ATV-A 106E Notes for Users This ATV Standard is the result of honorary, technical-scientific/economic collaboration which has been achieved in accordance with the principles applicable (statutes, rules of procedure of the ATV and ATV Standard ATV-A 400). For this, according to precedents, there exists an actual presumption that it is textually and technically correct and also generally recognised. The application of this Standard is open to everyone. However, an obligation for application can arise from legal or administrative regulations, a contract or other legal reason. This Standard is an important, however, not the sole source of information for correct solutions. With its application no one avoids responsibility for his own action or for the correct application in specific cases; this applies in particular for the correct handling of the margins described in the Standard.
Foreword Water pollution control presents all those concerned with comprehensive tasks which are only to be solved through interdisciplinary organisation. ATV, the German Association for the Water Environment, has tasked its Specialist Committee 2.11 "Design and Construction of Sewage Treatment Plants", to make the complex procedures of modern planning clearer and more easy to grasp by means of an ATV Standard. The recommendations produced by the committee apply basically for all wastewater treatment facilities. With the design and construction of systems for the treatment of industrial wastewater special aspects have, if necessary, to be taken into account. The Standard is to provide a framework for the necessary considerations and engineering tasks with the design and construction of sewage treatment plants; this applies analogously for other wastewater treatment facilities. The necessary activities equally concern planners, construction sponsors and approving authorities. The necessity for the correct planning of wastewater treatment facilities arises from statutory specifications, and places on each form of wastewater disposal organisation a responsibility which is not to be circumvented. Only qualified and experienced specialists should be tasked with the production of planning documents. The result of the work of the specialist committee is the presentation of the complete planning, financing, approval and implementation activities as well as the time sequence and interdependence of all important individual activities. The Standard is divided into four main sections: Design Construction planning Additional information on important individual tasks Logic diagram. This Standard is not to be seen as a performance specification for the contractual processing of the planning and construction management tasks of planning and supervisory engineers and therefore deliberately follows neither a systematic form nor the terms for the performance descriptions of the German Regulations for Professional Fees for Architects and Engineers (HOAI), which applies for all fields of engineering. This HOAI is important for the engineering services with the planning and construction of wastewater treatment facilities insofar as it regulates the services to be provided and their remuneration. The performance of planning and construction management engineers are differentiated according to the HOAI into so-called "Basic services" and into "Special services", which are necessary for a successful project. Many of the engineering services described in this Standard are not included in the "Basic services" of the HOAI; they are "Special services" within the meaning of § 2 HOAI and supplement and October 1995

ATV-A 106E expand the performance contents of the basic services. The consideration of whether they are necessary or not must be carried out in the individual case. Furthermore, the HOAI system in "Object planning" and "Specialist planning", whereby, for example, the special contributions of the specialist planner for operational and process engineering, the technical fitting out of buildings and engineering structures, the supporting framework planning, the landscape planning etc. are to be seen as specialist planning contributions. Even this differentiation into object planning and specialist planning is not adopted in the Standard, particularly as the HOAI and its contents are subject to continuous up-dating. With this Standard there is deliberately no elaboration of the specialist fulfilment of the HOAI, rather the difficult and extensive dependencies and activities of the various participants in the planning and construction of a wastewater system are presented in an interdisciplinary way. The user of the HOAI is not relieved of working out, case by case, the services and the performance limitations for the planning and construction engineer from the HOAI, their official justification and the numerous available commentaries on the HOAI. This Standard can and will not be, from the aspect of contents, the determination of services in accordance with the HOAI, rather it is designed to ensure the quality of planning and construction supervision with the building of wastewater treatment facilities, independent of a framework of professional fees. The contents of the various (German) Federal State directives on design and construction planning remain unaffected. With the publication of this Standard, ATV Standard ATV-A 106 from 1962 "Advisory Leaflet for the Planning of a Sewage Works" (New edition in 1971 with unchanged text) is replaced.

Design
Preamble Preliminary studies, investigations, initial planning and approval planning are to be agreed between planner, construction sponsor and the approval authorities. The respective subsequent processing stage should, as far as possible, only begin after successful agreement. The design of wastewater treatment facilities must take account of the effects of construction and operation on other areas of the environment. The assessment must include comprehensively the environmental effects, in particular with regard to residence and recreation as well as to flora and fauna. In the interest of transparency of the decision process, it is recommended that the assessment is carried out in an independent environmental compatibility study with cost comparison in parallel to and in close association with the technical planning. If, for reasons of statutory specifications, an environmental compatibility examination is to be carried out, the authorities responsible for this should be engaged at an early date. It is to be established in what manner and in which scope the statutory requirements have to be taken into account. The planning documents are to be produced taking into account the generally accepted rules of technology and, in special cases (e. g. industrial wastewater), according to the status of technology. Generally accepted rules of technology are, for example, DIN/Euronorms, technical rules and standards (ATV, DVGW), safety regulations, construction regulations etc.
