DETAILED COST ESTIMATES i.

V. dump station must be paid. This flow can only be accurately determined by metering or keeping records of the use of the dump station. An estimate of this monthly charge based on the assumed use of 2600 gals./day and the current City af Everett sewer rate of $5.10 per month per residential equivalent (900 cubic feet of sewage per month) can be calculated as follows: . Equivalents: � 2600 gals/day x 30 days/mo ; 7.48 gals/cubic ft ;—900 cubic ft/mo./equivalent ' = 11.59 equivalents • Estimated Additional Monthly Charge: $5.10/equivalent/mo. x 11.59 equivalents = 59.11/month This $59.11/month would be in addition to tfie current monthly sewer service charge at the site. Sewer service charges are set by City ordinance and will change over time. To accurately determine the flow equivalents for the use of the R.
