RE:     The Capacity to Handle Wastewater Flows from 65 Munjoy Street – Eight Unit Residential 

Dear Ethan Boxer-Macomber:
 
The Department of Public Works, which includes the Water Resource Division have reviewed and determined that the downstream sewers from 65 Munjoy Street has the capacity to convey the estimated 1,380 gallons per day (gpd) of proposed wastewater which will be generated from this building.  You are reminded that the sewer you are proposing to connect is combined and therefore a backflow preventer is required.  
 
As you may be aware, any addition of wastewater flows in this drainage area will have an impact on CSO discharge volumes.  However, since you are proposing a rain garden infiltration system, additional wastewater volumes will be offset by reductions in stormwater runoff discharging to the combined sewer system.  This system may be eligible for a stormwater runoff credit.
 
If the City can be of further assistance, please call 874-8850 or 400-6695.                                                                                       
Sincerely,
                                                                                                                                CITY OF PORTLAND
 
                                                                                                                                David Margolis-Pineo

Anticipated Wastewater Flows from Proposed eight Unit Residential:
                Four – One Bedroom Units @ 120 gpd each = 480 gpd
                Two – Two Bedroom Units @ 180 gpd each = 360 gpd
                Two – Three Bedroom Units @ 270 gpd each = 540 gpd
                                                                                                Total:  1,380 gpd
