Planning water and wastewater plants with AutoCAD Plant 3D

Pumping station, elevated tank or wastewater treatment plant: this is where plastic, stainless steel and existing plant meet. We capture the existing plant by laser scan and set up AutoCAD Plant 3D with piping specs for PEPE – Polyethylene Polyethylene, a thermoplastic for gas, water and wastewater pipes. “PE 100” indicates the strength class (MRS 10 MPa). Background and sources ›, PPPP – Polypropylene Polypropylene, a thermoplastic for chemical, wastewater and hot water lines; more heat-resistant than PE. Background and sources ›, PVCPVC – Polyvinyl chloride Polyvinyl chloride. PVC-U (rigid, without plasticizers) for water and chemical lines, PVC-C (post-chlorinated) for higher temperatures. Background and sources › and stainless steel.

With us you will find solutions for your tasks.

Typical plants

  • Waterworks, pumping stations and elevated tanks
  • Wastewater treatment plants and rainwater treatment
  • Industrial water and wastewater treatment
  • Plant engineering for water treatment (series and modular systems)

Typical planning tasks

  1. Capture the existing plantElevated tanks and pumping stations are often cramped and poorly documented – the laser scan supplies the dimensions.
  2. Plastic piping specsPE, PP, PVC-U and PVDFPVDF – Polyvinylidene fluoride Fluoroplastic with high chemical resistance, e.g. for acids and ultrapure water. Background and sources › with welded, bonded and flanged connections – by SDRSDR – Standard Dimension Ratio Ratio of outside diameter to wall thickness for plastic pipes, e.g. SDR 11. A smaller SDR means a thicker wall and a higher allowable pressure. Background and sources › series in the piping spec.
  3. Series in plant engineeringSet up recurring plants faster with the same project template and the same piping specs.
  4. Documents for construction and operationOrthos, isometrics and bills of materials from the model; the point cloud remains as as-built documentation.

Piping specs and catalogs

For water and wastewater, the plastic catalogs (PE, PP, PVC, PVDF, GRP, plastic valves) are particularly suitable, along with stainless steel and valves:

  • Plastic – pipes & fittings – 9 catalogs
  • Stainless steel – pipes & fittings – 5 catalogs
  • Valves (DIN EN) – 12 catalogs

All catalogs with contents: ASEING Piping Catalogs. Your own piping spec? Size it in the Piping Spec Calculator – preliminary sizing, not a piping design. Existing catalogs are checked by the Catalog Checker.

Frequently asked questions

Can AutoCAD Plant 3D handle plastic lines?

Yes. Pipes, fittings and valves made of PE, PP, PVC or PVDF are in catalogs and piping specs just like steel. What matters are the right connections (welding, bonding, flange) and the SDR series.

Is a laser scan worthwhile for an elevated tank or a pumping station?

Often yes, because as-built drawings are missing or no longer correct. How many scan positions are needed is estimated by the scan project estimator.

Do you also plan complete wastewater treatment plants?

We support your planning team with AutoCAD Plant 3D, piping specs, laser scanning and project support. Process design stays with you.

DIN – German Institute for Standardization

“DIN” before a number means that the standard is published in Germany by the German Institute for Standardization.

DIN was founded in 1917 as the Standards Committee of German Industry. If “DIN EN” or “DIN EN ISO” precedes the number, a European or international standard has been adopted unchanged as a German standard.

EN – European Standard

European Standard, developed by CEN (general) or CENELEC (electrical engineering).

Every member country must adopt an EN unchanged as a national standard – in Germany as “DIN EN …”. Conflicting national standards are withdrawn.

DVGW – German Technical and Scientific Association for Gas and Water

Codes of practice for gas and drinking water installations (DVGW worksheets) and certification of components for these installations.

ASME – American Society of Mechanical Engineers

US engineering society. Its codes for piping, flanges and pipe dimensions apply in many plants worldwide.

ASME was founded in 1880. Well-known codes: B31.3 (process piping), B16.5 (flanges), B36.10M and B36.19M (pipe dimensions).

R&I – Piping and instrumentation diagram

ISO – International Organization for Standardization

“ISO” before a number denotes a worldwide standard of the International Organization for Standardization in Geneva.

ISO was founded in 1947. Its members are the national standards bodies; for Germany, this is DIN.
