CENTRAL KITSAP COUNTY WASTEWATER FACILITY PLAN ...

1: Introduction Central Kitsap County Wastewater Facility Plan
1.2 General Planning Area Definition
A vicinity map showing the general Central Kitsap planning area is provided in Figure 1-1. The planning area
is narrowed in scope as physical, regulatory, and jurisdictional considerations are taken into account; this is
described in Chapter 2. This modified area becomes the study area for which specific recommendations are
made.
1.3 Description of Scope of Work
This Facility Plan presents a through analysis of the factors that affect the selection of project alternatives
over a 20-year period (2005–2025):
• planning area characteristics and population projections
• estimated wastewater flows and loadings
• condition of existing wastewater infrastructure
• current regulations
Based on these factors, a methodology is established by which capital projects for wastewater collection,
treatment, and reuse are identified, evaluated against relevant criteria, and ranked. The key criteria that most
heavily influence the selection of future projects for further consideration are shown in Table 1-1. By
systematically screening all project alternatives against these criteria, the field of alternatives is narrowed and
the optimal combination of technologies emerges. Resultant project recommendations are provided—both
with and without reuse alternatives—and cost estimates are provided.
