Wastewater upkeep and restore specialist Lanes Group has carried out the primary spray lining venture commissioned by Scottish Water to rehabilitate chambers serving a big moist effectively.
The revolutionary venture has efficiently strengthened the 2 chambers on the outfall of the moist effectively at Decrease Largo, Fife, stopping the belongings from having to be excavated and changed.
Lanes Group, which is a framework provider for Scottish Water throughout the entire of Scotland, steered the answer after it was discovered that the chambers wanted to be sealed and strengthened.
The corporate carried out the work for Morrison Building, a framework contractor delivering design, engineering and development companies for Scottish Water.
Matthew Anderson, Connection Supervisor at Morrison Building, stated: “We’d wish to thank Lanes Group for making use of the revolutionary Hermes M-Coating system, along side ERGELIT dry mortars to those very deep chambers.
“They had been badly affected by hydrogen sulphide corrosion. The spray lining work saved us from having to install temporary works in excess of six metres deep to replace the asset. The carbon savings alone were huge.”
David Beveridge, Regional Gross sales Supervisor for Lanes Group, stated: “Except an acceptable no-dig rehabilitation answer was discovered, the one choice was to contemplate changing the chambers.
“This is able to have been a significant engineering job, carried out over many weeks, with important mitigation in place to make sure continuity of wastewater companies for wastewater clients.
“The solution Lanes provided, instead, was completed over six days, with all required outputs achieved. This was both highly cost-effective and extremely sustainable, with no inconvenience for customers.”
The spray lining was carried out by Lanes Group Sewer Renovation.
One of many chambers was fashioned from concrete rings and was 6m deep and 1.2m in diameter. The opposite was a brick-lined sq. chamber that was 6m deep and 2m extensive.
Every chamber was first cleaned by a remotely-controlled excessive stress water jetting system. Mortar was then injected into the joints of the concrete ring chamber to seal them.
In a ultimate course of, one other remotely-controlled rig was lowered into the chamber to spray-line its partitions with a specialist dry mortar.
The pc-controlled system mechanically accomplished 50 coats of every chamber to create a liner 10 millimetres thick, with the coating cured in 24 hours.
Lanes Group Sewer Renovation Technical Supervisor Gary Carey stated: “The material of the chambers had been broken by a lot of contaminants, together with raised ranges of hydrogen sulphide.
“The mortar we applied is resistant to these chemical compounds and creates a sealed drainage system with the required structural strength and long-term protection against water infiltration and leakage.”
Spray lining wastewater belongings is a way more sustainable than excavation and alternative, offering an answer with a smaller carbon footprint.
Usually, it’s also a lot faster, safer and simpler to hold out, utilizing much less gear and supplies and extra restricted confined house entry.
Gary Carey defined: “On this occasion, the moist effectively chambers have been situated simply off a single-track rural street however have been simple to entry by the small Lanes Group spray lining crew.
“Had the chambers needed to be replaced, the same would not be the case for an excavation team with the range of plant and materials they would have to deploy.”
