DATE: March 21, 2022 
SUBJECT: Strike everything amendment to H.B. 2619, relating to rainwater harvesting program 
 
Purpose 
Establishes the Rainwater Harvesting Grant Program (Program) and outlines Program 
requirements. Appropriates $1,000,000 from the state General Fund (state GF) to the Arizona 
Department of Water Resources (ADWR) to administer the Program. 
Background 
A rainwater harvesting system (system) captures, diverts and stores rainwater for landscape 
irrigation and other uses. Systems are generally divided into simple systems and complex systems. 
A simple system: 1) immediately distributes rainwater to planted areas; and 2) consists of a 
catchment, a distribution system and a landscape holding area. A complex system: 1) stores some 
or all of the rainwater in a container for later use; and 2) consists of a catchment, conveyance 
systems, storage and a distribution system (City of Tucson). Passive rainwater harvesting includes 
directing and retaining water in the landscape by using site-appropriate practices such as basins, 
berms, terraces, swales and infiltration trenches. Active rainwater harvesting includes a storage 
tank to store water for later use with overflow directed towards a passive retention feature or a 
passive rain garden (City of Tucson). 
The City of Tucson administers the Rainwater Harvesting Incentives Program for single-
family residential and small commercial Tucson water customers. Applicants may apply for 
rebates for both passive and active projects, not exceeding $2,000 per property. Applicants must, 
in order to qualify for the Rainwater Harvesting Incentives Program: 1) attend an approved 
Rainwater Harvesting Incentives Program three-hour workshop; and 2) submit a project plan (City 
of Tucson).  
Statute grants the Director of ADWR general control and supervision of surface water and 
groundwater distribution and appropriation. The Director of ADWR may formulate plans and 
develop programs for the practical and economic development, management, conservation and use 
of surface water, groundwater and watersheds in Arizona, including the management of water 
quantity and quality (A.R.S. ยงยง 45-103 and 45-105). 
The strike-everything amendment to H.B. 2619 appropriates $1,000,000 from the state GF 
to ADWR in FY 2023. 
Provisions 
1. Establishes the Program in ADWR to assist persons in installing passive or active systems to 
collect and retain rainwater on site.

rain storage tank, up to $2,000. 
7. Stipulates that eligible reimbursement costs for a level 1 grant project include those of: 
a) surface, subsurface and conveyance features; 
b) mulch, soil amendments, rocks and boulders for reinforcement; 
c) equipment rental such as tillers, jackhammers and trenchers; 
d) permit costs and costs for curb cuts and coring; and 
e) labor from persons licensed by the registrar of contractors in the specific trade or field
