Comments on the Second Draft of Capacity Management Plan
|
| 1st Draft | 2nd Draft | Notes | |
| Baseline Average Flow | 373,500 gpd | 340,000 gpd | The revised figure was suggested by Williams & Connolly pg 5 |
| Remaining Flow | 127,000 gpd | 160,000 gpd | |
| - Flow due to outstanding permits | 30,500 gpd | 12,500 gpd | = 72 units connected since 1st draft |
| = Available Flow | 96,500 gpd | 147,500 gpd | |
| - Wet Weather Reserve | 16,500 gpd (3.3%) | 20,000 gpd (4%) | % of total plant capacity (500,000 gpd) |
| /2 = Available 1st Year | 40,000 gpd | 63,750 gpd | |
| Institutional | 2,000 gpd (5%) | 2,000 gpd (3.1%) | 1,250 already committed for Hospice Facility |
| Commercial/Industrial | 8,000 gpd (20%) | 15,000 gpd (23.5%) | 5,270 already committed first year |
| Residential Infill | 1,000 gpd (2.5%) | 5,500 gpd (8.6%) | |
| Other developments | 3,000 gpd (7.5%) | included as infill above | |
| Northbrook/Symphony Village | 26,000 gpd (65%) | 41,250 gpd (64.7%) |
If the revised flow numbers are to be believed, then this should keep everyone happy.
There are math errors in Sec. ID (Page 4):
For Symphony Village, 329 outstanding units works out to be 82,250 gpd not 80,250. In addition, another 9 units (2250 gpd) should be allocated to the clubhouse since the original allocation was based on 97 units. Thus, the total should work out to be 84,500 gpd.
For Northbrook, 291 outstanding units works out to be 72,750 gpd not 50,000 gpd.
See Sec ID (Page 7): The plan still requires a new allocation even if the change in use results in fewer gpd of use. This does nothing to encourage commercial development that results in lower usage.
I applaud the town for sticking with the 250 gpd/household figure instead of allowing Symphony Village to use a 175 gpd/household figure. See Sec II (page 8).
The plan still does not name who the Controlling Authority and the Approval Authority actually are, Sec IV (Page 12). I would suppose that Miller Environmental is the controlling authority and the Town Manager is the Approval Authority. If that is so, then the plan should say so. However, the Town Council should be the Approval Authority for commercial allocations until a policy, and associated calculations, is established.
I think the I&I Study recommended in the second draft, Sec IV (Page 12) is a waste of money. We have had reduced flow at the plant when 18,000 gpd have been added due to new construction and have had one of the wettest summers in recent years.
Here is the first draft, if you need it.
