Breaking Down the Water Supply
Water is a is the most abundant resource on the planet and essential to all known forms of life.
Water supply system: The collection, treatment, storage, and distribution of potable water from source to consumer.
Water surcharge: Imposition of a higher rate on excessive water use.
Water system: A river and all its branches.
water supply forecasting Predicting the total (spring and summer) streamflow from snowmelt and rain which occurs during snowmelt.
water supply main Any water supply pipeline that is part of a waterworks distribution system.
Water supply - The basic origin of a water, either a surface source (such as a lake, river, or reservoir) or a subsurface source (such as a well). After treatment and pumping via pipe lines, the treated and pumped water becomes a water supply.

Drinking Water Supply
As defined by section 101(7) of CERCLA, any raw or finished water source that is or may be used by a public water system as defined in the Safe Drinking Water Act, or as drinking water by one or more individuals.
Interstate Carrier Water Supply: A source of water for drinking and sanitary use on planes, buses, trains, and ships operating in more than one state. These sources are federally regulated.
EPA has initiated a number of voluntary programs in which industrial, or commercial or "partners" join with EPA in promoting activities that conserve energy, conserve and protect water supply, ...
ENVIRONMENTAL FACTORS - WATER SUPPLY
Water availability has a strong influence on photosynthesis in tree species. Both excesses (flooding) and deficits (drought) in water decrease rates of photosynthesis.
In the western US, where snowpack provides free storage of most of the water supply, reduced snowpack will make less water available in summer. Coastal areas will become more vulnerable to storm surges as sea level rises.
American public water supply and treatment facilities use about 56 billion kilowatt-hours (kWh) of electricity annually—enough to power more than 5 million homes for an entire year.
water supply system A facility designed for the distribution of potable water, typically including storage tanks and a network of pipes. water table The level of ground water. The upper surface of the saturated zone in an unconfined aquifer.
The costs involved with recycled water typically exceed those of standard potable water in most regions of the world, where a fresh water supply is plentiful.
the measurement of constituents in a water supply which determine alkaline conditions. The alkalinity of water is a measure of its capacity to neutralize acids. See pH.

Open vertical gap or empty space that separates drinking water supply to be protected from another water system in a treatment plant or other location. The open gap protects the drinking water from contamination by backflow or back siphonage.
Diversion: 1. Use of part of a stream flow as water supply. 2. A channel with a supporting ridge on the lower side constructed across a slope to divert water at a non-erosive velocity to sites where it can be used and disposed of.
Infiltration constitutes the sole source of water to sustain the growth of vegetation and it helps to sustain the ground water supply to wells, springs, and streams.
conductance : A rapid method of estimating the dissolvedsolids content of a water supply.
Hydrological (water) cycle is he cycle of the earth's water supply from the atmosphere to the earth and back which includes precipitation, transpiration, evaporation, runoff, infiltration, and storage in water bodies and groundwater.

Nitrate
Plant nutrient and inorganic fertilizer that enters water supply sources from septic systems, animal feed lots, agricultural fertilizers, manure, industrial waste waters, sanitary landfills and garbage dumps.(1) ...
AUGMENTATION: The process of adding recycled/reclaimed water that has received advanced treatment to an existing raw water supply (such as a reservoir, lake, river, wetland, and/or groundwater basin) that could eventually be used for drinking ...
OCWD Annual Engineer's Report. An annual report on the groundwater conditions, water supply, and basin utilization to be delivered in writing to the Secretary of OCWD on the second Wednesday in February of each year.
Back Pressure- A pressure that can cause water to backflow into the water supply when a user's waste water system is at a higher pressure than the public system.
Practical control measures used to improve the basic environmental conditions affecting human health, for example clean water supply, human and animal waste disposal, protection of food from biological contamination, and housing conditions, ...
particulate pollution - pollution made up of small liquid or solid particles suspended in the atmosphere or water supply.
passive solar - using or capturing solar energy (usually to heat water) without any external power.
Wellhead Protection Program (WHPP): A program to protect public water supply systems from potential sources of groundwater contamination.
Control Valve: A valve used to control the water supply of a water-based fire protection system.
Backflow: A reverse flow condition, created by a difference in water pressures, which causes water to flow back into the distribution pipes of a potable water supply from any source or sources other than an intended source.
Salt water intrusion: Process by which an aquifer is overdrafted creating a flow imbalance within an area that results in salt water encroaching into fresh water supply.
Saturated thickness: Total water-bearing thickness of an aquifer.
liquid, or contained gaseous materials discarded from industrial, commercial, mining, or agricultural operations, and from community activities. Solid waste includes garbage, construction debris, commercial refuse, sludge from water supply or waste ...
Even though rains continuously replenish the clean water supply, we have polluted the rivers, lakes and streams making them unsuitable for drinking or agriculture. Further, we are rapidly draining the underground aquifers which took eons to fill.
is significantly below normal levels, causing water levels to drop and vegetation to die. This extended period of dry weather usually lasts longer than expected and leads to measurable losses for a human community (crop damage, water supply shortage).
However, in underdeveloped countries, the concerns would relate to more basic aspects such as conditions causing the spread of tuberculosis or dysentery, or problems relating to malnutrition, or the lack of a safe drinking water supply.
Fertilizers contain excess nutrients and when these enter the water supply, perhaps due to water running off a field into a river, the nutrients cause an imbalance in the make up of the water.
