2.3 System Limitations

The South Metro area is one of the key "gap" areas identified by the Statewide Water
Supply Initiative (SWSI). Although the District can currently meet its water supply
needs, it is projected that groundwater levels will continue to decline both directly
underlying the District service area as well as regionally throughout the entire South
Metro area. This is attributed to the growing demands and to the regional dependence
on groundwater. If alternative renewable supplies are not found to slow the decline of
groundwater levels, it is anticipated that the costs to maintain groundwater
production rates (e.g., redrilling wells; increased pumping energy requirements) will
eventually escalate to the point that this source is no longer economically viable.

The District has participated in regional planning studies, including the South Metro
Water Supply Study and is a participant in the proposed enlargement of Reuter Hess
Reservoir. In addition, the District is developing an IWRP, which is to evaluate the
District's demands, conservation measures, and the short-term and long-term
sustainability of the District's existing groundwater supply. This is discussed in more
detail in Section 2.5. Table 2-6 provides a brief summary on the conditions of the
water supply system.

emergencies? demands. Mandatory watering restrictions were
permanently set in May 2003 to manage peak
demands. An additional well is being brought online
in 2007 to supplement the supply. See Section 2.5.
Does the system have substantial X The District began to meter their irrigation on parks

user not previously metered. Accounting of the
2005 data did not indicate significant water loss.
Is the system experiencing a high X The District experienced substantial growth
