Rates & Charges

1. Municipal Wastewater Charges (charged to local government units):

The charge to communities for sewer service treatment. All 108 customer communities pay MCES an allocated portion of MCES Municipal Wastewater Charges based on the volume of wastewater treated. Most communities cover their own sewer costs by charging a higher "retail" rate to residents and businesses (these rate "mark-ups" are specific to each city). Questions? Contact MCES Finance by email.

Municipal Wastewater Charges
Time Period 2016 2017
Total MCES Municipal Wastewater Charges $201,013,000 $211,932,000
Total System Flow (July 1 - June 30 flow period) 85.60 BG 85.3 BG

2. Metropolitan Sewer Availability Charge (SAC) (charged to local government units and other communities with building authority):


A one-time fee for new connections or increased capacity demanded of the metropolitan wastewater system. One SAC unit equals 274 gallons of maximum potential daily wastewater flow capacity. Communities are charged one SAC for a single-family residence. Communities pay a prorated SAC fee for all other types of buildings or wastewater demand based on the estimated capacity of wastewater they may demand. Additional information is on the SAC Program website.

Qualified Outdoor Spaces (effec. 10/01/09)     75%
Industrial: Base Unit Fee x Number REUs where the number of REUs is based on the maximum normal flow volume See Base Unit See Base Unit  

3. Industrial Strength Charges (charged directly to industries):

Fees for additional treatment costs caused by industrial wastewater that has more pollutants than typical residential wastewater. Industrial strength charges are based on the concentration of pollutants (as measured by Total Suspended Solids (TSS) and Chemical Oxygen Demand (COD)) and the volume of the discharge. Strength charge rates are set by the Council based on expenses at wastewater treatment plants for treating TSS and COD in excess of normal residential wastewater. Industrial users are also subject to normal municipal wastewater (volume) charges and SAC through their host communities. 

Industrial Strength Charges - Within Council Region
Time Period 2016 2017
Cost per excess pound of Total Suspended Solids (TSS) $0.204 $0.220
Cost per excess pound of Chemical Oxygen Demand (COD) $0.102 $0.110

4. Liquid Waste Hauler Load Charges (charged directly to haulers):

Liquid waste haulers pay MCES for septage, leachate, and other hauled wastes that are discharged to approved MCES disposal sites. The load charge combines a strength charge component, a facilities component and a volume component. The volume component is based on the MCES municipal wastewater rate. In addition, a $15.00 per 1,000 gallons Service Fee applies to hauled wastes originating outside the Region. Load charges are different for holding tank, portable toilet waste, septage, and industrial wastes.

Load Charges (per 1,000 gallons)
Time Period 2016 2017
Standard Load Charge $58.80 $60.24
Holding Tank Rate $9.34 $10.30
Portable Toilet Waste Rate $75.86 $77.46
Collar County Load Charge (includes $15.00 per 1,000 gallons service fee for waste from outside the region) $73.80 $75.24

5. Industrial Discharge Permit Fees (charged directly to industries):

Industrial Users of the system must apply for a permit from MCES to discharge wastewater. Those Industrial Users issued a permit are subject to annual permit fees, which recover a portion of the costs to administer the industrial pretreatment program. Permit fees are based on permit type, annual volume of wastewater, Significant Industrial User (SIU) status, and reporting frequency.

2016 Industrial Discharge Permit Fees
Volume (MGY) >50 m. <50 m. >10 m. 5-10 m. 2-5 m. <2 m. >1 m. <1 m.
Quarterly Reporters $9,325 $7,800            
Semi-annual Reporters     $6,175 $4,675 $3,075 $1,575    
Annual Reporters & Liquid Waste Haulers             $1,575 $975
General Permits $100-$500              

6. Industrial Waste Temporary Capacity Charge

Assessed for temporary use of the Metropolitan System (e.g. disposal of treated contaminated groundwater). Charge is assessed in lieu of SAC due to the temporary nature of a service - essentially renting capacity in the system.

  • Charges (per 1,000 gallons) for 2016 are $1.25, those for 2015 were $1.25.

7. Self-monitoring Report Late Fees (charged to industries):

Assessed to permittees who fail to submit a complete self-monitoring report on a timely basis. The late fee amount is based on the frequency and severity of late reports.

Self-Monitoring Report Late Fees
Days Late 1-30 Days 31-60 Days 61-90 Days  Total
1st Late Report $150 $150 $150 $450
2nd Late Report $150 $200 $250 $600
3rd Late Report $150 $250 $300 $700
4th Late Report $150 $300 $350 $800

8. Stipulation Agreement Payment (charged to industries):

Negotiated monthly payments and daily penalties intended to negate the economic advantage of noncompliance with federal pretreatment standards or local limits.

9. Industrial Waste Cost Recovery Fees (charged to responsible/requesting parties):

Used to recover MCES costs from any responsible party associated with spill or enforcement responses, non-routine data requests, special discharge requests, orders to appear, or notice of violations.

10. Inflow/Infiltration Demand Charge (charged to local government units):


The wastewater demand charge will include the cost of wastewater storage facilities and/or other improvements necessary to avoid overloading Council conveyance and treatment facilities, and the appropriate charges for use of capacity beyond the allowable amount of inflow and infiltration for those communities that have not met their inflow and infiltration goal(s), if the community has not been implementing an effective inflow and infiltration reduction program as determined by the Council, or if regulations and/or regulatory permits require Council action to ensure regulatory compliance. More information can be found on the I/I Program web page.

11. Encroachment Application Fee (charged to private parties that propose to encroach):


The fee recovers administrative costs for time spent by MCES staff developing and processing encroachment agreements. It covers the average costs associated with reviewing the application and preparing the agreement. Additional information may be found on the interceptor web pages.

The 2016 and 2017 encroachment application fee is $600.

12. Direct Connection Application Fee (charged to local government units):


This fee, which is billed to the city or township, applies when a request is made to connect directly to an MCES interceptor. It recovers administrative costs for time spent by MCES staff on a connection request (an of average 16 hours is spent permitting, reviewing, modifying, drawing and inspecting). Since about half of MCES staff time spent on a request is done before the actual connection is made, half of the fee will be refunded if MCES does not approve the connection. The Connection Application Form link can be found on the interceptor web page.

The 2016 and 2017 direct connection application fee is $1,000.
