Water Quality

RPS has experience of planning and delivering large programmes of water quality improvements at least cost and best value.

Drinking Water Quality

Water companies are continuously looking at ways to improve the quality of drinking water to their customers. Sometimes this can be through improvements to the treatment process and sometimes through improvements to the quality and condition of the distribution network.

Water Quality Sampling

Quality sampling in sewers and water courses utilises specialised automatic samplers. These samplers can be triggered to sample according to different criteria, namely, Volume of Flow, Depth and Time

Samples usually need recovering from the sampler and delivering to a laboratory on a daily basis, depending on the triggering criteria. Samples are kept in a controlled environment to MCERTS specifications until delivered to the laboratory, so as to prevent degradation of the sample.

Water Quality Sampling is a specialised and intensive activity. RPS offer a comprehensive quality sampling and analytical service, including: -

Planning of the sampling exercise.

Pre-installation site survey.

Provision and deployment of sampling equipment and triggering devices.

Crew to visit the sampling site daily or be on 24-hour standby to retrieve samples.

Deliver samples to a laboratory.

Analysis and reporting of samples.


We can also arrange for the analysis of the samples for BOD, COD, Ammonia, total SS and any other pollutant.

Case Studies

Chemical Investigations Programme

Chemical Investigations Programme

United Utilities

The Water Framework Directive (WFD) sets out a ‘strategy against pollution of water’ and has a number of daughter directives which outline specific steps to be taken regarding certain compounds. The Priority Substances Directive was one of the first strategies established by the WFD.

The UK Water Industry Research (UKWIR) and the Environment Agency (EA) created the Chemicals Investigation Programme (CIP) to provide a substantial investigation programme into the management and control of the priority chemicals listed under the Priority Substances Directive.

RPS has been working on behalf of United Utilities undertaking the sampling and analysis of influent and effluent samples in order to assess the level of priority substances present within the wastewater network. Samples have been taken from residential and industrial discharges as well as from raw and final effluents at wastewater treatment works in order to model the input, release and end-removal stages of these substances.

Samples were collected, filtered into 14 different types of bottle, chilled and delivered each day to our laboratory at Letchworth. The project included sampling and analysis of treatment works’ effluent, in-works processes and upstream networks. It was completed on time in June 2012.

Water Mains Rehabilitation (DW5)

The Water Industry Commission for Scotland (WICS) is funding Scottish Water to deliver a £400m per annum Capital Investment programme following the publication of its Strategic Review of Charges 2010 (SR10).

Of that funding, £140 million has been allocated to Water Mains Rehabilitation work (DW5).

Based on its expertise, RPS was tasked to deliver network design and surveying services to deliver the Water Mains Rehabilitation works to Scottish Water. The aim of this project is to reduce the risk of water quality being degraded due to the condition of the distribution system, principally because of the presence of Iron and Manganese deposits.

The project commenced in 2010. To date, the main challenge for our designers has been to meet the quality output requirements for the lowest possible cost. A collaborative approach was identified at an early stage and the Design Teams joined the Delivery Teams in a co-located office. This opened communication lines and has been a key element within the project’s success and greatly increased efficiency.
