Current Status
Nighttime construction continues [3:30 PM - 6:00 AM] to finalize sewer installation, with crews having worked overnight since early 2025. Final road paving began in March 2025 and is expected to wrap by late June 2025. Sewer line connections to properties are ongoing, with completion anticipated by July 2025, weather permitting.
Next Steps
As of April 2025:
Finish Paving and Road Restoration
Crews are completing paving and restoring all impacted roads with new asphalt and painted traffic lines by mid-May.Sewer Hookups Begin
After paving is done, eligible properties will begin connecting to the sewer system—helping homes and businesses get off old cesspools.Ongoing Outreach
Suffolk County Public Works continues to talk with local businesses and property owners to answer questions and help prepare for sewer hook-up.
Project Timeline
Construction start: Summer 2023.
Road repaving milestone: Finished by May 2025
Expected sewer completion: Late 2025, per Suffolk County’s strategic plan for the Downtown Revitalization Initiative (Previously noted as late 2025–early 2026.)

Purpose
Economic Development
More business opportunities: Restaurants, cafés, and bars can now open or expand without septic limitations.
Mixed-use development: Enables apartments above shops and revitalized storefronts.
New investment: Previously unusable properties are now viable.
Attracts new businesses: Makes vacant/commercial spaces usable again.
Property Value
Homes and commercial buildings connected to sewers usually gain value and flexibility.
Environmental Protection
Reduces nitrogen pollution and contaminants from old septic systems.
Helps protect local groundwater and surface waters (like the Nissequogue River).
Supports the Suffolk County Subwatersheds Wastewater Plan.
Public Health & Safety
Reduces septic system failures that risk drinking water.
Ensures wastewater is treated safely through a regional system.
Flood Protection
Sewer system upgrades reduce flooding risks during storms.
Downtown Revitalization
A key piece of the Kings Park Downtown Revitalization Initiative (DRI).
Creates a more walkable, vibrant Main Street near the LIRR.
Supports transit-oriented development (TOD).
Concerns:
Construction Disruption
Night work (8:30 PM–6:00 AM) along Main Street and Indian Head Road caused detours and business access issues.
Concerns about road restoration quality and disruption to traffic and walkability.
Costs & Long-Term Fees
An extra $5.4 million was approved in 2023 due to inflation and materials.
Homeowners may pay an estimated $548/year, businesses around $1,507/year.
Seniors and fixed-income residents have raised concerns about affordability.
Post-construction fees and taxes are still a topic of discussion.
Timeline Concerns
Past delays from state and county funding processes have caused frustration.
While sewer work is nearing completion (as of Spring 2025), some residents remain skeptical about remaining project timelines.
Overdevelopment Pressure
Sewer access makes development easier—raising concerns about overdevelopment and potential changes to Kings Park’s small-town feel.
Questions remain about whether sewer lines will expand into nearby residential neighborhoods.
While there are no costs to property owners for the initial installation of sewer mains or the lateral connection from the street to the property line, property owners will pay annual sewer usage fees once connected.
The County sets the fee structure, and like other utilities, rates may change over time.
Property owners are responsible for any plumbing work needed inside their building to connect to the new sewer system.

Frequently Asked Questions
Why is the sewer project happening?
Downtown Kings Park has never had a public sewer system. Businesses have been stuck with old cesspools, which limits what they can do. This project brings the infrastructure we need to grow, attract new shops and restaurants, and protect our environment.
Will I need to connect to the new sewer system?
If your property is included in the service area, you’ll be contacted with specific instructions. Most downtown commercial properties will need to connect. Residential properties may have the option, depending on location and setup.
Will this cost me anything?
You won’t pay for the sewer lines or hookup—that’s covered by state and county funding. Once connected, you’ll pay a yearly sewer fee:
Around $548/year for homes
Around $1,507/year for businesses
Final rates will be confirmed before billing begins.
Where does the wastewater go?
Wastewater will be sent to a Suffolk County treatment plant. A 16.7-acre recharge site at the old Kings Park Psychiatric Center will safely return the clean, treated water back into the ground.
Who can I contact if I have questions?
