options and provide the District guidance in selecting a group of options that are best
suited for the District's needs. The development of the IWRP is divided into a four
step process that includes:

. Task 1: Investigating the current and future water demands

. Task 2: Assessing the effects of existing and future water conservation efforts

. Task 3: Evaluating the long-term sustainability of the District's existing
groundwater supply

. Task 4: Developing a long-term supply plan

The District is also planning on joining other entities in the South Metro area to
conduct a rain harvest study. This study will be evaluating water rights implications
if the study area collects rainwater for reuse. The collection of rainwater will reduce
the amount of runoff entering nearby streams, reducing the amount of water
downstream for other users. This study will focus on quantifying the amount of water
needed to compensate downstream users.

2.6 Current Water Conservation Activities

In 2003, the District began to implement a variety of conservation measures to
conserve water. These consist of adjusting water rates, watering restrictions, rebate
incentives, and public education. Table 2-10 provides details on each conservation
measure. Further details on water restrictions and the water rate structure are
provided in Sections 2.5 and 2.4, respectively.

Table 2-10 shows that the water savings from the majority of the conservation
activities are difficult to quantify. This is attributed to a variety of factors. For
instance, information on the unit savings for many of the retrofits is limited and the
savings also depends on behavior. Savings through education is highly variable and
depends on a variety of factors including the number of participants and regional
climatic factors. Customers are much more willing to respond to education if there is
an existing water shortage. Section 2.1 describes the per capita demand reductions
since the onset of the programs and provides further explanation on why limited
quantitative data is available on water savings.
