We have commissioned JBA Consulting to review our surface water drainage systems on St Mary’s. In order to assess the performance of these systems, Dene-Tech Services have been appointed to undertake surveys of the drains in Hugh Town, Porthmellon and Old Town from tomorrow, 10 March 2026.
We appreciate this is short notice, but we are keen to take advantage of the opportunity to get surveyors and their equipment over to the islands on 10 March, in order to minimise disruption to the public as much as possible at the start of the season. The surveys should be completed within 4 weeks.
We ask that the community helps us keep to this schedule by ensuring that access to the drain and manhole covers in these areas remains unobstructed between 8am and 7pm, from 10 March 2026 until the surveys have been completed. We will aim to update the community when we know more about how the work is progressing.
We are also writing to residents who are may be directly affected by the completion of these surveys. Although unlikely, it may be necessary for contractors to request to gain access to private gardens/yards in order to carry out the required work, and we would be grateful for full cooperation with these requests. All contractors will carry identification cards and will be working from a vehicle clearly displaying the company name. At no point will contractors need to enter anyone’s home.
The surveys are categorised as follows:
- Impermeable Area surveys
Impermeable area surveys determine the extent of a developed area which drains into the surface water drainage system.
- CCTV surveys
CCTV surveys pass a camera along a sewer to determine its internal condition.
- Manhole surveys
Manhole surveys establish the level and dimensional data of manholes.
Thank you in advance for assisting our surveyors to complete this important study.
