East Lyme — Engineers working on a wastewater facilities plan for Saunders Point are slated to update the Water and Sewer Commission about the ongoing study during a special meeting on Thursday.

The meeting, scheduled for 6 p.m. Thursday at Town Hall, will serve as an update on the study, which is in progress and has not yet been completed. The meeting also will include public participation and general discussion, according to the agenda.

The preliminary engineering study by Weston & Sampson is looking at the feasibility of sewers in Saunders Point, the best types of sewers for the area, what would be eligible for state Department of Energy and Environmental Protection standards and estimated costs, said First Selectman Mark Nickerson, the commission's chairman.

It includes studies of topography, bedrock and soils to determine how to best go forward, he said.

The draft facilities plan is expected to be completed by the end of September, according to Brad Kargl, the town's municipal utility engineer.

The plan will then be submitted to DEEP for review and approval, Kargl said.

A public hearing to present the final plan would be held in early December.
