Title

Ponto Sewer Manhole Rehabilitation Project

Description

The City of Carlsbad (city) proposes to clean and rehabilitate nine sewer manholes, which are approximately 50 years old and are experiencing significant corrosion, spaced at approximately 400-foot intervals along the North Ponto Sewer, a 27-inch-diameter vitrified clay pipe gravity sewer pipeline. Within the 11.71-acre Project site, the area of direct impact, consisting of nine manholes and access areas, covers a total area of 0.13 acres.To address potential leaks and structural failure, the proposed Project involves pressure washing the interior of the manholes; repairing internal cracks and wall surfaces; installing liners inside the manholes; and minimal external work, including the replacement of all manhole frames and covers, replacement of 5-foot-square concrete pads at four of the manhole locations, and new installation of the concrete pads at the other five manhole locations that currently do not have pads.
