Pressure sewer systems
We will support servicing of new single lot residential developments with pressure sewer where it is demonstrated to be the preferred servicing option. This may be for servicing the full development, or part(s) of the development in combination with conventional gravity sewer.
Our policy is to own and maintain the on-lot pressure sewer units where it complies with our standards. Pressure sewer servicing development other than a single residential dwelling (such as in commercial or industrial applications) may be permissible in certain circumstances, however these pressure units will not be owned or maintained by us.
