Recent Utah Legislation Affecting Wastewater Reuse Water Environment Association of Utah Annual Conference March 30, 2006 Jerry Olds State Engineer
Objectives Basic Principles of Water Law & Reuse New Legislation Example – Water Right Considerations for a Reuse Project
What water uses are covered by a municipal water rights? Domestic, commercial, industrial, irrigation, stockwatering, etc Could water uses change over time? What are the deletion limits for municipal use?
Irrigation Recycling System Can the water user capture and recycle the water? Yes, if 1) it has not left their control; 2) they use the water for the same purposes; & 3) they do not irrigate more land.
Chapter 73-3c - C onservation and Use of Sewage Effluent (1995) Drought of 1999-2004 New sources of water are limited Cost to develop effluent Litigation Proposed Legislation – Water Task Force
HB 38 – Water Reuse Requirements 73-3c – Wastewater Reuse Act Reuse authorization contract Reuse by a public agency Administered as municipal water right Consistent with water right Does not enlarge Return flow satisfied
Water Reuse Requirements (cont’d) Application Requirements Specify required information Reuse authorization contract Project Sponsor Treatment Plant Collection System WR Owner Water Purveyor Sellers of reuse water Retailer - replaced by reuse Agree w/ reuse & pledge is consistent WR
Reuse Application Process Public Notice – Newspaper & Web Protest/Hearing Decision Can deny, if inconsistent Approve with conditions Judicial Review
Other Provisions Annual reporting Rulemaking Infiltration water Change - point of discharge, WQ Board Consultant with state engineer
EXAMPLE: Deer Springs City (Units: Acre-Feet) DivDepl. WR #1 Spring A, 1.0 cfs or 350 af 350350 WR #2 Spring B,.75 cfs (35.0 ac)14070 WR #3 Well A,.50 cfs (30.0 ac)12060 WR #4 Well B, 1.5 cfs (80 ac.)320160 Allowable Diversion930 Acre-Feet Allowable Depletion640 Acre-Feet
Deer Springs City (Cont’d) 40% used in house (20% Depleted) 60% irrigation of lawns (65% Efficiency) Secondary Treatment – Sewage Effluent Discharged to Stream How much of their effluent can they reuse?
Deer Springs City (Cont’d) Current Depletion ((930)*.4*.2) + ((930) *.6 *.65) = 437.1 AF Sewer Plant Discharge (930) *.4 *.8 = 297.6 AF Allowable Reuse 640 – 437.1 = 202.9 AF
