ASSET RENEWAL

Celtic Surveys | Leak Detection | Asset Renewal

Many of the existing mains networks are ageing and deteriorating and so it's often the case that pipe routes are not mapped, or over time their location has been lost. We provide a complete surveying and mapping service and this is the first step in being able to correctly assess and manage your network and needs. 

 

Once the pipework is located, the next step would be to understand the condition and serviceability of the existing network. Pipe sampling and non-destructive techniques are available to enable accurate external and internal assessments to be made. With this information, a design and build project can be established that meets your specific needs, targeting the areas of concern within the network. 

 

Whether your need for asset renewal is reactive or proactive, we have multiple techniques which can be mobilised to meet your specific needs. Often projects can require a number of different techniques to provide the most efficient overall solution. 

 

Ground conditions, surfaces, customer impact and environmental needs can all drive a need to explore trenchless technologies to minimise the impact of works. We can deploy small diameter impact moling for services and directional drilling for larger diameter pipework and these techniques can provide solutions where excavation is difficult. This could be used to avoid the excavation of a driveway or to cross major roads or rivers. Both techniques greatly reduce the need for excavation down to a launch and reception pit. These pits vary in size due to pipe size and technique.

KEDLESTON HALL

It was identified that the existing water supply to the old trough, was fed via a mains water feed from an onsite storage tank. It was decided that a more cost-effective and environmentally friendly solution would be preferable.

 

Following an onsite survey and feasibility study, two points of interest were identified to assist with meetings these needs. Firstly, there was potential for a large capacity of rainwater to be harvested on site.

 

Secondly, there was a redundant Second World War water main that ran the length of the site. This water main ran to within 100 metres of the desired location of the troughs. The old main was used as a sleeve and the new MDPE pipework was pulled through the main. This enabled a highly cost-effective method of covering the distance with a small amount of traditional open cut to complete the laying of the new supply.

 

Combining these two features enabled harvested rainwater to be fed to a tank supply and, in turn, utilisation of the existing irrigation pumps meant the transition to a more environmentally friendly and cost-effective method of supplying the troughs.

LIVERPOOL CITY COUNCIL

Celtic Surveys were approached by Liverpool Council to renew a section of 4” water main that was required to be completed by a certain deadline. We attended a site meeting with the client and agreed on a design and build strategy to facilitate the work needed, with a proposed timeline. 

 

750 metres of new 110mm MDPE plastic main was renewed with three new supplies to the existing tennis courts, athletic club and outbuildings. These were metered to ascertain water consumption going forward and provide future water management. 

 

Due to the works being completed in a public, open space, the need to restrict access to the work area was a key build parameter.

 

All work was completed on time and on budget.
