Danbury Treatment Plant Connection
Danbury
The Danbury takes the Brookfield wastewater discharge under what is called an Interlocal agreement. That agreement requires Brookfield sewer system users to pay per gallon for operations, plus pay an apportioned amount for plant improvements. In the later part of the decade 2005-2011, Brookfield has used about 2.5 percent of the total flows handled by the plant. Consequently, Brookfield users pay 2.5% of the improvements to the Danbury Publicly Owned Treatment Works (POTW).
By the Interlocal agreement, Brookfield is limited to discharge an average of 500,000 (500M) gallons per day. About half that purchased plant capacity is used as of the second half of the "20 ought" decade. See the chart of historical discharges below.

Q & A:
Q: What is the system capacity?
A: The instantanous flow rate of the pumps to Danbury is 2000M Gallons per day. The practical capacity is roughly 50% of that or 1000M, that is, a million gallons per day.
Q: Can Brookfield send that quantity to Danbury for treatment?
A: No. The InterLocal agreement with Danbury limits flow to 500M gallons per day on the average.
Q: With projects currently on the drawing board what is the danger of running out of capacity?
No. There is sufficient capacity for the first half of this decade with the current Danbury agreement and the current capability of the equipment. The Danbury agreement is due to be re-negotiated in 2012.
Projects in play include:
| Development: | Units | GPD | Status |
| Barnbeck Condos | 150 | 16 | (Under construction) |
| Industrial Units Federal Road | 25 | 6 | (Under construction) |
| Newbury Village | 120 | 7 | (Half Completed) |
| Oakridge Condos | 80 | 9 | (Under construction) |
| Old New Milford Road | 23 | 10 | (Under construction) |
| Riverview Condos | 60 | 7 | (Under construction) |
| Sandy Lane | 80 | 0 | Re-routing system to gravity |
| Possible Future: | |||
| Dean Road | 80 | 8 | Under Discussion |
| Lake Areas | 450 | 50 | Nothing is planned |
| Whisconier Areas | 250 | 27 | Nothing is planned |
| "Cornfield" property | N/A | < 20 | for whatever may be built |
| Others-Long Range | N/A | 160 | for whatever may be built |
| Total | < 300 | ||
Note: These planned and future totals should not exceed the capability of the equipment. A review of the infrastructure will be conducted after the expanded monitoring system is installed. Separately, a study is under way to determine if additional capacity from Danbury will need to be increased from the 500,000 gallon per day limit.
