Dominica’s rugged terrain is among the most aquatic of the Caribbean islands, and JARS Sales and Services Ltd has become one of the regional experts at implementing construction projects where rivers, streams, tributaries and other waterways pose unavoidable challenges. JARS knows about setting up water networks in tropical islands like Dominica.Dominica’s national water system involves distributing water from the island’s many natural sources through pipelines from reserved catchment areas. The infrastructural and engineering demands of the system are complex and JARS Sales and Services continues to be one of the leaders in addressing the evolving engineering issues. Knowledge of detailed applications like the placement of various valves and pumps and the selection of the ideal pipes are critical.
Understanding of the dynamics of gravity flow, particularly that related to mountainous and undulated terrain, which are common throughout the Caribbean, is important. When approaching a water project, JARS Sales and Services Ltd. researches carefully the scientific and environmental factors peculiar to the project. It examines every factor that contributes to the success of the project, including embracing some of the cultural and historical data that explain the behavior of the waterways.
JARS Sales and Services Ltd. also installs sewerage treatment systems. We work with both gravity flow set-ups and pump stations.
Carib Territory Water Supply Project: Phases 1 & 2
The Carib Territory is a section of the island reserved for the indigenous Kalinago Indians. In November 2006, the Dominica Water and Sewerage Company (DOWASCO) contracted JARS Sales and Services Ltd. to build the infrastructure for water expansion in the area. The main component of the project required JARS to construct in the village of Bataka, a reinforced concrete tank with the capacity to store up to 45,000 gallons of water.
JARS also installed 11,000 ft of 4" Ductile Iron pipe to connect the newly erected water storage tank to the water mains in the neighboring village of Gaullette River. JARS set up a series of pressure reducing valves along the water network. This included the laying of an additional 2,000 ft of 6" PVC pipes and 800 ft of PVC distribution mains at Bataka and Salybia respectively. In phase 2, JARS constructed another reinforced concrete water tank and distribution network in the Carib Territory. This tank, erected in the village of Concord, is able to hold up to 15,000 gallons of water.
Ross University Waste Water Treatment System
In March 2002, JARS Sales and Services Ltd. collaborated with Activille Tavernier and Associates to set up a waste water and treatment plant as part of improvements to the Ross University Portsmouth campus’ sewerage system. On this project, JARS installed four (4) sewage pump stations, interconnecting pipes and force mains, and constructed a treatment plant. The plant incorporated four (4) tanks. The final of which contained a re-circulating pump which sent the effluent to the gravel filter bed. The treated effluent then flows into a soakage pit system.
Roseau Water and Sewerage Sanitation Project
In November 2000, JARS Sales and Services Ltd. worked as a sub-contractor on the upgrading of the water and sewerage system in Roseau, Dominica’s city. The rehabilitation works involved the replacement of the existing clay lines, the laying of new pipes, and the installation of pre-cast manholes. On the water component of the project, JARS laid new PVC pipes and installed water connections along the city’s water distribution mains.
