The project to expand and improve the drinking water and sanitary sewage system of the city of Matagalpa, is aimed at solving the current supply and installation problems affecting important sectors of the population and generating the installed capacity needed to meet the demand of the population expected at the end of the 2023-2043 design period.

AP component

The main scope of works carried out in this process are:

  • Waterworks: Conventional side outlet on the right bank of the Tuma River, which includes one (1) pumping station.
  • A drive line from the intake to the PTAP site with three (3) pumping stations in series.
  • PTAP(1) (potable water treatment plant) with capacity of Q=790.9 lps. Which is designed in Phase 1: 4 modules Phase II: One (1) module
  • Construction of 3 vitrified steel storage tanks of 7,023m3 capacity to store a total volume of 21,071m3.}
  • A gravity conduction line to connect the stored volume to the PTAP output with the manifold ring pipe.
  • Extension of the internal distribution network to the different sectors of the City of Matagalpa.

AS component

The main scope of works carried out in this process are:
  • Collection Network, 77.85 Km of pipes with diameters Ø150 mm to Ø900 mm, for main and secondary collectors. With 7,654 home connections.
  • Pumping stations, known as EBAR#1 Nueva – Sister Maria Romero; EBAR#2 New – Habitat and EBAR#3 New – Waswali.
  • Drive lines: HDPE 5: Ø650mm (EBAR 1), Ø700mm (EBAR 3) and PVS SDR-17 Ø100mm (EBAR 2).
