Leak Detection & Repair.

BRITON was contracted to investigate underground water loss and a residential housing complex containing 58 units.  The complex project involved various stages consisting of system loss testing, system mapping, mark-out and cctv/sonde pinpointing of joint and tapping band positions, isolation point installation, followed by acoustic and infrared detection works.  Once leak positions were located strategic excavation and pipe repairs followed by grounds reinstatement and site clean down.  The successful project resulted in the accurate locating and repair of 5 leak positions and provided substantial water loss savings to the client.

Village Water Loss

Our client, having suffering long-term high water usage contract BRITON to carry out water leak detection works over there 6 hectare village containing over 120 dwellings and multiple complex buildings, irrigation and fire systems with pipe sizes between 20mm and 150mm  The well planned systematic approach by the team involved minimum loss testing, area loss testing, a full site audit followed by overground acoustic and acoustic correlation to pinpoint the leaks. Followed GPR works to confirm pipe positions and potholing to expose leak. 10 leaks were located within scheduled timeline and estimate. We continued to to excavate and repair the largest leak on the 150mm pvc main.  The client was so impressed with or works we we contracted to continue on another village with unknown loss.

Underground Sinkhole Locating

BRITON was contracted to investigate a site for the presence of underground cavity's.  The operation involved Infrared and GPR surveying to identify the underground void created by historic mining works.  The successful operation identified a large void before a visible indication was present or worse a collapse.  Project completed safely, on time and on budget.

GIS Utility Mapping

Our client required extensive underground services mapping of there 150 acre site.  The 12 month project involved extensive non-destructive location works followed GIS based mapping.

Water Loss Investigation

BRITON Detection & Inspection was contracted to investigate a large volume water loss issue on a 14 hectare industrial property.  The busy site was loosing in excess of 170 Lpm and substantial works had already been undertaken to attempt locate the leak before Briton was engaged.  We undertook a strategic approach to the investigation involving full site audit and partial mapping of the 180mm mains and isolation testing.  Followed by IR,GPR and Acoustic works which enabled us to pinpoint the leak and have the position excavated and the leak repaired overnight.  Process exceeded customers expectations and provided huge cost saving immediately. Process was undertaken from start to finish of remidal works with 72 hours.

Campus Leak Detection & Repair

After suffering long term issues with water loss, system configuration and location, BRITON was engaged to sort it out.  The site spanning over 150 acres with extensive buildings and intertwining historic and modern piping networks from 20mm PE to 350mm AC.  The project involved extensive system isolation and configuration testing, gpr & pipe-tracing, remapping and full leak detection surveying. Once the bulk of the loss was located over 14 underground leaks were excavated and repaired over a 6 month period, including 350AC repairs, tapping bands & valves, general punctured PE pipes, various corroded galvanized & copper pipe-works repairs etc.  From initial engagement to completion of first stage of leak repairs resulted in a 83% reduction in minimum night flow loss and substantial cost savings to the client.  Since completion of initial project we have continued to support the sites underground water system ongoing monitoring, repairs and maintenance.

Dam Leak Detection - BOP

BRITON Detection and Inspection was contracted to carry out leak detection works for one of NZ largest Hydroelectric power providers.  Due to the level of complexity in the cooling outflow system and challenges involved to provide the necessary testing in the hazardous environments BRITON was the clients first choice to plan and undertake the operation due to not only our leak detection experience but our heights, confined space and gas testing certification, equipment and experience.  The project undertaken during a shutdown the the station and involved in-depth methodology, safety planning, gas testing and monitoring, manned confined space entry onto the large underground tank and other chambers, visual and camera inspection, followed by plugging and hydrostatic testing of the tanks, chambers and related 300mm pipework. The safe undertaking of the operation resulted in quantifying loss in different zones of the system and the location of the related defects causing the loss.  Project exceeding client expectations.

Pond Leak Detection - Golf Coarse

Lined ponds pose may challenges once underground loss occurs.  Briton Detection & Inspection was contracted to assist with the locating of pond leaks at a large Auckland golf coarse ahead of the dry summer months where the irrigation system relied on the water supply.  The process involved underwater diving and installation of pipe air bags to block the balance pipe and separate the 2 ponds and enable accurate loss calculation, followed by GPR & IR works to determine likely areas of loss.  Then ponds where pumped out to enable locating of the defects for repair.  We also assisted with the irrigation flow and isolation testing during the operation.

Village Water System Testing & Mapping

BRITON was engaged to investigate water loss in a residential village hosting several hundred dwellings and many supporting facility's.  The project involved various stages and consisted of study and review of known asbuilt's and council plans, isolation testing and shutdowns and substantial GPR & tracer locating and mapping of the complex system.  The end results consisted of accurate loss testing of the system, correction of as-built pans and additional configuration plans to enable future troubleshooting of the system.

Mineshaft Capping Investigation

Our client required investigation into the position and integrity of a historic mine shaft capping in a reserve area.  The project involved Infrared Void surveying and Ground Penetrating Radar (GPR) works over the entire area.  The operation resulted in the identification of the position of the capping, angle of the cap as well as the accurate identification of  a void to the side and underneath of the cap which was confirmed when the client excavated the position.  BRITON's unique approach to the location of sinkhole and voids has provided an impressive track record to our council clients.

Infrared/Aerial Water Pipeline Leak Locating - West Coast SI

After conventional water leak detection methods failed in locating a this moderate flow leak in a remote location 80's water pipeline at a depth of approximately 1 meter,  Briton Detection & Inspection was called to assist.  We successfully located the leak in the first hour of aerial survey works using our custom high res/high speed IR systems. The successful location of the leak provided instant relief to the mining operation.
