The company name is Consortium  Hydrotank  is a company whose mission is to meet the needs in everything related to storage and distribution of liquids, was created on July 31, 2013, has its address in the city of Barranquilla, the contact is (5) 3457717. This Consortium is a contractor of the multinational O-teck International, which is a company of the Orbis Group that offers solutions in the water market through an innovative portfolio, based on composite materials, alternative and with technological support with productive operations in Colombia. , Argentina and Mexico, commercially serves all of Latin America.

Hydrotank, is a consortium formed by a natural person named Carlos Vengal Pérez (20% Shares) and by the company Society PVC S.A.S. (80% Shares). The Hydrotank is consortium is in charge of the construction of the steel tanker in pernado, adduction and impulsion lines for the supply of 25,000 cubic meters of drinking water in the neighborhood 7 de Abril in Barranquilla. Its purpose is to supply potable water to the Expansion zone between the circumvallation road, Cordialidad highway and Career 38, as well as the neighboring municipalities of Galapa, Malambo and Soledad.

The purpose of the project is "Optimization of the potable water supply system for the south-western zone of Barranquilla", contemplating the construction of a steel tank, with thermo-toxic coating, through the pernado system, for the storage of drinking water, and the installation of 48 "and 42" diameter conduction and distribution pipes respectively. The construction of the megatank started on February 9, 2015.

During the audit of the Hidrotanques consortium, I had the support of the Donaldo Engineers, and Alejandra Margarita Olmedo.

Below I detail the findings found on the site of the construction of the steel tanker with thermo-toxic coating, using the pernado system, for the storage of drinking water, and the installation of 48 "and 42" diameter pipes and distribution pipes respectively. For the abduction and drive lines.

1.      Hydraulic tests have not been carried out in the maximum time.

2.      The megatank has been assembled since February 20, 2017.

3.      The project comprises three elements, the metallic tank (This is 98%), the loading pipe with a diameter of 1,200 millimeters (99%), and the discharge pipe, with a diameter of 1,100 mm (94%).

4.      Experts say that the slope where the megatank was built has no stability to contain the weight of 25,000 cubic meters of water.

5.      On April 13, 2018, the District Mayor's Office of Barranquilla filed a reformulation request "to incorporate the stability of the land to the project", a component that is not part of the scope of the initially viable project before the Ministry of Housing.

6.      The Autonomous Regional Corporation of the Atlantic opened a sanctioning investigation that began in 2016 against the Company Triple A, which designed and operated the tank- "for having developed the activities of descapote, leveling, and compaction of land" without environmental license.

7.      A consulted surveyor expert says that if the tank is built on the upper part of a slope, whose soil is clay, it is certain that due to its condition as a reservoir of wáter, added to the runoff as a consequence of the rain, infiltrations will take place. could result in the sliding of the upper layer and the consequent destabilization of the slope.

8.      The Atlantic Risk Management Plan document states that the neighborhoods of the southwestern slope of the city of Barranquilla, including April 7, and the neighboring municipality of Galapa, present a geological risk of mass removal, that is,  landslides, landslides and rock falls.

9.      The engineer Iván Zapata, explained that the contractual activities have not yet finished and must continue with the hydrostatic tests, which include the pipe of impulsión of 1,200 mm-arrival of the tank and distribution of 1,100 mm and sealing; that is, to verify that the tank does not leak or leak, so that the wáter remains stagnant in that container.

10.  It is necessary to adjust the designs of anchors because there was a displacement of the pipe, which is why the tank tests were delayed. The redesign of this part of the project was in charge of Triple A.

Non conformities:

1.      In the environmental policy of the Hidrotanques Consortium there are activities or operations that are not supported by environmental action.

2.      Environmental policy does not contain the commitment to continuous improvement of the Environmental Management System.

3.      Significant environmental impacts have not been defined.

4.      The environmental management program does not specify the responsible person.

5.      The control of the calibration equipment has not been fulfilled (Valves).

6.      The responsibility to handle non-conformities with the Environmental Management System has not been defined by the Hidrotanques Consortium.

First Conclusion:

1.      To practice the quality tests to the infrastructure so that the Consortium Hidrotanques makes the physical delivery to the operator of the potable water system (Triple A Company) for its later start-up.

2.      In order for the megatank to enter into operation. The Triple A company must connect to the southwestern drinking water network through a junction on Circunvalar Avenue, at the height of Villa San Carlos. These works are contracted and have a term of execution of 3 months.

3.      Among the complementary activities are, among others, the slope protection of the hill where the mezzanine megatank is located, the chlorination house, the house for photovoltaic cells (solar panels) and all the tasks corresponding to the management of surface water. , the same as the closing and installation of lighting poles.

4.      The estimated date of completion of the works contracted by the Metropolitan Area is projected for next April 15, 2019.

Second Conclusion:

1.      The construction of the megatank started on February 9, 2015, with a delivery time of 10 months, the project has not yet been completed.

2.      In order to comply with the totality of the execution of the project, the drainage and protection works required on the slopes of the Sevilla hill where the megatank is located must be carried out, as well as the complementary electrical works for lighting and for valve operation. And chlorination system.

3.      Additionally, progress must be made in the tasks of supplying and installing new pipes for the arrival to the megatank, and modification of detail designs in the installation of valves and complementary accessories.

4.      Currently, the project is in progress, developing the activities contemplated according to the last reformulation approved by the technical committee of August 23, 2018. Once the works are completed, the storage capacity of drinking water in the southwestern sector of Barranquilla from 0 to 25,000 m3.

5.      Environmental engineering concrete structures are defined as storage, flow and treatment structures for liquids and other related materials such as solid waste.

6.      The purpose of these requirements is to establish the design and construction methods that allow the structural safety objectives produced for environmental structures to be met.

Have a design that controls cracking and cracking to prevent the flow of liquids between the inside and outside of the tank.

First Recommendation:

1.      To the consortium hydro tanks establish a new schedule agreed with the multinational O-teck to carry out all pending activities, and finally deliver the project to the operating company of the megatank.

2.      Independent of contractual, financial, and legal issues. The effort should be directed to the total completion of the megatank, performing the hydraulic tests.

3.      Culminate the load pipe with a diameter of 1,200 mm, and the pipe with a diameter of 1,100 mm of discharge.

Second Recommendation:

1.      Carry out the corrective and preventive actions related to the Non-Conformities evidenced in the findings of the on-site audit.

2.      It is detected that the preventive actions are in fact corrective because there are previous non-conformities.

3.      There is no documented evidence of the meetings of the Environmental Management committee in which the suitability of the opening of the actions is decided, contrary to what is specified in the internal procedure of the Hidrotanques Consortium.
