This is a set of technical drawings for the Merimere Dike Seepage Control project located in Meriden, Connecticut, prepared by AECOM for the Meriden Water Division. The project involves subsurface pressure injection grouting to control seepage at the Merimere Dike on Reservoir Road. The drawings include a site plan showing boring locations, existing infrastructure including water tanks, pipes, core walls, and monitoring wells, along with cross-sectional views of the dike structure. The grouting plan specifies three lines of curtain grouting on the reservoir side of the concrete core wall, with primary holes spaced at 10-foot intervals that may be supplemented by secondary holes at 5-foot intervals and tertiary holes as needed, based on water injection testing results and observed seepage reduction. Site preparation includes clearing existing trees and brush, removing and resetting bituminous pavement along Reservoir Road to expose the core wall and subbase, and restoring the site upon completion. The drawings establish soil classification systems, boring designations with standard penetration test values, rock quality designation measurements, and recovery percentages for subsurface characterization.

The construction specifications require compliance with the 2002 Connecticut Guidelines for Soil Erosion and Sedimentation Control, with all erosion control measures implemented prior to work commencement and maintained until disturbed areas are permanently stabilized. Contractors must provide interim sedimentation and erosion control measures at active work zones, protect material stockpiles with silt fencing and hay bales, inspect control measures weekly and within 24 hours of precipitation events of 0.5 inches or greater, and monitor for dust and airborne contaminants. Construction activities are restricted 100 feet from wetlands, watercourses, and water bodies for refueling operations, and dewatering discharge directly to drainage systems or water bodies is prohibited. The project will be funded by the Environmental Protection Agency with Davis-Bacon prevailing wage requirements applicable to the work. AECOM served as the consulting engineer on the design, with project registration and subconsultants identified in the drawing documentation dated April 2026.
