Sec. 21-36. - Engineering check.

In all areas where any water system having up to one hundred ninety-nine connections is to be installed that is not within the boundaries of or proposed to be annexed to a special district having the power to check and approve engineering designs and inspect and make requirements for water systems, the public health department will check all engineering designs and specify requirements, inspect and approve all construction of water systems.

(Ord. No. 1722, pt. 6, § 3: Ord. No. 4436, § 21)

Sec. 21-37. - Where no community water system.

Whenever an applicant proposes to create lots without a community water system or without supplying water from an approved source to each lot, before a lot is sold the applicant or his agents shall notify the purchaser in writing that there is no approved water supply furnished to such lot, that the development of a private water supply on the lot in question will be at the purchaser's own risk and expense, and, furthermore, that the health department accepts no responsibility for the approval or disapproval of water supplies which are to be developed privately on an individual lot basis. The applicant shall obtain a written

receipt from each original purchaser of a lot for the notice. He shall keep such receipts and a copy of the notice on file in his principal place of business in the county or other convenient location and shall make the file available for inspection by any county official or employee during ordinary business hours.

The requirements of this section may be met by the subdivision report required to be furnished to each lot purchaser under the provisions of the State Business and Professions Code, sections 11000 et seq., provided such report furnishes the information required in this section. In such event, all of the provisions of section 11000 of the State Business and Professions Code shall govern the procedure for this section.

Division 7. - Sewage Disposal

Sec. 21-38. - Purpose of division.

The purpose of this division is to insure that there will be adequate and sanitary methods provided for the disposal of sewage which will not pollute water supplies, bathing and swimming areas, nor permit sewage to come out of the surface land nor create erosion or earth subsidence or slippage problems and in general to prevent hazards to health and safety.

(Ord. No. 1722, pt. 7)

Sec. 21-39. - Community sewage systems.

In cases where a community sewage system is to be installed, conditions may be imposed by the county and the State of California Regional Water Quality Control Board relating to the location of the sewage treatment plant, method and location of plant effluent disposal, location, excavation, backfilling, and compaction of trenches for sewage lines in order to prevent erosion and damages to sewer lines or to improvements such as sidewalks and roadways crossing such lines.

(Ord. No. 1722, pt. 7, § 1: Ord. No. 4436, § 22)

Sec. 21-40. - Individual sewage systems.

In all cases where sewage disposal is to be by individual systems, in order to determine appropriate conditions to prescribe, each proposed subdivision shall be considered on its own merits. Such factors as lot size, usable lot area, topography, degree of saturation of the soil, location of the underground water table, the general soil and rock structure and geology with results of percolation and other tests, the proximity of nearby domestic water supplies, and all other pertinent factors shall be considered. Accepted sanitary engineering principals shall be employed. Industry standards may be used as guides. Among other conditions, some or all of the following may be prescribed as are deemed appropriate on the basis of known factors affecting the proposed subdivision:

(a)

Creation and use of lots or building sites may be prohibited on all or certain parts of proposed subdivisions unless connected to an approved community sewage system.

(b)

Various types of percolation tests, including "drywell" type tests or "leach line" tests, or both, may be required at locations, depths, and in numbers and under specific conditions prescribed by the county health officer. Either a tentative subdivision map or other maps may be required to show the location of such percolation tests and reports on each test may be required in writing from a registered civil engineer performing such tests.

(c)

The use of community septic tank systems may be prohibited in any case where there is danger of flooding or where adequate provisions for maintenance thereof cannot reasonably be made.

(d)

No lot shall be considered an approved building site where the installation of an individual sewage disposal system of special design has been proposed unless such installation has been first approved by the environmental health division of the public health department.

(e)

The subdivision/development review committee may require special systems to be designed by a consulting engineer who qualifies as an expert in the field of sanitary engineering.

(f)

Formation of a district or other public agency, having owners appropriate to completely handle community sewage disposal and treatment may be required in all cases where a private sewage company is to handle the community sewage disposal system in order to provide for sewage disposal in the event of business or other failure of the private company or the existence of an emergency beyond the capabilities or capacities of the private company.
