imbalance that has resulted in saltwater intrusion into coastal wells that endangers agriculture in the
region. The Water Recycling Project recharges the aquifer, providing 4,000 acre-feet per year of recycled
water for irrigation. This accounts for over 20% of the 18,500 acre-feet per year of coastal pumping
needed to halt seawater intrusion into the local aquifer.

Recycled Water
#47. (Describe) the recycled water currently being used in the supplier's service area,
including, but not limited to, the type, place, and quantity of use (10633(c)).
The amount of recycled water that is currently being used within the water service area is outlined in
Table 4.7.
#48. (Describe and quantify) the potential uses of recycled water, including, but not
limited to, agricultural irrigation, landscape irrigation, wildlife habitat enhancement,
wetlands, industrial reuse, groundwater recharge, indirect potable reuse, and other
appropriate uses, and a determination with regard to the technical and economic
feasibility of serving those uses (10633(d)).
#49. (Describe) the projected use of recycled water within the supplier's service area at
the end of 5, 10, 15, and 20 years, and a description of the actual use of recycled water
in comparison to uses previously projected pursuant to this subdivision (10633(e)).
In 2010, the City of Watsonville’s completed its upgrade of the wastewater treatment plant to include
tertiary treatment. It recycles wastewater for crop irrigation in a joint project with the PVWMA. The
treatment plant upgrade allows the City to produce up to 4,000 acre-feet per year of treated
wastewater. This figure can be met based on the demand of the agricultural users ordering water in
conjunction with PVWMA.
