The subdivider must possess, and provide to the county, written documentation (water right certificate and the like) which grants the legal right to the required amount of water to each lot within the proposed subdivision.
(b) Where a well is proposed to be shared between two or more lots, written approval from the Weber/Morgan Health Department that the proposed well meets all requirements is required to be submitted with the preliminary plat application. A maintenance agreement between the lot owners is required to be executed prior to plat recordation which identifies maintenance responsibilities, easements and wellhead protection requirements.
(c) Water service lines to lots shall be at least three-fourths inch diameter. Greater diameter may be required due to grade, pressure, Building Code and fire sprinkler requirements.
(d) Water rights and well permits are required as a condition of approval for each lot and shall remain with the lot and shall not be transferred separately from the lot.
(2) Where an approved culinary water supply system is available or proposed, the county will require to be installed, at the subdivider’s expense, water mains, valves, hydrants, service laterals, meter yokes, boxes, lids, meters (when required prior to the home or building construction by the water provider) and appurtenances to each lot within the subdivision. The source shall be capable of delivering 800 gallons per day per equivalent residential connection for indoor use and three gpm per irrigated acre for outdoor use.
(a) Required water storage shall be calculated by the cumulative requirements of culinary, irrigation and fire suppression requirements, but shall be no less than 400 gallons per equivalent residential connection for indoor use, 1,813 gallons of storage for each irrigated acre, and 120,000 gallons for fire suppression.
(b) Water service lines to lots shall be at least three-fourths inch diameter. Greater diameter may be required due to grade, pressure, Building Code and fire sprinkler requirements.
(c) Water and connection rights are required as a condition of approval for each lot and shall remain with the lot and not be transferred separately from the lot.

If individual on-site septic tanks are proposed, written approval must be provided from the Weber/Morgan Health Department.
(E) Subsurface water drains may be installed at the option of the subdivider or as required by the County Engineer. All plans for such subsurface drains proposed by the subdivider shall be reviewed by the County Engineer. All such subsurface drains shall meet the minimum requirements for design and construction of such drains, as specified by the county. Upon final inspection and approval by the County Engineer of such subsurface water drainage system, the owner shall thereafter maintain the system. The owner shall cause to be recorded protective covenants providing for mandatory assessment and payment of fees for each lot or parcel located within the subdivision which covenants shall run with the land and be binding upon all successors in interest and assigns of the owner. The maintenance assessments shall constitute a lien on each lot or parcel located within the subdivision and may be enforced in accordance with the terms of any applicable subdivision subsurface water drain maintenance agreement and the protective covenants referred to hereinabove. The county may, based on the findings and recommendations of a geotechnical report and other relevant analysis, require that no basements are constructed in certain areas with identified high water tables. If no basements are allowed, a note shall be placed on the plat reflecting this requirement.
(F) Streetlights shall be provided in all subdivisions where required by the County Engineer for intersection safety or other public safety purpose as set forth herein. The subdivider shall pay for the installation, including all electrical service lines.
