results conference call for 2022. Today, we have with us, Mr. Andre Salcedo, Ms. Catia Pereira, Finance Director and Investor Relations Director and Mr. Marcelo Miyagui, Accounting Manager. And before I turn over to Andre Salcedo, I would like to share some information and instructions. This video conference is being recorded and have simultaneous translation into English. The presentation and recording will be available at the IR website of SABESP. I would also remind you that questions will only be taken in writing in the chat of this platform. Our conference shall last about one hour and 30 minutes. And we're going to save 45 minutes for Q&A of analysts and then journalists. To conclude, I would like to clarify that any statements made during this conference are regarding the company's businesses and projections for the future are only projections based on the assumptions of the company, as well as the information currently available to the company and do not constitute any results and involve risks uncertainties and premises, because they refer to future events, and therefore, these circumstances may have been or not. Investors should take into account, general operational factors and the industry take into account that they may change their results, which will be materially different in future projections. And now, I would like to turn it over to Mr. Andre Salcedo, who will start the conference.

Good morning. Thank you very much. I thank everyone who is been with us in these early months of our new management. I think investors, journalists and analysts for their presence, as well as the general public. For those who do not know me personally, I am Andre Salcedo. I have been assigned as President to Director last year, and I officially took over on January 13. Since then we have been learning about the company's performance, getting to know the team of managers of the company, so that we can have a more extensive view of what is in fact the aspirations for SABESP. I was given a free charge to take care of the company to turn the company into a more modern one, into an innovative innovating and inclusive company. And this is the mission that we're going to implement throughout this management. And to give you an idea of the work we're going to perform, we have already defined the new composition of the Board, so that we can align SABESP’s management with this strategic view, a view of modernity a better relationship with regulators with our clients. And also in terms of the end users. With a more integrated view, a company that thinks together that uses its resources, Human Resources, Finance resources rationally. A management, which is closer to people, internally and externally and a management which will pursue a full opening, including all stakeholders, regulators, shareholders, investors to understand what can be improved and how we can improve. And whenever possible, we will be as transparent. As possible, I'm very happy to be here in the company right now. We are at a moment where we're turning a page we will pursue new businesses, we want to grow, and we also want to…

Well, thank you, Andre. Now actually, I think it is Catia's turn to present the results.

Good morning, everyone. Thank you, Andre, for the introduction and very inspiring introduction. First of all, I am Catia Pereira. I started working in the company in early March. I am very new in the company, but it takes pleasure to be part of this team and help in this construction in the finance area, playing a role of turning the company into an efficient company with integrated processes so that the finance department permeates all of the other areas of the company, and as Andre mentioned, providing focus on the delivery of the operation, turning processes, more integrated, faster and more efficient. This is the objective and is aligned with the introduction, shared services, and this is going to be our journey for 2023. So now moving on to the next slide, I will start talking a little bit about volume. In '22, we saw an increase of 0.2 in terms of water volume. Basically, we see a decrease in residential area, but on the other hand, an increase in the commercial and industrial area. This only indicates life going back to normal after the pandemic. So we can understand that we are resuming our normal lives, moving from residential into life, into commercial and industrial. We see the same trend in sewage. We had an increase of 1.7, also an increase in the commercial and industrial area. And this was a little bit higher in sewage because all of the focus we've given on sewage, and with that, we can see the results. When we look at the whole, we're talking about a growth in the order of 0.9 in terms of volume. And the good thing about this is that when I have this migration and this change in the mix from residential to other categories, I…

And I'm going to ask the first question by Carolina Carneiro. Good morning. Our question is about costs. Another quarter where the company had a relevant increase in manageable costs, which was below -- above expectations, especially in PDD. So number one, with the new management, do you have a mapped plan to reduce these inefficiencies? Number two, when do you plan to announce this detailed plan? Question number three, how long do you think it will take to reach more adequate cost levels? Andre or Catia, who is going to answer? Well, I can answer this question. This question by Carolina was asked before Catia's presentation. I don't know whether it is possible to go back to Catia's presentation and the bar code, when she talked about individual costs. With that, we can help answer what she mentioned. So Carolina and those who are watching this presentation, we have done a lot in 2.5 months. We have a new strategy for the company, a new Board of Directors with the new proposals, with strategies that are already ongoing. We hope to have our assembly to implement everything. But based on what you can see here on the screen, the change in the management, review of processes, review of the strategic plan will have an impact in the allocation of people and the activities we have today. We have submitted a plan which is being analysed and this is something that we will share with you. We expect to have relevant reductions throughout the process. We will share with you once everything is concluded. So the general supplies, treatment supplies and services in general are being treated within the context of process review. We have created two centers. One is the CST, which will take care of contracts, hiring and…
