Period:
April 2021 - December 2024
Location:
City of Delcevo, North Macedonia
Task:
Design and implementation of a resilient water supply system for Delčevo, combining surface and groundwater sources. The project included the rehabilitation and construction of hydraulic structures, wells, reservoirs, and a water treatment plant, as well as the installation of pumping, disinfection, and monitoring systems. Integration into a central SCADA system and a 250 kWp photovoltaic plant.

Delcevo Water Supply Project (DWSP)

The Delčevo Water Supply Project (DWSP) in North Macedonia improves the long-term drinking water supply for the town of Delčevo and the surrounding communities. It is designed to meet a future demand of around 16’500 population equivalents and combines surface water from the Loshana Dam with groundwater sources to create a reliable supply system.

The project includes new and upgraded hydraulic structures, groundwater well fields, reservoirs, transmission pipelines, a modern water treatment plant, and a 250 kWp photovoltaic power plant. With automated monitoring and connection to a central SCADA system, the new infrastructure supports efficient operation, better water quality, and a more secure water supply for the region.

Project Scope

Design & Planning

  • Detailed design, including expert assessments and building permit documentation
 

Water Intake & Regulation (A1–A2)

  • Rehabilitation of the existing pressure break chamber with flow measurement, automated valves, and lake level monitoring, powered by solar energy
  • Construction of a new downstream pressure break chamber with integrated valve chamber and water tank, powered by a hydro-generator with battery storage
 

Water Treatment (A3)

  • Modern drinking water treatment plant for raw water from the mountain lake Loshana
  • Four multimedia pressure filters and four activated carbon filters with a diameter of 3.5 m and height 4.8 m and a working pressure of 10 bars.
  • Coagulation and flocculation with static mixers and flow-proportional dosing
  • Disinfection using on-site generated chlorine dioxide with flow-proportional dosing
 

Groundwater Development (B1–B2)

  • Rehabilitation of existing wells with booster pumping stations
  • Drilling and development of two new groundwater wells
  • Installation of pumps, level and flow sensors, and UV disinfection
  • Full integration into the central SCADA system via 3G/4G communication
 

Storage & Distribution (C4–C5)

  • Construction of a new reservoir with two 400 m³ chambers
  • Rehabilitation of an existing reservoir
  • Installation of level and flow monitoring, as well as electrically actuated control valves
  • Integration into SCADA for remote monitoring and control via 3G/4G data modem
 

Photovoltaic Power Plant (D)

  • 250 kWp photovoltaic system with inverters, smart PV controller, and weather station
  • Automated monitoring and control via central SCADA system
 

Automation

  • Central SCADA System that connects all above stations.
