GLEN COVE WATER & WASTEWATER NEEDS
A Summary of the Approach and Assumptions Used
Introduction
The purpose of the water and wastewater infrastructure analysis which follows is to assist the Joint Growth Management Committee in identifying a "preferred "growth alternative for the Glen Cove Special Study Area. The analysis provides estimates of the demand created and the cost to supply water and wastewater services to the two expanded UGA alternatives for Glen Cove (i.e.. Alternative #2 - "Community Serving UGA", and Alternative #3 - "County-wide/Regional Retail & Manufacturing UGA"). The estimates are for general planning rather than engineering purposes. Nevertheless, the analysis provides a credible range of estimated needs and costs upon which to base long range planning decisions.
Water
Determining Water Needs
Water needs for the two expanded UGA alternatives were calculated for each of the different land use designations anticipated (i.e., single family and multi-family residential, community serving commercial, regional commercial, and light manufacturing and commercial). A summary of projected water needs is found on the tables labeled "Water Demand Analysis." The approach and assumptions for this analysis were as follows:
1. Determine the approximate amount of land available for each land use category (for example, 57 acres for Regional Commercial development under Alternative #3). From this figure, subtract 30% for roads and rights of way.
2. Apply reasonable minimum and maximum densities for each residential designation (for example, a minimum of 4 and a maximum of 8 units per acre for single family residential areas).
3. Assume that 800 gallons per day/per connection will be needed for each residence (this is the figure used by the State Department of Health for maximum daily use).
4. Use actual City of Pon Townsend water use data to determine water needs for areas designated for Community Commercial and Light Manufacturing/Commercial development (see the "Water Demand Analysis" and "Water Use Estimates" tables). Multiply the average daily use figure by 3 to estimate maximum daily use.
5. Use actual City of Sequim water use data to determine water needs for areas designated for Regional Commercial development (no regional retail development currently exists in our area). Again, multiply the average daily use figure by 3 to estimate maximum daily use.
Determining Water Infrastructure Needs
The cost estimates for providing water system infrastructure are detailed on the tables labeled "Water System Infrastructure" for each of the expanded UGA alternatives. The estimated costs have also been detailed for each separate land use category. The approach and assumptions used for this analysis were as follows:
1. Estimate water storage requirements based on State Department of Health requirements. To determine the water storage requirements for commercial, manufacturing and residential land use designations, assume that 3,450 gallons per minute for 4 hours would be needed for fire flow (bydrologic modeling suggests that this is the amount available with an upgraded infrastructure). To further clarify the requirements for residential water storage assume reasonable minimum and maximum densities for residential designations (for example, a minimum of 4 and a maximum of 8 units an acre for single family residential areas).
2. Next, estimate the water infrastructure costs for:
a. Supply and treatment (use average daily demand);
b. Storage (use the approach outlined in ffl, above);
c. Installing a new 16" diameter transmission pipeline (costs to be borne by commercial and manufacturing development);
d. Installing new 8" diameter distribution pipelines (calculated using an average spacing of 500' for commercial and manufacturing areas, and 300' for residential areas); and
e. Installing new fire hydrants (calculated using an average spacing of 300* for commercial and manufacturing areas, and 500' for residential areas).
Costs estimates for this infrastructure were based on information for the same facilities contained in Port Townsend's draft Capital Facilities Plan, with a 25% markup for engineering, design, legal, and administrative costs.
3. Finally, the cost per connection was determined by dividing the total cost for each land use category by the estimated number of units at build-out for each land use category.
Wastewater
Determining Wastewater Infrastructure Needs
The cost estimates for providing wastewater system infrastructure are detailed on the tables labeled "Wastewater System Infrastructure" for each of the expanded UGA alternatives. The estimated costs have also been detailed for each separate land use category. The approach and assumptions used for this analysis were as follows:
1. Determine the population to be served by multiplying the estimated number of residential units (both minimum and maximum) by 2.16 (the average household size figure used for the Tri-Area Water System Plan).
2. Calculate the amount of wastewater generated per person by using the recommended level of service from Port Townsend's draft Capital Facilities Plan (i.e., 120 gallons per day per person).
3. Calculate the amount of wastewater generated by commercial and manufacturing areas assuming that all water usage goes to wastewater.
4. Determine the costs for three separate options:
a. Use of the Port Townsend Paper Mill outfall to dispose of treated wastewater;
b. Pumping treated water across the Quimper Peninsula to a new outfall near Port Townsend's existing outfall; or
c. Reuse of the treated wastewater.
5. Calculate the costs for a new treatment plant, 20" trunk line, and 8" collection pipe based on the per unit costs contained within Port Townsend's draft Capital Facilities Plan (split the cost of the new trunk line equally between residential and commercial and manufacturing development; assume that the length of collection line is equal to the length of the water distribution line).
6. For the option which assumes that the treated water will be pumped to the City's existing outfall, add the costs for a new transmission pipe, a new pump station, and a new outfall pipe.
7. For the option which assumes that the treated wastewater will be reused, add an additional per unit cost per gallon per day to cover the costs of additional treatment and storage.
8. Finally, add a 25% markup for engineering, design, legal, and administrative costs.
