Our team of NYC new construction plumbing contractors has performed house sewer, water main, and sprinkler main installations for over 100 years. We understand the importance of working on a deadline to keep your construction schedule moving forward. When you bring your project to us, you are assigned a dedicated team within our office. The team is led by the Vice President of New Construction, who will oversee each project to ensure all work is completed to industry standards.
Instead of wondering how to find out if a plumber is licensed, work with Harris Water Main and Sewer—a family-owned, licensed contractor with over 10 decades of experience. You can trust our new home and building plumbing contractors to handle all your subsurface water main, sewer main or site drainage needs—from a single-family renovation to ground-up superstructure. It requires expertise and experience to stay ahead of the constant updates to the rules and regulations set by DEP, DOB, and DOT. Our NYC new construction plumbing contractors work diligently with all associated agencies to stay ahead of the curve while delivering stellar service from estimation to restoration. Your assigned team will also work on obtaining NYC DEP sign-offs upon completion of the required water main and inspections.
Sewer Installation & SD1&2
If your project proposes a new sewer, DEP will require an SD1&2 which your engineer will create and file for approval. This application will advise on the size, type, and connection for the proposed sewer. In addition to the new sewer main, it will note if a storm water detention or retention system is required. Depending on what the application proposes, different regulations will apply in order to obtain permits. Your project coordinator will walk you through this process to expedite permit approval.
DEP Cross Connection
Depending on your project, a new proposed water main may require the installation of an rpz & meter. If so, your engineer will need to create and file a DEP Cross Connection Letter (Backflow Prevention Letter). This application will advise on the size and type of service to be installed. In addition, it will note the size and type of rpz and meter to be installed. This approval will be required to obtain permits whether you have a ground-up project, renovation or DEP is requiring the installation of an rpz.
Installation of Sewer & Water Main
The installation process will begin with the installation of the proposed sewer (if proposed). The roadway, sidewalk, and property (if applicable) will be excavated in preparation to install the sewer pipe in accordance to the SD1&2. Upon piping, DEP & DOB will inspect the new service.
When the inspection is completed the excavations will be backfilled and restored unless a new water service is proposed. If your project calls for a new domestic, fire sprinkler or combined water service, the excavations will be backfilled to the water main invert in preparation for the tap or wet connection.
After the new connection is installed, the remainder of the pipe will be installed and inspected by DEP. Upon completion of the inspection, the excavations will be backfilled and restored. It’s important to note that these installations should only be performed by highly trained individuals. All the crew at our new construction plumbing company hold the expertise and experience to get your job done. Most importantly, our team will complete the job safely. All Harris employees are trained per the most recent codes associated with DEP, DOB, DOT and OSHA regulations.
Catch Basins, Manholes & Trench Drains
Harris has a specialized team that is highly trained in estimating and installing any of your storm water detention and or retention needs per DOB approved plan.
The new construction plumbing contractors at Harris can handle all of your sewer, water main, and site work estimation your project calls for. Understanding DEP, DOB & DOT requirements allow us to deliver a highly efficient estimate that you can count on for your budgeting purposes.
We have availed the services of Harris Water Main and Sewer Contractors in the past and had no complaints with them. When my husband decided to get a DEP approval to relocate our hydrant due to a new driveway and Harris was awesome! A few other companies didn’t even know what to do and said that it was not possible. Thank you to Jessica in the office and Lee K the engineer for getting this done!read more

We can't thank them enough for saving our day! We needed to have our sewer line replaced, and we did not know how to get started on the project.

They got started quickly and completed the job for us in a timely manner. We would have never been able to get my main sewer line replaced without the help of these guys.

Very happy with their services. I called Harris plumbing who is their sister company, who then notified me that they do not dig and repair sewers. Harris Water came out, reviewed the layout of my house before issuing a formal price. The crew came out for work and was absolutely delighted with the professional service that we received. They were on time, competent, and their prices were very competitive. Highly recommend them.read more

I can’t praise Harris Water Main and Sewer Contractors Inc. enough. From the opening estimate with Elvis to the completion of a sewer line put in correctly, their work was outstanding! They worked hard and precisely to save a precious tree that survived generations, and was almost in line with the sewer pipe. Even though the crew was tired they made the effort to put back hedges and bushes to their original place on my yard. Days later, they replaced the cement sidewalk beautifully! Elvis responded promptly to our pleas of urgency right away. We had a backed up sewer line and knew that it needed to be replaced immediately because we had raw sewage surging from the pipe. We had received 2 other quotes and Harris Sewage was the most reasonable. Elvis was very fair, honest and knowledgeable. Their competitors in comparison were dishonest and scammers, trying to pad the bill with unnecessary extras such as, tree removals, a new sewer trap, and additional pipe replacements that were totally unnecessary. A few days later a crew arrived at 8:00 am and worked tirelessly, digging a 25-foot long trench that was 10 feet deep and 5 feet wide. They found that the ceramic pipe was broken and raw sewage was leaking into the ground! They braced the dirt with wood and replaced the pipe in a day and a half! Danny was an outstanding superman who and worked tirelessly from 8:00-5:00 even in the pouring rain! They were honest workers and did their job well and with integrity even when I wasn’t supervising them! I am so grateful for these guys and Elvis and would personally recommend them whole-heartedly!read more

As COVID-19 cases were hitting peak levels in NYC in April, my building’s sewer line collapsed. Sheltering in place with total septic failure is not a fun place to be. Not able to travel to friends or family and with no public alternative available given the lockdown, things were ripe and uncomfortable for my family and the other people living in the building. Harris Water Main and Sewer to the rescue! Soup-to-nuts, these guys got the job done (the soup was nasty). These guys pulled emergency permits and got to work immediately. They worked into the night to get my job done in three days. They worked professionally and safely. These guys really know their stuff. This was no small undertaking and they aced it. I also shopped their quote and they were right in line with the competition. After seeing their work product firsthand, I would use them again in a heartbeat. I hope I never have to!read more

Thankful to have found a professional and honest company! I received A violation from DEP for my broken pipe and frantically searched for a few companies. Two companies gave me a very expensive price. Elvis from Harris gave me a very fair price but also mentioned that he didn’t think it was my pipe that was broken. As he suggested I called DEP to review again and indeed they agreed! I can’t thank Elvis and the entire team for being honest and professional! Note- I had the DEP insurance and like many others they denied the claim with no true explanation. I have since cancelled my policy!read more

Harris stepped up when our basement was a sewage flood zone a few days before Christmas and got two big jobs done on time and on budget. Both the inside and outside sewer pipe jobs had frustrations along the way for Lyndon, Stanley and their guys (late inspectors, etc) but both crews were friendly, helpful, respectful of our property, and flexible with our requests. It is not luck, I know, but focus, judgement and energy that builds good teams like yours.read more

Harris Water Main & Sewer was amazing!I worked with Elvis and his crew. They were absolutely professional. Initially, I thought my plumbing problem was a burst, leaking external sewer pipe from my basement to underneath the sidewalk, and that 8 feet of the sewer pipe had to be replaced. The Harris team dug approx. 8-10 feet deep into the sidewalk and quickly saw that all the external sewer pipes connected to the main city spur were burst and had to be replaced (over 15 feet). They went above and beyond and replaced all 15 feet with new pipes.They got the job done swiftly and professionally. No time was wasted - the crew was courteous and did their job well. They placed in new sewer pipes, filled in the sidewalk hole and placed in new cement for the sidewalk at the end. It was a great experience working with Harris.Tony C.Queens, NYread more

I received a 3 day notice on Thursday and honestly had no clue what to do, I was in a panic. I found Harris Water and happy I did so, they were extremely professional, their price was lower than all of the other quotes I received and Elvis who made the site visit was excellent to work with. The water main was installed the very next day and DEP was off my back! I was also made aware that they were in business for more than 100 years which made me feel very comfortable.Thank you to Harris for the quick and professional work!read more

This is the best company in every single aspect, if you have to deal with replacing you pipes due to low pressure or no water cases. The crew is amazing, the office is on top of things and you will probably get the best price compared to all those companies you are researching, dealing with this issue. I would like to thank Harris for their professionalism and incredible job they have done! 5+++ STARS easily!read more

Thankful for the reference to Harris from Ajax plumbing after 3 plumbers and one other water main company I was grateful for a professional assessment and estimate of the job. The job ended up being two days rather than one which did not matter as I was so happy to have a major sewer issue fixed. While I hope during my lifetime to never have to deal with a break in the sewer line again if the stars are not in my favor and it happens again I know who to call on.read more

I wanted to take the time to write this review for Harris Water main. I appreciate them resolving my water main and fire sprinkler issue after a frigid winter. They were able to complete the work efficiently and I trusted the workers inside and out of my house.I appreciate the most that they were able to work with me financially and understood the crisis my issue was giving me. The management was great in that aspect and the phenomenal ladies in the office were extremely personable and a true breath of fresh air every time I walked in the office. I would recommend them to anyone in need and hopefully I won't need them anytime soon but I would 100% use their services again. Appreciate you all and keep up the great work!read more

Recently became aware of a sinkhole in front of my house and determined that my sewer line was broken. I reviewed and met with a few companies to gain a better understanding of what was needed. I am happy to have met Mike Kayne from Harris. He was patient with all of my questions, didn't try and force me into a quick decision like others. And most of all he actually gave me a cost effective option to repair a section of my pipe which nobody else did. After further explaining the risk with this I decided to replace the entire sewer line but did feel a level of comfort just for the fact that Mike gave me the option. He also advised on all variables to take place during the installation process. One week later my new sewer is installed and running well!Thank you to Mike, Millie and the entire staff for handling my situation like professionals.read more

Recently used Harris Sewer after my insurance company denied a claim for my broken sewer. They claimed the pipe was back pitched and not covered under warranty. I received several estimates from private firms who were all trying to either sell me an entire new sewer or trying to charge me an exorbitant amount of money.Finally I was referred to Harris who advised that they could repair just a section of the pipe if we were able to identify where the back pitch was located which was later provided by the insurance company.Long story short, the work was completed with a DEP inspection and all in one day. Thank you Harris Sewer!read more

I was on the brink of disaster two days ago when my water main cracked and water was leaking back into my house. I called Harris who calmly walked me through the process to completing the work and even better, had the worked completed the very same day. I really want to thank the entire staff for being so professional when I may have been excited and keeping composure. Thank you!!read more

Before I moved into my house in Brooklyn 5 years ago, the inspector advised me to replace the sewer and water lines going from the street to the house. (At that time, it still had the original lead water pipe from 1902, when the house was built!) I'm so glad that someone referred me to Harris. They did a most excellent, totally professional job. This is not one of those fly-by-night companies (so prevalent in Brooklyn) that are more intent on avoiding paying their business taxes than on doing a good job. It was amazing to see, but this company does this every day and they really know their stuff! I recommend them without reservation.read more

We had a broken sewer pipe. From the very beginning they were very professional. They came out and gave us a quote. They called to schedule a day for the job. They showed up on time and got the job done. They came back at a later date and repaved the road in front of our house. I was impressed when they followed up with a thank you for service and a copy of our full paid invoice. I did not expect this type of treatment. Usually after the job is done the consumer usually hears nothing from the business. Overall, I am satisfied with the job. I only pray that where they replaced will not have any future problems.read more

These guys were on point and worked on my property super quick. I had a main pipe coming from the street going into the property break down on a HOLIDAY 3 DAY WEEKEND.

If I ever need help again, I'll be reaching out to them for sure.read more

I received a 3 day notice from DEP and contacted Harris Water Main. They were recommended by a close friend that works with the city.

I was fairly upset when I got a 3-day notice from the city about my leaking water main, in fact i really didn't know what to do. I called my regular plumbers, but they said they weren't equipped to do this job. Thankfully they referred me to Harris. We quickly got an appointment scheduled for them to come out and take a look. Once I got the estimate and paid the deposit, they took over, getting all permits and applications, handling the 3-day notice, etc. I didn't need to lift another finger. The job itself was big and messy and loud, but I don't think there's any other way to repair something buried in the sidewalk and your driveway. I was impressed with their speed and efficiency. They got here first thing in the morning and the primary job was done before close of business. Two other crews came by in the following days to do the final repair on the road and my driveway. In all, getting the notice was super stressful and no one likes to pay a bunch of money out of the blue, but given that there was no way out except to fix it, Harris gave me a ton of peace of mind and took the job completely off my plate. I would definitely use them again.read more

When I got a three day notice from the city, I knew that I needed to find someone who could come ASAP to fix the issue or else the water would be shut off. I turned to Harris water main and Sewer contractors for help. They came within a few days to assess the site and the problem and sent a team to come fix it pretty soon. They finished the job pretty quickly and cleaned up any residue from the work and made it look just like before the construction took place. I am really grateful for Harris to be able to come as soon as they did and in doing such a great job.read more

The week before Christmas my neighbor informed me that he believed my sewer line was leaking into his basement. This was confirmed and I had three companies come out and give me quotes. I was the fourth house on our Clinton Hill block to do this work and I'm the only one who was thrilled by the company that I hired (one house on the block is still waiting on the repairs to the section of the street that was opened which gets performed after the final payment which is due when work is done). This crew worked incredibly long hours and was completely professional. I would highly recommend them to anyone. The proposal was actually a bit lower than the others I received and there was very little cleanup required in my basement (i had expected a total disaster). They were very clear about how the process would go along and answered all my questions.read more
