Community wastewater systems are complex undertakings with many environmental, health, safety and financial concerns to address.

Varela’s expertise in wastewater projects enables us to work with the inherent aspects of a community — its population, topography, geology, existing infrastructure, and water availability — to most effectively and safely manage and process wastewater.

As with most community engineering projects, Varela can assist with acquiring funding, with the foresight to ensure that what is designed and built today will serve the needs of the community far into the future.

  • funding strategies, acquisition of grants/loans from numerous programs available to our clients
  • planning, design, and construction management of new treatment systems and system improvements
  • existing systems evaluation and optimization
