Connecting a Building Sewer to the District Sewer

The Walworth County Metropolitan Sewerage District’s (WalCoMet) wastewater collection system and water reclamation facility require significant investment to ensure they can safely, efficiently, and reliably move and reclaim wastewater. These costs are recovered over time through connection charges as new properties are served by sanitary sewers.

Applications and instructions for a building sewer connection can be found under the Forms and Guidelines section. Additional connection information and definitions can be found in Section 502.2 of the Sewer Use Ordinance No. 82-001.

Connections to the community sewer shall be made to the Municipality in which the connection is being made.

A CUSTOMER UNIT shall mean a unit intended for single-family dwelling purposes. A customer unit shall be defined as a single-family residence, an apartment, a residential condominium unit, or a            manufactured home. For purposes of determining the number of equivalent customer units in the District for non-residential uses, the following ratios are listed below.

Non-residential uses are defined as Commercial, Institutional, and Industrial uses, including but not limited to nursing homes, assisted living complexes, travel trailer parks, hospitals, hotels, motels, and other similar uses. The term “mixed use” is defined as a combination of residential and non-residential uses.

In the event that a parcel is the subject of a “mixed use”, the customer unit count for that customer shall be calculated as:

A + B = C

A = the total number of customer units for the residential units

B = the total equivalent customer units (determined by meter size) for the non-residential units

If “B” is a negative number, it should be considered as zero in the formula.

C = the total number of customer units

Where a customer does not have a water meter(s) for measuring the customer’s water consumption, the Administrator shall estimate the number and size of water meters that would otherwise be required to serve the parcel, based on standard engineering practices; and the customer units shall then be determined on this estimate. Customer units shall be determined for each new customer or for  existing customers that may modify the existing meter size.
