Ancalle Engineers (originally CA Engineering) is a family-owned professional services practice founded in 1992 in Puerto Rico, specializing in water/wastewater and water resources engineering. It designs and manages infrastructure for water treatment and distribution, wastewater collection and treatment, and stormwater management. Licensed in DC, Georgia, Illinois, Maryland, Puerto Rico, Texas, Virginia, and the US Virgin Islands, it has completed over 800 projects in the United States and abroad.
Design of water treatment and distribution systems for drinking water, irrigation, and industrial use.
Design of municipal and industrial wastewater treatment and collection systems, including activated sludge, bio-towers, and sequential batch reactors.
Design of stormwater control structures to reduce flooding and improve water quality for residential, industrial, and commercial developments.
Hydraulic studies and floodplain modeling supporting FEMA FIRM revisions and NFIP compliance for rivers, bridges, and culverts.
Design, operation, and rehabilitation of large reservoirs using sediment transport and deposition models.
Water resources protection through environmental science, limnology, and ecology, covering water quality, stream restoration, and ecological assessment.
Guánica, Puerto Rico | Copamarina Beach Resort & Spa | Hospitality
Design of a 52,000 GPD MBR wastewater treatment plant, using the Kubota Submerged Membrane Unit. This zero-discharge plant discharges its effluent through irrigation of the resort grounds.

Mitigation of the frequent flooding of the UPRM Campus due to low hydraulic capacity of the channelized Quebrada de Oro. Design of two large detention areas upstream of the flooding area to reduce the peak discharge in the channel. This project also includes hydraulic modeling of the stormwater system using EPA SWMM and recommending modifications to improve the system to avoid frequent flooding.
