In April 2022, russian forces blew up the Dnipro–Mykolaiv water pipeline in Kherson Oblast, which had supplied Mykolaiv with fresh water. For over three years, the city has been reliant on brackish water from the estuary, which is unfit for consumption.
Nearly 500,000 residents of Mykolaiv lost access to clean water.
Thousands of hectares of agricultural land are no longer irrigated.
1,200 kilometers of Mykolaiv’s water supply network have been damaged by the brackish water from the estuary.

Project implementation is gaining momentum — trench excavation, pipeline base preparation, and delivery of essential materials are underway.Works are carried out around the clock, with strict adherence to all technological requirements.
24/7 work continues on the installation of a twin-line pipeline and the simultaneous construction of three pumping stations.Within the intake channel on the Southern Bug River, four branches are being installed to transport water to Pumping Station No. 1 near Nova Odesa.
Core construction of the three pumping stations is nearing completion: electrical and pumping equipment has been installed.In the canal bed, a concrete slab foundation was constructed to ensure secure anchoring and stability of the pipelines, followed by backfilling of the intake channel in accordance with project specifications.The next phase — commissioning and system tuning.
As part of commissioning works, specialists test the system under medium operating pressure, verifying sealing, flushing pipelines, and releasing air.Pumping proceeds step by step.At the first stage, water from the Southern Bug flows through gravity pipelines into the intake chambers of Station 1. Once chambers are filled, water is pumped to the second lift station.After pressure reaches target levels, the next segment — from Station 2 to Station 3 — begins to fill.
The shortening of timelines became possible thanks to the high competence of the Autostrada team and the availability of the company’s own production facilities, which ensure prompt execution of works. This was further facilitated by the DESIGN&BUILD approach, where designers and builders work in parallel, achieving perfect synchronization of all processes.

Without subcontractors
Round-the-clock work
At all stages of the project’s implementation, Autostrada operates its own certified laboratory complexes, ensuring systematic quality control of construction materials and technological processes. This approach guarantees the project’s consistent compliance with national building codes, technical regulations, and European quality standards.
This is achieved by performing all work exclusively in-house, without the involvement of subcontractors.
A horizontal directional drilling (HDD) operation was carried out beneath the Inhul River to install the water pipeline.
The crossing is 462 meters long, with a depth of 14 meters — equivalent to a four-story building.This technology minimizes the impact on the river ecosystem and enables pipeline installation even under complex hydrogeological conditions.
Fiberglass Pipeline
The water intake system is equipped with a mechanical pre-filtration complex and an ultrasonic protection system that prevents aquatic bioresources from entering the pipeline.
