WHERE & HOW WE BUILD MATTERS FOR WATER SAVINGS SMALLER LOT SINGLE FAMILY DEVELOPMENT 1 Studies found 10 to 60% water savings with increased density of single-family residences. MULTI FAMILY DEVELOPMENT 2 Multifamily units consume 35 to 50% less water than single family detached homes. If a high-density development requires cooling towers, the savings may decrease or be eliminated. EFFICIENT LANDSCAPING AND IRRIGATION 3 Landscape code requirements can reduce outdoor water use by 35-50%. INDOOR WATER USE 4 Water efficient fixtures and appliances, building and plumbing codes can have significant savings.

WATER EFFICIENT OUTDOOR WATER USE 1. Reduce the amount of water needed for irrigation by enhancing soil conditions, appropriate plant types and landscape design. 2. Decrease water waste by improving site-specific water efficiency through irrigation system design, best practices and technology. 3. Establish a maximum amount of water permitted for landscapes with water budget. 4. Limit use of potable water through alterative water sources.

MECHANISM OPTION A | LANDSCAPE ORDINANCE
MECHANISM OPTION B | WATER EFFICIENCY TAP FEE INCENTIVE Fountain, CO
MECHANISM OPTION C | WATER CONSERVATION ORDINANCE Alternative and/or Complement to a Landscape Ordinance • TIME OF DAY/SEASON : Outdoor irrigation is prohibited between 11 AM to 7 PM from May through September of each year. • WATER WASTE : Vehicle washing is only allowed with the use of a shut-off hose nozzle. • WATER WASTE : An outdoor irrigation system may not be operated while a leak from it exists. • WATER WASTE : All swimming pools, hot tubs and spas must be covered to prevent evaporation when not in use. Swimming pools may only be emptied once per year. • WATER WASTE : Water system leaks from private water lines shall be repaired by the owner or property manager within fifteen (15) days of initial notification by the County or the owner’s knowledge of the leak. Proof of repair shall be provided to the County upon completion of the repair when such notification is requested.
