Discussion ItemsDiscussion Items
• Definitions• Reporting changes and why• Integration with 2015 Recycled Water Survey• What happens to collected data
Code RequirementsCode Requirements
• California Water Code 10633 describes wastewater and recycled water reporting requirements
• No code changes since 2010• Slight modifications to requested reporting to
improve usability of the data
Wastewater: What it is and isn’tWastewater: What it is and isn’t
How does wastewater become water supply?
It’s not just a waste anymoreIt is regulated and monitored
as a waste by the RWQCBsIt is also a valuable water resource that can meet local water demands
BENEFICIAL BENEFICIAL USEUSE
Recycled Water DefinitionRecycled Water Definition
Water which, as a result of treatment of waste, is suitable for a direct beneficial use or a controlled use that would not otherwise occur and is therefor considered a valuable resource.
Water Code Section 13050(n)
Recycled Water DefinitionRecycled Water Definition
The legal definition does not specify the source of water . . .
• Municipal wastewater source• Agricultural reuse source• Industrial internal reuse source
UWMPs and the recycled water surveys track municipal recycled wastewater
Municipal Recycled Water TypesMunicipal Recycled Water Types
Title 22 covers a range of recycled water qualities•Secondary, Undisinfected•Secondary, Disinfected-23 •Secondary, Disinfected-2.2•Tertiary •Advanced

Recycled Water DefinitionRecycled Water Definition
• Beneficially, in a manner consistent with Title 22
• In accordance with a RWQCB permit (NPDES, WDR, or WRR)
Two requirements treated municipal water must meet to be classified as recycled water in UWMPs. It must be reused:
Why is Terminology ImportantWhy is Terminology Important
• Reduces confusion and incorrect classification of water
• Supports understanding of recycled water use• Provides clarity, especially with potential
changes in how recycled water is used– SWA (surface water augmentation)– DPR (direct potable reuse)
What Happened to the 2010 What Happened to the 2010 UWMP Wastewater Data?UWMP Wastewater Data?
• Because of inconsistencies and duplications in how the data were reported, it was not usable and was not released.
• Changes to the 2015 are implemented – in spite of no code changes – to support improved reporting

What is Different in 2015?What is Different in 2015?
• UWMP data will be integrated with statewide recycled water survey conducted with the SWRCB
• Guidebook Appendix M prepared to help clarify terminology– Disposal vs recycling– Supplemental water– Etc

What RW Data Will Collected?What RW Data Will Collected?
• Data primarily will be reported in tables, but information is also contained within text
• Five tables with variable reporting requirements
– Water Retail vs Wholesale– Recycled Water Users vs Non-Users and
Distributors vs Producers
Reporting in the UWMPReporting in the UWMP
• Wastewater or recycled water can be in a separate section or part of the water supplies chapter
• We’re asking for more background information and a RW system map
Don’t forget to mention alternative water supplies!

Completing Completing Tables Tables Rows
Row 1 Using the 2015 size of the UWMP area, identify what percentage (to the nearest whole number) of the service area is covered by sewer service.
Row 2 Using the 2015 population determined for the gpcd calculations (Section 5), identify what percentage (to the nearest whole number) of the population is covered by sewer service.
Row 3 Use as many rows as needed. For each collection agency and WWTP within the UWMP service area, provide the requested information
Row 4 Add the total amount of wastewater generated in 2015 within the UWMP area Row 5 Provide any comments important to data reporting in the table.
