Failing to gain confidence in general pump hire contractors to satisfy the sheer scale and stringent requirements for a project, it becomes evident, there is only one company in the country, with the agility, resources and commitment to manage the scope of any size project. Welltech has the technical team to carry out site investigation and will immediately deploy a team to provide a bypass solution, no matter how technically challenging.

Bypass Overview

Welltech’s Bypass Division specialises in the successful pumping and bypassing of sewer and waste water across the nation and internationally, incident-free. This division’s establishment has largely been advanced by an industry in dire need for a large scale operator with the unique capacity to manage flow rates in excess 14,000L/sec. 

Being able to pump high flow rates is only the beginning. We understand and embrace that to successfully carry out large scale bypass operations, all details and possible scenarios must be identified and understood. Welltech’s Bypass Division ensures each project component is considered, planned and executed using the most advanced equipment and practices.

Our research and development team constantly source, test and develop the latest equipment and technology available around the world before we deem it a viable addition to our Bypass operations.

Clients understand that once the Welltech team have developed, endorsed and introduced a new product into the fleet, it is guaranteed to produce reliable, quality results.

Our Bypass Division ensures each project component is considered, planned, and executed using the most advanced equipment and practices to deliver incident-free, completely controlled Bypass solutions, every time.

When your next bypass project demands an innovative solution, offering the best equipment and a dedicated team, Welltech has you covered.

Bypass Project Scope

Bypass installation is just one part of a much larger project, and often design engineers aren’t trained in bypass design, fortunately, Welltech is. Welltech can not only provide high-quality equipment, we also have the engineering knowledge and installation expertise.

Fleet of Equipment

Welltech has the largest fleet of Hidrostal pumps in the world, and the capacity to pump in excess of 14,000L/sec.

Welltech is renowned for quality solutions, so after years of research into pumps, we have aligned ourselves with Hidrostal, world leaders in waste water pump design and reliability. The Hidrostal pumps have screw impeller geometry and free passage design that can handle objects and laden liquids especially those solids that are raggy and fibrous which are prevalent in domestic and industrial waste-water.

We have pumps capable of pumping from 12L/sec (piccolo) through to the newest addition to our fleet – il padrino.. The il padroni’s are capable of pumping individual flow rates in excess of 2,100L/sec.

Every pump in our fleet has an identical twin to act as its contingency backup.

Our fleet not only consists of pumps, we also have a vast range of the latest state of the art Variable Speed Drives (VSD) fitted with SCADA telemetry and alarm systems. These drives can be interfaced with all Water Authority’s control centers enabling complete clarity of site conditions at all times.

Some of our other equipment includes;

• Magflo Flow Monitoring Spools

• Lampe Pipe Plugs

• Valves and fittings

• Custom, prefabricated temporary wet well pump stations

Once serviced and quality checked by our workshop team, all Welltech’s fleet of equipment will receive the tick of approval and be ‘Good to Go’. You can be assured, once 'Good to Go' it will be supported by Welltech’s guarantee of Commitment = Satisfaction.

Research & Development

Welltech have established a Research and Development program that constantly scours the world looking for and researching efficient and effective methods of Bypassing.

We believe that we have the largest capacity and most modern fleet of Bypass pumping equipment not only in Australia but in the World. All of our equipment is operated and supported by state of the art Variable Speed Drives (VSD) and ultrasonic level control all of which is interfaced with SCADA back to base telemetry.

Design

Welltech acknowledges and appreciates the complexities of delivering Bypass projects which are always of a highly sensitive nature. Welltech bring together our Management, Design and Engineering Teams to collaboratively analyse each project in detail.

With all potential projects, our in-house drafting division first prepare 3D dimensional layout images which provide ourselves and our clients a clear understanding of exact setup, footprints and layouts onsite.

On the award of a project, our drafting team further produce detailed P&ID’s, material take off lists, site layout plans and fabrication drawings for all items. Our Design Team ensure our clients understand exactly how and what the site will look like once the system has been installed.

Fabrication

Welltech’s in-house 3D Design and Fabrication facility has the ability to build custom pipe spools, pump assemblies and any components required for our Bypass operations.

Our world class facility merges the best people with the best equipment which in turn produces consistently superior results. This compliments our philosophy of keeping a tightly controlled system that produces exacting standards on stringent lead times.

This we believe is a necessary component of delivering accurate and timely Bypass projects every time.

Compliance

Our Team produces documentation covering all aspects of every project. These documents include but are not limited to:

• Concise Flow Management Plans

• HSE Management Plans

• Mechanical Checklists

• Electrical Checklists

• Design Drawings and Pump Analysis

• Site desktop analysis such as DBYD reviews

Welltech ensures at the planning stage the project deliverables comply with the client’s requirements whether it is regulatory and/or legislative obligations.

Our compliance not only satisfies the documentation deliverable but also ensures that we maintain an impeccable quality control process across all projects.

Health, Safety and Environment

Due to increased demand surrounding health and safety issues in the workplace our HSEQ team ensure accurate and comprehensive Health, Safety and Environmental procedures are produced and implemented onsite.

These documents can include but are not limited to the following:

• SWMS

• Take 5’s

• Risk and Environmental Analysis and Plans
