    Water Treatment Plant of Aposelemis, Crete

APOSELEMIS WTP

Challenge

The main objective of the project overall is related to the provision of safe, high quality water to the citizens and tourists of the cities of Heraklio, Chersonissos and Agios Nikolaos. Surface water from the Aposelemis dam is collected and transferred to the water treatment plant where advanced water treatment is provided.

The capacity of Aposelemis water treatment plant is 110.600 m3 per day for the treatment of A2 quality category water according to Annex A of Directive 75/440/EEC. Aposelemis WTP, uses the latest technology and its operation is based on a high level of automation, ensuring the production of high quality drinking/potable water, which fully meets the requirements of the Greek and European legislation.

Approach

The project involves the design and construction of the Water Treatment Plant of Aposelemis, part of the project "HERAKLIO AND AGIOS NIKOLAOS WATER SUPPLY FROM APOSELEMI DAM – CONSTRUCTION OF THE WATER DIVERSION AND COLLECTION - WATER TRANSPORTATION AND WATER TREATMENT WORKS”. The capacity of the plant is 110.600 m3/d and the water treatment chain consists of pre-ozonation, coagulation/sedimentation, sand filters, post-chlorination and clean water storage-equalization. Sludge treatment works include a gravity thickening unit and a dewatering unit.

The services provided by EMVIS include:

  • Coordination of the project design team
  • Detailed Engineering Design (hydraulic, process and mechanical design) leading to the construction of the works.
  • Support the Client in the selection of the electro-mechanical equipment
  • Support the Client in the start-up operation and the plant commission procedures

Impact

With the construction of the Aposelemis reservoir sustainable water resources management is promoted, overexploitation of groundwater is prevented and high quality water is provided to the cities of Heraklio, Chersonissos and Agios Nikolaos.

In addition the water shortage problem of the area is being resolved by strengthening the existing water supply system with additional quantities of guaranteed quality drinking water 17 million m3 as an annual average.

Research and Development

Research and Development

EMVIS has a continuous presence in National and European funded research projects (LIFE+, FP7, Horizon2020), in collaboration with Universities and Research Institutes. The fields of research cover all aspects of water resources and environmental management. The scientific output of these activities has been published in International Journals and Conference Proceedings and provided useful material, enabling the application of novel technologies and approaches to many practical problems.

Water Resources Management

Water Resources Management

The scope of the activity is Environmental Management with emphasis on aspects of water resources management related to the Water Framework Directive (2000/60/EC), the Marine Strategy Framework Directive and other National and European legislation relevant to, among others, potable water, bathing waters, surface waters intended for potable water supply, quality of ground waters and nitrate related pollution, urban wastewater treatment, effluent and sludge reuse and protected areas. In the context of these activities suitable mathematical models and GIS applications are widely employed in order to identify driving forces, pressures and pollution loads at a river basin level and to estimate anticipated impacts on surface, transitional and coastal water bodies as well as groundwater aquifers.

Challenge

Water information is highly sought after by many kinds of end-users, both within government and business as well as within civil society. Water touches virtually all societal and environmental domains and the knowledge domain is largely multidisciplinary.

Tools

wPOLIS

wPOLIS

wPOLIS is an interactive web map tool for calculating the temporal and spatial variation of Emission Limit Values for specified pollutants in a River Basin and also for defining exclusion zones where installation of new facilities is restricted due to water quality or other environmental criteria.

wPRISMA

wPRISMA

wPRISMA is an interactive web map application that provides information about water quality of surface water bodies. Its main objective is to identify areas or water bodies that experience significant pressures from diffuse and point sources of pollution.
