CEN/TC 165 - Waste water engineering

This document specifies the basic design and construction requirements for wastewater treatment plants for over 50 PT.
NOTE 1   Requirements for structures which are not specific for wastewater treatment plants are not within the scope of this document. Other ENs can apply.

NOTE 3   Although this document specifies the basic design and construction requirements for wastewater treatment plants for over 50 PT, many requirements are only technically and economically feasible at significantly larger sizes.

This document specifies design principles and performance requirements for sludge treatment and storage facilities at wastewater treatment plants serving more than 50 PT.

This document is applicable to lagoons and specifies the performance requirements for the installation of lagooning processes.
This document applies to wastewater lagooning processes treating municipal wastewater from combined or separate sewage systems and when used as a tertiary treatment.
NOTE   Lagoon systems are especially suitable for the treatment of wastewater where large flow variations occur (e.g. arising from surface water connections in the collection system). They are also especially suitable where large load variations occur (e.g. arising from fluctuating seasonal or industrial flows).

This document specifies general requirements for instrumentation and specific requirements for process control and automation systems on wastewater treatment plants for more than 50 PT.
NOTE 1   Because of the rapid rate of development of sensor and control equipment, this document is intended as an overview and uses examples and general requirements, not detailed equipment specifications. Detailed information additional to that contained in this document can be obtained by referring to the Bibliography.
NOTE 2   Although EC directives become matters of law in member states of the EU and some other situations, this standard is intended for wider use and hence those directives with clear technical guidance of a type that would generally be appropriate in a standard are referenced in the text and listed in the Bibliography. The alternative of listing requirements copied from directives would potentially create unacceptable conflict when directives are revised.

This document defines a methodology for determining and assessing the energy efficiency of Waste Water Treatment Plants (WWTP). The methodology aims at describing, in a systematic way, the various steps required to establish the Water Treatment Energy Index (WTEI) of a particular WWTP.
The methodology includes the classification of WWTPs in different types, identification of different stages of treatment, identification of key performance indicators (KPIs), overview of existing energy monitoring standards and the detailed description of the methodology, including a step by step guideline of how to apply and implement it.
The methodology is divided in 2 sub-methods that should be selected and followed according to the following goals:
- The Rapid Audit (RA) method allows for a quick estimation of the water treatment energy index (WTEI) based on existing information such as historical data pertaining to energy use records along with influent and effluent quality values. The aim of this methodology is to provide a WWTP energy benchmark, a rapid tool to identify energy efficiencies and inefficiencies so further actions can be planned, as well as to evaluate the impact of WWTP retrofitting.
The Rapid Audit methodology is detailed step by step in Clause 4 of this TR and can be used as a standalone document. The application of the Rapid Audit methodology to one real WWTP is shown in Annex A.
- The Decision Support (DS) method requires intensive monitoring across a WWTP of energy usage and water quality parameters that provides an accurate and detailed calculation of WTEI for each stage as well as its overall value for the plant. The goal of this assessment is to serve as a diagnosis of the functions/equipment in a plant that may lead to poor energy efficiency performance.
The Decision Support methodology is detailed step by step in Clause 5 of this TR and can be used as a standalone document. The application of the Decision Support methodology to one real WWTP is shown in Annex B.
