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.
