Water Quality Impact Assessment - Kent

Water Quality Impact Assessment - Kent


Southwest Environmental Limited wear commissioned by a client from the Midlands, to undertake a Water Quality Impact Assessment in Kent. The assessment was for a proposed activity in a water body, where the water quality of said water body was very important to various stakeholders.

Luckily there was pre-existing monitoring data available from a pre-existing site which was utilised to form a baseline study.

The main risk from the activity was judged to be biological contamination of the water body. However, all the potentially impacted stakeholders would like not be affected owing to treatment of the water prior to use that would eliminate the biological contamination.

The Water Quality Impact Assessment also identified that the baseline levels of pathogens within the water body as existing were relatively high, this was likely to introduction for farm land and water fowl. As the levels of these pathogens in baseline sample data fluctuated according to rainfall, which in the case of farm land / manure at least would indicate run-off as a source.

ADF Daylight Assessment - Lambeth SW4


Southwest Environmental Limited have recently issued a ADF Daylight Assessment Report for a project in Lambeth.

The design of the project was most unusual. It consisted of a dwelling being built in a gap in a row of terraced houses. Instead of using the full available height to match the existing houses, the development makes use of a basement and a ground floor level only. As such is fairly unique in appearance certainly when considering the immediate vicinity.

Basement & Ground Floor Only Design

This low level construction obviously aided in the minimisation of any day lighting or sun lighting issues, and the dwelling met all criteria relating to external impacts as described in BR209. Interior lighting was found to be excellent throughout with ADF values exceeding guide minimum values by some margin.

SWEL regulatory carry out Sunlight and Daylight Assessments across the Greater London Area. Our reports are well received and we pride our selves on a quick turnaround, often in 5 working days or less.
