Status of the Basin and Administration of the Judgment

3.3.2 Recycled Water Recharge
Prior to March 2010, Beaumont’s recycled water from Wastewater Treatment Plant No. 1
was discharged at Discharge Point No. 1 (DP-001) in Cooper’s Creek where it infiltrates into
the San Timoteo Management Zone and outside the Beaumont Basin. In March 2010,
Beaumont began deliveries of recycled water to Discharge Point No. 7 (DP-007), located
along an unnamed tributary of Marshall Creek, as shown in Figure 3-3. It is believed that a
portion of the recycled water discharged at this location reaches and recharges the
Beaumont Basin; in which case, this would be considered a new source of supplemental
water for which Beaumont should receive credit pursuant to the storage agreement with the
Watermaster and Section 5.4 of the Rules and Regulations. Technical documentation of the
amount of recycled water that reaches and recharges the Beaumont Basin would need to be
prepared by Beaumont and considered and accepted by Watermaster.

In CY 2013, the City of Beaumont discharged an estimated 3,061 ac-ft of recycled water at
DP-001 in Cooper’s Creek and an estimated 530 ac-ft at DP-007. Monthly discharges at DP-
007 vary slightly seasonally and averaged just over 0.5 mgd. Monthly recycled water
discharges by the City of Beaumont since 2007 are summarized in Table 3-5.

3.3.3 New Yield Stormwater Recharge

Before accounting for any new yield resulting from the recharge of local surface water, not
initially considered as part of the Basin Safe Yield, Watermaster needs to develop a
methodology to quantify and credit the New Yield to the party that creates the new recharge.
According to Part VI Paragraph 5.V of the Judgment, Watermaster shall make an
independent scientific assessment of the estimated new yield created by each proposed
project. It is our understanding that Beaumont has been recharging local waters at various
locations in the Basin and would like to receive credit for the New Yield developed. For
Beaumont to receive credit however, Watermaster will need to develop the methodology to
compute and credit the New Yield dating back to February 20, 2003.

3.4 Water Transfers and Adjustments of Rights

Section 7 of the Watermaster Rules and Regulations provides for the adjustment of rights by
and between Appropriators and Overlying Parties. This section indicates that Watermaster
shall maintain an accounting for all transfers and include said transfers in the Annual Report
or other relevant document. There are three types of transfers that Watermaster accounts
for: a) transfer of water rights and/or water in storage between Appropriator Producers, b)
transfer of water rights from Overlying Producers to an Appropriator Producer in exchange
for water service, and c) the allocation of unused Overlying Water to the Appropriator Parties
based on their share of the Operating Safe Yield.

3.4.1 Transfers between Appropriators

According to Section 7.3 of the Rules and Regulations, an Appropriator may transfer all or a
portion of its production right or water in storage that exceeds its supply needs to another
Appropriator. In January 2008, the SMWC and the BCVWD entered into a transfer
agreement that allows BCVWD the option to purchase all water that SMWC determines to be
