general population. People with compromised immune systems (those undergoing cancer treatment, organ transplant recipients, people with HIV/AIDS or other immune disorders, some elderly individuals, and infants) may face increased risk from infections. These individuals should seek advice about municipal water from their healthcare providers. USEPA/CDC guidelines on appropriate measures to reduce infection risks from Cryptosporidium and other microbial contaminants are available via the Safe Drinking Water Hotline at 800-426-4791 or at www.epa.gov/safewater.
Water sources (both tap and bottled) typically include rivers, lakes, streams, ponds, reservoirs, springs, and wells. As water travels across land or through soil, it dissolves naturally-occurring minerals and, in some cases, radioactive materials, while also potentially collecting substances from animal presence or human activities.

In 1843, the Mexican government granted officer and surveyor Guillermo Castro nearly 27,000 acres of land. He named it Rancho San Lorenzo, encompassing what is now Hayward and Castro Valley. Castro operated his ranch from a home located at the site of the historic City Hall on Mission Boulevard.
The gold discovery in January 1848 transformed California dramatically. Thousands rushed to Northern California hoping to strike it rich. Many, like William Hayward, quickly discovered that gold mining was difficult work with limited rewards. While traveling from the gold fields to San Francisco in 1851, Hayward passed through Castro's land. Impressed by what he saw, he established a camp at Palomares Canyon's mouth, planning to cultivate a few acres.
Castro agreed to sell Hayward several acres in what is now downtown Hayward. In 1852, Hayward established a small general store at A Street and Mission Boulevard. This location became an important stop on the Oakland-San Jose route, generating so much business that Hayward built a hotel that became the renowned Hayward's Hotel.
Castro attempted to capitalize on the region's growing popularity by commissioning a town survey in 1854, which became the foundation for modern downtown Hayward. Unfortunately, Castro's financial mismanagement forced him to gradually reduce his holdings until 1864, when the county seized his remaining lands to settle debts, selling them for $30,000. Castro relocated his family to South America, never returning.
Meanwhile, more settlers arrived, establishing fruit orchards, cattle ranches, businesses, and other enterprises. In 1860, the U.S. post office established a location at "Haywood," operating from William Hayward's A Street store. Most locals, however, referred to the growing community as "Hayward's," as William Hayward was not only the first American settler but also served variously as postmaster, justice of the peace, county supervisor, and road master.
When the town incorporated in 1876, it was officially named "Haywards." The "s" was dropped in 1893, creating the current name "Hayward." The favorable climate, fertile soil, and convenient location in the greater Bay Area metropolitan region spurred tremendous growth over decades. The most significant expansion occurred after World War II when housing developments replaced farms and ranches. With affordable housing and abundant employment opportunities throughout the region, the population surged from 14,000 in 1950 to 72,000 in 1960 and continues to grow, now exceeding 150,000.
Today, Hayward ranks among California's ten most diverse communities. Just as William Hayward recognized this as an ideal place to settle and build his life over 160 years ago, residents today continue to find Hayward the perfect place to live!

- My water appears rusty or reddish. What should I do?
Sometimes sediment gets disturbed in water mains due to high demand (such as firefighting) or routine maintenance flushing by the Water and Sewer Division. The water has been properly treated and disinfected, but picked up iron (rust) on its journey to your property. We recommend running your cold water tap for several minutes until clear. Avoid doing laundry until the water clears, as clothes may become stained by the iron. If the problem persists, contact the Water and Sewer Division at 607-272-1717.
- I have no water service. Who should I contact?
If you have no water and have verified that all plumbing shut-off valves are open, contact the Water and Sewer Division. During business hours (Monday-Friday, 7 a.m. to 3:30 p.m.), call 607-272-1717. After hours, call 607-273-4680.
- There's water flowing from the ground or a damaged fire hydrant. Whom should I contact?
Report potential water leaks or damaged hydrants to the Water and Sewer Division. During business hours (Monday-Friday, 7 a.m. to 3:30 p.m.), call 607-272-1717. After hours, call 607-273-4680.
- My sewer line is backed up. Who covers the cost of clearing it?
The answer depends on the blockage location. If your sewer lateral backs up, we recommend contacting a local drain cleaning company or plumber who can quickly identify the blockage location. If the problem is between your home and the clean-out on your property line (most common), the property owner is responsible for costs. If the issue is between the clean-out and the sewer main in the street, the Water and Sewer Division should be contacted to make repairs at no cost to the property owner.
- How do I apply for new water or sewer service?
Contact the Water and Sewer Division at 607-272-1717. For new water service, city crews will tap the water main and run service to a curb box at your property line. The initial installation cost is billed to you, but the city maintains the service from the main to the curb box indefinitely at no additional cost. Connecting from the curb box to your water meter is your responsibility, typically done by a licensed plumber.
For new sewer service, city crews will install a lateral from the main to a clean-out at your property line. You'll be billed for initial installation, but the city maintains the lateral from the main to the clean-out indefinitely at no cost. Connecting from the clean-out to your building is your responsibility, typically done by a licensed plumber.
