Article 414-4.2. General |
§ 414-4.601. Individual water system—Quality, quantity.
(a)
Quality.
(1)
Bacteriological. The water from an individual system, installed for domestic use, shall be examined by the health officer on completion of the system. Subsequent testing shall be performed by a laboratory approved by the California Department of Health Services and at the expense of the owner of the individual water system. The water tested shall be bacteriologically acceptable for domestic use.
(2)
Chemical. An analysis for specific organic or inorganic chemical constituents in the water may be required when there is evidence that such constituents may be present and which are considered by the health officer to be a risk to human health.
(3)
Physical. Tests for odor, color, turbidity, pH or other physical properties of the water may be required when there is evidence the water may not be acceptable or potable for human consumption.
(b)
Quantity. Applications for building permits or certificates of occupancy for a structure requiring an individual water supply system shall, prior to their issuance, be submitted to the health officer for review to determine if the water supply source will provide minimum of quantities in accordance with the following:
(1)
Wells. Sustained yield or pumping tests may be required by the health officer. The well yield shall be determined from pumping tests or historical data acceptable to the health officer. The well or wells shall yield a minimum three gallons per minute and a minimum storage capacity of one thousand gallons in a storage tank shall be provided. No storage is required if the well yield is five gallons per minute or greater. Sustained yield tests, when required, shall be conducted in accordance with the procedures described in Title 22, Section 64563 of the California Administrative Code.
(2)
Other Surface Sources. Yields and required storage capacity shall meet the same minimum requirements as for wells. Adequate documentation that the surface sources are perennial shall be provided.
(c)
Director of Building Inspection. When the building inspection director is advised by the health officer that it has not been demonstrated that a water source exists complying with this chapter and that such lack is a danger to or likely to cause public health problems, he may withhold the issuance of the requested building permit or certificate for a structure.
