Drainage & Drain-Line Jetting

Clearing and unblocking drain lines using high-pressure jetting machines and specialist chemicals.

The efficiency of drainage networks is fundamental to keeping buildings and facilities running without interruption

Any blockage or build-up inside the drainage lines can lead to water backing up, the spread of odours, the leakage of contaminants, and the shutdown of kitchens, bathrooms and operational facilities.

Drainage & Drain-Line Jetting — Evolution Projects

Evolution Projects provides integrated services for the inspection, cleaning and unblocking of foul and storm drainage lines, using high-pressure equipment, suction systems and specialist inspection devices to locate the blockage and treat it at source.

Our services cover internal and external networks, kitchen lines, manholes, inspection chambers, sump pits and storm water drainage lines, together with emergency response and preventive maintenance programmes for buildings and facilities throughout the State of Qatar.

Scope

What this division covers

High-pressure jetting

We use high-pressure water jetting equipment to remove blockages and build-up inside drainage lines by means of pressurised water directed through specialist cleaning heads.

The operating pressure and type of head are selected according to the diameter, type and condition of the pipe, achieving effective cleaning without causing damage to the network.

This technique helps remove

Hardened grease and oils.
Sediment and silt.
Soap residues and organic matter.
Scale and deposits inside the pipes.
Light roots and accumulated obstructions.
Dirt adhering to the walls of the drainage lines.

Rodding & cleaning of drainage lines

We clean and rod foul, commercial and industrial drainage lines, covering internal and external lines and the lines serving kitchens and sanitary facilities.

The work is not limited to opening the blockage temporarily; it aims to clean the line and remove the cause that leads the problem to recur.

The service includes

Opening partial and complete blockages.
Cleaning of main and branch drainage lines.
Treatment of slow drainage.
Removal of grease accumulations and solids.
Cleaning of kitchen and bathroom lines.
Rodding of storm water lines.
Testing of the water flow on completion.

Removal of deposits & build-up

Over time, layers of grease, soap, sediment and solids accumulate inside drainage lines, reducing the internal diameter of the pipe and weakening the flow.

The method of treatment is selected according to the type of deposit, the material of the pipe and the degree of blockage, avoiding the use of any material that could adversely affect the network or the environment.

We treat these cases using

Mechanical cleaning.
Pressurised water jetting.
Cutting and descaling heads.
Suitable cleaning materials where required.
Suction and removal of waste from the collection points.

Diagnosis & investigation before execution

Before cleaning works begin, our team assesses the condition of the network to determine the location of the blockage, its cause and the nature of the treatment required.

Correct diagnosis helps reduce the time on site and avoid random or temporary treatments.

The diagnostic process may include

Testing of the drainage points.
Inspection of the manholes and inspection chambers.
Determination of the direction of the lines.
Measurement of the water level and backflow.
Camera inspection of the pipes where required.
Identification of fractures, settlement or foreign objects.
Assessment of the condition of the line before selecting the cleaning equipment.

CCTV inspection of drainage lines

We provide a pipe inspection service using dedicated cameras introduced into the drainage lines to determine the internal condition precisely.

This service is important in recurring or unclear cases, and a photographic report with technical recommendations for repair or replacement can be issued where required.

Camera inspection can reveal

The location of the blockage.
Cracks and fractures.
Separation of joints.
Settlement or deformation of the pipes.
Root ingress.
The presence of foreign objects.
Accumulation of grease and sediment.
Areas of water leakage.

Cleaning of manholes & inspection chambers

We clean manholes and inspection chambers and remove the sediment and waste accumulated inside them, to ensure the continued flow of waste water and prevent the blockage from transferring to the main lines.

The work area is also fully secured and confined-space safety procedures applied where required.

The service includes

Suction of water and waste.
Removal of sediment and silt.
Cleaning of the internal flow channels.
Inspection of the inlets and outlets.
Cleaning of the walls and floors.
Inspection of the covers and frames.
Testing of the water movement on completion.

Cleaning of sump pits & pump chambers

We provide cleaning and maintenance services for sump pits and the pump chambers connected to drainage networks.

Regular maintenance of sump pits helps prevent pump failure, flooding and unwanted odours.

The works include

Suction of water and sediment.
Removal of solids and grease.
Cleaning of the floats and sensors.
Cleaning of the pump bases.
Inspection of the condition of the pumps and connections.
Verification that there is no blockage in the inlet and outlet lines.
Recommissioning and testing of the water level.

Cleaning of storm water drainage lines

We clean storm water drainage networks, gutters, channels and floor drains before and after the rainy season.

These works help reduce the risk of water pooling and leaking into buildings or operational areas.

The service includes

Cleaning of roof drains.
Removal of sand and dust.
Rodding of storm water lines.
Cleaning of external channels and drains.
Inspection of the manholes and drainage outlets.
Testing of the network with water.
Removal of waste obstructing the flow.

Scheduled preventive maintenance

We provide periodic maintenance contracts for drainage networks with the aim of preventing blockages before they occur and reducing emergency failures.

The frequency of the service is determined according to the nature of the facility, the intensity of use and the previous record of failures.

A maintenance plan may include

Periodic inspection of the drainage lines.
Cleaning of kitchen lines.
Cleaning of manholes and inspection chambers.
Cleaning of sump pits.
Inspection of the pumps and floats.
Cleaning of storm water lines.
Preparation of a record of observations and failures.
Issue of reports after every visit.

Emergency response around the clock

Our teams work to identify the problem, contain it and treat it in the shortest possible downtime, giving priority to hospitals, hotels, restaurants, schools and facilities operating around the clock.

We provide a rapid response to critical cases, including

Waste water backing up.
Blockage of the main lines.
Flooding of manholes.
Failure of kitchen drainage.
Sump pits filling up.
Failure of storm water drainage lines.
The spread of odours resulting from a blockage.
Leakage of waste water inside the building.
