11. Groundwater/Recovered Water Groundwater is pumped from several wells scattered across Peoria. Groundwater is pumped from several wells scattered across Peoria. Groundwater must be replenished to meet “Safe Yield” required by GWMA. Groundwater must be replenished to meet “Safe Yield” required by GWMA. Peoria stores water underground at four underground storage facilities. Peoria stores water underground at four underground storage facilities. Stored water then can be pumped from wells and is then recovered water. Stored water then can be pumped from wells and is then recovered water. In 2010 stored water recovered from wells was 6,567 acre-feet, or 24% of total. In 2010 stored water recovered from wells was 6,567 acre-feet, or 24% of total.

12. Recharge Program ADWR Water Storage Permits allow up to 85,520 acre-feet/year to be stored. ADWR Water Storage Permits allow up to 85,520 acre-feet/year to be stored. Sources include CAP and reclaimed water. Sources include CAP and reclaimed water. Peoria stores more water underground each year than it takes out in order to have water available when drought strikes.

14. Reclaimed Water Definition: the collection and treatment of wastewater from homes and businesses to be used where drinking quality water is not required Treated wastewater Treated wastewater Tested for compliance Tested for compliance Safe for application in Safe for application in non-potable uses non-potable uses

15. Assists conservation efforts Assists conservation efforts Saves drinking water Saves drinking water Delays costly expansion of water treatment facilities  lower water rates Delays costly expansion of water treatment facilities  lower water rates Readily available Readily available source of water Reliable, even during Reliable, even during times of shortage Supplies increase as Supplies increase as population increases Benefits of Water Reuse

16. Direct use Direct use –Irrigation –Decorative water features –Industrial processes Recharge Recharge –Geologic layers further clean reclaimed water –Replenish groundwater supplies  “bank account” for long-term sustainability Types of Water Reuse

17. Reclaimed Water Directly Delivered Direct use of recycled water for amenities, lakes, landscaping, golf courses, other non-potable uses Direct use of recycled water for amenities, lakes, landscaping, golf courses, other non-potable uses

20. Reclaimed Water vs. Gray Water Reclaimed water Reclaimed water –All water from a building goes to water reclamation facility Black water – kitchen sink, toilets Black water – kitchen sink, toilets Gray water – bathroom sinks, showers, bathtubs, washing machine Gray water – bathroom sinks, showers, bathtubs, washing machine –Effluent (a combo of gray water and black water) is treated by the city according to US EPA and AZ DEQ standards –Distributed back to users through separate pipe system for use where non-potable water is ok Gray water Gray water –Water from bathroom sinks, showers/bathtubs, and washing machine goes to onsite storage tank –Minimal treatment by filtration –Distributed to individual landscape for watering purposes

21. Reclaimed Water Quality Concerns Safety of reclaimed water in general Safety of reclaimed water in general –Quality regulated by US EPA and ADEQ –Contact with, or accidental ingestion, poses no significant concern for humans or animals Safety for children and/or pets playing on areas irrigated with reclaimed water Safety for children and/or pets playing on areas irrigated with reclaimed water –Water at night when areas aren’t in use Occurrence of overspray from sprinkler systems Occurrence of overspray from sprinkler systems –Water when there is no wind and maintain irrigation system so spray is not too fine Safety of infrastructure Safety of infrastructure –Reclaimed water system components identified by purple color –Reclaimed water systems are checked to ensure no cross- connection with potable water system

23. Storm Water Runoff Storm water runoff occurs when rain falls onto the ground and /or snow melts but is unable to infiltrate into the ground. It will then flow across the land, flowing to a nearby water body such as lakes and streams.

24. Urban Runoff Urban runoff is unable to infiltrate into the soil due to paved surfaces. Therefore, water flows into roadways, streets, sidewalks and eventually is collected through channels or storm drain inlets. These inlets are located in parks, rivers, and washes.

25. Runoff and Pollution Pollution from runoff occurs when the water is running down the streets. It is constantly picking up pollutants such as animal feces, chemicals, oil, fertilizers, and pesticides as well as many other contaminants.

26. What Is The NPDES Stormwater Program? The National Pollutant Discharge Elimination System (NPDES) Stormwater Program regulates stormwater discharges from three potential sources: Municipal separate storm sewer systems (MS4) Construction activities Industrial activities Operators of these sources may be required to receive an NPDES permit before they are able to discharge into local surface waters. Local surface waters are identified as streams, rivers, lakes or coastal waters.
