Plain English Breakdown

The bill does not specify the Department of Health's role in funding dual line systems.

Water Use Rules for New Developments

This bill authorizes the Board of Agriculture to investigate nonpotable water availability, requires new residential and mixed-use developments in designated areas to use dual line water supply systems if permitted by the Commission on Water Resource Management, includes these developments in irrigation projects, and updates rules for relevant departments.

What This Bill Does

  • Authorizes the Board of Agriculture to investigate and survey the availability of nonpotable (not drinkable) water.
  • Requires new residential and mixed-use developments located in designated water management areas to use dual line water supply systems if permitted by the Commission on Water Resource Management.
  • Includes these new developments in irrigation projects, as defined in chapter 167 of Hawaii Revised Statutes.
  • Updates rules for the Department of Health, Board of Agriculture, and counties to allow dual line water supply systems in residential and mixed-use developments.

Who It Names or Affects

  • New residential and mixed-use developments
  • The Board of Agriculture
  • Commission on Water Resource Management

Terms To Know

Dual line water supply systems
A system that provides separate lines for potable (drinkable) and nonpotable (not drinkable) water.
Nonpotable water
Water that is not suitable for drinking but can be used for other purposes like irrigation or cleaning.

Limits and Unknowns

  • The bill does not specify how the dual line systems will be funded.
  • It is unclear what happens if nonpotable water is not available in a designated area.
  • The effective date of July 1, 3000 seems to be an error or placeholder.

Amendments

Section 167-5, Hawaii Revised Statutes, is
amended to read as follows:

Powers.
�

In addition to any other powers granted to the board of agriculture for
the purpose of carrying out all of its functions and duties, the board shall
have the following powers for the purposes of this chapter:

����
(1)
�
To acquire by eminent domain, water and
water sources either above or underground, watershed, reservoir sites,
rights-of-way over lands and property for paths, trails, roads, and landing
sites, ditches, tunnels, flumes, reservoirs, and pipelines necessary or proper
for the construction and maintenance of water facilities for conveying,
distributing, and transmitting water for irrigation and domestic use and for [
such
]
other purposes as may properly fall within the scope of its activities in
creating, managing, controlling, operating, and maintaining irrigation water
facilities, any of which purposes shall be held to be for a public use and
purpose;

����
(2)
�
To make and execute contracts and other
instruments necessary or convenient to the exercise of the powers of the board,
including, without prejudice to the generality of the foregoing, contracts and
other instruments for the purchase or sale of water and for the purchase or
lease of water facilities for irrigation of the area, including but not limited
to the production of agricultural products and the land on which the facilities
are situated, and for securing to the owners and occupiers of land already using
water in a project a priority right to so much water from those of their
sources and facilities [
which
]
that
are taken over for the
project as is required for the purposes or needs of the land, whether
agricultural or nonagricultural in nature, as [
such
]
those

purposes or needs exist at the inception of the project or are then
contemplated in the immediate future;

����
(3)
�
To [
make and from time to time
]
adopt,

amend
,
and repeal bylaws and rules, not inconsistent with this chapter,
which upon compliance with chapter 91 shall have the force and effect of law,
to carry into effect the powers and purposes of the board;

����
(4)
�
To make surveys for the purposes of
determining the engineering and economic feasibility of each project;

����
(5)
�
To conduct or have prepared
comprehensive studies of the crops, livestock, and poultry [
which
]
that

may be profitably grown or produced within each project and the probable market
for [
such
]
those

crops, livestock, and poultry;

����
(6)
�
To conduct feasibility studies of the
economic potential of the area;

����
(7)
�
To determine the probable costs and
value of providing water for irrigation in any proposed project;

����
(8)
�
To investigate and make surveys of
water resources, including
the availability of nonpotable water and
the
possibility and feasibility of inducing rain by artificial or other means;
and

����
(9)
�
To define and redefine the boundaries
of projects and to consolidate or separate projects, existing or proposed
pursuant to this chapter[
,
]
;
provided that in the event the
redefinition of the boundaries or the consolidation or separation previously
effected increased the total amount required to be derived from acreage
assessments upon lands within the existing project or projects by more than
five per cent or will require an increase in the tolls charged for water
supplied to the lands or will reduce the amount of water normally available for
distribution to the lands, then the redefinition, consolidation, or separation
may be accomplished only after notice has been published and a public hearing
held as required for the formation of a project upon the initiative of the
board.
�
At the hearing, right to protest
and the procedure relative to protest shall be the same as specified in section
167-17 concerning the formation of projects, and the proposed redefinition of
boundaries, consolidation, or separation of projects shall not be accomplished
if protests, such as would be sufficient to prevent the action if it were the
formation of a project, are filed by owners and lessees of land within the
existing projects or projects affected thereby.

����
The
board is empowered, upon petition of land occupiers as provided by section
167-13, or upon petition of the Hawaiian homes commission or upon its own
initiative, to prepare detailed plans for the acquisition or construction of
facilities for irrigation or for economic development [
which
]
that

in its opinion are economically feasible, to prepare estimates of the probable
cost of each, and to prepare estimates of the water tolls and acreage
assessments required for the cost of operation and the amortization of the
investment of each project, so that the project shall be self-supporting."
