Specialized Hydraulic Works

Water Supply Systems (Systèmes d'Adduction d'Eau Potable)

Design, modeling, engineering, and turnkey construction of gravity-flow and pumped water supply schemes serving communities, camps, and urban centers.

IVM-SARL engineers complete water schemes starting from catchment sources (mountain springs, protected aquifers, river intakes) through raw water transmission lines, settling and filtration stations, treatment units, and bulk storage.

  • Hydraulic Dimensioning: Flow rate calculations, peak demand modeling, and pipe diameter optimization.
  • Water Treatment & Disinfection: Compact chlorination units, gravel/sand filtration, and coagulation chambers.
  • Complete Commissioning: Flow rate calibration, water quality testing (pH, turbidity, residual chlorine), and operational protocols.

Water Reservoirs & Storage Tanks (Réservoirs de Stockage)

Construction, structural reinforcement, waterproofing, and rehabilitation of large-scale ground and elevated potable water reservoirs.

As evidenced in our Lusenda water supply rehabilitation (featuring a documented 120 m³ reinforced concrete reservoir), IVM-SARL specializes in precision formwork, anti-corrosive reinforcement placement, specialized hydraulic concrete admixtures, and high-pressure manifold chambers.

  • Capacities: From 20 m³ community break-pressure tanks up to 250 m³ primary regional storage reservoirs.
  • Waterproofing: Food-grade hydraulic coatings, elastomeric joint seals, and negative-pressure water repelling layers.
  • Manifold & Valve Chambers: Heavy-duty PN16 flanged gate valves, bypass lines, overflow weirs, and drain pipes.
Distribution Networks

Water Pipeline Installation & Rehabilitation

Laying, trenching, butt-fusion welding, and rehabilitation of major raw water and distribution pipelines across rugged terrain.

Operating in Eastern DRC demands specialized equipment and skilled pipefitters able to excavate through volcanic rock, dense clays, and steep hill slopes. We install High-Density Polyethylene (HDPE PE100), Ductile Iron, and Galvanized Iron (GI) pipes adhering to PN10 and PN16 pressure ratings.

  • HDPE Welding: Electrofusion and butt-fusion welding by certified hydraulic technicians.
  • Trench Engineering: Laser grading, soft sand bedding, warning tape installation, and compaction.
  • Pressure Testing: 24-hour hydrostatic leak and pressure testing before backfilling.

Decentralized Grids

Mini Water Supply Networks (Mini-Réseaux d'Eau)

Turnkey decentralized mini-networks connecting isolated settlements, health centers, and schools to sustainable piped water.

Featured in our tender dossier via the rehabilitation of the Fandele mini water supply network in Mboko, these systems combine localized storage, secondary distribution mains, pressure break chambers, and clustered public distribution points for rapid community access.

  • Gravity-Fed Optimization: Eliminates fuel and electricity dependency for long-term community affordability.
  • Zoned Control: Individual sector gate valves allowing maintenance without shutting down the entire village.
  • Institutional Connections: Dedicated pipelines to clinics, health posts, and primary schools.
Groundwater & Village Access

Manual Pumps & Water Points (Pompes Manuelles & Forages)

Installation, mechanical restoration, downhole maintenance, and sanitary platform construction for deep-well handpumps.

Documented through works like the Nundu manual water pump rehabilitation in South Kivu, we service Afridev, India Mark II/III, and Vergnet pump models. We extract damaged rods and cylinders, replace foot valves, flush the borehole, and construct reinforced concrete sanitary aprons that block surface contamination.

  • Downhole Overhaul: Stainless steel connecting rods, brass/PVC cylinders, and nitrile rubber seals.
  • Sanitary Apron & Soakaway: C25 concrete apron with peripheral drainage channel preventing stagnant mud pools.
  • Spare Parts & Toolkits: Provision of standard maintenance toolkits to local village water caretakers.

Civil Infrastructure

Civil Engineering & Concrete Works (Génie Civil)

Heavy structural civil engineering, river intake weirs, retaining walls, box culverts, and institutional facilities.

Beyond hydraulics, IVM-SARL possesses extensive civil engineering capacity to execute structural concrete works, stabilization of unstable slopes, flood diversion dikes, warehouse and technical shelter construction, and administrative buildings.

  • Structural Concrete: Heavy foundations, columns, beams, suspended slabs, and waterproof water basins.
  • Intake Weirs & Catchments: Mass concrete dams and gabion revetments on mountain rivers.
  • Slope Stabilization: Reinforced masonry retaining walls and volcanic rock masonry works.
Drainage & WASH

Drainage & Sanitation Infrastructure (Assainissement)

Stormwater canals, culverts, soakaway pits, public standpipes (bornes-fontaines), and institutional VIP latrines.

We build storm drainage channels to prevent road erosion and flash flooding in urban Goma and rural towns. In water distribution points, proper drainage is vital to prevent waterborne disease vectors; we construct tiled aprons, grease traps, and soakaway filtration trenches.

  • Public Standpipes (Bornes-Fontaines): Multi-tap distribution points with hygienic drainage (as executed in Lusenda & Mboko).
  • Stormwater Canals: Trapezoidal concrete and stone-masonry canals with energy dissipators.
  • Institutional Latrines & Septic Systems: Multi-compartment septic tanks and bio-digester systems.

Infrastructure Maintenance & Rehabilitation

Preventative inspection contracts, emergency leak repair, valve replacements, and structural rehabilitation of aging assets.

Many water networks across North and South Kivu suffer from high non-revenue water (NRW) loss due to unmaintained valves, clogged air valves, and cracked concrete reservoirs. IVM-SARL provides systematic hydraulic diagnostic surveys and targeted rehabilitation to restore lost capacity at a fraction of replacement cost.

  • Acoustic & Pressure Leak Audits: Pinpointing subterranean bursts without destructive excavation.
  • Structural Concrete Re-lining: Epoxies, polymer-modified mortars, and waterproofing membrane restoration.
  • Service Level Agreements (SLAs): Ongoing preventative maintenance agreements for NGOs and municipal utilities.
