Every construction site in Spain falls under Real Decreto 1627/1997, which sets minimum safety and health requirements for construction sites. Annex IV regulates sanitary facilities: toilets, changing rooms, and rest areas. For contractors – general or subcontractors – this serves as the basis for ITSS (Inspección de Trabajo y Seguridad Social – Labor and Social Security Inspection) checks and for organizing work through ESS (Estudio de Seguridad y Salud – safety study) and PSS (Plan de Seguridad y Salud – site safety plan) documents. Below is what is inspected and where the waterless urinal meets the requirements.
What Annex IV of Real Decreto 1627/1997 Requires
Annex IV, Part A, Section 15 of Real Decreto 1627/1997 mandates that construction sites provide ‘servicios higiénicos’ – a sufficient number of toilets and sinks, separate for men and women (or with separate use), reasonably close to work areas. Real Decreto 1627/1997 does not specify numerical standards. These are set by the General Collective Agreement of the Construction Sector (VII Convenio General del Sector de la Construcción, Article 232): one sink and one shower for every 10 workers on site simultaneously, one toilet for every 25.
On sites with temporary or no sewage connection, these requirements are met with mobile sanitary modules with a storage tank, provided by rental operators.
Calculation of Urinals and Toilets
In crews predominantly composed of men – typically in frame assembly, masonry, roofing – separate urinals reduce peak load and queue times during breaks. Pi-Pi is mounted on the wall of a mobile toilet or inside a cabin.
ESS, PSS Documents and ITSS Inspections
ESS, prepared by the project organization before work begins, and PSS, developed by the contractor based on it, include a section on sanitary facilities. For PSS, Pi-Pi provides a manufacturer’s statement (material, country of origin), product technical specification, installed urinal photo, and connection diagram to the tank. Documents are sent via email. Violations are identified by the Labor Inspection (ITSS); they are subject to rectification requirements and fines.
Sun in Southern Regions
Construction sites in Andalusia, Murcia, the Valencian Community, Extremadura, and the Canary Islands operate in summer at +35…+40 °C in the sun. Under ultraviolet light, plastic ages over time: color fades, the surface becomes rough. With comparable stabilization, polyethylene oxidizes slower than polypropylene. Pi-Pi is made from LLDPE for outdoor use.
Frost Resistance for Northern and Mountain Regions
In the Pyrenees, Cantabrian Mountains, Sierra Nevada, parts of Castile and León, and Aragon, construction sites operate in winter at −10…−20 °C. Polypropylene homopolymer becomes brittle around 0 °C. LLDPE remains flexible down to −40 °C. For a contractor with a fleet operating across the entire peninsula, this is one material for all climate zones.
Compatibility with Cabin Tanks
The stepped outlet of Pi-Pi Ø24/32/40 mm fits hoses and connectors of these diameters. You can check the fit on your cabin’s tank with a sample.
Delivery to the Iberian Peninsula
Delivery from Pi-Pi (Estonia) to Spain takes 7–9 days with a standard carrier. For project orders, delivery to the contractor’s logistics warehouse is possible; terms are available upon request. For the Canary Islands, logistics are separate – details are clarified via email.
What the Urinal Does Not Cover
Pi-Pi is a component, not a complete solution. A cabin requires a toilet, sink, lighting, and heating. Pi-Pi covers one aspect – separate urine collection for men standing.
Conclusion
Real Decreto 1627/1997 is the framework within which every construction site in Spain operates. Pi-Pi is tailored to this framework: LLDPE remains flexible down to −40 °C and is designed for outdoor use, the stepped outlet Ø24/32/40 mm fits hoses and connectors of these diameters, and for PSS, we provide a manufacturer’s statement and specification. Installation takes 5–7 minutes. For a specific site, send a request – I will respond with a calculation and delivery terms.
