The location of the Maria Assumpta College in Santa Venera is in a campus of two others - Adelaide Cini and Guardian Angel. They are at a downstream area of an urbanised catchment and therefore, are susceptible to rainwater flooding. Philip B. Grech & Associates were commissioned by the Education Division to solve the problem and after a site investigation, a reservoir was designed and built to store and provide reuse potential for rainwater collected in pipework that was also designed and laid as a part of the scheme all over the Maria Assumpta College campus.
This was a challenging scheme in a site situated in the heart of an established community, with committed services and through traffic routes. The retrofitting of stormwater management while respecting existing historic infrastructure was particularly problematic. Philip Grech & Associates’ 5 year involvement in the scheme successfully transformed urban liabilities such as shoreline sewage overflows and flooded roads into soft landscape irrigation asset sources.
Previous Projects
Pama Stormwater Management
Philip B. Grech & Associates were commissioned by MedDesign Associates on behalf of PG Holdings to design the sewerage and stormwater for the redevelopment of an old suburban tile factory into a hypermarket “Pama” shopping village. The site was 32,000 square metres; a stormwater reservoir was incorporated for re-use and flood mitigation.
Mater Dei sewerage
Philip B. Grech & Associates in collaboration with Building Consultancy Services won the tender issued by the Foundation for Medical Services for the design, tender specification and supervision of works for a 400mm diameter 1.4km sewer main from Mater Dei Hospital to Gzira pumping station. The route passed half way around the University Ring Road and through the Gzira urban area, and cost nearly €230,000.
Sewer investigations and repair
Defective sewers at this institution for elderly priests were causing sewage overflows to the surface. It was established that certain lengths needed replacement as they were severely cracked and also badly installed. Rodent infestations aggravated the situation. The lengths were identified using closed circuit TV and then replaced while the sewers remained in service.
Sewer replacement
A reported blockage in the sewers at the Infetti training ground of Birkirkara FC was traced to defective pipework, after an investigation by CCTV, plotting, and analysis of the results. The sewers were taken up, relaid, and tested prior to being commissioned.
Cottonera Sewer Scheme
AThis commission included the infrastructural servicing of a redevelopment of a historical quayside at Birgu. Palazzi and vaults from the time of the Knights of St. John, together with the ex-Royal Navy Bakery, were transformed into an area incorporating a hotel and casino, apartments, a maritime museum, restaurants and a superyacht marina.
A Master plan for the sanitary sewers and stormwater facilities was drawn up by PBGA to service the three consortia on-site, and in total 4 pumping stations were installed. Sealed integral units were used for the smaller stations to avoid leakage possibilities. Pump-out facilities for the yachts, a first for the Maltese Islands, featured prominently. Integrating the services with fuel and power lines at sea level was also a major characteristic. Philip B. Grech & Associates also provided detailed design, site supervision and certification.
