APPROVAL OF MINUTES
Ms. Marruffo asked if everyone had a chance to review the April and May minutes and if there

Ms. Coleman made a motion to approve both sets of minutes and Ms. Stockseth seconded the
motion.
ELECTION OF OFFICERS
Ms. Marruffo stated that the committee needed to elect a Chair and a Vice Chair and asked if
there were any nominations. Ms. Serrato stated that the committee needed to have a clear
understanding of the group's expectations, the frequency of meetings, and the level of
involvement for the Chair and Vice Chair. Ms. Marruffo stated that in her meeting with Ron
Massey and Ed Garafia, the committee, especially the Chair, would serve as a spokesperson for
the Committee. The Chair would have the opportunity to advise the Mayor, Council Members
on water supply, water rates and review water conservation program. The Chair would lead
committee meetings and offer the staff advice in terms of direction. Ms. Coleman stated that she
was aware that some of the members wanted to have their role defined. Ms. Marruffo stated that
she had done research to see if the ordinance identified the duties of the committee. Ms.
Marruffo stated that the staff was identifying the duties of the committee and would present them
at the next meeting. Ms. Serrato asked if the committee would be taking a formal approach or
passing resolutions to Council or just give advice. Ms. Marruffo stated that City staff would
have the primary role of presenting items to the City Council. The committee would serve the
same role as other City committees. She stated that from time to time, a suggestion, or maybe an
expansion, deletion from an ordinance might come before the committee and recommendations
could be made to the Mayor and City Council Members.
SCANNED
Ms. Coleman stated that the City Manager had mentioned that the committee could only make
recommendations to the staff and that the committee should reduce information down to laymen
terms so that community can understand. Mr. Johnson stated that the committee would be able
to apply some pressure on some suggestions or ideas on water resources.
Ms. Marruffo requested that the members reintroduce themselves to each other and provide
technical information on their background so that the committee members could make their
decision for the position of Chair and Vice-Chair.
Ms. Stockseth asked if the Chair would be in charge of running the meetings. Ms. Marruffo
stated that the Chair would work closely with the City staff to organize the committee agendas,
presentations, etc. Mr. Johnson stated that the committee needed a chair that could spend time
and was familiar with the projects. Mr. Johnson nominated Ms. Serrato to serve as Chair to the
Water Resources Advisory Committee stating that we she was familiar with water issues. Ms.
Serrato stated that she would be willing to serve as Chair. Ms. Stockseth stated that she would
be willing to serve as Vice-Chair. Ms. Serrato stated that in the past she had served on
committees when there were two Co-Chairs instead of a Chair and a Vice-Chair and that this
procedure worked very well. Ms. Marruffo stated that she would have to check with City
Secretary's Office to find out if the committee could have two co-chairs instead of a Chair and
Vice-Chair.
PRESENTATION ON GRAY WATER
Art Sosa, Acting Director of Development Services, and Leland Kirbow, Sr. Chief Plumbing and
Mechanical Inspector, gave a presentation on the proper use of gray water. Mr. Sosa stated that
the ordinance approving the use of gray water was effective September 1999. The ordinance set
in motion allowances for use of gray water. The Building Department enacted in the Plumbing
Code allowances for gray water. Copies were distributed of the Ordinance and an Appendix C-
101 (gray water recycling systems), which are written in the Technical Inspection Codes. The
City amended Appendix C to add, the term "and gray water/condensate irrigations. Basically
what is covered in Appendix C is gray waters can be used for all items outlined in third
paragraph exceptions to 301.3 connections to drainage systems. Mr. Kirbow stated that
originally the Board voted to amend the gray water and condensate drain and washing machine
drain. The amendment was worded to say, "you will furnish the drain connected to the sewer,
the condensate drain, and washing machine drain and if you wanted to use these two waters for
irrigation to drain onto the ground that you provide an alternate drain and move the hose to one
side and drain it into the ground. The Code states that you had to have the drainage system in the
sanitary sewer, which is an alternate method, as long as it was not sprayed nor stored. A resident
can revert to draining gray water into the sanitary system at any time. Mr. Sosa stated that the
Board and staff felt that washing machine discharge could be problematic whenever a household
utilizes cloth diapers. Mr. Sosa stated that in 2002, the City is making a move to correct it and
back to what the Board wanted. Mr. Kirbow stated that the big problem with TNRCC is with
storing the water. Section C101.4 states that gray water cannot be retained for more than 72
hours. In our amendment we did not address storing the water at all, but it tells you that you
cannot use the water after it is stored for 24 hours. At the time, TNRCC was telling us we
couldn't store over 24 hours without a permit. Then, someone had contacted TNRCC and they
denied they had said it. Right now we don't know where TNRCC stands. Right now TNRCC is
allowing that water be drained to the ground,but that any water that is held in a container cannot
be stored for more than 72 hours. Staff does not know what TNRCC requires. Mr. Sosa stated
2
that the model code was used to draft the item. Ms. Coleman asked if this was in effect now and
if it was being used and how the City knew if it was being done correctly. Mr. Kirbow stated that
if it starts running into someone else's property, the City is going to know about it. The technical
construction code requires building improvements comply with the code. The City does not have
a maintenance code; therefore someone could change the plumbing the day after the inspection
and we would not know about it. Ms. Coleman asked if there was any legal liability on the City.
Mr. Sosa stated that if a customer complains about a neighbor who is allowing gray water to
puddle onto their property, the City would investigate and handle it was a nuisance complaint or
mitigate it as a violation which would be forwarded to Municipal Court. Mr. Sosa stated that the
City works mostly on a complaint basis.
Mr. Johnson asked about the Section 101.6 regarding disinfection of gray water and if gray water
systems had to comply with the requirements. Mr. Sosa stated that we do not require the
installation of a disinfection system for gray water systems. He pointed out that the City's water
maintains a chlorine residual. Ms. Stockseth asked about the type of soaps used in gray water.
Mr. Sosa stated that it was part of the Code. Ms. Stockseth stated that there should be a
requirement to use low phosphate soap. After much discussion, it was decided that residents be
encouraged to use low phosphate soaps or to provide a link on the Water Department's web site
to a consumer-advocate web site.
There was discussion regarding the use of condensation water. Mr. Sosa stated that households
could hook up a drain line to a drip hose and place it around the foundation of the house. This
would provide a constant moisture level around the foundation during the summer. Key element
of condensation water is that it forms algae. The line must be maintained or it will clog up,
causing it to backflow into the unit.
There was some discussion regarding the use of air conditioning condensation. Mr. Sosa stated
that Jay Reining did some research regarding the ordinance, which was adopted in 1999. The
City hoped to clear up within the adopting of the International Code in September 2002. Ms.
Marruffo stated the need to get the information on usage of gray water to the citizens was a very
important issue. She stated that she would like to have a PSA done and possibly work with Mr.
Kirbow and Ruth Blake so the public can understand the concept to save water resources. Mr.
Sosa stated that they had been getting about 1,400 hits a month on their website and could
possibly link with Water Department's web site.
DROUGHT CONDITIONS
Ms. Marruffo provided a PowerPoint presentation. She reported that today's combined reservoir
system level was at 45.4% as compared to 34.5% one year ago. Ms. Marruffo stated that the City
had revised the Drought Contingency Plan in April 2001 and September 2001. The Plan
provides for trigger action when the combined reservoir system reaches 50%, 40%, and 30%
level. Certain measures are implemented depending on the rule.
Ms. Serrato asked if the citizens were allowed to water their yard only once a week, would it be
enough. Mr. Johnson stated that you could grow a reasonable yard if you only water once a
week. Ms. Serrato asked if the City were to approve an ordinance to allow once a week watering
would it hurt the irrigation business. Mr. Johnson stated that people are not going to let their
yards die, that some people are selfish and they water whenever they want to even though once a
week watering does work. Ms. Serrato stated that citizens might follow that rule if there were an
3
•
incentive, etc. Mr. Johnson stated that it might improve business because people would want to
set up an irrigation system. Ms. Marruffo stated that she had talked with Cheryl Soward with the
City's Public Information Office about a campaign on how to educate people on watering once
every 5 days.
Ms. Stockseth stated that going to once a week lawn watering based on the last number of your
address would be better than what the City did last August. Mr. Kent stated that the City had
done this in 1996. Ms. Serrato asked if we had any numbers on how much water was saved
when we did it in 1996. Ms. Marruffo stated that she would have to go back and look up the
numbers.
Ms. Marruffo distributed copies of the City's Drought Contingency Plan and stated that the
following two items would be discussed at the next meeting:
1. What additional measures are needed?
2. How successful are the drought measures currently in place?
Ms. Marruffo stated that the committee review the City's Water Conservation Plan and the
programs currently in place. She stated that the committee should consider educational and
outreach programs that produce quantifiable water savings. Mr. Johnson stated that there were
concerns when we were in a drought several years ago that other cities would not comply with
the measures. Ms. Marruffo stated that we do have one or two communities that do not comply.
Ms. Serrato stated that the City of Kingsville has previously refused to implement drought
contingency measures, but that just recently they had implemented a voluntary conservation
program.
Mr. Kent asked about the current water blend ratio from Lake Texana. Ms. Marruffo stated that
it usually runs 50%to 60%Lake Texana with the remaining coming the Corpus Christi Reservoir
System.
Ms. Marruffo stated that the next meeting needed to be scheduled. Ms. Marruffo stated that as
drought conditions worsened, the committee might consider meeting more than once a month.
Ms. Coleman stated that she understood that the committee was only supposed to meet four times
a year. Ms. Marruffo stated that once the Committee got on solid ground and drought restrictions
were lifted, then the meeting schedule would be reduced to four times a year. The Committee
agreed to meet on the fourth Thursday of the month. The next month was scheduled for July 25.
Mr. Kent stated that some Port of Corpus Christi officials wanted to make sure that the City
actively pursued the Garwood Irrigation issue. There was concern regarding securing right-of-
ways and that it was being done differently than from the Mary Rhodes Pipeline. Ms. Serrato
stated that the Garwood issue along with the two co-chair issue be discussed at the next meeting.
Ms. Marruffo stated that the committee would also review the conservation plan.
Mr. Kent also brought up the subject on the Governor's desalination plan and that we try to make
Corpus Christi a more attractive place for a possible plant. Ms. Serrato stated that Florida
maintained laws allowing for the construction of desalination plants, but in Texas, there are no
laws in place. If the committee is going to make a recommendation to the Council, Ms. Serrato
stated that the Committee needed to make its preferences known.
