Project Description

Project Overview

Inwood28D&B Engineers and Architects, P.C. (D&B) along with another firm developed a Master Plan for Nassau County’s wastewater treatment facilities. The Nassau County Department of Public Works (NCDPW), owns and operates the Bay Park Sewage Treatment Plant (Bay Park), the Cedar Creek Water Pollution Control Plant (Cedar Creek), and thirty-seven pumping stations. The objective of the Master Plan was to evaluate service area flow projections, future regulatory requirements, facility condition, facility capacity, and facility treatment performance in order to develop and evaluate capital alternatives over a 20 year planning period.

NCDPW---37PumpThe methodologies utilized included conducting an asset condition assessment and evaluating facility performance and capacity for Bay Park, Cedar Creek and thirty-seven pump stations through on-site visits and review of all existing design and operations data. Capacity, regulatory, condition, and performance assessments were then used to identify a number of capital alternatives to be required over the 20-year planning period. The development of capital alternatives to identify planning-level design approaches and capital costs allowed for a draft plan to be completed during workshop sessions with DPW.

A twenty (20) year capital plan was developed which included the major work items to be accomplished at each treatment facility and pump station. Based on the overall assessment completed, which included preliminary cost estimates for each treatment component (five, ten, and twenty year costs), a Capital Master Plan was completed with five year increments for the twenty year planning period.
