Hendon case study
We were approached by Ivaro Ltd to facilitate a connection to the public sewer for a block of flats in Hendon, London.
Objective
We were approached by Ivaro Ltd to facilitate a connection to the public sewer for a block of flats in Hendon, London. In this instance, the sewer did not run past the new development in the Highway, and we found the closest public sewer to be 60 metres away in the carriageway, in the middle of a busy 4-way junction.
Our Solution
We had meetings with architects working on behalf of Ivaro Ltd, to help put plans together to detail the most cost-effective connection to the existing sewer. This included to connect onto the pipework laid by the developer at the boundary, after which point we extended the pipework into the road by 8 metres where we built a virgin inspection chamber in the Highway, and where the run would turn at 90 degrees before heading along the carriageway square with the kerb line. The new run of sewer would continue down the Highway for 60 metres to meet with the existing public sewer on a busy junction, whereby we would build an inspection chamber on top of the existing public sewer.
We had a Zoom call with an office-based engineer from Thames Water, and with our customer and their architect participating also, whereby we detailed our plans. These plans were approved in theory on the Zoom call, and the architect proceeded to compile drawings to this effect. These were then submitted as part of a Section 106 to Thames Water on behalf of our customer Ivaro Ltd, and the approval was given within a couple of weeks.
About the Project
With the Section 106 approval in place, we were then able to apply for the Section 50 licence with Barnet Highways. The application process included a site meeting with Barnet Highways whereby we detailed the technical aspect of carrying out the works in the Highway, and the traffic management that we proposed to use. For the bulk of the works we agreed on ‘give and take’ traffic management, with an official parking suspension for the duration of the works, to ensure that cars could not be parked in the vicinity of the works. For the connection point on the busy 4-way junction, we agreed on a 4-day road closure on one of the 4 roads, with this closed road being used to carry out the bulk of the work from, and where plant and materials would be stored. The 4-day road closure had to be done to coincide with a local school being closed on a Friday and Monday, and therefore our works on the junction would run from the Friday to the Monday, with us working over the weekend, to make the connection to the public sewer and to construct the new inspection chamber, with final tarmac reinstatement being done on the Monday, and all roads being opened again early on the Tuesday ready for the reopening of the school.
With the road closure in mind, we took care of the TTRO applications to Barnet Highways on behalf of our customer, and instructed a Traffic Management company to facilitate the road closure, including the vehicular diversion. This included us submitting traffic management and diversion plans to Barnet Highways.
Prior to us ‘breaking ground’ in the Highway, the application process to Thames Water and Barnet Highways for the Section 106 notice, the Section 50 notice and the TTRO application, took around 12 weeks in total. Once on site, the works were completed in just under three weeks, including the weekend work. All of these properties were occupied within weeks of the completion of our works.
Whilst working on Bell Lane, Hendon, we received many cups of tea from the locals, many of whom were extremely complimentary about the manner of our employees and the way in which the works were carried out from start to finish. A Koscher bakery existed within the works area, and the owner dutifully came out every morning with free cakes for all of our employees, which was an extremely heart-warming experience.

Customer review
Our customer was equally complimentary, and a pleasure to work with, and was kind enough to give us a Google review at the end of the works:
“Absolute pleasure working with John and his team. So considerate to the neighbours and polite. All works carried out on time and on budget. John was extremely thorough on explaining to me the process and works on site during the course. I will be using their services on future developments. Would strongly recommend them.”
