WATER SUPPLY & SEWER
Water is a precious resource. Use it wisely.
Water and Sewer in the Valley Springs Area
Most of the “town center” of Valley Springs gets its water from Valley Springs Public Utility District (VSPUD), whose water source is an underground well (groundwater). VSPUD also provides sewer service to the town area. Some commercial areas to the south are served by Calaveras County Water District (CCWD).
Outside of these areas, most people are on private wells and septic tanks. Many wells have good quality reliable water; others range in quality and reliability of water supply. Some wells have failed; some have had to be deepened and/or had filtering and treatment systems installed.
New Hogan Reservoir
During an average year, CCWD is entitled to approximately 31,000 acre-feet of water from New Hogan Reservoir for its customers. Actual water use averages around 4,000 acre-feet. Stockton East Water District (SEWD) uses all or part of the unused portion.
15,000 acre-feet is the “minimum pool.” When water levels in the reservoir are too low, it’s called “Dead Pool storage.” Water quality becomes a problem, and treatment is more difficult (due to high concentrations of sediment and manganese).

Mandatory Stage 3.5 Water Conservation
On May 13, 2015, due to Governor Brown's January 'State of Emergency' drought order and State Water Resources Control Board emergency water regulations May 5, the Calaveras County Water District adopted new watering restrictions, "Stage 3.5 Mandatory Water Conservation Measures." These restrictions apply to all 12,600 CCWD customers. CCWD is expected to achieve a collective reduction of 32 percent countywide. Click here for new watering restrictions, which include limiting outdoor irrigation to two days a week. On June 16, 2015, CCWD issued a Press Release that provides information regarding CCWD's mandatory water conservation standard being reduced from 32 percent to 16 percent by the State Water Resources Control Board.
Mandatory Stage III Water Conservation
In May 2014, due to continued drought, the California State Water Resources Control Board sent CCWD a "Notice of Unavailability of Water and Immediate Curtailment." CCWD was ordered to cease water rights diversions except for human health and safety. To ensure maximum conservation, on June 11, 2014, the CCWD Board of Directors adopted Mandatory Stage III Water Conservation Measures. These restrictions apply to all 12,600 CCWD customers countywide. The goal is to reduce water use in the entire district by 35%.

Voluntary Water Conservation, System Limitations
Water availability is affected by rainfall, storage capacity, usage, and delivery systems. When rainfall is below average for 3 years, the water supply in Hogan Reservoir can drop to under 20% of storage capacity. CCWD asks customers to use voluntary water conservation measures during the summer.
In addition to water supply and storage, “system design capacity” limits how much water can actually be delivered during periods of high demand. The existing pipes underground, the pumps for the water, the treatment plant, and the storage tanks all limit water availability.

Rancho Calaveras Water Outage July 2006
In April 2006, the Valley Springs area suffered extensive flooding due to heavy winter and spring rainstorms. New Hogan Reservoir was filled to its maximum water storage capacity. Despite this full reservoir, due to an extensive July heat wave, a weekend power outage, and limitations of existing infrastructure (pipes, pumps, filters, storage tanks), some Rancho Calaveras residents suffered water outages in July 2006. Water restrictions and conservation were necessary.
