At Idrostudi we are diligent at every stage of our work, whether we are studying a network or carrying out a measurement campaign, detecting leaks or studying proposals for network optimisation. The company has set up a DEPARTMENT specialises in the design and implementation of DETAILED TOPOGRAPHIC SURVEYS of wastewater and water supply networks, their special artefacts and appurtenance structures and MONITORING – MEASUREMENT CAMPAIGNS for water level, speed, water temperature, flow rate and pressure in both sewer and water supply systems strictly in accordance with HSE (Health-Safety-Environment) regulations. In relation to the measurements campaigns that involve staff entering in underground sewerage or tunnels, Idrostudi has conformed to the Occupational Health and Safety Management systems (OHS) ISO 45001. The surveys activities are computerized directly on-site with in-house developed web app, specifically developed for sewer and water supply flow monitoring. With our web app, it is possible to record the information of the manholes and flow rate and provide photos and videos of the pipes and instruments installation process.
Thanks to solid national and international partnerships, the group is able to guarantee the implementation of measurement campaigns with the use of state-of-the-art instrumentation (ultrasonic cross-correlation flowmeters, transit-time flowmeters, magnetic or insertion sensors, etc.) in order to DETECT LEAKAGE in the water supply systems and to asses Inflow/Infiltration phenomena (EXTRANEOUS WATER analysis and management) causing dilution in sanitary sewers thus decreasing the efficiency of treatment.
AQUEDUCTS, ADDUCTION, DISTRIBUTION AND RETICULATION FOR WATER SUPPLY NETWORKS
Idrostudi performs measurement campaigns for collecting flows and pressure records to provide updated systems input data for a pre-established time. The provided activities additionally cover the quality and functionality assessment of existing bulk meters and customer meters, designs and implements the isolation, flow measurements and pressure control of the DMAs, carries out step-testing for leakage detection, conducts detailed zone measurements of continuity, night flow and other leakage parameters to be used in conjunction with the hydraulic modelling for NRW management.
STORMWATER, SANITARY AND COMBINED SEWERS
Idrostudi designs, plans and carries out topographical sewerage network surveys collecting information on manholes, iron covers, cover slabs, invert levels, weirs, overflow spillways, lift stations, flood control gates, and any kind of sewerage appurtenance structures. Idrostudi provides the Clients with information concerning the location of pipe work and valves, confirmation of materials used and line and level of the pipes and sewers. CCTV inspections are also carried out for the identification of sewerage defects and faults such as cracks, displaced joints and obstructions.
One of the most promising activities offered by Idrostudi is represented by the sewerage in situ hydrometric monitoring for Inflow/Infiltration (I/I) study. The hydrometric measuring sensors are immersed in the wastewater in order to continuously record the level and the speed of the water (and consequently derive the flow rate), as well as the temperature. The analysis allows identifying a typical flow rate both in dry and wet conditions, to verify the correct functioning of the network and to quantify Inflow/Infiltration phenomena and their distribution in a sewer district.
WATER SUPPLY AND SEWERAGE SYSTEMS HYDRAULIC MODELLING
To learn more about the network and to design or modernise water networks or sections of the same, Idrostudi uses the most well-known calculation software to develop numerical models of constant and variable water flow rates. Idrostudi owns and currently runs different proprietary hydraulic and numerical models (MIKE URBAN+, InfoWorks ICM, Urbano Ultimate, MatLab) as well as license-free models (Storm Water Management Model – SWMM, EPANET) and in-house developed tools for network optimization, water balance tools, water loss analysis, NRW analysis tools, Inflow/Infiltration analysis tools.
All the mentioned software is integrated with CAD and GIS environment (ArcGIS, QGIS, AutoCAD, Civil 3D) and are compliant with international standards/protocols. The most appropriate model is chosen for each study based on the Idrostudi wide experience in using different sewerage network models.
INCLUSIVE CITYWIDE WATER SUPPLY AND SANITATION APPROACH
Our Key Principles to deliver an CITYWIDE INCLUSIVE WATER SUPPLY AND SANITATION project are based on COLLABORATION between many actors, including: national, sub-national and city/municipal governments; utilities and municipal service providers; business and the private sector; civil society, local and international NGOs; donors, bilateral and multilateral agencies and private foundations; as well as academia and, importantly, households themselves. Each component is organized in a UNIQUE WAY. Local actors need to ACKNOWLEDGE SHARED RESPONSIBILITIES and work collaboratively to chart their own path to providing urban sanitation to all. We specifically call on all actors to work based on four interconnected principles:
- prioritise the human right of all to sanitation
- deliver “safe management” along the whole sanitation service chain
- recognise that sanitation contributes to a thriving urban economy
- commit to working in partnership to deliver citywide inclusive sanitation
Our CITYWIDE INCLUSIVE WATER SUPPLY AND SANITATION policy will include the vision, missions, and goals of water supply and sanitation development as well as strategies to meet these goals. Each strategy is then translated into indicative programmes (and strategic action plans). The citywide inclusive strategy will cover:
- Technical aspects, including strategies and programmes for the development of (a) water resource availability, (b) water supply systems, (c) sanitary sewer services, (d) stormwater sewer services, and (e) micro drainage services.
- Non-technical aspects, including strategies for the development of non-physical aspects such as (a) community awareness and participation, (b) policy and regulation, (c) institutional capacity, (d) private sector engagement, (e) NGO engagement, (f) financing and tariffs, and (g) monitoring and evaluation.
We plan and design facilities towards the objectives of the Global Agenda
