 STATE OF NEW YORK

 1175

 2025-2026 Regular Sessions

 IN SENATE

 January 8, 2025
 ___________

 Introduced by Sen. MATTERA -- read twice and ordered printed, and when
 printed to be committed to the Committee on Environmental Conservation

 AN ACT to amend the environmental conservation law, in relation to rain-
 water harvesting

 The People of the State of New York, represented in Senate and Assem-
 bly, do enact as follows:

 1 Section 1. Article 15 of the environmental conservation law is amended
 2 by adding a new title 35 to read as follows:
 3 TITLE 35
 4 RAINWATER HARVESTING
 5 Section 15-3501. Purpose.
 6 15-3503. Rainwater harvesting feasibility.
 7 15-3505. Rainwater harvesting conveyance.
 8 15-3507. Rainwater harvesting pretreatment.
 9 15-3509. Rainwater harvesting treatment.
 10 15-3511. Rainwater harvesting landscaping and vegetation.
 11 15-3513. Rules and regulations.
 12 § 15-3501. Purpose.
 13 Rainwater harvesting practices, when designed to temporarily store
 14 stormwater runoff for detention or re-use through retention, may assist
 15 in meeting stormwater runoff reduction goals.
 16 Rainwater harvesting is the capture, conveyance, and storage of
 17 precipitation from impervious surfaces, typically rooftops, primarily
 18 for re-use, rather than infiltration or release into a waterway. Rainwa-
 19 ter harvesting has minimal site requirements compared to other stormwa-
 20 ter management practices and may be used in residential and industrial
 21 settings for any volume of rooftop runoff, if sized appropriately.
 22 Rainwater harvesting may be used on sites where dense development,
 23 pollutant hotspots, or soil conditions preclude the use of infiltration
 24 or other stormwater management practices. The use of rainwater harvest-
 25 ing reduces the amount of stormwater runoff entering the drainage system

 1 and local receiving waters as well as reducing or delaying peak flow
 2 rates. It is important to have well-defined operation and maintenance
 3 procedures for any rainwater harvesting system, in order to provide
 4 adequate storage capacity for subsequent storm events.
 5 Storage tanks for harvested rainwater may be sited above- or below-
 6 ground, indoors or outdoors, or on rooftops of buildings that have been
 7 designed to bear the load of rainwater storage. The main components of a
 8 rainwater harvesting system include: a contributing rooftop surface; a
 9 conveyance system of gutters, downspouts, and pipes; screening or pre-
 10 treatment filter and clean-out; a watertight storage container; an over-
 11 flow pipe; an access hatch; and an extraction system, such as a spout or
 12 pump. Additional components may include a first flush diverter, pres-
 13 sure tank, and backflow prevention device.
 14 Rain barrels are commonly used to store harvested rainwater in small-
 15 scale residential settings, while above- or below-ground cisterns are
 16 more commonly used in larger-scale industrial settings. Rain barrels are
 17 above ground storage tanks generally holding fifty to eighty gallons,
 18 but may hold up to two hundred gallons. Cisterns are sealed tanks, which
 19 may be above or below ground and generally hold two hundred to ten thou-
 20 sand gallons. While carefully managed rain barrels can be a viable means
 21 of stormwater runoff volume reduction for very small volumes of rainwa-
 22 ter, this standard is intended to be appli
