Council Member Gennaro and Paul Rush discuss the role of the Delaware Aqueduct in New York City's water supply system and the current process of rebalancing water distribution after recent repairs.
- The Delaware system typically provides 50% of NYC's water supply
- Currently, 815 million gallons per day are coming from the Delaware system out of a total demand of nearly 1 billion gallons
- The discussion covers the distribution of water from different systems (Delaware, Catskill, Croton) and the process of rebalancing the system

So we've improved quite a bit.
Jim Gennaro
0:29:07
Yes.
0:29:08
That that we we've been we've been catching up.
0:29:11
I'd like to, recognize council member council member Alexa Aviles, who has joined us.
0:29:17
Always a pleasure to, be with her.
0:29:20
Thank you for joining us.
0:29:23
And and if you have any questions, Alexa, like, now is the time to sign up, because I'm gonna just gonna do a brief little thing and then throw it over to the members and then come back.
0:29:37
And with regard to the Delaware aqueduct, I mean, I obviously, it's something that had to be done.
0:29:45
Let's just talk a little bit about the Delaware aqueduct in terms of the, so we got the Croton system, which in the planning for the for the Delaware fix, we were going to push that system to the maximum, push the caskill to the maximum, do repairs, make sure everything was in good shape.
0:30:06
But on an ordinary day, to the extent there is such a thing as an ordinary day, the percentage of water that's supplied to the city, through the Delaware Aqueduct is a very big number.
0:30:23
Right?
0:30:24
Isn't it it's well over 50% that we normally of of the water we get from the city to the city, it's from the Delaware aqueduct.
0:30:32
So how much of the water that we receive right now in the newly opened Delaware aqueduct is is is is furnishing the water with, city furnishing the city with water?
Paul Rush
0:30:48
So, normal percentages for the city, for this for this system, long term averages, we have 50% of our supply from the Delaware system out of Rondeau reservoir, 40% out of the Catskill system leaving a show can, and about 10% out of the Croton system.
0:31:05
That's the long term averages.
0:31:08
Today, we're moving so the city demand is just under a 1000000000 gallons right now.
0:31:15
Today, we're moving 815,000,000 gallons a day out of Rondeau reservoir from the Delaware system.
0:31:22
So 815 out of almost a 1000000000 gallons a day is coming out of the Delaware system.
0:31:29
So we hadn't used that, the reservoir's in the Delaware, for quite a while, so we have more water in the Delaware system, so we're favoring Delaware.
0:31:38
The Croton system right now, about 75,000,000 gallons a day are going to the system from the Croton system, and out of the Catskill system we're pulling 300.
0:31:50
So that's more than what the city uses every day.
0:31:52
That's because we have storage volume that we're refilling east of Hudson, in Westchester and Putnam Counties with that excess water.
0:32:01
So we're going into the process of rebalancing the system right now, and most of we're back into what we would say is a normal configuration, the way we distribute water into the city.
