From the following pictures, it is patently obvious that Boreline Flexible Drop Pipe would be the most logical, most efficient and safest manner in which to tackle the environmental problems encountered at this site.
The site had been used for many, many decades with the effluent generated, being very toxic. Many extraction and monitoring wells were drilled to monitor and halt the movement of the contaminated groundwater towards an area of groundwater supply just outside the perimeter.
Due to the aggressive nature of the effluent, pumps and pipes would last less than 9 months. Breakdowns would often occur and the possibility of contamination outside the perimeter and an enlarged plume, were real and very probable.
Boreline, because of its ease of installation and retrieval and the fact that it does not breakdown chemically, was considered and specified. With Boreline, a broken pump could now be removed, replaced and be in back in operation, in less than 30 minutes.

The steel column is removed using a mobile crane

Removing the rigid column

At every 20ft section, the steel column has to be clamped and held so that the joint can be broken and the section removed.

Internal and external problems after 9 months

Surprise, surprise!! Internal growth. Note the external growth on the submerged section. This does not happen with Boreline, ever. Now here comes the easy part…

Connecting the Boreline

The power cable has been attached along the length of the Boreline and the pump cable connected. The Boreline fitting has been screwed into the pump and double clamped for extra strength.

Installation time

Installing Boreline by hand

The pump and Boreline are simply lowered into the well in one continuous length. The base plate is lowered into position.

It does make sense
