Purpose : The purpose of this procedure/method of statement is to ensure that the requirement of the Contract Technical Specification for Site Set-up, Control of sewer Flow operation are complied with in all respect. This procedure covers all aspects of site Set-up, Control of Sewer flow operations from setting up to completion of the work wherever required as per the contract.

Scope : The manholes and sewers being worked on shall be isolated and bypassed such that they do not contain any sewage. This shall be achieved by plugging, and by-passing to diverting the flow or over pumping if required.

Purpose : Technical purpose of this procedure/method is to ensure that the requirements of the contract Technical Specification for CCTV Inspection/Deflection Survey operations are compiled with in all respects. The procedures cover all aspects of Pre/Post CCTV operations for sewers inspections survey.

Scope : Enable the evaluation of pipelines conditions, Provide a complete circumferential profile showing deflections within the pipeline, Enable decision on suitable rehabilitation method, Record general data of sewer network.

SPR PE

SPR PE : The SPR PE pipe rehabilitation process is a solution for restoring the hydraulic efficiency, reliability and integrity of aging sewers, storm drains and culverts. SPR PE liners can structurally rehabilitate brick, concrete, glass reinforced plastic or corrugated metal sanitary sewer and stormwater pipelines with diameters from 900mm to 3000mm.

Project Experience : SPR PE has been used to rehabilitate sewers, stormwater lines and culverts around the world. It has been proven capable of providing a structural liner for severely deteriorated pipelines, and has been installed under difficult site conditions with minimal community disruption.

SPR EX

SPR EX : SPR EX has been used to rehabilitate sewers, storm water lines around the world. It has proven capable of providing a structural liner for severely deteriorated pipelines, and has been installed under difficult site conditions with minimal community disruption. SPR EX liners can structurally rehabilitate brick, concrete, glass reinforced plastic or corrugated metal sewer and storm water pipelines with diameters from 150mm to 1050mm.

A smooth winding and expanding process: The pipeline is first cleared of debris and obstructions, cleaned and inspected. Locations if lateral connections or branch lines are logged. The SPR EX winding machine is lowered to the base of the access chamber through a standard opening. The PVC profile is fed through into the machine from an above ground spool. The SPR EX profile is wound in at a diameter smaller than the host pipe. The liner is held together at the smaller diameter by the secondary lock.

SPR ST

SPR ST : The SPR ST pipe rehabilitation process is a solution for restoring the hydraulic efficiency, reliability and integrity of aging sewers, storm drains and culverts. Where required for greater stiffness, the liner can be reinforced by simultaneously winding a profiled strip of steel under the tees of the PVC profile.

Project Experience : SPR ST has been used to rehabilitate sewers, storm water lines and culverts around the world with a diameter from 450mm to 1800mm . It has proven capable of providing a structural liner for severely deteriorated pipelines, and has been installed under difficult site conditions with minimal community disruption.

Purpose : Technical purpose of this procedure/method is to ensure that the requirements of the contract Technical Specification for Leak Sealing (Patch Repair) operations are compiled with in all respects. The procedures cover all aspects of Leak Sealing (Patch Repair) operations whenever required as per the contract.

Scope : The ‘Patch Repair’ system is used to provide an effective structural repair applicable for various pipe defects including leaking joints. The ‘Patch Repair System’ comprises of glass fiber matting to which is added a resin/hardener mix; the impregnated matting is inserted into pipe by use of a packer which is inflated, pressing the matting over the defect and tightly against the host pipe. The impregnated matting hardens to provide a structural repair under ambient temperatures, once cured the packer is deflated and withdrawn from the pipe.

Is a well-established method for trench less replacement of water pipe, storm water and sewer pipes. An existing pipe is replaced size-for-size or up-sized with a new pipe in the same location. The technique is the most cost effective when there are few lateral connections, when the old pipe is structurally deteriorated, and when additionally capacity is needed.

Pipe bursting involves the insertion of a conically shaped tool (bursting head) into the old pipe. The head fractures the old pipe and forces its fragment into the surrounding soil. At the same time, a new pipe is pulled or pushed in behind the bursting head. The base of bursting head is larger than the inside diameter of the old pipe to cause the fracturing and slightly larger than the outside diameter of the new pipe, to reduce friction on the new pipe and to provide space for maneuvering the pipe. The rear of the bursting head is connected to the new pipe, while its front end is connected to a cable or pulling rod.

The bursting head and the new pipe are lunched from the insertion pit, and the cable or pulling rod is pulled from the reception pit, the cable/rod pull together with the shape of the bursting head keeps the head following the existing pipes.
