The declaration of a Deficit Zone must be posted on the institution's website from the moment of said declaration. The investment works that will gradually resolve the detected technical and operational insufficiency will be defined by AyA, and the "Percentage Flow Allocation Methodology" defined by the UEN for GAM Systems Optimization and Peripheral Systems Optimization will be applied for the percentage distribution of the flow introduced, both for current customers and for availability and water capacity requests for the cases established in subsection 129 of Article 7 of this regulation.
(Thus amended the previous subsection through session No. 2021-84 of December 21, 2021) 132. Influence zone (Zona de influencia): Geographical area of potential territorial expansion of water and sanitary sewer services where the public service provider is empowered to authorize expansions of the public service networks, provided that this does not imply enabling zones of absolute restriction, generating water stress on the available resource, or compromising the capacity or water or hydraulic conditions of the existing water supply system or sewer and treatment system to the detriment of the served community or any eventual new developments. In the case of delegated systems, this zone will be determined by the Sub-management for Delegated Systems Management.
133. Maritime terrestrial zone (Zona marítimo terrestre): Strip of land administered by the corresponding Municipality, with a dimension of two hundred meters wide along the entire length of the Atlantic and Pacific coasts of the Republic, whatever its nature, measured horizontally from the ordinary high tide line and the lands and rocks left uncovered by the sea at low tide, according to Law on the Maritime Terrestrial Zone, No. 6043 and its eventual amendments. For all legal purposes, the maritime terrestrial zone includes the maritime islands, islets, and rocks, as well as any land or natural formation that protrudes from the ocean level within the territorial sea of the Republic. Cocos Island is excepted, which will be under the direct domain and possession of the State, and those other islands whose domain or administration is determined in accordance with Law No. 6043 and its eventual amendments.
134. Environmental restriction zone (Zona de restricción ambiental): Territorial surface delimited by geomorphological conditions or risk zones, protection zones, and protected areas or state heritage reserves where, by legal provisions or territorial planning at the local, regional, or national level, service availability approvals or connections for the provision of water supply or sanitary sewer services, or both, must not be approved by a public service provider.
135. Service restriction zone (Zona de restricción de servicios): Coverage zone or influence zone of a public service provider where the water or hydraulic conditions of the existing systems prevent meeting the demand, expansion, or optimal provision of services due to a lack of water, hydraulic, collection, or treatment capacity.
This type of zone will require an express declaration through an AyA Board of Directors Agreement, which must be published in the Official Gazette La Gaceta. The foregoing will empower the public service provider to suspend the granting of availability certificates and new drinking water and/or sanitary sewer services.
