Advances in Latin America Wastewater Infrastructure
January 27, 2011
Vast areas of land are being deforested to build new communities for the ever-growing population. The catch-22 is that while this land is being developed for peoples’ use, the deforestation is also causing harmful runoff to drain into the rivers and this is drastically impacting the peoples’ clean water source. Industrial growth in Latin America is steadily growing as well and these industries and business need clean water to manufacture goods. These industries consume clean water at a significant rate, as well. The collection, transportation and treatment of wastewater allows the use of reclaimed water for many needs.
Following are some of the advancements being made:
- Chile, Brazil and Colombia are working very hard to update and upgrade all wastewater treatment infrastructure.
- Mexico, due to its proximity to the United States, has embraced some of the same rules and regulations related to water and wastewater management that the United States uses (the Rio Bravo/Rio Grande Water Treatment Treaty is an example).
- Panama has initiated a complete revamp of the sewer collection system to divert all the wastewater to treatment facilities in an attempt to clean all the shores and beaches.
- Aruba, one of the pioneers in wastewater treatment and reclaimed water re-use in Latin America, is in the process of building a second wastewater treatment plant.
- Puerto Rico and the USVI have been working very hard to repair and restore all the wastewater collecting systems, including pipelines, manholes, lift stations and treatment plants using state of the art technology and products.
Many 100 percent-solids, resin-based products are not only friendly to the environment, but also for users, as well. Today’s more advanced materials add the versatility of being able to be applied in the specified thickness in just one coat. This eliminates the need to come back for two or even three re-applications to comply with specifications. Concrete, brick and steel can be protected with these resin-based products, stopping the corrosive attack and destruction of structures exposed to them.
Airless spray technology helps in the application of protective coatings in a very fast and accurate manner, ensuring a great penetration and bonding onto the surface. The end result is a longer service life to the municipality and/or owner of the facilities.
