Costa Rica is advancing several waterworks in Guanacaste province, of which some are publicly financed while others were funded with international aid.

In total, the national water and sewerage institute AyA is carrying out 16 projects across the province. All projects aim to increase potable water access in the region and thus include new aqueducts as well as upgrading existing ones.

The works require investments of 33bn colones (US$58.2mn) and are being developed under a comprehensive program for Guanacaste's water supply (PIAAG), part of coordinated efforts between different government entities, among them the planning and environment ministries, and the National Service of Underground Water, Irrigation and Drainage (Senara).

Around 280,000 residents in the localities of Abangares, Bagaces, Cañas, Carrillo, La Cruz, Liberia, Nicoya and Santa Cruz are expected to benefit.

Three projects address salination problems of water sources in coastal areas, including the Santa Cruz, Las Tancas-Pagagayo and the Sardinal-El Coco-Ocotal aqueducts.

Improvement works are carried out on the Liberia and Nicoya aqueducts, while efforts to deal with arsenic pollution are being developed at the aqueducts of Bagaces and Chinese-funded Cañas-Bebedero.

Three projects entailed the reconstruction of aqueducts damaged during hurricane Otto in November 2016 and have already been completed.

These works were financed with a US$10mn grant from the United Arab Emirates, which will finance 25 more aqueducts.

The completed works were executed on the El Porvernir, El Gallo and Belice aqueducts operated by communal water and sewerage associations (Asadas). Costa Rica's President Carlos Alvarado and AyA president Yamileth Astorga inaugurated the aqueducts during a weekend visit to the province.
