1 Recent Utah Legislation Affecting Wastewater Reuse Water Environment Association of Utah Annual Conference March 30, 2006 Jerry Olds State Engineer

2 Objectives Basic Principles of Water Law & Reuse New Legislation Example – Water Right Considerations for a Reuse Project

3 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?

4 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.

5 Chapter 73-3c - C onservation and Use of Sewage Effluent (1995)  Drought of  New sources of water are limited  Cost to develop effluent  Litigation  Proposed Legislation – Water Task Force

6 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

7 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

8 Reuse Application Process  Public Notice – Newspaper & Web  Protest/Hearing  Decision Can deny, if inconsistent Approve with conditions  Judicial Review

9 Other Provisions  Annual reporting  Rulemaking  Infiltration water  Change - point of discharge, WQ Board Consultant with state engineer

10 EXAMPLE: Deer Springs City (Units: Acre-Feet) DivDepl.  WR #1 Spring A, 1.0 cfs or 350 af  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.)  Allowable Diversion930 Acre-Feet  Allowable Depletion640 Acre-Feet

11 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?

12 Deer Springs City (Cont’d) Current Depletion ((930)*.4*.2) + ((930) *.6 *.65) = AF Sewer Plant Discharge (930) *.4 *.8 = AF Allowable Reuse 640 – = AF
