📋 Tender Overview
- Comptrollers Auditors also revealed problems in Basic Sanitation UnitsMother of God. - The Comptroller General of the Republic (CGR) alerted the District Municipality of Las Piedras that the infrastructure of the drinking water system valued at S/ 563,742.69, which is part of the project Creation of the water system and sanitary disposal of excreta in the town center of Lago Valencia, district of Las Piedras, province of Tambopata, department of Madre de Dios, has not been operational since mid-October 2025 due to deficiencies and components incomplete, which affects the purpose and quality of the service.
The project was approved on April 8, 2024 with an investment of S/ 2,012,279.80 and its purpose is to improve the conditions of access to basic drinking water and sanitation services in the town center of Lago Valencia, contributing to raising the quality of life of the beneficiary population and reducing the incidence of water-related diseases.
Control Visit Report No. 5907-2026-CG/GRMD-SVC, whose evaluation period was from April 21 to 27 as part of the Multidisciplinary Territorial Control Operation 2026 developed in Madre de Dios, reveals the absence of covers in the control valve boxes of the water system, allowing rainwater to accumulate inside and generating the risk of affecting the proper functioning and conservation of installed components. Also, it was verified that the 10 m3 reservoir has partial painting and does not have a top cover.
In both items, the contractor presented a 100% valuation; However, the situation described would generate the risk of recognition and payment for items not executed or partially executed, affecting the proper use of public resources. Furthermore, deficiencies in the supervision of the work would be evident, since conformity was granted to valuations that would not reflect the actual physical execution of the items, which could lead to the receipt of an unfinished work or with deficient components.
The control commission also revealed constructive deficiencies and components pending execution in the Basic Sanitation Units (UBS) of the project, which prevents the availability of the service and affects access to the beneficiary population.
The project includes the implementation of 34 UBS, of which 27 UBS were inspected by the Comptrollers auditors and it was possible to verify the lack of covers in sludge chambers in 11 UBS, the lack of covers in percolation wells in five UBS, the absence of ventilation caps in 13 UBS, the lack of knobs on doors in nine UBS, the installation of doors with unevenness in 14 UBS, painting deficiencies in nine UBS and other technical observations at 11 UBS.
Another finding of the control commission was the partial execution of the projects perimeter fence, valued at S/ 21,358, since it presented constructive deficiencies in its implementation, despite the fact that it was declared as a 100% executed item. This fact would generate the risk of not guaranteeing the protection and safety of the drinking water collection and storage infrastructure.
The Comptroller Generals Office, through the Regional Control Management of Madre de Dios, recommended communicating these facts to the head of the District Municipality of Las Piedras, with the aim of adopting corrective measures that allow the correct functioning of the work in order to address the need for sanitation services in the town center of Lago Valencia.
