Water Treatment

Case Environmental recommends that all private raw water supplies (irrespective of type, age or construction) should, as a minimum, have filtration and disinfection fitted. This is because unlike mains water (which is normally chlorinated), private water supplies have no protection from bacterial contamination unless they are treated.


Whilst typically it is bacteria in the water that makes people ill, all private water supplies should have the appropriate treatment fitted to ensure the water is wholesome. As well as filtration and disinfection it is very common for many private supplies to require pH correction (most raw water is acidic and can dissolve metal fittings/pipe work) and, in some areas, manganese, iron and nitrate removal. In some cases further treatment is needed for additional parameters.


Case Environmental can sample the water in order to identify the at-risk parameters and determine what type of treatment should be fitted and the frequency of maintenance.


Case Environmental can also provide scientific advice and input to water utility engineering projects and process trouble-shooting.  Experience includes flash-mixer & clarifier design/problems, coagulant dosing points, pH correction, primary & secondary filtration, SCADA function, tank surveys and disinfection processes.


Services such as temporary scientific support, consultancy, project management and process investigation can be provided.


Found a well in your house?


Prior to the provision of public mains water (depending on area from the 1840s onwards) people did not have the luxury of water on tap.  Instead people commonly relied on hand dug brick/stone-lined wells, which was often shared with their neighbours.  These wells would often vary significantly in construction and depth, some being relatively shallow and some being over 100ft deep.


Without electricity or modern pumps, the water had to be pumped-out by hand; this was labour intensive and time consuming.  When mains water became common (and reliable) many of these wells fell into disuse and were forgotten about.


If you have house that is Victorian or older, there is a very good chance that somewhere you also have a well.  Often these wells are found during construction works and in many cases the cover is shockingly thin (especially if you have a 100ft drop).  We have seen wells previously covered by rusted corrugated sheets and just thin skim of concrete under drives and some under load-bearing, structural walls!


Once found the wells can make fantastic features and in some cases can provide water supply for various uses.  However, it is important to note that while the water would have historically been consumed untreated in its raw state, there is now much more knowledge and understanding about the pathogens and harmful contaminants that can be present in raw water.  Furthermore, with the ever increasing intensification of housing along with the threats of leaking sewers and numerous sources of pollution, it is very important that expert advice is sought before consuming well water.
